| |
| General The purpose of this routine announced inspection.was to review the corrective actions for previously identified matters; items reported by the licensee; reactor startup operations; act-'on on reactor operations.
| |
| bulletins; maintenance activities during shutdown; and an inspection relative to fire stops for electrical cables and penetrations.
| |
| ~
| |
| : 3. Post Refuelin Startu Testin The inspector examined procedures and associated test data to verify that post refueling startup testing was conducted in accordance with require-ments.
| |
| Procedures and data relating to the following were reviewed:
| |
| a., Contxol Element'ssembly position checks.
| |
| : b. Boron reactivity worth.
| |
| : c. Measurement of temperature coefficient of reactivity worth.
| |
| : d. Minimum shutdown boron concentration with a control element assembly completely withdrawn from the reactor core.
| |
| .(continued)
| |
| : e. Control Element Assembly worth for each bank.
| |
| : f. Checkout of the recently installed variable over power, trip circuitry.
| |
| : g. Partial power ascension testing.
| |
| Completion of this review will be performed during a future inspection.
| |
| The post refueling testing procedures were reviewed for adequate definition of scope, objective, prerequisites, precautions, limitations,,acceptance criteria checkoff lists, deficiency control and resolution, valve lineups, plant conditions, and proper approvals. No deficiencies were identified by the inspector.
| |
| 4~ Abnormal Occurrence'Re orts '(AOR's)
| |
| . Abnormal Occurrence 74-18, 75-03, 7S-OS and 75-07 thro+'e ?5-11 were reviewed during this inspection. The details of each are summarized in the following paragraphs. The inspector's effort was directed't verification that:
| |
| : a. the details of the event were clearly reported in the 10-day letter;.
| |
| : b. 'he cause was clearly identified;.
| |
| : c. the corrective action indicated had been completed; 'and
| |
| ,d. the event and indicated corrective. action was reviewed and evaluated in accordance with the Technical Specification.
| |
| No discrepancies were noted. However, AOR 75-05 does constitute a, deficiency, since the decirculation actuation set point had drifted upward in excess of the TS requirement. Corrective measures have be'en taken by
| |
| . the licensee as described below.
| |
| : a. AO 74-18 and AO 75-03 Failur'0 of Diesel Generator Breaker Override The two Abnormal Occurrences reported -by the 1'icensee are similar since both resulted, during Surveillance Test ST-ESF-2 (Safety Injection Activation), in the fait.ure of lockout relay 86-OR/1ADl to trip. As reported by the licensee, AO 75-03 is the fourth occurrence of a relay failing to operate due to wir'e lug interferences.
| |
| To prevent repetition of this occurrence the licensee has completed a permanent fix which would eliminate. the wire lug interference problem as follows:
| |
| (1) Removal of the relay covers and cut off all but the last 3-3/4" of the cover which protects the coil. Arrangement of the relay (continued)
| |
| IE Inspection Report No. 50-285/75-01, Details 1, paragraph 8
| |
| | |
| 4 0- ~
| |
| wiring to assure sufficient contact clearance and 'installation of the covers over the coils.
| |
| (2) To prevent dust and other foreign material from falling into the relay contacts, installation of a l(8" Micarta panel above the top rows of relays. This panel was placed between the top of the relays and the bottom of the amber status lights.
| |
| (3) 'o prevent dust from collecting on the relay contacts, air filters were installed on the louvered panel doors which are intended to remove all particles larger than two microns in diameter.
| |
| This matter is considered closed.
| |
| ~~
| |
| AO'75-05 Recirculation Actuation Si nal'Set Point'Drift During review of SIRH Tank I.evel Channel Can~br .+"..~s ST-ESP-7, P.3 it was discovered that the as Sound pressure switch settings for the Recirculation Actuation Signal had drifted upward in excess of the Tqchnical Specification section 2.0 setting specified in Table 2-1, Item 5. This set point is 16" + 0" 2" and initiates Safety Injection Recirculation. In addition, the level being maintained in the SIRE'ank was found to be approximately 15,000 gallons below :
| |
| the requirements of Technical Specification section 2.3(1)a which requires a minimum level of 283,000 gallons of water in the SIRE Tank.
| |
| The inspector determined that calibration procedures have been changed to provide low level'nd high level alarm set points of the SIRE Tank to 185 inches and 193 inches respectively. This low level alarm alerts the control room operator when the level decreases to approx-imately 296,000 gallons. The calibration procedures were also changed to calibrate the Safety Injection recirculation set point to 16ll + Oll 2II The calibration set point was previously set at 16" + 0.2"'which is 0.2 inches above the Technical Specification limits. A design change has been prepared to install switches with a lower pressure setting in the safety injection recirculation control circuitry. The pressure switches have not been installed. This AOR remains open.
| |
| These infractions were identified by the licensee and were reported in a timely manner. Corrective actin ha" been taken. No additional information is needed for these items of noncompliance at this time.
| |
| AO 75-07 Failure of Diesel Breaker'IADl to Close on Dead'Bus Durin I.oss of Off-Site AC Power At 0031 hours on March 13, 1975, main transformer Tl tiipped on an indicated internal fault. Both diesel generators'uto started and (continued)
| |
| | |
| <<10-came to rated speed and voltage due to loss of voltage on 4160 volt buses '1A3 and 1A4. Diesel Generator ii2 breaker lAD2 auto closed on bus lA4; however, Diesel Generator breaker 1AD1 fail.ed to auto close on bus lA3. The operator then manually. closed ,, .",
| |
| breaker lADl'by control switch.'' This occurrence was'caused by.
| |
| 'the failure of the operator to trip SI-1A breaker.
| |
| Operating personnel were briefed by the Operations Supervisor on the operator action required during loss of off-site AC power.
| |
| It was.brought to their attention that Emergency Procedure 83 documents the action required by the operator during loss of off-site .AC power.
| |
| This matter is considered closed.
| |
| , AO 75-08 Failure of Hi h Pressure Safety In ection Valve HCV-311 to 0 en on a Sipral from the Control Room.
| |
| The High Pr'essure Safety Injection Valve HCV-311 failed to open on control switch command from the control room. The reversing interlock at the combination breaker/starter for HCV-311 was not making proper contact. Also, a normally open contact had been installed instead of a,normally closed contact. Preventative maintenance had been performed on this breaker/starter prior to this occurrence and the breaker/starter was improperly reassembled.
| |
| The inter'ock:: s reassembled and manually actuated to verify operability. HCV-311 was then electrically operated by control switch from full open to full close to full open twice. The valve, its combination breaker/starter, and the reversing interlock operated properly.
| |
| This matter is considered closed.
| |
| AO 75-09 Failure of Raw 4'ater Backu Valves HCV-401E and HCV-2808D to 0 crate During performance of Surveillance Test ST-Rfi'S-l, raw water backup valves HCU-401E (raw water supply to UA-1B) and HCV-2808D (raw water return from SI-2A) failed to operate on signal from the control room.
| |
| The failure of HCV-401E to operate 'was attributed to dirt in the valve positioner. HCV-2808D failed due to a solenoid which had failed to operate.
| |
| The pneumatic relay orifices on the positioner of HCV-401E were cleaned and the valve was retested satisfactorily. The solenoid was replaced on HCV-2808D and the valve was retested satisfactorily.
| |
| This matter is considered closed.
| |
| AO 75-10 Failure of Backu Se uenccr to Actuate huxiliar Rein Charging pump, CH-lC, and containment ventilation fan, Vh-7C, failed to sequentially start from the backup sequencer (Sl-2 and 52-2)

| |
| <<11-during Surveillance Test ESF-2. A test and inspection of the relay logic chain revealed that the contact from the timing relay which energizes the auxiliary re3ay was contaminated.
| |
| The relay contacts were burnished and the logic chain success-fully tested. CH-1C and VA-7C backup sequencer rela'ys were activated by simulating a pressurizer pressure low signal, timed out properly and did start the charging pump and containment fan' This matter, is considered closed.

| |
| HCU-401A and HCV-401C could not be reopened by the control switch with the CIAS signal present even though a flow of approximately 1500 gpm had been established.
| |
| The actuation set point on FC-417A was found to be set high so that normal flow could not actuate it. The set point was changed to its'proper operating point and the valves were tested to prove proper operation under a CIAS signal.
| |
| A means of locking alarm settings with a screw is being instigated by the licensee.
| |
| This matter will remain open.

| |
| | |
| Drawin s and S ecifications The inspector reviewed design drawings and specifications prepared by Gibbs, Hill, Durham and Richardson, Inc., and determined the status of the licensees actions relative to IE Bulletins 75-04'and 75-04A. The specification is contained in detail in contract No. 765, dated 7/69, with Commonwealth Electrical Company. The contract (specification) also references the pertinent drawings which were reviewed by the inspector.
| |
| The specification required fire stops for vertical tr-.y runs in excess of ten feet. The method used was requ'ired to be reviewed and
| |
| .approved by the engineer. Slots and openings in walls and floors
| |
| -through which cable trays pass and conduit sleeves, .slots and open-ings were also required to be framed and sealed with fiberglass, or other suitable material. The licensee's representatives indicated
| |
| :-.that only fiberglass'had been approved and utilized. The licensee also indicated that no other fire retardant materials were utilized except that fire tape manufactured by Irvington Company was utilized
| |
| =
| |
| at points within the control room cabinet base as wrapping for i individual cables at the floor penetrations.
| |
| Visual Observation The areas which were viaually examined by the inspector were:
| |
| (1) the Cable Spreading Poom; (2) portions of the Auxiliary Building, and (3) individual compartment within the Reactor Control Room.
| |
| Details of the installation'appeared to be in conformance with the specification requirements. However, it was noted that several of the wall openings did not appear to be completely sealed with fiberglass.
| |
| Small openings were observable. It was also noted that tendon grease was leaking at the juncture of the seal between the containment and the auxiliary building. This grease had leaked down and around electrical penetrations C7 and D7 and was formin pools of oil near the penedrations. This finding was also noted in the QA audit discussed in section 10.f of this report. The licensee was informed that these matters would remain as an open item.
| |
| Fire -Protection and Insnections An extensive fire and smoke detection alarm system was also installed under contract 765. The system utilizes PYR-A-LAF~1 ionization, photo-electric, and thermal detectors in combination with a main control panel in the control room, and remote alarm devices. The area system monitors 32 zones within the containment, auxiliary building and turbine rooms. The main control room panel provides annunciation and will indicate the zone. It also provides an annunciator for failure of power to the system.
| |
| (continued)
| |
| | |
| In con)unction with the detection system Oper'ational Instruction OI-FP-6-1 provides for a weekly fire protection system inspection and test. It includes operational checks of fire pumps, water systems, CO 2. chemical extinguishers, sprinkler systems, hose cabinets and a housekeeping inspection including not needed or .
| |
| unsafely stored volatile or combustible materials.
| |
| "Emergency procedure EP-10-1 provides for the steps to be taken in the event a fire occurs in or threatens reactor safeguards equip-ment, reactor protective equipment, or other equipment vital to the safe operation of the plant. This includes, use of the local fire department and a react;or trip according to emergency procedure Ep-l.
| |
| The existing fire extinguishing system provides:
| |
| Sprinkler for the turbine lube oil handling equipement; (2) Sprinkler for the turbine room basement; (3) Hose stations for the immediate vicinity outside the entire plant; (4) Hose cabinets inside the turbine building and the intake structure; (5) An automatic (heat sensing) deluge system for the main transformers two auxiliary and two house seismic transformers; and, (6) Local portable dry chemical and carbon dioxide extinguishers.
| |
| Present Installation Practices
| |
| 'o determine the present OPPD practices relative to electrical instal lations, the inspector reviewed two maintenance orders for work per-formed during the refueling outage, .
| |
| MO'8182, dated 5/2/75, Installation of Shutdown Cooling Valve Inter-lock, also discussed in section ll.c of this report, utilized four conductor ~)10 AUG cable, Cerro Firewall, which was certified by the Cerro '!fire and Cabl'e Co., by type test to have exceeded the require-ments of a post steam exposure flame resistance test. Minimum post ignition burning was recorded as 23.6 minutes; circuit integrity exceeded 15 minutes and no self sustaining flame was observed. Exist-ing space containment penetrations, cable trays and new conduit were utilized. Fire stops utilized the existing fiberglass where walls and ceilings or floors were penetrated.
| |
| MO 7653, dated 3/3/75, Loose Parts Monitoring System, was installed essentially as described above except for the cable utilized. .The cable utilized was 2 conductor Raychem-Flametrol'(Firewall III}which (continued)
| |
| | |
| k was certified as exceeding the requirements of 'IEEE 383. Fire-wall III is composed of 30 mils of flame retardant XLPE'nsulation covered with 45 mils of flame retardant neoprene.
| |
| Status of Re 1'o IE 75-04 and 75-04A OPPD has indicated that they will complete their review relative to IE Bu letins 75-04 and 75-04A and submit a .reply to NRC by July.l, 1975. As part of this review a QA audit was perfo: d on March 19-20, 1975,'o examine and evaluate housekeeping, cleanliness practices, and other activities related to fire prevention and protection. As a result, one of the recommendations was to remove= the tendon grease from the containment'all and investig'ate "a 'method "o'f el'iminating'the 'source.
| |
| 75A-1 Charcoal Filter Efficienc On February 21, 1975', OPPD received, from American Air Filter, verbal results of charcoal efficiency testing for charcoal filter beds. The results confirmed by letter on February 24; 1975, indicated an elemental iodine efficiency of 98.02% and 98.82% from two different lots of charcoal. The indicated efficiencies were less than the 99.5%
| |
| required by TS 3.6(5)d. This was reported to KtC by letter 2/21/75.
| |
| t A request to revise the TS acceptance criteria downward to 95% was forwarded to licensing and subsequently approved on 4/30/75.
| |
| 75A-2 Deterioration of Secondar Insulation 4KV Non-Scare ated Phase Bus Duct On March 31,.1975, deterioration of secondary insulation of 4 KV non-segregated phase bus duct was discovered while performing preventative maintenance on the 4KV indoor bus duct. This was reported to NRC by UE Report 75A-2, dated 3/31/75; Primary insulation of the bus duct 'is provided by separation of the phases from, each other and from gound. The 'secondary insulation
| |
| .which failed was a redithermo-setting plastic approximately one-tenth inch thick provided .by General Electric. The failure appeared to be the result of expansion of the material to a point of cracking.
| |
| Corrective action recommended by General Electric has been compl'eted in accordance with HO 7661. The procedure called for removal of insulation except where it was ciacked three inches or less, and taping of all bus ducts with Ho. 202 Irrathane tape and then with No. 70 Scotch Silicone tape. All bus.ducts were inspected, repaired and returned to service.

| |
| 'On April 15, 1975 OPPD reported to the NRC in UE 75-3 that the Q ~
| |
| secondary inhibit, valve HCV-348 as described in FSAR section 9.3.2, for did not in fact exist. Paragraph 9.3.2 describes a primary and seconda'ry inhibit to prevent opening shutdown valve HCV-349 when the RCS pressure is above 250 psi. 'cooling The primary inhibit described comprises pressurizer pressure tran'smitter PT-105 and auxiliary relays in the starting circutis of each valve motor operator. The described secondary inhibit is "a torque switch in the motor operator for valve HCV-347 which wil'1 prevent the valve opening if reactor coolant pressure is excessive."
| |
| The UE report stated that a secondary pressure sensing interlock for HCV-348, in addition to the "existing interlock, would be installed during the refueling outage.
| |
| The inspector verified that redundant pressure sensing intex'locks had been installed on both HCV-347 and HCV-348.. The work was performed in accordance with YO 8182 dated 5l2/75 and approved by. the PRC. OPPD is in the process of submitting these changes to Licensing for their 'review.

| |
| Special inspections were conducted on April 24 and 30, 1975, to deter-mine the plant status in regard to the provi ion of acceptable fire stops and flame retardant seals Eor electrical penetrations.
| |
| The ma)or inspection effort was an inspection tour of the electrical pcnetrations in the following 'area Control room Cable spreading room Auxiliary equipment and ventilation room (above control roon) 1)iesel generator roomed Portions of the Turbine building
| |
| ~
| |
| Portions of th'e Auxiliary building The inspection included review of' representative sampling of completed plant work request and modirication request for..s, plus discussions with the Assistant Plant Electrical/~laintenance Supervisor, and the Assistant to the 1janager.

| : b. Pire-Retardant ".hterial.
| |
| Plamemastic 71A manufactured by the Dyna-Therm Corporation.
| |
| This is a water base material which is non-flamable at all
| |
| . times.
| |
| C~ Sealant t<aterials The sealant materials which are packed in around the electrical cables in the electrical penetrations are all of the inorganic
| |
| 'iber insulation type of material; the primary material used at this plant is an inorganic thermal insulating material manufactured by the Babcock and Wilcox Company bearing the trade'ame "Koawool". Thus, in summary, none of the materials
| |
| ~
| |
| used in scaling and fire retardant coating of these electrical penetrations are at any time flamable.
| |
| : d. Penetration Sealant and Flame Retardant Specifications Detailed penetration sealing, fire zeta".dane application, and fire-stop specifications aze provided for ten different types of penetrations. These specifications are provided by Bechtel
| |
| ~
| |
| Company. on drawings E-178 and E-179. These specifications were reviewed by the inspector prior to the physical examination of the various electrical penetrations in the plant. Several minor deficiencies were observed as follows:
| |
| h I
| |
| (l) At several electrical penetration fire stops, the flamemastic 71A fire retardant material was observed. to be cracked, apparently due to shrinkage upon drying. This cracking up to < inch in width, did not provide a pressure/smoke seal around the Sire-stop.
| |
| (2) A diesel generator guarded cooling water line (pipe within a pipe) was not sealed at its exit from the diesel generator room. This is a 30 foot s'ection of 12 inch horizontal pipe. All other lines or openings were sealed or had automatic closure devices.
| |
| | |
| I 0
| |
| | |
| (3) One penetr"t:i.on, containing onlyI power and cont:rol cables for 'the electro-hydraulic control of .the turbine speed cont:rol, had only the marinice fl,.me stop. There were no other trays or. penetrations within t:hree feet of this pene tra t:ion.
| |
| 'f At the time of thi's in p'ection the Licensee was in t: he process examining all electrical penetrations in resoonse to 1E Bulletins 4i'o. 75-0'i and 'lo. 75-O~iA. The licensee reported that they had found one penetrati'on with a missing fire-stop and others that xequired dditional I:oawool and/or "lamemastic 71A. The inspector observed that these corrective act:ions were being made using the specifications ident:ified above.
| |
| The Licensee has stat:ed the intent to correct any deficiencies found, as expeditiously as time and plant conditions allow.
| |
| l These three deficiencies are not considered as immediately serious by the inspectox'ince they pose,no .,fire propogation threat, but rather a smoke control problem. This plant utili~es a multi-..ode ventilation syst: em whi.ch is designed to assure that smoke from any other portion of the plant can be prevented from ent:ering the control room or can be swept from the control room if it originates in the control room. As a back-up measure, the inspect:or observed that there 'axe four self-supporting air breathing masks available in the cont:rol room.

| . lt., Current Practices I
| |
| Discussions with the Assistant Electrical/.'faintenance Supervisor, plus a review of plant work request and modification files indicate that disturbing tnese sealed electrical penetrations to pull in new cable or re..ove old cable is an infrequent occurrence. Formal procedures or instructions are not issued, however, .according to the Licensee, the craftsmen return the penetration to its original status by using the specifications ident:ified in item 1-d above.
| |
| .The Licensee does not believe that. individual penetration seal testing to insure th .t a total pressure seal exists is necessary fox penetrations other than containment boundary penetrations-This position is based on the fact that the various plant ventilation control systems are designed with sufficient
| |
| 'ndependence to permit sweeping of smoke from the various portions of the plant without the smoke being introduced into
| |
| | |
| 2 I
| |
| I the control room. The separate control room ventilation system i designed with the capabili.ty i to purge any smoke originating in the con'trol room directly ty/agi/osphere, or to operate in a recirculating, filtered~ mode. -" Thus, the Licensee does not intend to perform jndividual penetration seal tests. They do intend to adhere to the penetration specifications of item 1-d above, in providing a flame stop, flame retardant, fire barrier type penetration with reasonably tight smoke limiting seal. The inspectors review of these design specifications and tne Licensee's final Safety imalysis Report indicates that neither specify that a:".casu able pressure scale:.ists, but rather that a "fire barrier" eyists.

| : 2. Sco e of Ins ection of Fire Barriers for Cables The inspection included an examination of (1) construction specifica-
| |
| 'ions for location and installation of fire barriers and compartment boundry seals for safety related cables and utilization of fire retardant coating on cables, (2) licensee's action pursuant to IE Bulletins Hos. 75-04 and 75-04A, and (3) a tour to determine extent of conformai>ce to overall fire barrier requirements.
| |
| 3-. Construction S ecifications
| |
| ~ ' In 1968-1969 that time, A program was PG&E analyzed all thermal plant load centers and, at embarked upon a program to separate units electrically.
| |
| also initiated to improve penetration and cable resistance to fire by the use of flame resistant insulation and fire stops. The Company's Engineering DepartmIent subsequently issued a manual entitled "Thermal Electric Design Standards."
| |
| Accordingly, the licensee has been backfitting Humboldt to the new construction standards. The fire and smoke barriers used between the feed pump room and the reactor control room circuit consist of kaowool, Hartinite (Johns-Hanville product composed of incom-bustible asbestos fibers, diatomaceous silica and a hydrothermally produced inorganic binder) panels and Flamistic 71A as a sealant and fire retardant on top of the Hartinite.
| |
| Barriers are only needed between the feed pump room and the control room since that is the only area where there are cable trays. All cables leaving the pump room going into the refueling building and drywell are carried inside of conduits. The conduit is frequently sealed with a moisture barrier of Dow-Corning silicone compound 732 or 738. The Construction Department mistakenly used some of this compound for the fire barriers to seal cabling that was disturbed during the last refueling outage. This will be removed during the forthcoming June refueling outage according to the licensee. (This error fuse of flamable material] was discovered subsequent to the licensee's response letter of April 23, 1975 which states, "All o seals used on floor and wall penetration seals are nonflamable.")

| : 4. Examination of Fire Barriers
| |
| .A tour. of'he facility was conducteu 'o examine the location and installation of. 'fire barriers and the utilization of fire retarding coating (Flamemastic 71A) for safety related cables. Specifically included in .the 'examination were the penetrations leading into the control cabinets and switch gear in the control room and the penetrations leaving the feedwater pump room (cable spreading room). .The safety related cabling leaving the pump room was encased in conduit.
| |
| It was found that the licensee had adhered to the construction specifications for fire barriers, except for the cabling that was disturbed during the last refueling outage. The inspector tested a small sample of Dow-Corning silicone compound (rubber-like in appearance) with a match. It ignited easily and sustained combustion until all of the surface area had burned. It could not be reignited without first removing the outer crust that had formed. As pre-viously noted, the use of this material was a construction error and it, will be replaced with Flamastic 71A in areas where it was used as part of the'fire barrier.
| |
| Five large cardboard boxes were found stored on top of pull box Ho. 02 through which the principal. safety related cables pass that lead from the feed pump room to the refueling building. (The use='4 0 iqw c' war in rasal 1 hnv, fAp, vari])tidhnf r harm>; c les gg v rela i p(N

| cabling is discussed in the. licensee's report to the Commission "Failur i'!ode Analy'sos'of Re'c.or Protection Systems,""-'. .-'ntitled
| |
| -dated January 20,"1970.) The boxes were leaning against the ver-t'ical cable trays leading into the pull box. They were promptly removed and satisfactorily stored by the licensee.
| |
| 1 Haintenance and Hodification Procedures Plant maintenance and modification procedures do not specifically require adherence to the construction procedures for fire barriers.
| |
| General policy dictates that systems disturbed by these activities be returned to their original state as stated in the licensee's response of April 23, 1975, "All maintenance during periods of operation is reviewed by at least the Shift Foreman and the cognizant
| |
| 'taintenance Foreman who assure that the work is carried out in accordance with established Company Accident Prevention and Fire Prevention rules. In addition, the Shift Foreman and Supervisor of Operations review maintenance activities to assure that the limiting conditions for reactor operation outlined in the Technical Specifications are maintained."'
| |
| | |
| Existing "Company Accident Prevention and Fire Prevention Rules" address several of the areas identified in the IE Bulletins. The licensee was examining existing policies and procedures with plans to modify or expand as appropriate the remainder of items as they apply to construction, modification or maintenance activities.
| |
| According to the licensee, these policies and procedures will be included in the Plant Administrative Control Hanual. This Hanual is a part of the operational quality assurance program scheduled to be completed by December 31, 1975. In the interim, all such activities which could adversely affect reactor safety-related equipment will be 'reviewed by the Plant staff using the guidelines of IE Bulletin 75-04 and 75-04A. This interim procedure was to commence by Hay 23, 1975.
| |
| ~Emer enc Procedures for Alternate liethods of Core Coolie The alternate methods for core cooling and status of'he "spectrum of alternate paths" were reviewed with the licensee. The Plant Emergency Procedures provide alternate methods for accomplishing an orderly plant shutdown and cooldown in case of loss of normal and alternative shutdown and cooldown systems. The spectrum 'referred of alternative paths available to supply cooling water and remove decay heat 'is included in the Emergency Procedures and in the Equipment Description and Operating Instructions. In order to place this )nformarion in a more concise form, an ouLline of the spectrum of alternative paths available to supply cooling water and remove decay heat was being prepared as a part of the emergency procedures. This was scheduled to be accomplished by Hay 23, 1975.
| |
| Maintenance Plant maintenance was examined by a review of (1) mechanical, electrical and instrument maintenance records, (?) quality assurance document records, (3) equipment surveillance records, (4) Control Operator's and Shift Foremans logs and (5) discussion with maintenance and operations personnel. Haintenance activities were examined in each of the following areas as indicated.

| |
| : a. Facilit S ecifications The requirements for the location and installation of fire barriers and compartment boundary seals for safety related cables including the application of fire retardant coatings for safety related cab!es were described in the FSAR Section 8.2.2.10, "Evaluation of the Physical Layout of Electrical Distribution System Equipment," and, in engineering drawings, and construction specifications. Through discussions with licensee representatives and an examination of the above documents, it was determined that the following requirements were imposed:
| |
| (1) Fire stops were installed at all locations where cable trays passed through a compartment boundary as indicated on Bechtel Drawing No. 734, "Conduit and Tray Arrangement Plan."
| |
| (2) llhere conduits carrying Class I instrumentation cables were installed parallel to and above power cable trays, the conduits were >>rapped with one inch thick insulation thermobestos f'r protection.
| |
| | |
| (3) Haysite polyester board fire barriers were installed between the crossovers o=. cable trays carrying different channels.
| |
| (4) Fire barriers were installed where cable trays or conduits penetrated electrical panels.
| |
| t (5) Bechtel Drawing Ho. E-783, Pevision 3, specified that fire barriers were to consist of (1) 1/4 inch polyester board f/ETR-FR-C from the Haysite Division of the Synthane-Taylor Corporation; (2) Kaowool - Bulk A high purity froml Babcock 8 Wilcox; and (3) Flamemastic 71A - sprayable from Dyna-Therm Corporation. I lI (6) The Haysite polyester board was sized to maintain a minimum of three inches and a maximum of six inch overlap of the cable tray penetration in the compartment boundary..
| |
| (7) The Haysite polyester board was to be cut to fit around the tray and cable with the remaining voids packed with Kaowool.
| |
| (8) Flamemastic 71A was applied to fill the seams between the Haysite, polyester board, seal the edges of the polyester board to the mounting ml.edium, and cover all Kaowool. and exposed cables to a distance of 12 inches from the fire stop. The Flamemastic 71A coating was a minimum of 1/8 inches thick.
| |
| : b. Fire Barrier Ins ec.ions and Tests Inspections of the initial installation of the fire barriers
| |
| 'ere performed by Bechtel inspectovs using Bechtel guality Control Instruction Ho. 206, "Installation Inspection of Cable Trays," The results of theso inspections were documented on Construction Ins'pection Data Reports (CIOR). Record copies of the following CIOR's were examined by the inspector and found to document a completed inspection program of initial fire barrier installation.
| |
| (1) CIDR - Installation of Five Barriers for Cable and-Conduit Penetration of Electrical Panels and Cabinets.
| |
| Inspection performed July-August 1974, (2) CIDR - Installation of Fire Barriers for >lail Penetvations and Tray Separat.'on.
| |
| Inspection performed t1ay through October 1974.
| |
| | |
| (3) CIDR - Ins&llation of Fire Barriers for Cable and Conduit Crossover Separation.
| |
| .Inspection performed July through October 1974.
| |
| Tests of fire barrier adequacy were performed by Bechtel and St<UD personnel at the Rancho Seco site on April 4-5, 1974.
| |
| Three separate tests were conducted in a test stand with various types of cables secured in six inch vertical cable trays. Fire barriers using 1/4 inch Haysite polyester board., Yaowool and Flamemastic 71A were installed on ~he cable trays. Flame temperatures of approximately 1900 F. were applied from a 10 inch ribbon burner at a 30 degree angle from the vertical to the underside of the fire barrier. The flame was applied for 30 minutes in two tests and for one hour in the last test. The test results concluded tha. the fire barrier limits the amount of heat transmitted from the fire on one side to cables on the other side and prevents cables which have been ignited from propagating the flames past the fire barrier. The fire barriers remained intact during all tests conducted, Maintenance and Hodification The maintenance and modification of fire barriers as a result of recent cable changes have remained under the supervision of Bechtel. The procedu "es and specifications including the inspection documentation methods were the sake as those used during initial installation. The licensee's response to IE Bulletin Ho.
| |
| 74-04A indicated that their policies and procedures for maintenance and modification control will be reviewed and changes thereto will be implemented to provide Si1UD with the equivalent requirements currently incorporated in the Bechtel procedures.
| |
| Through discussions with licensee .arid Bechtel representatives and an examination of applicable documents, 26 fire barriers were found to have required , e<<~ork as a result oi cable removal or addition. A review of the records verified that the specifica-tions and inspection requirements had been met for the fire barrier reworl; performed by Bechtel.

| The specifications require the barriers to be constructed of asbestos type sheet material with a Dyna-Therm Flamemastic 71A coating applied three inches above and six inches below the barrier on vertical trays. The spaces between cables at the barrier were to be sealed with Flamemastic 71A i~iastic.
| |
| Attached to the report is a Technical Bulletin by Dyna-Therm Corporation that enumerates the properties of Flamemastic 71A.
| |
| Examination of Fire Barriers A tour of the facility, including the interior of the containment vessel, was conducted to examine the location and installation of fire barriers and the utilization of fire retarding coating (Flame-mastic 71A) for safety related cables. As a general rule, the licensee had adhered to the construction specifications for fire barriers. However, the following deviations were identified.
| |
| | |
| 0,'
| |
| ai Smoke detectors in the cheu:-feed and lube oil area have been shielded from cabling and lube oil filters'y blast shielding installed for protection from pipe whip during the recent refueling outage.
| |
| The fire barrier between the 4 kv cable spread room and the chem-feed and" lube oil area consisted only of galvanized sheet through which the cable trays pass, without an air stop or use of fire retardant material on the cabling. This was also the case in the other 4 kv switchgear room.
| |
| Co Pire barriers had not been installed on vertical cable trays 60V60.and 60V61 in the 4 kv cable spread room as required by construction specification.
| |
| : 5. Maintenance and Modification Procedures Maintenance and modification procedures do not specifically require adherence to the construction procedures for fire barriers. General policy dictates that systems disturbed by these activities be returned to their original state. The construction engineer for the pipe whip modification stated that only one of the cables that pass through a fire barrier was disturbed. In this instance, the sealant was still malleable and was re-formed around the cable after it was replaced. The administrative, procedures will be strengthened in this area, according to the licensee.
| |
| : 6. Status of Licensee's Review of IE Bulletins 7S-04 and 04A The licensee has examined the subject bulletins and determined that the only action required will be to expand existing administrative and maintenance procedures to emphasize salient points of the bulletins. This will be accomplished within 30 days.

| |
| : 1. Maintenance Sco e of Ins ection Maintenance activities on safety related systems and components were selectively reviewed to verify that maintenance activities were conducted in accordance with approved procedures, regulatory guides and industry standards and in conformance with'echnical Specification (TS) requirements.
| |
| The inspector selected for review two maintenance activities from each of nine major system areas. The records of these activities were reviewed in detail to verify that:
| |
| (1) the limiting conditions for operation were met while the component or system subject to the maintenance was removed from service (2) administrative approvals required by the licensee's admin-istrative procedures were obtained prior to initiating the work yC (continued).
| |
| | |
| (3) the maintenance activities were accomplished using approved procedures (4) the maintenance activities were inspected in accordance with the requirements of the licensee's Quality Assurance Plans (QAP)
| |
| (5) the components or systems affected by the maintenance were functionally tested prior to their return to an operating status (6) the quality control. records required by the licensee's administrative procedures and QAP's for each maintenance activity had been prepared and was retained in accordance with the TS
| |
| : b. Re ortin of Haintenance Activities Xn preparing for this inspection effort, the inspector reviewed the licensee's Semiannual Report (dated January 1975) for the period July 1 through December 31, 19?4. The inspector had planned to select the maintenance activities for review from those listed in the above report. The inspector found that contrary to the .requirements of Technical Specification AC 7.6(c) the above semxannua rcport "'d not co"..'tain the required detailed information on sarety related maintenance activities.
| |
| : c. Plant Trouble Re orts Since the, details of safety related maintenance activities were not available in the semiannual report, the inspector selected many of the maintenance activities he would review from the Plant Trouble Reports (PTR) at the site.. PTR's provide a mechanism by which licensee's personnel can inform management of an equipment or system problem. The PTR can also be used to document the corrective maintenance which was taken and the subsequent inspection and functional testing performed.
| |
| The inspector reviewed all completed PTR's from August 1974 through April 1975 for the following systems:
| |
| ~Sstem No. S stem Title ll '2 Reactor Vessel and Internal Components Control Rods and Drives 18 Fuel 21 Primary Coolant System 22 Secondary Coolant System 23 Helium Purification System 92 Electrical
| |
| '93 Controls and Instrumentation (continued)
| |
| | |
| 0 During the review of the PTR's, the inspector found that on October 18, 1974 .a PTR (10-220) was initiated to report a trip of the lA and lB engines to diesel generator 1A. The PTR indicated that the engines had tripped after approximately fifteen (15) minutes of operation due to high water tempera-ture. Further investigation into this incident disclosed that both engines had been given a quarterly inspection during the period October 14 through 16, 1974. The inspector reviewed the completed check-off lists for both engines and noted that the engines had been functionally tested after the inspection. The maintenance work report was completed and signed by the operator conducting the test on October 16, 1974.
| |
| The operating logs on October 17, 1974 indicated that the clearance had been'emoved from the engines and an entry was made indicating that the 1A diesel generator was operable
| |
| . and in standby. The fact that the 1A diesel generator had been declared operable and subsequently failed constitutes an abnormal occurrence as defined by Technical Specification (TS) 2.1(f). Contrary to the requirements of TS AC 7.6 (Non-Routine Reports) this abnoxmal occurxence was not reported to the NRC Regional Office, and the additional actions required by TS 7.3 in the event of an abnormal occurrence were not taken.
| |
| The inspector also found that on December 24, 1974 a PTR (17-368) was init. ated which xeportcd thc failure of YalYe na PlY 0 J-8 to op " cu to a 8 tuck so 1 euviu ~ This valve isolates the bearing water accumulator tank from its circulator after the brake and seal have been set. The licensee is reviewing the reportability of this item as an unusual event in accordance with TS AC 7.6.
| |
| S
| |
| : d. Results of Maintenance Activit Review The maintenance activities which wex'e reviewed during this inspection and the results of the review are shown in Table I.
| |
| These activities were selected fxom the Semiannual Report of July 1 December 31, 1974 and from the plant trouble reports which were reviewed at the site. This review disclosed several items of noncompliance with NRC requirements and conditions of the Technical Specification. The following items of noncom-pliance were found during this review:
| |
| (1} Criterion V of Appendix B to 10 CFR SO requires, in part, that: "Activities affecting quality shall be prescribed by documented instructions, procedures, .... and shall be accomplished in accordance with these instructions, procedu~
| |
| Fort St. Vrain Administrative Procedure ADN-12 (khintenance and Repair Procedures), Section 2.1 and 2.2, establishes the requirements for the preparation and (continued)
| |
| | |
| 0 approval of maintenance procedures. Thi procedure also establishes the mechanism for providing administrative approval to initiate maintenance activities. Contrary to the above requirements, administrative approval to initiate the work had not been given on thirteen (13) of the eighteen (18) maintenance activities reviewed (Table I).
| |
| Technical Specification AC 7.5(b) and administrative procedure ADM-12 requires that procedures shall be developed and approved prior to implementing safety related maintenance. Seventeen (17) of the eighteen activities reviewed were safety related and (18)'aintenance thus required, written procedures. Contrary to the above requirements, thirteen (13) of the seventeen (17) activities had been 'completed without an approved procedure.
| |
| Fort St. Vrain Quality Assurance Plan QAP-1200 (Mainte-nance or Repair of Nuclear Class'I Systems) and Quality Assurance Instruction QAI-11 (Delegation of Specific Responsibilities) establish specific xequirements for the inspection of safety related maintenance activities by an individual other than those,who performed the mainte nance activity. Contraxy to Criterion XVII of Appendix B to 10 CFR 50, documentation did not exist to vexib~
| |
| performance of the required inspection fo" thirteen (13}
| |
| of the eighteen (18) maintenance activities reviewed.
| |
| Licensee representatives interviewed stated that mainte-nance activities are inspected by the foreman or a senior technician, but these inspections are not always documented Fort St. Vrain Administrative Procedure ADM-12 and Quality Assurance Plan QAP-1200 establish requirements for post maintenance tests or operations prior to returning a component or system to service. QAP-1200 also establishes the requirement for documenting these tests. Contrary to Criterion XI of Appendix B to. 10 CFR 50, and the above procedural requirements, no records exist to verify that six (6) of the eighteen (18) maintenance activities reviewed (Table I) had been functionally tested prior to returning the system/component to normal service. Licensee representatives claimed that the'functional tests were conducted, but no records exist to verify the test performed.
| |
| Section 7.0 of Quality Assurance Plan QAP-1200 establishes the requirements for the QA reports and records to be maintained for safety related maintenance activities'.
| |
| TS AC 7.4(b)(8) further.r- requires that the records of maintenance activities be retained for the life *'rinciple (continued)
| |
| | |
| of the plant. Contrary to 10 CFR 50, Appendix B, Criterion V and the above requirements, all of the required QA records had not been prepared for any of the eighteen (18) maintenance activities reviewed.
| |
| : e. ualit Assurance As past of this inspection effort, the inspector interviewed members of the licensee's QA Department to determine the extent of the QA 'involvement in maintenance activities.
| |
| Quality Assurance Plan QAP-1200, Section 6.0, requires assurance inspection procedures shall be prepared to that'uality cover routine, non-routine and special maintenance activities.
| |
| The inspector found that contrary to these requirements and those of 10 CFR 50, Appendix B, Criterion V, no quality assurance inspection procedures had been prepared as of the dates of this inspection.
| |
| During this QA review, the inspector also found that in Hay 1974 the QA Department conducted two audits of the licensee's maintenance in accordance with Quality Assurance Audit Proce-dures QAAP-1201 and QAAP 1203. The results of the audits were reported to the licensee management, but as of .the dates oz this inspection management had not responded.to the. audit reports and correct've action on the deficiencies no"cd ."."-" not "" "..
| |
| ccmplc"d. A QA Department representative stated that several informal memorandums had been sent to management reminding them of the fact that no action had been taken on the audits.
| |
| Criterion XVI to Appendix B of 10 CFR 50 requires tha" measures shall be established to assure that conditiions adverse to quality are promptly identified and corrected. The failure to respond and correct the deficiencies noted in the above audit reports is contrary to the above Appendix B requirements.
| |
| Fire Protection
| |
| : a. Area of Xns ection This. inspection was conducted to determine compliance with 10 CFR 50, Appendix B, Criterion V with respect to fire protection for electrical equipment. This inspection included:
| |
| Review of facility construction specifications to determine that requirements in conformance with the FSAR, Appendix C.3 (which delineates fire protection requirements in accordance with 10 CFR 50, Appendix A, Criterion 3).
| |

| |
| (5) Other fire protection requirements of the FSAR,, Appendix C and Question 7.4, Amendment 19, concerning cable separation.
| |
| : b. Ins ection Findin Review of Construction S ecification Re uirements The inspector found that the Sargent and Lundy Specification 1"N-2 (Issue A, dated January 18, 1969) for Electrical Installation Work, Part 2, and associated construction detail drawings do delineate fire stop requirements and application of fare retardant coatings; however, fare s tops on vertical cable tray runs between floors had not been specified. The FSAR, Appendix C, states that, "Adequate fire stops are used with all major cableways between floors on vertical runs."
| |
| This item was identified as an item of noncompliance at the exit meeting.
| |
| (2) Review of Maintenance and Modification Procedures Class I system changes processed through PSC Engineering Department are reviewed in accordance with ENG-1 for separation and segregation.
| |
| The inspector could find no maintenance or modification requirements with respect to maintaining fire barriers, compartment boundary seals, or application of fire retardant coatings. This item will be followed up during the review of the licensee's reply to IE Bulletin 75-04A.
| |
| (3) Ins ection of Cables and Vital Areas Sargent and Lundy Specification 1-N-2 (Issue A, dated January 18, 1969), Supplement 1 (concerning cable separation), and associated detail construction drawings were used in determining the licensee's conformance with 10 CFR 50, Appendix A, General Design Criterion 3, Fire .
| |
| Protection. The FSAR, Appendix C.3, delineates the licensee's commitment to conform to Criterion 3 of Appendix A. The cable separation requirements identified in (continued)
| |
| | |
| 0 Appendix C.3 of the FSAR are further defined in Question 7'.4 of the FSAR, Amendmcnt 19.
| |
| (a) Vertical Cable Txa Risers Reactor Buildin The detail construction drawings (such as E-43, Revision J; E-41, Revision B; and E-42, Revision H, "Cable Trays Reactor Building Sec's and Det's")
| |
| specify that fixe stops axe to be installed in the Reactor Building vertical risers in accordance with Sargent and Lundy Standard STD-EA-176. STD-EA-176 specifies that a fire stop will consist of two feet of insulating material (Owens-Corning Fiberglas, Corp., Thermal Insulating Wool or equivalent) with Plamemastic 71 or other suitable material to hold the insulating material in place.
| |
| The inspector did not find that fire stops had been
| |
| .installed in any of the vertical cable tray risers in the Reactor Building. This item was identified at the exit meeting as an item of noncompliance. The licensee is initiating corxective action.
| |
| (b) Reactor Buildin to Auxiliar Buildin Cable Seals Detail construct'on dxawin E-140, Revision F Gpecif ies tha t tLansi t sleeves, as manufactured by Nelson Electric Division of Sola Basic Industries, are to be installed in multiple clusters at the point the cables pass through the Reactor Building wall into the Auxiliary Building.
| |
| The inspector found that sleeves are installed as required.
| |
| (c) Horizontal Cable Tra s I
| |
| Detail construction drawing E-54, Revision K, specifies three-eighth inch Harinite Sheets are to be cut to fit after cables are installed and placed on each side of the wall. The void on each side of the tray and between the sheets are to be packed with an inorganic fiber material.
| |
| The inspector found no horizontal tray fire stops installed in accordance with drawing E-54. The "as installed" fire stops varied from tray to tray (Harinite sheets on each side of the wall, Harinite sheets on one side, and in at least two cases, no Naxinite sheets). The inspector found no cases in (continued)
| |
| | |
| which the inorganic fiber material had been installed. The inspector stated at the exit meet-ing that this item was considered an item of non-compliance. The licensee is initiating action to install the fire stops as required by construction specification 1-N-2.
| |
| Cable Tra Risers
| |
| 'd).'ertical The inspector could find no construction specification requirements for vertical cable tray risers through floors of vital rooms such as the cable spreading room.

| (5) Other Fire Protection Re uirements
| |
| *(a) Se aration of Nonessential Cable Associ'ated with Test
| |
| ~Pro ram The FSAR, Appendix C.3 (in response to 10 CFR 50, Appendix A, Criterion 3) states that "Redundant power, control, or instrumentation circuits are physically separated or protected to prevent damage, as a result of fire, ..." The FSAR, Question 7.4 states in part.
| |
| with respect to essential cables in the cable spread-room, "... the cables are routed from the tray system to the control boards with a minimum separation of six inches between redundant circuits. Where this physical separation cannot be maintained, due to limited space,.
| |
| one cable is enclosed in asbestos zipper tubing to maintain segregation of the redundant circuits."
| |
| (continued) I
| |
| | |
| Question 7.4 states further that with respects to nonessential circuits, "Nonessential circuits are routed in the same trays as essential circuits; and follow the separation criteria for essential cables in that tray or section."
| |
| The inspector, during a tour of the cable spreading room, noted several areas where temporary cable had been installed for the test program that did not meet the separation criteria stated above. Asanexample, in one area there were test cables which crossed within less than six inches of permanent redundant cables terminating in the Loop 1 and Loop 2 Coolant system instrument panels. Asbestos zipper tubing had not been installed.
| |
| The licensee concurred in the inspector's finding and stated at the exit meeting that separation in the cable spreading room was being reviewed. Some zipper tub-ing was installed prior to the completion of the inspection and additional zipper tubing was being ordered.

Further, the FSAR, Appendix C.3 (in response to Criterion 3 of Appendix A) states in part, "The facility is constructed making maximum practical use of noncombustible and fire resistant material."
| |
| The inspector, during a tour of the cable spreading room, noted approximately eight pieces of wooden plywood cabinets, tables, and stands associated with test equip-ment. Also, two wooden desks and a drawing/print file were noted. The inspector stated at the exit meeting that the introduction of flammable material in the cable spreading room was not consistent with 10 CFR 50, Appendix A. or the FSAR, Appendix C.
| |
| Batter Room Door The FSAR, Appendix C (in response to 10 CFR 50,<<
| |
| Appendix A}, states in part that, "h'here the possibility of an explosion exists in redundant equipment, ..., suit-able separation and/or missile shielding is provided to prevent an explosion in one unit from damaging the other".

| |
| (3) Review of Surveillance Test Procedures The inspector found that the Plant Operations Review Committee (PORC) minutes do not indicate PORC review of the initially issued Surveillance Test Procedures, from time of licensing until 12/10/74, as required by TS AC 7.5.d, which states in part, "Procedures prepared for a) and c)(1) above shall be reviewed by the Plant Operations and Review Committee." The licensee did demonstrate that (during the December 10, 1974 PORC meeting i'Pi5) review of the surveil-lance test procedures was conducted and documented. The licensee did state that prior review of surveillance test procedure by the PORC (as a body) had not occurred; but, the licensee did demonstrate that the review and approval signatures on. each surveillance test procedure are within one of the required quorum (TS AC 7.1.2;c three members plus the chairman or designated alternate).
| |
| (continued)
| |
| | |
| This item is identified as an item of noncompliance for which no response is required based on the subsequent PORC review of the Surveillance Test Procedures.
| |
| : 4. Audit Records (Reference IE:IV Inspection Report 50-267/75-02)
| |
| The Technical Specification (TS) AC 7.1.3.d.4 states that the Nuclear Facility Safety Committee responsibilities include, "Conduct audits no less than semiannually of facility operators for compliance with internal rules, procedures, regulations, and license require-ments, including Technical Specifications", and TS AC 7.1.3.d.7 states that, "Follow-up action, including re-audit of deficient areas, shall be taken as required."
| |
| Contrary to the above requirements, the inspector did not find that audit schedules have been established, or audits conducted by the NFSC as required.
| |
| The inspectox did discuss with the licensee the interfacing of the NFSC and the licensee's QA Organization as i.t relates to the performance of the TS prescribed audits.
| |
| This item was identified at exit meeting as an item of noncompliance.

| IE Inspection Report 50-267/75-03)
| |
| Technical Specification (TS) AC 7.1.3.d.l2 states that it is the responsibility of the NFSC to, "Review proposed tests and experiments and. their results."
| |
| Contrary to the above requirement, the inspector was informed by the licensee personnel that the NFSC reviews only those tests ox experiments considered to be safety significant. The licensee has stated his intent to amend this TS requirement, but a proposed change has not been submitted.
| |
| The inspector identified Gulf Atomic RT 320 (dated 12/20/74) which requested a test to investigate the count rate response af the start-up channels with the detectors wrapped with Cadium, as an example.
| |
| This test, although it involved safety related instruments, was
| |
| ', determined by the PORC to be nonsafety si'gnificant and therefore, not subject to NFSC review prior to conducting the test.
| |
| The inspector stated, at the exit meeting, that although it was licensee's intent to submit a proposed change, this item was con-sidered an item of noncompliance with the TS.

The licensee stated that possible interplay between the two primary coolant loops is being investigated.
| |
| (2) Purification S stem Trouble has been experienced in the secondary side of the gas to gas heat exchanges with condensation of moisture.
| |
| The source of moisture condensation has been traced to a pexiod of time concurrent with the moisture ingress into the PCRV. Possible modifications to this system are being reviewed from the aspect of being able to decrease the time required to dry the system out.

Cable Fire Prevention a.* Licensee's Res >onse to IE Bulletins 75-04 and 75-04A On March 25, 1975 the NRC Office of Inspection and Enforcement (IE) issued IE Bulletin (IEB) iNo. 75-04, entitled "CABLE FIRE AT BROWNS FFRRY NUCLEAR POWER STATIOii". This bulletin provided licensees with preliminary information concerning a fire which occurred on March 22, 1975 at the Tennessee Valley Authority's Browns Feery site. The bulletin also requested the following actions of selected licensees:
| |
| I'continued)
| |
| | |
| II
| |
| : 1. "Review your overall procedures and system for controlling construction activities that interface with reactor operating activities, with particular attention to the installation and
| |
| 'esting of seals for electrical cables between compartments of the reactor building, e.g., control room to cable spread-ing room.
| |
| 2~ "Review the design of floor and wall penetration seals, with particular attention to the flammability of materials.
| |
| 3~ "Evaluate your procedures for the control of ignition sources which may be used for leak testing or other purposes in areas containing flammable materials.
| |
| : 4. "Report to this office, in writing within 20 days of the date of this Bulletin, the results of your reviews or evaluations regarding items 1 through 3 above."
| |
| Cooper Nuclear was not one of the selected licensees requested to
| |
| .take action under IEB 75-04 at the time it was first issued.
| |
| On April 3, 1975 the Office of Xnspection and Enforcement issued XEB 75-04A (same title as that of 75-04) which provided additional information concerning the Browns Ferry fire. XEB 75-04A required all licensees to carry out the actions requested in XEB 75-04 and outlined additional actions to be taken by licensees as follows:
| |
| : l. "Because the occurrence appears to have resulted from modifications being made to an operating unit, all power reactors with operating licenses should address the actions requested in Bulletin 75-04 as well as the actions described below.
| |
| 2~ "Review your policies and procedures relating to construction or maintenance and modification work to assure that activities which might affect the safety of a unit in operation, including the ability to shut down and cool the unit are properly controlled.

| by'Bulletin 75-04 may be incorporated with the initial response to this Bulletin."
| |
| The licensee's initial response 1/ to the above bulletins was submitted within the specified time period. The licensee's response letter presented, their position and proposed action for each of the items of action outlined in the two bulletins.
| |
| During this inspection, the inspector .reviewed the actions taken by the licensee and discussed with several licensee representatives the positions taken by the licensee on those items for which no specific action is indicated. The licensee's response to and their actions taken for each of the items of action requested in the subject bulletins are summarized below.
| |
| In response to Item 1 of the action requested of licensees in IEB 75-04, the licensee stated that they had reviewed their procedures for controlling construction activities and believed them to be adequate. The inspector found that the procedure which, the licensee has for controlling construction activities is Administrative Procedure 1.7'entitled, "Station Maintenance". The primary construction activities currently underway at the Cooper Station are performed by employees of Burns and Roe, Inc. who are constructing the Augmented, Radwaste Facility which is adjacent to the, existing Radwaste Building.
| |
| By letter dated April 18, 1975, NPPD (K. Meyer) advised Burns and Roe (J. Bowles) of their responsibility to work within the procedural requirements of Procedure 1.7. This fact was acknowledged by letter dated April 25, 1975 from E. Kuchera (Burns and Roe) to K. Meyer.
| |
| ~ s Although Procedure 1.7 is acceptable for controlling construction activities in general, the procedure does not.specifically address
| |
| -the installation and testing of seals for electrical cables between compartments of the reactor building.
| |
| This fact was discussed with licensee representatives who stated that attention to the installation (or reinstallation) and testing of seals for electrical cables would be assured by the engineering, quality assurance, and operations department reviews of maintenance activities required under Procedure 1.7. They felt that this was an unwritten policy for personnel in the above departments and that specific written guidance was not necessary. The lack of specific guidance in this area was identified as an unresolved item..
| |
| In response to Item 2 of IEB 75-04, the licensee indicated that high and low density cellular concre'te had been used to fill penetration openings and urethane foam painted with fire retardant intrumescent paint had been used to fill smaller holes and the ends of conduit.
| |
| This fact was generally corroborated by the inspector. Details of the inspection of penetration seals is contained in part b of this section.

| |
| 'The licensee's response to Xtem 3 of IEB 75-04 indicated that they had evaluated their procedures for the contxol of ignition sources.
| |
| They stated that they do not use an open flame or an ignition source for leak testing and that their procedure entitled. "Hazardous Haterial Control" will reduce the probability of fires in areas containing flammable materials. This procedure was reviewed in detail during this Inspection. The results of this review are discussed under Xtem 3.b to IEB 75-04A. The fact that the licensee does not use an open flame or an ignition source for leak testing is an unwritten policy. The licensee representatives interviewed did not feel that a wxitten policy .or procedure was necessary to prohibit the use of open flames or ignition sources in 1'eak testing. They felt that the supervisors who review maintenance and modification procedures were aware of this policy and would prevent the use of open flames or sources. This item was identified as an unresolved item. 'gnition In responding to Xtem 2 of the action section of IEB 75-04A, the licen-see stated that policies and proceduxes relating to construction, maintenance, and modification work have been reviewed and are con-sidered adequate to assure that safety related activities are properly controlled. The licensee noted that Administrative Procedure 1.7 (Station lfaintenance) and 1.13 (Station Design Changes) provide control of construction/maintenance and modification activities respectively. The inspector reviewed these procedures and found that they were acceptable for the general control of these activities, but no specific guidance was given in either procedure concerning a policy of deferring the above activities (except for emergency maintenance) unitl a shutdown period. The 1falfunction/4'oxk Request (KJR), established by Procedure 1.7 and used for all maintenance activities, does provide for the designation of a maintenance priority, but the priorities which may be selected to not include a "defer until shutdo~m" category. Licensee representatives indicated .
| |
| that it is Cooper Station's unwritten policy to defer (when possible) safety related maintenance until a shutdown period. They did not believe that a written policy or procedure to defer these activities was necessary. The absence of a written policy in this area was identified as an unresolved item.
| |
| In the licensee's response to Item 3.a of XEB 75-04A, they stated that, "The plant policies and procedures for reviewing the degree of safety significance of affected and nearby cabling and piping during con-struction, modification, or maintenance work are now considered adequate.
| |
| By the implementation of bib'R's and/or minor design change procedures for all required work, safe practices can be assured."
| |
| The procedures referred to in this response are Administrative Proce dures 1.7 and 1.13. As noted in the above evaluations, these proce-dures provide acceptable guidance for the review and control of maintenance/construction and modification activities, but there exists no specific written guidance for the supervisory or other individuals (continued)
| |
| | |
| who review these activities to assure that the review includes the degree of s'afety significance of affected and nearby cabling and piping. The licensee representatives'nterviewed did not believe that written guidance was necessary to assure this type of review.
| |
| They were of the belief that all of the reviewers of maintenance and modification activities were cognizant of the potential hazards to cabling and piping during such activities and would consider these potential hazards during their review. The absence of specific written guidance in this area was identified as an unresolved item.
| |
| In responding to Item 3.b of IEB 75-04A, the licensee ..tated that "Procedure 1.6.8, Hazardous Material Control, provides for the safe use and storage of all combustible materials at CNS."'he inspector reviewed procedure 1.6;8 and found that it did provide for the control of the following combustible materials:
| |
| (1) Gaseous hydrogen (2) - Acetylene (3) Fuel gas (4) I'uel oil (5)'irconium turnings, borings, filings, chips or dust The inspector noted that the above procedure did not include controls for such additional combustible materials as:
| |
| (1) Lubricating oils
| |
| '(2) Paint (3) Wood and paper. products (4) Rags Licensee representatives stated that these materials should also be controlled under Procedure 1;6.8. They indicated that Procedure 1.6.8 would be modified to provide controls for the above listed items.
| |
| This item is identified as an unresolved item until Procedure 1.6.8 is modified.
| |
| In the licensee's response to Item 3;c of IEB 75-04A he stated that, "Procedures and policies concerning the use and control of equipment that might be an ignition source have been reviewed and are considered adequate."
| |
| The procedures which control cutting (torch) and welding operations are Administrative Procedures 1.7.3 (Cutting and Welding Permits) and 1.17 (Administrative Procedure for.'Special Process Control). The (continued)
| |
| | |
| F inspector reviewed these procedures and found them acceptable for the control of cutting and welding operations. As noted in the previous evaluations, the licensee has no written policy or procedure
| |
| 'to control the use of open flames or other ignition sources for leak testing.
| |
| Xn responding to Item 3.d of IEB 75-04A, the licensee indicated that personnel knowledgeable of plant arrangement and operations would be assigned'to monitor unattended areas adjacent to work only 'when there is a "probability of concern". The licensee's response stated that, "He believe that routine plant patrols adequately cover many of these areas." The inspector found t.hat the above policy is unwritten as is the definition of the term "probability of concern". Licensee representatives interviewed in this area felt that a written policy was not necessary because the requirement for a full time monitor would be identified during the review of maintenance or modification pro-cedures. This item was identified as an unresolved item.
| |
| The .licensee's response to Item 3.e of IEB 75-04A stated that, "Pro-cedure 2.2.4 provides for instruction on the use of the installed and portable communication equipment available at the plant. Sufficient equipment., both protable and installed, are available to provide monitoring personnel with prompt communications with the Control Room operating staff as required." The inspector reviewed Procedure 2.2.4 (Communications System) and the communications installation at the facility and found no discrepancies.
| |
| In response to Item 3.f of IEB 75-04A, the licensee stated that they had reviewed their fire protection system and consider it adequate to safeguard all areas of the plant. In Amendment No. 15 to the FSAR, the licensee responded to FSAR Question No. 7.4 with a detailed description of the fire detection and protection installations in the areas where safety related cables are installed. The fire detection and protection installations were to include:
| |
| (1) A dry pipe and pre-action sprinkler system in the Electrical Cable Spreading Room.
| |
| (2) A dry pipe and pre-action sprinkler system in the Reactor Building area above the Hotor Generator Sets.
| |
| (3) A wet pipe automatic sprinkler system 'above the Hotor Generator Set Oil Pumps and Hotors.
| |
| (4) An automatic C02 system for each of the dieslc generator rooms.
| |
| (5) Smoke detectors in the following critical areas.
| |
| (a) Computer room ceiling.

| (c) D.C. switchgear room ceiling.
| |
| (d) Battery room ceiling.
| |
| ~
| |
| (e) Peactor pxotection system MG set room ceiling.
| |
| The inspector toured the above areas and verified the installation of the above fire detection and protection equipment. The inspector also noted an ample number of wall mounted C02 hand ex< inguishexs located throughout the above areas.. The inspector also noted that smoke detectors had been installed in the reactor control room. Ho discrepancies were noted in this area.
| |
| ~ In responding to Item 3.g of IEB 75-04A, the licensee noted that, "Fire fighting procedure 5.4 provides for instruction to personnel
| |
| 'oncerning the various types of fires and the required action of the plant personnel in response tq a fire. It is recognized that a fire, even. one involving electrical equipment may, if of sufficient intensity, require water as the ultimate suppression medium." Procedure 5.4 consists of a general Eire procedure (5.4.1) and twenty-five (25) special E'ire procedures which provide guidance in fighting Eixes in many different areas throughout the plant. The inspector noted, however, that none of the procedures reviewed addressed the above stated policy that an electrical fire of sufficient intensity may require water as 'the ultimate suppression medium. In fact, a number of the'proceduxes contained a statement to "avoid using water on electrical fires." The inspector discussed with licensee representatives this apparent conflict from their stated position (above IEB response) on the use of water on electrical fixes. The licensee representatives stated that they would review this item further. This item was
| |
| -identified as an unresolved item.
| |
| In response to Item 4 of IEB 75-04A, the licensee stated that pro-cedure 5.2.1 (Shutdown from Outside Control Room) was being revised to include local operation of core standby cooling systems and a new procedure 5.2.10 was being written to provide for flooding of the reactor core with service water. These procedure changes had not been completed as of the date of this inspection. Thisitem remains open.
| |
| : b. Fire Barriers The primary objectives of this inspection were to'.
| |
| (1) Examine the construction specifications of the facility to determine what requirements had been imposed'or.:
| |
| (a) Location and installation of fire barriers and compartment
| |
| ( boundary seals for safety related cables.
| |

| |
| | |
| 0 s V'
| |
| | |
| <<15-(b) Application and the extent of application of fire
| |
| .. retardant coating for safety related cables.
| |
| (2) Examine maintenance and modification procedures to determine whether the requirements of (1), (a) and (b) above are invoked on a continuing basis.
| |
| (3) Visually examine the facility to determine the extent of con-formance to the requirements identified above.
| |
| Construction S ecifications on Fire Barriers In Amendment No. 15 to the FSAR the licensee responded to FSAR Question No. 7.4 with the criteria for cable routing in containment, penetration areas, cable spreading rooms, control rooms and other congested or hostile areas. The licensee's response stated that for floor and wall openings in Pire Hazard Zones, "runs of NSSSS and ESS cables are sealed with fire resistant material." The construction specifications which satisfied this commitment are contained in page G-03 of Burns and Roe, Inc.. Specification E.70-3 entitled, "Instru-ments and Control System Installation" and on Sheet 2 of Burns and Roe, Inc.. Drawing No. 3136. Xt was noted that the original spec-ifications called for the use of ceramic fiber, such as Babcock and 7lilcox "YNOVOOL" (or approved equal), packed into the conduit or cable tray penetrations. This specification was subsequently changed to provide the following fire stop installation:
| |
| (1) High density or low density cellular concrete to fill floor
| |
| .and wall penetration openings around conduit and cable tray runs. The high density concrete was specified for use where radiation resistance and strength was. necessary'.
| |
| (2) Small holes and ends of conduit were to be filled with urethane foam. The exposed surfaces of the foam were to be painted with PPG f/42-7 fire retardant intrumescent paint.
| |
| The construction specifications did not call for an application of fire retardant coating on safety related cables. The inspector reviewed, however, the qualification test report for the electrical cables used at the Cooper Nuclear Station. The qualification tests were conducted by the Franklin Institute Research Laboratories and the results reported in Report ifF-C 2927, dated October 1970. The following tests were included in the qualification test program:
| |
| Heat Resistance Test Irradiation and Post Accident Environmental Test Cable Tray Pire Propagation Test Dielectric Test All of the cables tested were found to be acceptable.
| |
| (continued)
| |
| | |
| 0 Maintenance and Modification Procedures Modification and maintenance procedures were reviewed as part of the followup on the licensee's response to IE Bulletins 75-04 and 75-04A.

| The results of this review are detailed in Section l.a of this report. r Visual Examination of Fire Barriers The inspector toured the facility to visually examine and verify the installation of fire barriers in accordance with the construction specifications. The'reas which were covered by this tour included:
| |
| (1) The Reactor Building (at elevation levels 903'-6", 931'-6",
| |
| 958'-3" and 976'-0")
| |
| (2) Auxiliary.Relay Room (elevation 903'-6")
| |
| (3) Reactor Protection System H-G Set Rooms 1A and 1B (elevation
| |
| '. 903'-6")
| |
| (4) Battery Rooms lA and 1B (elevation 903'-6")
| |
| (5) DC Switchgear Rooms lA and 1B (elevation 903'-6")
| |
| (6) Cable Spreading Room (elevation 918'-0")
| |
| (7) Cable Penetration Room (elevation 918'-0")
| |
| (8) Reactor Control Room (elevation 932'-6")
| |
| (9) Computer Room (elevation 932'-6")
| |
| (10) Reactor Drywell (elevation 903'-6" and 9l<2'-6")
| |
| The inspector found that, with the exception of the Reactor Building, all floor and wall penetrations had been sealed with the low density cellular concrete in accordance with the revised construction specifications. The inspector found that in several of the cable tray
| |
| .penetrations between the Cable Spreading Room and the Cable'Penetration Room and the penetrations between the Cable Penetration Room and the Reactor Building small strips (approximately one inch thicl'nd three inches vide) of a urethane foam material remained across the width of the cable tray. The inspector tested the foam material and verified that it was combustible, but the foam had not been painted with a fire retardant paint. The strips of foam .had beei> used to seal the gaps between the cables and the concrete for'ms used while the seals were poured. The. foam strips had not been removed when the forms were disassembled. The foam strips are imbedded in the concrete seals to a depth of loss than one inch.
| |
| (continued)
| |
| ~ ~y.
| |
| | |
| In discu'ssing the foam strips with licensee representatives, the
| |
| 'inspector noted that'the exposed surfaces of the foam strips which are not painted with ire retardant paint is contrary to the FSAR commitment which states that'runs of NSSS and ESS cables are sealed with fire resistant material" and to the revised construction specifi.cations for fire, bazriers which required that all exposed surfaces and urethane foam be painted with PPG !I42-7 fire retardant paint. This item is identified as an item of noncompliance with the requirements of Cziterion V, Appendix B, 10 CFR 50, which states in part that "Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accord-ance with these instructions, procedures or drawings." A licensee representative stated that the foam strips would be zemoved. He said that the foam strips which are most accessible will be removed as soon as possible, but those strips which are not readily accessible will be removed during the next scheduled outage of significant duration.
| |
| During hi.s tour of the Reactor Building, the inspector found that fire barriers had not been installed for several of the cable runs b'etween floor levels of the. building. The inspector pointed out this discrepancy to licensee and Burns and Roe, Inc. representatives and noted that Section C.2.d of the licensee's answer to FSAR Question No. 7.4 states that, "Floor and h'all 0 enin,s runs of NSSSS and ESS cables are sealed with fire resistant material". The inspector also noted that Burns and Roe, Inc. construction specification E.70-3 states (on page 6-S3), "hhen all conduits have been installed, this contractor shall close up the openings throughout the entire plant."
| |
| The inspector stated that the failure to provide fire barriers for all floor openings in the Reactor Building is an apparent deviation from the above FSAR commitment. The licensee and contractor repre-sentatives said that they did not agree with the inspector concerning the identification of these items as a deviation from the FSAR commitment. They noted that those barriers which had been installed in the Reactor Building floor openings were i.n the immediate area of the Recirculating Pump ."fotor Generator (N-G) Set or the lube oil pumps and heat exchangers which service the H-G Sets. The licensee and contractor representatives said that these barriers serve to prevent H-G Set oil spills from running down the'able runs and are not fire stops. They noted that there are numerous pipe chases throughout the Reactor Bui.lding along with the open equipment hatch and elevator shaft which 'would not prevent a fire from propagating between floors. They said that since the other openings would not prohibit the propagation of a fire, fire stops in cable openings would serve no real purpose. On the basis of the above position, the licensee representatives said that they 'did not plan to install addi-tional fire stops in the Reactor Building. The inspector said that he would identi.fy this item as an unresolved item and .refer it to his management for resolution.

| |
| : c. Cable Se aration In the licensee's response to FSAR Question No. 7.4, specific criteria for the separation of safety related cables was outlined to minimize the potenti'al for fire damage to cables of redundant systems/
| |
| components. During his tour of the facility to verify the installation of fire barriers (Section l.b), the inspector also observed the extent of compliance with the cable sepaxation commitments made in the FSAR.
| |
| H The inspector found that in general, the licensee's commitments had been met for:
| |
| (1) Horizontal separation of cable trays.
| |
| (2) Vertical separation of cable trays.
| |
| (3) Vertical separation of conduits.
| |
| (4) Separations within control panels and instrument racks.
| |
| The inspector found six (6) discrepancies in the area of cable separation. The discrepancies are:
| |
| (1) On the northeast end of the Reactor Building a Division I (C-82) and a Division II (C-99) cable tray run vertically from the 931'-6" elevation to the 903'-6" elevation witn a horizontal separation of approximately eight (8) inches. The horizontal separation criteria of the above FSAR commitment has not been met for this cable run by the fact that the inside cover of the
| |
| .Division I tray is not solid metal.
| |
| (2) On the northeast corner of the Reactor Building, near the ceiling of the elevation 903'-6", a Division II cable tray crosses over a Division I cable tray with a vertical separation of less than eighteen (18) inches. The solid metal cover on the bottom of the Divisiop II cable trays was apparently moved during installation exposing a gap of about one inch in width.
| |
| (3) On the east end of the Cable Spreading Room (elevation 918'-0")
| |
| a terminal box (designation unlcnown) contains Division I and Division XI cables which are properly separated within the box.
| |
| The cables coming out of the box, however, are run in cable trays which parallel each other with a horizontal separation of less than six. (6) inches for a length of about two (2) feet. A fire barrier has not been installed between the cable trays in accord-ance with the FSAR separation criteria; (continued)
| |
| | |
| 0 (4) . On the northvest corner of the Cable Spreading Room a Division I cable tray crosses over a Division II cable tray and the-metal cover over the Division II t:ray does not extend to five (5) feet on each side of the cross-over area as required
| |
| . by the FSAR commitment:.
| |
| I (5) In the Auxiliary Relay Room the Division II cable from the Division II relay cabinet are laid in.a cable tray which runs west and then north and exits through the northwest area of the. ceiling. The cable tray is installed in such a manner that it passes within a three (3) feet horizontal separation of the Division I cable tray which collects the cables from the Division I relay cabinet. No fire barrier has been installed between the two cable trays as required by the FSAR commitment.
| |
| (6) Tvo cable trays ring the Reactor Drywell with most of the runs being in the upper position of elevation 903'-6". The cable trays are designated C85 (Division I) and C84 (Division II) and are run with C85 above C84 vith a separat:ion of about one foot.
| |
| In the horizontal runs, a solid metal tray has been installed on
| |
| ~ the top of C84, but: no solid metal tray had been installed on the bottom of'85, as required'y the FSAR separation require-ments. In t: he verEical runs of. the above cable trays the separation is still about one foot:, but: no fire barrier had been insta3.led between t: he cable t:rays which is contxary to the FSAR separation requirements.
| |
| The inspect:or told licensee and contract:or representatives that the above discrepancies vere contrary to the licensee's commitment in the FSAR. The inspector point:ed out the fixst five discrepancies to several licensee and Burns and Roe, Inc. representatives vho acknowl-edged that the discrepancies were contrary to the FSAR commitment.
| |
| The discrepancies in the'dryvell vere pointed out t:o the licensee representative vho accompanied the inspector into the dryvell. The inspector did not det:ermine, if construction specifications exist to satisfy the FSAR cable separation requirements. The above discrepancies imply that either an adequate specification had <<ot been prepared or that the specification had not been followed. In either case the above discrepancies constitute an item of noncompliance vith Criterion V, Appendix 8, 10 CFR 50, which is quoted in part: in Section l.b.
| |
| : 2. 0 eration at Reduced Power On April 26, 1975 the NRC Office of Nuclear Reactor Regulation issued an Order for the modification of the Cooper Nuclear Station License (No. DPR-46) to limit the maximum core power level and the maximum core flov rate to 50% of design power and design flov rate. The order. was issued on the basis of possible vibration of instrument tubes vhich is suspected by the anoma3.ous readings from a transversing incore probe (TIP).
| |
| (continued)
| |
| | |
| 0 The inspector reviewed the operating records of the facility and verified that core power and core, flow were reduced to 'less than 50% on April 26. Core power. and flow have not'exceeded 50% since April .26. The licensee has informed all operating personnel of the power and flow limitations.
| |
| The licensee has begun a program of obtaining weekly TIP readings from all TXP positions. This program will enable him to monitor the core and detect any recurrent vibration indications. The inspector reviewed the TIP traces taken on Hay 2, 1975 at 48.6% power and 45.4% flow. No discrepancies .were noted.
| |
| .3. Status of Power Ascension Test Pro ram During this inspection, the status of the power ascension test progiam at the 100% plateau was xeviewed in detail. The completed tests (listed below) which had not been previously reviewed by the inspector, were, reviewed to verify that:
| |
| : a. . The test had been conducted at the power level and core flow conditions required by the PSAR.
| |
| : b. The procedure used had been properly approved.
| |
| : c. Indicated "hold" points in the procedure had been signed-off.
| |
| : d. The results of the test conformed to the indicated acceptance criteria.
| |
| e, 'he test results had been reviewed by the Cooper staff and by the Staxtup Test Committee.
| |
| Deviations from the indicated acceptance criteria had been resolved in the review process.
| |
| The inspector also reviewed Staxtup Report - Supplement No. XI, dated April 29, 1975, 'to verify that the test results reported were consistent with the startup test records. No discrepancies were found.
| |
| The following tests have been completed through the final review of the Startup Test Committee and have been accurately reported in the Startup Report:
| |
| I Test No ~ Test Title STX-9 Mater Level Heasurement STX-13 Process Computer STX-18 Core Power Distribution STI-19 *Core Performance STI-20 Steam Production (continued)

| |
| ,>'<The FSAR required that portions of these tests be run at flow and power conditions which the licensee believed to be unnecessary or undesirable.
| |
| The tests were not conducted under these conditions. The licensee has reviewed these changes to the test program and reported same in Section XII of Startup Report - Supplement II.
| |
| 'he above reviews were conducted during the part of the inspection held on Hay 5-7, 1975. .The inspector noted that Test STI-16 (Selected Process Temperatures) had been completed and reviewed by'he Startup Test Committee, but the test results had not been reported in Startup Report - Supplement II. A licensee representative said that the results of this test would be reported as a revision to Startup Report Supplement IX. The inspector also found that Test STX-24 (Bypass Valves) had not been conducted with natural circulation flow on the 100% load line (Condition 4A) as required by the FSAR program. The licensee representative said that they did not plan to run this test under condition 4A and would justify this test program change in the above revision to Startup Repox't - Supplement XI.
| |
| R>en the inspector returned to complete the inspection on May 16, he was informed by a licensee representative that the revision to Startup Report Supplement IX had been issued on Hay 14, 1975 and was entitled "Startup Test Program, Attachment A to Supplement XI". The inspector reviewed this document and found that the results of Test STX-16 had been accurately reported and that the test program change to eliminate condition 4A from Test STX-24 had been justified. The inspector found no discrepancies with this document.
| |
| The licensee has conducted all of the tests required by the FSAR test program or has justified program- changes in his Startup Reports. All of the test results have been reviewed by the Startup Test Committee (STC)
| |
| . and have been accurately reported in the Startup Reports. Deviations fron> the indicated acceptance criteria have been reviewed and resolved by the STC and have been reported in the Startup Reports. A licensee representative said that they believe the requirements of thc Startup Test Px'ogram have been completed and that the licensee will begin ine'rting the drywell (a., required by TS) after the startup which follows the current outage period. The inspector said that he concurs with the licensee's position on the completion of the Startup Test Program and the requirement to begin drywell inerting when reactor operation resume.

| Followu on IE Bulletin 75-03 C On Harch 14, 1975, the NRC Office of Inspection and Enforcement (IH) issued IE Bulletin (IEB) No. 75-03 entitled "INCORRECT LOWER DISC SPRING AND CLEARANCE DI"KNSION 'IN SERIES 8300 AND 8302 ASCO SOLENOID VALVES". The bulletin advised licensees of recent abnormal occurrences at two power reactors in which safety related solenoid air-pilot valves manufactured by Automatic Switch Company (ASCO) failed to operate properly. The bulletin further described the types of ASCO valves which have failed and the apparent cause for the failures. .Licensees were advised to contact the ASCO valve service department in case of uncertainty.
| |
| The bulletin outlined the following action to be taken by all power reactor licensees with operating license or construction permit:
| |
| l.'Determine if ASCO valves of the types .described above are in use or palnned for use in safety related systems..
| |
| : 2. "Report to this office in writing, within 30 days for facilities with operating license, and within 60 days for facilities with construction permit, the results of your findings with regard to
| |
| ~ Item l.
| |
| : 3. "If solenoid valves of the ty'pes described are in use ox planned for use in safety related systems, include in your written reply the actions you have taken, or plan to take, to prevent failures of the type described above. Your written reply should also include the date when such actions were, or will be, completed."
| |
| The licensee's reply 2/ to IEB 75-03 indicated that they did not have any of the specified series of ASCO solenoid valves in their safety related systems. They did note, however, that four of the ASCO Series 8302-C form U solenoid valves were installed to control fan dampers in the drywell ventilation system and several of the series 8302-C from RU v'alves are in the Augmented Radwaste Building Systems. They further noted 'nstalled
| |
| . that they had been in contact with the manufacturer (ASCO) and planned to follow ASCO's recommendations on the actions taken.
| |
| a During this inspection, the inspector reviewed the corrective actions taken by the licensee relative to the above ASCO valves, The licensee had contacted the ASCO valve service department and had received additional information 3/ on the previous failures of these valves and the actions to take to prevent further failures.
| |
| The ASCO letter also included a detailed list of, the specific catelog numbers for all of the solenoid valves ubject to the type of failure noted in the bulletin. The letter also enclosed a maintenance instruction sheet (ASCO 1&~41 Sheet U-5503) which outlines the procedure to check and adjust the solenoid valves.

| | |
| <<23 The licensee had completed the inspection of the seven (four in drywell ventilation system, and three in radwaste systems) solenoid valves of the types listed in the ASCO letter. This inspection verified that the lower valve disc clearance was in the range of 0.008 to 0.016 inches as required by the ASCO instructions. Two of the valves in the radwaste system have resilient seats. The licensee had ordered the conversion kits that will convert the valves to provide metal-to-metal seating surfaces.
| |
| The licensee anticipated receiving the conversion kits and modifying the valves before Hay 15, 1975. Since these valves are not safety related, no additional followup will be made on the above conversions. This item is closed.
| |
| : 5. Abnormal Occurrence (AO) Re ort Follow-u Abnormal, Occurrences 75-10 through 75-12 were reviewed during this inspection and the findings are summarized in Table X. The inspection effort was directed at verification that:
| |
| : a. The details of 'the event were clearly reported in the 10-day letter;
| |
| : b. the cause was identified;
| |
| : c. the corrective action indicated in the 10-day report had been taken;
| |
| : d. the event and, the indicated'corrective action was reviewed and
| |
| 'valuated in accordance with the technical specifications,',
| |
| the event did not violate a safety limit, limiting safety system setting or limiting condition for operation.
| |
| No discrepancies were noted and the above abnormal occuriences axe consid-ered closed.
| |
| : 6. .Trainin Activities The licensee's training records were reviewed to verify that training and retraining of licensee personnel have been accomplished in accordance with NRC requirements and licensee commitments. The training areas reviewed and the inspector's findings are discussed below.
| |
| a, 0 erator and Senior 0 erator Re uglification Pro ram Dux'ing the inspection of October 30 through November. 1, 1974, the inspector. reviewed the actions that the licensee had taken to implement the Operator and Senior Operator Requalification Program which had been approved by the AEC Directorate of Licensing on January 17, 1974. The inspector found that the requalification program had not been fully implemented, and this item was identified as Unresolved Xtem 7414-1.
| |
| (continued)
| |
| | |
| During the inspection of February 10-12, 1975, the inspector again reviewed the licensee's activities under the requalification program.
| |
| The inspector found that some progress had been made toward full implementation of the requalification program but that the following items remained unresolved:
| |
| (1) Scheduling of the annual requalification exam.
| |
| (2) Performance evaluation of all licensed operators.
| |
| (3) Semiannual review of the emergency operating procedures.
| |
| (4) Long,-range schedule and plan for the overall training program.
| |
| During this inspection, the inspector again reviewed the training activities under the requalification program. The licensee had administered the annual comprehensive exam to all but one licensed operator during the month of April. The one licensed operator who did not take the exam is a supervisor outside of. the Operations Department who ~vill probably not seek iequalification but allow his license to expire. The licensee was in the process of grading the exams at the time of tlxis inspection. A licensee representative discussed the tentative long-range schedule and plan for next year's training. He noted that this may be changed when the exams have been graded. The inspector reviewed the records of the performance evaluations of the licensed operators and the records of the review of abnormal and emergency operating procedures. No discrepancies were found and Unresolved Item 7414-1 is closed.
| |
| ualit Assurance ( A) Trainin Quality Assurance Instruction QAX-6 entitled "PERSONNEL QUALXFICATXONS AND TRAINING FOR QA ASSIGlfrKNTS" establishes the requirements for the training and retraining of all licensee personnel assigned to perform QA activities for the Cooper Nuclear Station. QAX-6 requires that, "Cooper Nuclear Station supervisory personnel, responsible for operat-ing or maintaining systems and equipment requiring Quality As'suranre, .
| |
| shall receive formal instructions in Quali'ty Assurance, including basic principles, 10CFR50 Appendix 8, the contents of the NPPD policy document on QA fo'r Operation, and the contents of specific Quality Assurance documents prepared to implement the QA Program for Operation."
| |
| QAI-6 also establishes the following requirements for the scheduling of the above training and the retraining of the above personnel:
| |
| "Scheduling of per. onnel into the QA training sessions shall be coordinated so as to minimize conflicts with other work activities.
| |
| However, all designated supervisors shall complete the first half of the program before plant start-up. The second half shall be completed within six (6) months.
| |
| (continued)
| |
| | |
| "Refresher QA training sessions will be incorporated into operator retraining programs and will be completed within the required two-year cycle."
| |
| During this inspection, the'nspector reviewed the QA training records of- the licensee. The initial QA training was conducted on December 11 and 13, 1972 for the first half of the program and April 10 and ll, 1973 for the second half. The training records did not, however, contain any records of refresher training nor were there any records of QA training for supervisory personnel who began employment after April 1972. The licensee's Training Coordinator stated that he was unaware of any retraining in the area of QA. The inspector was subsequently informed (telephone call. on Hay 13, 1975) by a licensee representative that QA refresher training had been given in 1974 by the QA Supervisor. The inspector advised the licensee representative denoted that this item would be identified as an unresolved item pending the inspector's review of the training records for 1974.
| |
| Xn reviewing the QA training activities and QAI-6, the inspector that Section 3.1, 3.2 and 3.3 of QAX-6 establish the qualifications and training requirements for the i~fanager,'icensing and Quality Assur-ance; Quality Assurance Engineer; and Quality Assurance Specialist, respectively. Each of these Sections refers to a different Attachment (B through Dq respectively) which is to contain the minimum qualifica-tions for each of the above positions. The Attachments B through D, however, contain no qualification information. Each qualification category (Education, General Experience, QA Experience, etc.) contains only the word "(Later)". The inspector asked a repxesentative of the licensee's QA Department if the qualifications have been established.
| |
| He said that they have been drafted and are in the process of being reviewed by management. The inspector identified this item as an unresolved item.
| |
| c~ Securit Trainin The inspector reviewed the licensee's training activities relative to facility security procedures and access control. The initial training sessions were held on November 7, 8 and 9, 1973 and supplemental, infoxmation was given on December 17, 1973 which included information
| |
| : 7. Batter Poom and
| |
| 'r on the AEC (now NRC) approved Security Plan. The licensee plans to schedule refresher training in the near future. No discrepancies i
| |
| were found n thxs Vital ea.
| |
| Switchgear Ventilation awhile reviewing the licensee's commitments on the installation of fire barriers for electrical cables, the inspector noted another potential t fixe problem which had been addressed in the FSAR. By FSAR Question No.
| |
| 10.16 the licensee was requested to evaluate the potential problem in the battery room ventilation due to an archway which provided a potential for c (continued)
| |
| | |
| hydrogen accumulation and the fact that the battery room exhaust ventilation ducting and exhaust fan were to be located in the control room. The licensee's response to the above I:SAR question indicated that the above areas of concern had been corrected by:
| |
| : a. Modifying the duct work to extend to each archway in the battery room.
| |
| : b. Installing fire dampers (which close on high temperature) in the exhaust ducting for each battery room and in the exhaust ducts in each critical switchgear room.
| |
| : c. 1nstalling a standby fan which will automatically start on the failure of the operating fan.
| |
| : d. Replacing the battery room exhaust ducting in the cable spreading room and control room with explosion proof piping.
| |
| : e. Enstalling'he battery room exhaust fans in the corridor outside of the control room with the exhaust directed to the atmosphere through the roof.
| |
| The inspector examined the battery room,and switchgear room (1A, 1B, 1I: and 1G) ventilation installations. The modifications to the ventilation system had been made in accordance with the above commit-ments by the licensee. The fire dampers are of the fused-link type and had been installed to provide separation between the battery rooms and between the switchgear rooms. No discrepancies were found in this area.

| |
| .Xndepcndent conductors of power cables are insulat:ed with butyl rubber. The outer jacket: is of butyl xubbe"., neopx-.a=
| |
| PVC, H
| |
| : b. Nearly all control cable has 20 rail polyethylene (PE) insulat:ion on each conductor, covered by a 10 mil thick layer of polyviriyl-chloride (PVC). The outer cable jacket is of PUC.
| |
| C~ Area under t:hc contxol room has some automatic sprinkler fire prot:ection and the area near the sphere penet:ration has none.
| |
| Each conductor through the sphere penetration is spliced about:
| |
| 10 feet from each sicle of the penetration. The splices fall adjacent: t:o each othex in t:he cable t:rays.
| |
| C~ Alt >ough no hist:ory of splice failure exists, it: is recognized t:hat t:hc e are trouble points in any cable run.
| |
| Xn t: he sphcxcarea where many stacked trays xun under met:al grating, a cover over these should be considered.

| |
| : b. BRP PEPVC doe" not have petroleum wax inside cables (Peach Bottom plant had this wax which is very flammable)
| |
| : c. BRP field inspection showed no fire hazard due to similar Peach Bottom cable conditions.
| |
| de There are areas where trays are exposed to fire hazards due to welding above and other hazards such as spilling liquids.
| |
| : e. Xnside the sphere near. the nitrogen poison headers and just outside the sphere there are m ny splices wi< h taped points within 10 inches of a second plastic. covered splice.
| |
| : f. PEPVC was not used for the 20 foot 3ength of cable in the factory assemblies used for penetration seals.
| |
| Xt is recommended that metal covers be provided over open trays 3.ocated under metal walk grating around reactor, along turbine generator and near nitrogen poison headers. These covers are required for. t:op tray on3.y when trays are .stacked vertical.

| Cable and raceway installation control, form No. 1040.8 (2) Scheduled raceway installation, repair procedure No. RP-RAC/IE-l.
| |
| F
| |
| | |
| p (3) Scheduled cable installation, repair procedure No.
| |
| RP-CAS/lE-1. \
| |
| c~ The inspector stated that the above procedures did not provide assurance that a penetration would be xesealed if a new cable were pulled. The licensee stated that the scheduled cable
| |
| . installation checklist (Form E-700) was currently being revised to make this provision.
| |
| Visual Examina tion I
| |
| The inspector toured the facility with Mr. Gucciardo to determine the
| |
| 'extent of conformance'with the specifications in Paragraph 2. Specific areas examined were the Control Room, Cable Spreading Room, 1A3 and lA4 Switchgear Rooms, Reactor Building, Turbine Building, and Diesel Generator Rooms. The inspector found the plant to generally conformed to the bulk of the specifications.
| |
| However, the following areas of concern were identified.
| |
| P (a) Penetrations not sealed. Examples are:
| |
| (1) Opening in Marinite boar/ in Control Room (XU5X) with
| |
| ~
| |
| . no Flamemastic.
| |
| (2) Six inch sleeve 2C257 in Cable Spreading Room.
| |
| (3) Four inch conduit 2P877 in lA4 Switchgeax Room.
| |
| (4) Opening in wall between 1A3 and lA4 Switchgear Rooms.
| |
| (b). Penetrations not resealed. Examples are:
| |
| (1) Generally all panels in Control Room which have had cables added have not been resealed.
| |
| (2) Six inch sleeve 2C242 in Cable Spreading Room.
| |
| (3) Cables in Control Room have been removed from seal tight flexible conduit and the conduit not resealed.
| |
| (c) Penetrations resealed, but not conformance with specifications.
| |
| Examples are:
| |
| (1) Flamemastic replaced with Duc-Seal in Contxol Room.
| |
| | |

| |
| (4) Concrete replaced with Duc-Seal in Cable Spreading Room penetration P-804.
| |
| (d) Combustible foam in penetrations. Examples are:
| |
| (1) peneLrations which have never had the foam construction damn removed.
| |
| (2) Pc>>ctrations which have been resealed and stuffed with foam.
| |
| The inspector noted that the several penetrations in the control panel were filled greater than the 40 percent required by specifications

| ~liana emana Inaavviav A man'gement interview was conducted with Hessrs, Larson, Plant ".tanager; Clarity, Superintendent Plane Engineering and Radiation Protection; Anderson, Superint:endcnt Operations and ifaintenance; and members of the licensee's staff at the conclusion of thc'inspection on April 24, 1975.
| |
| A. The inspect:or seated that none of the penet:rations appear to have the approximate 2" thickness of Flamemastic stated by a Bcchtel Corpoxat:ion lett:cr dated Narch 25, 1975. In fact sor,",e penet:rations only have Flamcmastic coating only a few mils thick. In view that: the licensee no longer uses Flamemastic, but Pyroczcee, a Carboline product for which a minimum thickness of ~<" is recorrmended, the inspect:or zcqucseed that t: he licensee review the Bechtcl's xeco-..mendation, reach a conclusion as to the required thickness, and implement a program to upgrade the present ehexmal barrier for all electrical peneerations.
| |
| The licensee agreed to proceed with such a pxogzam. (Paragraph 3, Report Details)
| |
| B. 'he inspector noted that, using core spray pumps No. 11 and 12 as czampr'es ie appears that the separation criteria outlined in the FSAR foz cables routed through the cable spreading room i.s being met. However, duc to
| |
| , the lack of cable identification in thc room considerably more effort would be required to confirm ehc condition. (Paragraph 6, Report Details)
| |
| | |
| ~1 I
| |
| C. The inspector stated that a review of the self contained breathing equipment 'at the site, in light of'he problems experienced at another facility, revealed that, the licensee should consider:
| |
| \
| |
| : 1. 'Mhe'ther an adequate supply of air to refill used containers exists and where to obtain refills after normal working hours, specially during weekends.
| |
| 2.
| |
| Training personnel, specially the members of the emergency or fire teams in the use of the Scott Rescue Pak.
| |
| ~
| |
| The licensee stated the capabilities of the <<fonticello, Anoka, and St.
| |
| Cloud Fire Departments in supplying breathing air refills to the site will be determined. Also a training program in the use of the Scott Rescue Pak will be carried out. (Paragraph 7, Report Details)

| |
| : 2. Construction S ecifications I The specifications available at the site consisted of Bechtel'wg H-636, Revision 0, issued for construction on February 1.3, 1970 and recent correspondence between the licensee and Becntel, Corporation. For .all typical penetrations shown in Drawing H-636 Revision 0, the sealing material specified was polyurethane covered on both sides with Flamemastic 71A of unspecified thickness. The polyurethane used was made by 3ustafoam Products, Inc., and has a trade"name Insta Foam Froth- Pak.
| |
| According to a recent letter (March 25, 1975) from Bechtel Corporation the Flamemastic thickness was approximately 2 inches. The licensee has recently switched i:rom Flamemastic to Pyrocrete 102, a Carboline product,, as thermal barrier. Carboline recommends a minimum thickness of 1/4 inch.
| |
| ) C Xn addition to the construction drawings the FSAR Section 8, describes the routing and physical barriers used to separate and protect redundant channels or systems.-
| |
| : 3. Visual Examination The inspector verified that:
| |
| All cable penetrations have been sealed as required.
| |
| ~ I The control room end of the penetrations have been r'einspected by the licensee and where required a new coating of pyrocrete ha been applied, The thickness appears to exceed 1/4 inch.
| |
| Ce Xn the cable spreading room most penetrations are covered with I'lamemastic, but a few show areas where the urethane's visible.
| |
| Where applied the Flamemastic thickness appears to range from a thin coating up to approximately 1/2 inch.
| |
| | |
| 0 d; -
| |
| In the .reactor..building..most of the penetrations of cables going to the cable spreading room had very thin Flamemastic 'coa'ting" in '
| |
| the order of a few mils. . Specifically penetrations P-117 thru
| |
| 'I P-120 had little dr no thermal barrier covering the polyurethane sealing material.
| |
| : e. The same typical defici'encies noted before existed in the t'urbine building,penetrations, L
| |
| : f. In the battery room it was noted that a7.1 cables are enclosed in conduit and the penetrations are covered by. conduit termin-ating in metal junction boxes. j
| |
| : g. Spare penetrations arc filled with po7.yuxethane and cover'ed with Flamemas tic.
| |
| Smoke detectors are installed in the cable spreading room and annunciate in the control room. The det:ectozs axe supp7.ied with non-interruptible 120 V AC power.'
| |
| Cardox system does not exist at the site.
| |
| : 4. Haintenance and Hodification Procedure's The licensee does not have procedures which pecifically cover how a penetration is to be made, sealed or repaired. The licensee stated rocedurcs for a particular job would be developed as needed and 'n ~
| |
| accordance with their Adminzstrative Contxol Directives Ho. 3 Revision 1, Design Change Xnstallation Procedure; and No. 3ACD 4.3 Revision 1, Design Change Preoperational/Operational Testing. The licensee did state that the Task Force will be considering the prepar-ation of a specific procedure to cover the sealing and/or repair of cable penetrations. The inspector verified that the licensee has modified his list of critical equipment {Ali'I 3.6. 1 Revision 2) to include cable penetrations in order to require a second level'f review by plant management prior to the performance of any work on the penetrations. I
| |
| : 5. Res onse to XE Bulletins 75-04 and 75-04A The licensee had prepared a draft response to XE Bulletin 75-04 and had submitted it to his HO. lie was not awaxe whether. the response had been mailed to XE, and if any changes had been made to the draft.
| |
| Regarding Bulletin 75-04A the licensee was forming a Task Force to look into the Browns Ferry fire and the requirements of the Bulletins.
| |
| The members of the Task Force had not been named as of the time of our inspection, therefore,. the licensee's effort in the areas covered by XEB 75-04A were yet to commence.

| | |
| ~ ~ I 6.'e iaration Criteria The inspector attempted to physically determine whether the separation criteria outlined in the FSAR Section S,had been applied. Core spray pumps No. 11 and 12 control cables were u'tilized as examples.
| |
| Through the use of cable tray numbers, cable routing. lists; etc..
| |
| the pat<i of each cable from the control room to the Rx Building was traced. Physically, once the cables leave the control roon, there 3,s no marking which identifies the different cables found in each tray., Therefore, it can only be stated that if the cables follow the path noted in the reviewed drawings and schedules, then=the sepaiation criteria s'tated in the FSAR'as met.
| |
| : 7. 'elf Contained Breathin Ecui ment A review of the licensee's equipment avai.3able to enter areas of
| |
| 'heavy smoke showed that:"
| |
| : a. 'here are six (6) Scott Air Packs and two (2) Scott Rescue Paks at the"site.
| |
| : b. Each air pacl can supply breathing air for approximately 20 niinutcs and each rescue pack for approximately 4 hours.
| |
| ce There are six (6) breathing air cylinders used to refill the air bottles. Three were empty at the time of the inspection.
| |
| Approximate3y 2 air pack bottles can be refilled out of each large cylinder, so that at the time of the inspection approxi.
| |
| mately 4 man-hours of working time were available.
| |
| H d~ The large cylinders are obtained at a commercial place located in St. Cloud (approximately 30 miles) or in Anoka (approximate3y 25 miles) and can be obtained only during .normal working hours.
| |
| Although the licensee maybe able to refill the air cylinders at the Honti.cello, St. Cloud or Anoka Pi.re Departments no agreements exist wi.th the Fire Departments for such service nor has the licensee determined to what degree such capability may exist.
| |
| For the Rescue Paks the licensee maintains ten (10) spare fi.lters and two (2) oxygen bottles. Therefore, approximately 16 man-hours of use time were available.
| |
| go Host plant personnel have bean trained in the use of the Scott Air Pahks, but very fcw in thc use of'he Rescue Pak.
| |
| | |
| Additional Findi~n~s
| |
| : a. Although no procedures ex ist stating how penetration leaks are identified the li'censee stated that no flame is. ever u:".cd in the location of leaks, instead they use a smoke gener; "~r.
| |
| : b. No'procedures or guidelines presently exist covering how to fight the different classes of fire which may occur at the site ~
| |
| I 1 ll, c~ A famability test of new polyurethane was conducted 'on April 23, 1975, by the licensee and inspector. .The results were':
| |
| (1) The two fluids which comprise the Xnsta Form Froth Pak by themselves did not sustain combustion, (2) the properly mixed solid polyurethane did not but, sustain'ombustion, (3) an improperly mixed, solid polyurethane, which resulted
| |
| ~
| |
| when a defective valve in one of the canisters failed to-operate properly, did sustain combustion.

| |
| Plamemastor Dyna-Therm Coxporat:ion.
| |
| These materials are specified as non-flammable and identified in purchase order spocificat:ion on order E;664.
| |
| Thus, in summary, none of t: he materials used in sealing and iire retardant coating of these electrical penetrat:ions are at: any time flammable.
| |
| : d. Penetration Sealant and Flame Retardant S ocifications.
| |
| Det:ailed penetrat:ion sealing, fire ret:axdant application, and fire-st:op specifications are provided for eight different typos of penetrations. These spocificat:ions are provided by Pioneer Service and Engineering Company on drawing Ko. 237127A-F2639P, Revision P, 11-1-73. These pocificat ons were reviewed by the inspector prior to t: he physical examination of the various electrical penetrat:ions in tho plant:. Several minor deficiencies were observed as follows:
| |
| (1) One non- afety related cable in a multi-cable penetration from the relay room to tho cont:rol room was <<ot coated with a flame-retardant material. Xt appeared that this cable had been installed after t: he penot:ration was origi>>
| |
| nally sealed. The cable was firmly packed i<< fiber glass
| |
| | |
| wool.to provide a'eal, however, no flame retardant had been applied dixectly on this single cable. All other cables were coated with flame retardant material.
| |
| (2) Three 2" conduits originating in the relay room and terminating in the control room were not sealed, that
| |
| 's, a draft could bc felt: at the Control room end of these conduits.
| |
| (3) Two 2" spire conduit openings between the Relay room and the Auxiliary buildings were not sealed.
| |
| (4) At several electrica1 penetrations fire stops, the flame-mastic 71A fire retardant material was observed to be cracked, apparently due to shrinkage upon drying. This cracking up to <" in width, did not provide a pressure/smoke seal around the fire-stop.
| |
| The licensee is currently examining all safety related electrical penetrations for conformance to the specifications identified above. The licensee has stated the intent to correct any deficiencies found, including the four identified above, as expeditiously as time and plant conditions allow.
| |
| The. four deficiencies are not considered as immediate'y serious by the inspector since they pose no fire propogation threat, but zathez a smoke control pzoblem. This plant utilires a multi-mode ventilat'on systein"/ which is designed to assure that smoke from any other portion of the plant can be prevented from entering the contxol room or. can be swept out if it originates in the control room. As a backup measure the in-spector observed that there are two self-supporting air
| |
| ~
| |
| breathing masks available in the control room. Also this plant is designed with the capability for a shut-down from out ide of the control room. This capability was demonstrated as a part of the plant start-up and power ascension testing.2/
| |
| Duxing this inspection the inspector re-reviewed this capa-bility. Xnspections at the control cabinet vexified that 3 contxol center, multi communications systems, and procedures /
| |
| are current and ready for use.

| |
| Quality As uxance Supervisor, plus a review of 'plant'work request and modification records indicate that none of the safety related electrical peneerat:ioris 'have born disturbed since final conseruction. Thus, there has been no need for special pxocodures for ro-sealing an electri.cal penetration.
| |
| General maintenance procedure Gi'F No. 202, cable pull, carries a note to remind personnel'f t:ho need t:o xoeurn ehe ponetrationeto "Ori'ginal st'acus" after ea'ch cable-pull activity.
| |
| However, this procedure does noe reference tho con t:ruction speci.fications referenced in it:om 1-D above. Tho licensee will consider listing this reference in futuro revision of G))P 202, na The licensee does not believe that individual penetraeion seal testing to insure tnat a t:otal pressure seal exists is necessary for penetrations other than containment boundary pcnetrat:i.ons.
| |
| This position is based on dosigned independe>>cc-between t: he various plant ventilat:ion control systems to permit sweepin of smoke from e)>e various portions of the plane wit:houe t: he smoke being int:roduced into the control room. The separat:o cont:rol room vent:ilat:ion system is designed with the capability to purge any smoke originating in the control room directly t:o .
| |
| atmosphere, or to opexat:e in a t:otal recirculat:ion, totally filtered mode. Thus, the licensee doe noe int:end to perform individual penetration seal t:est:s. They do intend to adhere eo t: he penet:ration specificat:ions of item 3-d above in providing a flamo st:op, flame retardant fire barrier type penetration with reasonably tight smoke limiting seal. The inspector's review of PSA)'. and t: he ponetrat:ion specification indicates t:hat neither specifics t:hat a measurable pressure seal exist:,
| |
| but rather that a "Pire )3arrier" exise. No open flame is u ed in the t:eseing of seals or penetrations in'the Plane.
| |
| : 5. Com lienee nits final Safetv'Analrsc~s Re ert Other it:ems inspect:ed and compared against: the commitment of ehe PSAR include the following: (sampling basis only)
| |
| The Hain Auxiliary, Reserve Auxiliary and Tertiary Auxiliary Transformers are located outdoors and are phy ically separated from one another by firewalls. Each transformer cell, formed by the firewalls, has an automatic water spray syst: em to extinguish and prevent: eho spread of fires.
| |

The number is applied when-ever there is a chango in identity or. when pa sing through floor ox wall openings. This number is applied prior to the pulling of any cables, and the color established the syst: em to which it is assigned'or the non-Class lH systems thx'oughout thc remainder of the plant, trays installed in stacks are spaced vertically with of 12" bottom-to-bottom in all areas. Ilowever, Class a'inimum 1E trays have a minimum of 15" bottom-to-bottom between trays of the same train. Class lE trays contain'ing instrument, control or power cables have a minimum horizontal separation between redundant circuits of 36". Redundant circuits are not permitted in the same tray or conduit. Tf closex spacing

| : 3. Maintenance and Modification Procedures .
| |
| The licensee stated that there are no specific modification procedures to ensure. that fire stops and compartment boundary seals are maintained on a continuing basis. The licensee stated that all work is accomplished through the Station Work Request program and thus is sub)ect to the Operations Quality Assurance Program.
| |
| 4~ Visual Examination The inspector toured the facility with Mr. Stolt and other representatives of the licensee to determine the extent of conformance
| |
| .with the specifications in paragraph 2. Specific areas examined were
| |
| 'the Unit 1 Cable Penetration Room, Units 1 and 2 Cable Spreading Rooms, the Unit 2 Aux.'lectric Room, and the Control Room.
| |
| The inspector identified three general areas of concern:
| |
| : a. Combustible materials at various locations:
| |
| ~
| |
| (1) Wood blocks supporting a cable tray.
| |
| (2) Wood in conduit sleeves and cable trays.
| |
| (3) Foam in conduit sleeves and cable trays.
| |
| (4) Unidentified ropclike material used to seal some conduit sleeves. 'I
| |
| : b. Unsealed Penetrations:
| |
| (1) Some penetraHons had not been sealed at construction, e g., D-24 A through D-24 F.
| |
| (2) . Several conduit sleeves into control panels which were installed for spares but were never capped or sealed.
| |
| (3) Penetrations which have been opened to pull new cables and have not been resealed.
| |
| Co Cellular Concrete:
| |
| (1) While observing a penetration which had been opened
| |
| .to pull a new cable and not-resealed, the inspector noted that the penetration was not solid with concrete as the specification indicated, but instead was only filled to a depth of about an inch.
| |
| 5
| |
| | |
| 0 (2) The inspector noted that <he concrete was cracking and crumbling in many locations.
| |

'he '009 procedure covers con-struction of the Category I ventilation,'team exclusion, and fire barrier seals around electrical cabling penetrations. The licensee considers the steam exclusion seals as fire barriers both are similar. construction.
| |
| The cable trays either have RTV poured over the random layered cabling,and the remaining volume packed wi'th fiberg'lass "board" or in th'e case of power cables, only the fiberglass "board is used.
| |
| The fiberglass "board" and cabling is then sealed with Flamemastic
| |
| ~
| |
| 71A in two 1/8" coatings on both sides of the penetration. The seal vcpification 's the quarterly ventilation test to verj.fy that the auxiliary building does go to a negative pressure. No devices are used to check individual seals.
| |
| The above Comstock procedures are to be used for repair of a disturbed seal.
| |
| The construction drawings and applicable procedures follow the separation and barrier criteria in Section 8 of the FSAR. The color coding of the cables was performed as the cable was removed from the reel and all power cable is armored with semi-flexible aluminum sheathing. All cable in the plants is specified as Type I and meet the "Philadelphia Flame Test".
| |
| : 3. Visual Examination The following areas were inspected where applicable to the fire barriers:-
| |
| Control Room Relay and Cable Pulling Room (Relay Room) 1/ "Electrical Conduit Seals" in the biological shield.
| |
| 2/ Sealing Electric Openings.
| |
| | |
| Turbine Building ~
| |
| Auxiliary Building Di.sel Generator Rooms Bus Rooms (Switchgear for Busses 15 and 16, 25 and 26)
| |
| In these areas the steam exc'lusion and fire barrier 'seals (approxi-mately 40% examined) were found to be as specified except as follows:
| |
| : a. Two, cab~ tray penetrations were not sealed with Flamemastic on the Relay Room side.
| |
| : b. In approximately 20% of vertical penetrations the Flamemastic has not bonded to the concrete on some part of the penetration periphery and the fiberglass could be seen. The lack of bonding was also noted on some of the cabling in this type of penetration. The above was noted only on 'the top seal of these penetrations.
| |
| Ce In the vertical penetrations that have 3 or more layers of cables the internal cables did not appear to be completely sealed with 1'lamemastic in the fire barriers. This did not appear to be a problem in steam exclusion and Category I ventilation seals as RTV is poured into these seals. The
| |
| 'icensee agreed to review this area and correct as necessary.
| |
| This item was not fully covered 'in the procedure .and the fire barriers are as specified.
| |
| The "Permagum" (duct seal) which is flariunable was used as dams for pouring RTV (Unit 1) or Chico (Unit 2) into conduit for sealing and is probably still in place. This annulus area was not inspected.
| |
| Permagum was used to seal stub tubes in the penetration seals that have wires running througli the tubes and the majority are not coated with Flamemastic. Permangum is the only flammable material used in the seals as RTV apparently only burns on surface and the char protects the remaining seal.
| |
| : 4. Maintenance and Modification Procedures The licensee has initiated a procedure that routes to the Electric Engineer any work request that requires cable pulling through an existing seal or barrier. He reviews the work request and adds the applicable original construction sealing procedure to be used for repairing the s'eal. No modifications have been'ade in the 4 week period that this procedure has been in effect. The licensee is continuing the review of previous modifications and it appears that the new cabling has pulled through the stub tubes that are part of the seal. The tubes are either capped if not in use or fiberglass is packed around the wires and the ends of the stub tube is sealed with "permagum". The "permagum", in some cases, was sprayed with
| |
| | |
| flamcmastic the majority of stub tubes in use have temporary cabling pulled through them and the licensee is evaluating covering the "permagum" with Flamemastic.
| |
| : 5. Res onse to IE Bulletins No. 75-04 and No. 04A The licensee's response to IE Bulletin No. 75-04 has been received.
| |
| The licensee stated that .ignition sources as used 'in paragraph 3 of the response presently refers to welding and grinding, but is also
| |
| 'to include other sources i'f any are used in the future. Northern .
| |
| States Power Company has formed a task force of personnel 'from both the licensee's nuclear sites. -The initial meeting was held May 5, to set up the guidelines and the next meeting was scheduled for May 1'4.
| |
| Monthly progress reports are to be sent to IE until June 30, the scheduled date for completion of the response to the bulletins.
| |
| : 6. Se aration Criteria The requirements and specifications of the construction prints, the electrical wiring procedures 'and the FSAR, Section 8, appear to have been met as to the- separation and barriers. The physical tracing of individual wires in a cable tray could not be performed b{ ~~end he firsl pefi
| |
| < ctrl tlon as the cables lcf, the control <<oom or the termination point. The construe'tion QA personnel have completed a 100% inspection of the barrier requirements using the prints and color coding with no deficiencies noted. The cable pull cards had previously been verified.
| |
| 7 ~ Fire Fi htin E ui ment The fire fighting equipment available at the site consists of hose sta'tions with fog or adjustable nozzles, portable C02, purple K fire extinguishers in the plant and 2'ater extinguishers outside the control room doors. The relay'and cable pulling room has an automatic Cardox system with manual start pull box The diesel generator rooms have automatic water sprays. The fire detection system consists of ion smoke detectors and bimetallic temperature elements which alarm in the control room. The self contained
| |
| .breathing cquipmcnt was purchased for the purpose of ai,rborne activity protection, 'but could be used for fire fighting. The equipment now on site is four single bottle Scott air packs with four spare botties and four large 'cylinders that can recharge approximately 20 bottles. Each of the charged bottles provides approximately 30 minutes of working time. The person knowledgeable of how the cylinders are recharged was not'vailable at the time of
| |
| | |
| the inspect9.<n. One Scott Rescue Pack with one spare .oxygen bottle, each worth approximately 30 minutes, was available at the site. The Red Wing-Fire Department will respond to a fire at the site and they have held fire fighting, classes for the site personnel.
| |
| A training memo was issued by the Training Supervisor on Hay 6, 1975, outlining the training to be held in reference -to the Brown's Ferry fire. The memo also refers to the National Bureau of Fire Underwriters Special Interest Bulletin No. 91 that lists safe distances vs. voltage for use of water fog on eneMgized electrical wiring fires.

| |
| : 2. Construction Specifications V
| |
| Alii.s-Chalmers and Sargent & Lundy construction specifications were xcvi.ewed to d termine what req'uirements exist for fire barriers and boundary seals. No specifications exist for 'these two areas. However, A'-C specification 41-4'91 "Specs for Electrical Design Features" requixes that reactor building cable pans have solid bottoms and sides. The inspector confirmed that cable pans in the reactor building are so constructed. .Also, reference drawings in S&L STD-EB-134 indicate that the minimum distance between horizontally stacked trays be 10 inches.
| |
| : 3. Maintenance and Modification Procedures
| |
| ,The following .procedures relating to 'maintenance and facility change controls were reviewed to detexmine whether requirements are impos d in connection with modifi.cations and repairs to cables and.penetration boundries.
| |
| : a. "Design Control and Review" ACP-04.1
| |
| : b. "Facility Ch"nge Requests" ACP-04.2
| |
| : c. "Maintenance Requests" ACP-17.3 These procedures provide sufficient review for maintenance and mod-ification activit'ies. Also, procedure ACP-0.4.1 states that the Plant Engine-ring Staff is responsible for establishment of a suitable test program as necessary to accomplish d sign reviews.
| |
| Revi.ew df procedures ACP-04.2 and ACP-'17.3 showed that no provi.sions exists to include independent verification of job completion if and when required. The licensee stated that the "Quality Assurance Program" manual procedures are continuously being upgraded and independent verification requirements will be included as required.
| |
| Xn regard to the second emergency diesel genera'tor installation, the inspector asked what controls would be followed prior to and during this installation. The licensee replied. that procedures would be written for this installation activity.
| |
| | |
| Visual .Examination
| |
| 'he inspector toured the following areas to determine the licensee's conformance with installation and construction specifications
| |
| &o Control Room cables penetrate the floor and are sealed through metal plates by compression fittings. It appears that this 'type penetration is adequate to serve as a -fire stop.
| |
| : b. Electrical E uioment Room in this area cable penetrations exist be'tween the control room (metal plates), the mezzanine floor of the Turbine building and cablepenetration room (outside the northwest quadrant of the containment shell);
| |
| I Cable pans in this room have solid bottoms and sides and are sprayed with a fire-proof material .(Flamemastic 71A). In all sections where cables run from one cable pan to another Flamemastic 71A is used. Also, Flamemast'ic 71A is sprayed 3 feet.,on both sides of wall penetrations. Vertical cable runs in this room are enclosed in solid cable raceways. The xoom also contains the station batteries.
| |
| Co Turbine Buildin (~Lfezzanine Floor) -'lamemastic 71A is used "about every 10 feet in the horizontal pans and at each cable pan junction. Cables penetrating the mezzanine floor and going to the grade floor below are fully enclosed.
| |
| 'd ~ Diesel Generator Room power cables are totally enclosed in conduit and run into the concrete floor.
| |
| : e. Cable Penetration Room in this'oom cables from the primary containment penetration seals run vertically into horizontal pans and at this point and along the horizontal run are sprayed with Flamemastic 71A. This cable penetration room is presently being used for storage of items such as electrical extention cords, welding rods, tools, etc.
| |
| Containment cable pans in this area are fully enclosed except where the cables enter and leave the pans at which point they are. sprayed with Flamemastic 71A. Cables for the emergency core spray system, water level instrumentation and the emergency shutdown condenser are copper-sheathed, mineral insulated, fire-proof cables and run to the equipment itself.
| |
| 4
| |
| | |
| In the areas examined the inspector noted that all wall penetrations are filled with fiberglass material and Flamemastic is "sprayed on both sides of the penetration.'he 'licensee stated that Flamemastic 71A was first applied in'eptember 1972 for fire insurance purposes.
| |
| Except for the Diesel Generator compartment, all areas examined have one or more fire extinguishers, also all these areas employ fire/smoke detection sensors that alarm in the control room. The licensee stated that he will consider placing a fire extinguisher outside the door of the Diesel Generator, room.
| |

Sco e of Ins ection The inspection vas performed to 'determine the requirements relating to compartment boundary seals and fire stops for electrical penetra-tions, imposed by facility construction specifications, foz the Edwin I. Hatch Nuclear Plant and to determine the extent to which the facility currently conforms to these requirements.
| |
| Particular inspection effort vas giien to the follovirig major areas:

| |
| : 3. Desi Information a.'onstruction S ecifications Georgia Pover Company drawing A-13029, "Electrical Seals", establishes a guide of basic specifications and details for general fixe stops and seals for cable penetrations in floors and walls of the Hatch Nuclear Plant. This guide does not address the secondary containment fire stops and pressure seals consisting of modular units, identified as Multi-Cable Transit (MCT), manufactured by Nelson Electric Division
| |
| ~ .
| |
| of Sola Basic Industries. The frames for these modular units are detailed on construction dravings. The specifications for" the general fire stops and seals and a brief description of the MCT modular units are discussed below.
| |
| | |
| IE Rpt. No. 50-321/75-6 l-2 Floor Penetrations Cable trays entering the floor of the cable spreading room are sealed to provide a fire barrier and insure a ventilation seal. Specifications require that one-half inch Harinite-36 was to be used as a form beneath 'the floor, cut to fit around cables and cable tray. Mineral insulating wool was, to be used where necessary to Sill large voids around the cable. Flamemastic 71A sprayable was to be applied to the cables in the penetration as well as a minimum of twelve inches below the penetration'.
| |
| Flamemastic 71A mastic was to be applied over the holding screws and between the Harinite'panel fo'rm. Flamemastic 71A sprayable was then to be built up to approximately 1/4 inch on the bottom of the Harinite form around the cable's and cable tray, at their ~
| |
| entry through the form, to insure a fire stop and ventilation seal.
| |
| The top opening of the penetration was to be covered with a steel plate or a piece of 1/2 inch Harinite-36 board to prevent debris from gathering into the penetration.
| |
| within the reactor building (secondary containment) most floor penetrations between levels consist of 'either embedded walker
| |
| 'duct'r embedded conduit. Mineral wool was to be installed in the bottom side of the penetration to was fill voids.

The construction of the fire stop is much the sama as described for floor penetrations. The exceptions being that Harinite was required only on one side of the wall, and Flamemastic 71A was to be applied to the cables for a minimum of 12 inches on either side of the wall and inside the wall opening, if possible.
| |
| (3) Cable Tra Pire Stops Fire stops were to be placed in all cable trays at approximately 75 foot intervals. Construction was to consist of a one-half inch Harinite-36 panel placed around cables and cable tray and secured to a support strut. Mineral insulating wool was to be used where necessary to fill large voids around the cable. The cables in the cable tray were to be sprayed with Flamemastic 71A, twelve inches on either side of the fire stop. Flamemastic 71A, mastic was to be applied to a minimum 1/8 inch thickness over the holding screws and applied to fill the crack between the two pieces of Harinite, cut to fit around cables and cable tray.

| 0 IE Rpt. No, 50-321/75-6 I-3 Flamemastic was then to be built up to approximately 1/4 inch on both sides of the .Harinite panel l
| |
| In vertic'al cable trays, a cover was to be installed on top anc,bottom (if not a solid bottom tray) of the tray. This cov:.g was to be placed on the upper side of the fire barrier and was to extend at least five feet beyond the barrier.
| |
| (4) Seconda Containment Pressure Seals and Fire Sto s Conduit sleeves exist between the control building and reactor building. These conduits are sealed to allow the reactor building to be maintained at a negative pressure. The seals are similar installed for the diesel building wall seals described later to'hose in this report. The difference being that conduit sleeves are extended through the wall between junction boxes, and circuits feeding into the boxes are totally enclosed in conduit on both sides. of the wall.
| |
| Wherever cables from cable trays penetrate the secondary contain-ment from the cable spreading room or control building, the penetration is made through a Nelson Electric Hulti-Cable
| |
| 'Transit {HCT) module which provides both a seal and a fire stop.
| |
| The TECRON (tradename) module fits snuggly around each cable.
| |
| These modules expand when heated, choking off fire and smoke.
| |
| This expansion supposedly compensates for the loss of cable insulation, burned away by a fire, thus maintaining the fire-tight integrity of the penetration.
| |
| .(5) Control Room Floor Pressure S'eals Cable penetrations between the cable spreading room and control room panels were to be sealed with a flame retardant BISCO flexible silicon'e foam. Penetrations under the panels consist of recessed aluminum plates with multiple holes used to accomodate chase nipples, terminated conduit or flexible conduit extended through a hole.
| |
| Spare holes in the aluminum plate were to be blocked and sealed with duct tape or extended into the panels with short lengths of aluminum conduit sealed on the spreading room side of the pene-tration with a penny and bushing arrangement, prior to placement of the sealing material.
| |
| The area under the control room panels was to be filled with BISCO flexible silicone foam, by Brand Industrial Services, to at least the embedded strut in the recess.
| |
| | |
| XE Rpt. No. 50-321/75-6 T-4 (6) Diesel Buildin Hall Pressure Seals The penetrations between the diesel rooms and switchgear rooms are to be sealed. Each penetration sleeve was to be sealed by injecting RTV sealant into the spaces between the cables of the bun'die. The injection was to start within the penetration as far as practical and was to extend to some two inches out of the. penetration. Mineral wool was to be packed into the penetra-tion around each cable bundle to within about 1/4 inch of the penetration opening. RTV sealant was then to be applied onto in, and around each penetration to cover the entire assembly with sealant not less than 1/8 inch in thickness.

| |
| : 2. Reactor Blow Downs A reactor blowdown occurred April 29, 1975, from approximately 10%
| |
| power when the B relief valve (RV) lifted for no apparent'ause and failed to reseat. (Abnormal Occuirence Report from CP&L dated May 16,
| |
| .1975). A second blowdown occurred May 6, 1975, from about 600 psi while restarting the plant from the April 29, 1975 blowdown. The inspector reviewed CP&L's investigation of first event and portions of the second event, including instrument charts and computer printouts.
| |
| The following items appeared to be pertinent to these events:
| |
| | |
| 1 e IE Rpt. No. 50-324/75-6 a~ The first alarm received was high torus level and the second alarm was high temperature in the torus. Each relief valve discharge line
| |
| 'as a thermocouple in the line to detect relief valve leakage by measuring the temperature, and to provide an alarm when a relief valve .opens. The temperature in each "tail pipe" is recorded sequentially on a multipoint recorder. The high "tail pipe" temperature alarm which comes off the recorder, is normally set 50 F above the maximum temperature being measured, however, the proper setting had not yet been determined in the startup program.
| |
| As a result, the alarm was on because of a high ambient temperature
| |
| .in another "tail pipe." When the "B" relief valve opened another alarm for high tail pipe temperature was not initiated.
| |
| : b. Relief valve operations are not monitored by the computer, or other annunciators. At the time of both blowdowns, one main steam bypass valve to the condensor was open. The closing of the steam bypass valve (as a result of the relief valve opening) was recorded on the computer. -This provided the time that the relief valve opened.
| |
| Co When it was determined that a relief valve was stuck open and would not reseat during the first blowdown .(about 10 minutes after the RV opened), the reactor was not scrammed immediately as required by Emergency Instructions EI-40. The main steam isolation valves were closed aoout 20 minutes after the relief valve opened. This action scrammed the reactor. A licensee representative stated that this action was taken to minimize the cooldown rate since the reactor contained a new core with very little exposure and very low decay heat removal requirements. During this period, EI-40 requires that the reactor be scrammed as soon as it is recognized that the RV will not close, or if the suppression pool temperature reached 110 0 F.
| |
| EI-40 also requires initiating all available RHR heat e..changers in suppression pool cooling mode as soon as possible. An attempt was made to initiate fuel pool cooling with the "A" loop; however, the suction valve would not open. Fuel pool cooling was not estab-lished with "B" loop until 12:40 p.m., 18 minutes after the relief valve opened. The computer showed that the "C" RHR sexvice water pump started at that time. Operation of the RHR pumps was not mon-itored by the computer. During the second blowdown, the operator piomptly scraped the reactor and initiated torus cooling as requir'd by procedure EI-40. (The failure to follow procedures was identified by the licensee as an item of noncompliance with Technical Specifi-cation 6.8, and reported to IE:II as an abnormal occurrence in CP&L letter dated Hay 16, 1975.)
| |
| d4 Following the first blowdown the specific cause of the RV sticking open was not determined, however, iron oxide was found in the
| |
| | |
| 0 4
| |
| | |
| pilot valve and in the second stage of the relief valve. No other abnormalities were detected; therefore it was concluded that the iron oxide had caused the problem. The pilot valve and the second stage of all other RV's, except "A" RV, were disassembled and cleaned. ("A" RV was cleaned during a reactor outage about April 1, 1975). FoIlowing the second blowdown on May 6, 1975, the solenoid valve that supplies air for manual operation was still blowing when "B" valve was initially examined indicating that the solenoid valve was stuck in an intermediate position. Piston in-spection .of the partially disassembled solenoid valve showed that an 0-ring was not seated .on the piston that closes the exhaust air port and connects to the piston that admits air to the relief valve. This same 0-ring was found partially seated in five of the other ten solenoid valves. During a "Bench Test" of the "B"
| |
| . solenoid valve, the solenoid valve piston would intermittantly stick in the intermediate position. The necessary replacement parts were obtained and installed under the direction of the
| |
| ''manufacturer representative. The onsite QA group monitored the repair of the relief valves including the solenoid valves using a procedure with hold points developed for this job.
| |
| Each solenoid was functionally tested following repair, and each relief valve was scheduled to be functionally tested at 250 psi and flow tested at approximately full pressure (1005 psi) during the subsequent startup.
| |
| : e. -When the main steam isolation valves were closed, the turbine driven reactor feedwater pumps were tripped off by the loss of steam to drive the pumps; however, the pumps continued to coast down. While
| |
| 'the high pressure feedwater heaters were being valved out, the operator bumped the control for the high pressure heater bypass valve. The bypass valve opened full, allowing reactor level to increase to the point that the main steam lines flooded. .The con-trols for the heater bypass valve are on the control board between the controls for the high pressure heater isolation valves.
| |
| Technical Specifications limit the cooldown rate to 100 per hour.
| |
| With the "B" relief valve open, temperature decreased from 517 F to 314 F in 10 minutes. A site vendor representative determined that this rate was less severe than the loss of feedwater pump with main steam isolation valve closure (320 in 3 minutes 40 seconds) that was evaluated as part of the vessel thermal cycle analysis.
| |
| Following the first blowdown, a visual >nspection was made of the suppression pool including the welds where the "tail pipe" passes thru the downcomer vent header, and below the water level in the torus using a diver. No damage or defects were identified.

| |
| ~ 3 A visual inspection was made of the fire stops in the diesel generator building, the reactor bu'ilding, the control building,'he turbine building and the radwaste building on Hay 5-9, 1975.
| |
| The penetration firestops were compared with Specification No. "
| |
| 9527-01-48-1, and the individual area prints. The location of penetrations on the points were compared with the as build loca-tion. The results are as follows:
| |
| Q.) Diesel Generator Buildin Most of the cable coating, (flamemastic) has been applied as specified; however, new cables have been pulled and/or insuf-ficient flamemastic has been applied to five fire stops out of a total of fifty-two fire stops inspected. In addition, eleven penetrations contained holes ox sleeves that were not plugged in accordance with CP&L specifications. Four fire stops were identified with the wrong material, and one penetration was not specified; and contained an open sleeve. Three conduits were identified with the conduit cover removed; (2) Reactor Buildin During the inspection, work was in progress to apply flamemastic to fire stops in the reactor building. The following indicates the status at the time of the inspection:

| ductseal, urathane foam, etc.)
| |
| (3) Control Building Of twenty fire stops identified and inspected, eleven contained
| |
| 'openings that were not sealed or were improperly sealed.
| |
| The flamemastic coating had not been applied-to any cables. A sampling inspection of openings in the floor of control room cabinets showed about 10% unsealed. An unspecified foam backing
| |
| 'aterial was found in one vertical firestop.
| |
| (4') Tur'bine Buildin Of fifty-six fire stops inspected, fifty-two contained openings that were not sealed and/or an incomplete coating of flamemastic.
| |
| (5) Cable Tunnel Flamemastic had not been applied to the cables in the cable tunnel.
| |
| The specifications require a coat'ing of at least ten feet every fifty feet. Eleven of fifteen penetrations were not plugged. One large group of penetrations at the end of the tunnel was not plugged or coated, and w'as not shown on the installation prints provided.
| |
| (6) Radwaste Buildin Sixty-four fire stops were inspected'n the radwaste building.
| |
| Fourteen of the fire stops inspected contained one or more unsealed openings and/or incomplete flamemastic coating. Several penetrations were identified in the field that did not show on the installation prints. A large number of penetrations shown on the installation prints were not used.

| |
| "3. Facilit Construction Specifications
| |
| ? Section 8.2.2, Power Distribution System, of the'H. B. Robinson FSAR contains the paragraph "To prevent spread of flame, fire barriers of glass wool packed around trays on approximately 10 foot spacing in vertical runs has been provided. Fire barriers of similar construction are used in all trays when they penetrate walls."
| |
| The licensee's answer to Question VF, in the response to AEC Questions, relating to reactor trip and engineered safety features circuitry, contains the sentence "In instances where physica1 conditions prohibit hori.zontal separation, horizontal fire barriers are provided."
| |
| The licensee is unable to locate any documentation to show that the commitments of the FSAR were met during construction. The inspector requested to see the following type documentation and was informed that it.was not available.
| |
| : a. Construction drawings or specifications'showing the location, type, number, materials and assembly details of the barriers.
| |
| : b. Material specifications to include procurement specifications and fire resistant characteristics.
| |
| : c. Material qualifications by Mil-Spec 'or other approved tests.
| |
| : d. Qualification of an actual or simulated assembly through testing.

| |
| : 4. Maintenance -.and Modification Procedures The licensee does not have procedures Xor inspection, maintenance or repair of existing barriers. Numerous cases of barrier breaching are discussed in item 5, below. Procedures do not exist for installation of fire barriers when new wall or floor penetrations are established for cables required by plant modification.
| |

| : b. ~Tra s Barriers for floor penetrations from the control room down to the cable spreading room have asbestos board on the underside of the floor with a mastic applied on the upper side over glass wool. The following was noted by the inspector.
| |
| (1) Much of the mastic has been broken while some is missing.'2)
| |
| Barriers were not established when the Axial Power Distribution Monitori'ng System Panel and The Turbine Startup Panel were installed in the control room.
| |
| (3) A modif'ication in The Radiation Monitor Panel caused breaching of its barrier and was not repaired.
| |
| Except in isolated instances it appears that fire stops were provided for all wall and floor penetrations throughout the plant for safety related cables. In some hard to get at places the mastic was poorly applied. Numerous barriers have been breached through plant modification or -.maintenance and not returned to their original status. The unavailability of documentation showing original specifications and requirements is the licensee's reasons for not repairing breached barriers or installing barriers for new

| Licensee Actions Requested b IE Bulletins 75-04 and 75-04A Response to these two bulletins was provided in CPSL letter dated April. 24, 1975. -It was stated'hat final response to 75-04A would. be completed by July 31, 1975, with progr'ess reports submitted monthly.
| |
| It would be expected that all the construction documentation would have been received from Ebasco and the necessary corrective action taken regarding the deficient barriers by that date.

Davis Field Engineer, Construction This part of the inspection'involved obtaining information on fire stops used at Oconee. The Oconee FSAR, Section .8.2.2.13.g, states that floor sleeves will be filled with a fire retardant material. Section 8.2.2.13.h states that wherever physically pospible, metallically armored and protected cable systems will be used and that with this type construction fire stops as such are not required. The licensee, however, is presently installing and reworking fire stops in the.
| |
| following areas: (a) turbine building to auxiliary building, (b) elec-trical equipment room walls, (c) electrical equipment room ceiling to cable room, (3) cable room walls, and (e) cable room ceiling to control room. Information presented herein concerns practices and materials presently. being used by the licensee.
| |
| : a. Materials The following materials are being. used in fire stops at Oconee:
| |
| (1) Flamemastic is a fire resistant material 'sprayed on safety related control cables crossing power cable trays.
| |
| This material is commercially available and tested by a method that follows in principle American Standard ASTM E-119.
| |
| | |
| XE Rpt. No.'0-269/75-6 I-2 (2) Glastic is a UL recognized flame retardant glass mat polyester laminate. The thickness used at Oconee is 1/8 inch. This material was tested according to ASTH D-229 Method I. I (3) Monokote is a plas'ter 'like material used for fire proofing
| |
| 'nd tested and rated by Underwriters'Laboratories, Xnc.
| |
| in accordance with test method ASTH E119. A 2-1/2 inch thickness provides fire proofing for approximately 4 hours.
| |
| Thh licensee uses a minimum of four inches in fire stop applications.
| |
| (4) Armaflex - is a rubber like material used in approximately 1 inch thick sheets for sealing against air flow. Xt retards burning and has been tested per ASTH D 1692 and by the licensee with a torch.
| |
| The above materials are corr~erically available and are purchased through a local contractor.
| |
| : b. Installation
| |
| ~ A licensee representative stated that efforts .were recently initiated to upgrade fire stops at Oconee. This is being conducted in two phases. All open penetrations through walls that are fire barriers are to have fire stops installed. The inspector observed several 6 inch diameter penetrations in the cable spreading room ceilings that opened into the control rooms
| |
| ~
| |
| above that did not have fire stops installed. The licensee stated that installation of fire 'stops would be completed in about three weeks.
| |
| The second phase involves reworking old fire stops and adding Monokote to a minimum thickness of 4 inches.
| |
| 1
| |
| ~
| |
| Several configurations are planned for fire stops at Oconee as follows:
| |
| (1) Where cable trays penetra'te walls, either Armaflex or 1/8 inch thick Glastic for air sealing and a minimum of 4 inches of Monokote for fire stops will be used.
| |
| (2) Where empty pipe sleeves in floors or walls exist 1/4 inch
| |
| , thick steel plates will be tack welded in place to cover these openings.
| |
| | |
| ~ ~ ~
| |
| IE Rpt. No. 50-269/75-6 (3) Where pipe sleeves, with cable, piping or instrument lines "
| |
| exist Honokote held in place by wire and steel supports will be used. Some will have approximately 2 inch conduit instalged for temporary instrumentation cables and asbestos cloth will be used as packing.
| |
| (4) Small cable shafts between the cable spreading rooms
| |
| ~ ~ and the control rooms will be sealed with 1/8 inch Glastic and Monokote.
| |
| A licensee representative stated that no testing has been accomplished on fire stop assemblies.
| |
| : c. Administrative Items
| |
| . It appears that there is no specific requirement'or repair of fire stops and re-inspection of reworked areas at Oconee. A licensee representative stated that such a requirement is being considered.
| |
| Licensee representatives stated that there is no requirement against smoking or control of flamable materials in the cable spreading rooms or equipment rooms. Concern was expressed with regard to this policy to Duke Power Company .corporate management by telephone on May 8, 1975.
| |
| The licensee response to IE Bulletin 75-04 and 75-04A has been received by Region II. Licensee corporate management stated, on May 8, 1975, that an additional response to bulletin 75-04A would be submitted after additional review of the subject is completed on June 16, 1975.
| |
| : 3. Oconee 2 Reactor Coolant Flow The licensee reported that indications of Unit 2 reactor coolant flow, from a secondary system heat balance were above the core lift valve of 11.9% of design flow but that instrumentation problems were suspected.
| |
| On May 4, 1975, the licensee reported that, after further testing of instrumentation used in heat balance determinations, the Unit 2 flow appeared to be 111.5% of design flow. Further testing is being conducted by the licensee to attempt. to verify whether or not core lift is occurringo This matter has been referred to the Office of Nuclear Reactor Regulation (Licensing) for further review.

| IE Rpt. Nos. 50-250/75-7 I>>2 and 50-251/75-7 A construction installation procedure dated 4/10/70 identified as Job No.'610, Dwg 5610-E-310, states in Section III, "Raceway's passing through walls, ceilings, or floors shall have a fire stop such as shown on Plorida Power and Light drawing A-GO-4 and A-G0-5."
| |
| These drawings are the same as shown in the FSAR and are appended as Figures 1 and 2 of this report.
| |
| Only the above listed general statements regarding location of fire stops were made availabge to the inspector. The licensee stated that no master list of .fire stop locations existed; An inspection was conducted to determine the application and extent of application. of fire retardant coatings and the location and con-of fire stops. The inspection covered .the following areas. 'truction (a) Fire st'ops for power cables from the unit auxiliary trans-former through the wall of the 4160V switch gear room were examined. Fire stops, as described in Pigures 1 and 2 attached, were in place and were in good condition.
| |
| (b) Fire stops for Power control cables from the 4160V 3 switch gear room to the 480 .volt switch gear were examined.
| |
| The fire stops were in place. Some .new power cables had been run from the 4160V switch gear to newly installe'd eon-
| |
| ' densate pumps. These cables were not sprayed with Flame-
| |
| 'astic. Inside both 4160V and 480V switch gear room, it.
| |
| was observed some cable trays-vere completely sprayed with Flamem'astic fire retardent while others were not. The licensee did not have an explanation for the difference.
| |
| I (c) The Diesel Generator building was inspected. All cables
| |
| ~
| |
| into and out of the building are run in conduit. No open raceways or trays are used.
| |
| (d} Control Rod Drive Rooms were examined. One tray of control cables in the Unit 3 control rod drive room did not have a fire stop (e) Cable trays entering and exiting the auxiliary building were examined. Four large cable trays enter the auxiliary building above the main corridor doors. The cables and trays are sprayed with Plameastic 71A for a distance of about 2 feet inside and outside. the wall.but the trays do not have fire stops. Those cable trays exiting the auxiliary building did not have fire stop> installed.

| 1 IE Rpt. "Ho's. 50-'250'/75-'7 I-3 and 50-251/75-7 (f) The cable spreading room was examined. All cables and trays Xn the room are sprayed with Flamemastic fire retardant.
| |
| All fire stops where raceways enter and leave the room were in good condition. Other ductwork in the cable spreading room such as air conditioning ducts were sprayed with Flame-mastic fire retardant.
| |
| : 4. "Maintenanc'e and Modification Procedures The inspector concluded ifrom observation and -discussions that prior to .the recent severe fire at a nuclear plant that FPL did not have a maintenance and modification procedure which specifically addressed breaching of firestops. The licensee has recently approved a pro-
| |
| ~ cedure entitled "Fire Stop and Cable 'Tray Fire Proofing". The pro-cedure names the Superintendent-Maintenance as the cognizant manage-ment member to 'authorize breaching a fire stop. The procedure fur-ther defines the construction details of the fire stop design to be usede
| |
| : 5. Site Ie~eectioe The details of examination of the cable'rays fire stops are dis-cussed in item 3, above. In discussions with the licensee, the
| |
| 'inspector was informed that major program of examining and re-working all 'firestops was und'erway. It is the licensee's intent to build fire stops on all entries and exits without regard to safety or non-safety related equipment,. The licensee further stated that t';ey intend to replace the transite fire stop material with "Marinite" because of its improved resistance to moisture uptake, and to spray cables with fire retardant a distance of 8 feet where practical rather than the two feet shown'n Figures 1 and 2.
| |
| : 6. Material Specifications for Fire Sto s The licensee uses Flamemastic 71A, fiberglass, transite, and Marinite in construction of the firestops. The licensee procures these materials by tradename. The inspector concluded from specifications provided to the licensee by the vendors, and from copies of tests of the materials conducted by FPL and independent testing agencies that the materials of construction are flame. retardant and will not of themselves support combustion.

Licensee Actions on.EEB's 75-04 and 75-04A The subject bulletins required the licensee t'o evaluate certain fire protection measures and protection from events which might occur as a result of a fire. The licensee responded to these bulletins on April 23, 1975. The licensee concluded..in his response that their
| |
| 'policies, plans, procedures 'and sys'tems provided the required con-trol and protection. During the inspection, the response was dis-cussed with members of 'FPL,management. /he,inspector stated, that the response did not contain sufficient information to permit a reasonable evaluation by the HRC that the utilities conclusions were justified. The licensee agreed to prepare a supplemental report which would contain a listing of the procedures and other documentation supporting their position. The inspector accepted a supplemental report submittal date of June 27, 1975.

| : 3. Sur FSAR and Construction Snecifications Section 8.2 of the Surry FSAR states that cable tray construction shall have approved fire stops in both the horizontal and vertical runs. Facility construction specifications for tray installation do say, that fire stops will be used, however, construction prints do not show the details of the stops utilized. Neither reference specifically addresses the compartment boundary fire stops on .electrical cables.
| |
| I The only docu entaticn that shows the fire stops utilized at Surry is a memorandum containing generalized sketches of the stops to use at Surry and a recommended procedure for installing the stops. 'these sketches show the details of two types of pressure seals and/or fire stops as described below:
| |
| ao Sleeves containing cables Two notched pennies made of one eighth inch thick "micarta" (or steel) shall be inserted in each sleeve approximately one and one half inches apart. The void between the two pennies will be filled with "Thiokol" potting compound. The vo'id between the outer penny and the "bakelite" bushing will be filled with duct seal (no dimension given). Duct seal will be used to seal around edges of the pennies and c bles and penny edges.
| |
| Two, one eighth inch coatings of "Flamemastic 71A Sprayable" will be placed over the outside surface of the sleeve opening. Two, one eighth inch coats. of "Flamemastic 71A Sprayable" will be placed on the inside penny from the other side of the. sleeve. On vertical sleeves only one bottom "penny" needs to be used to contain "Thiokol" potting compound and,fire retardant need only be applied to one side of the stop.
| |
| : b. Sleeves containing no cables These sleeves shall be sealed using solid threaded metal sleeve inserts. Two,. one eighth inch coats shall be sprayed on the outer surface of the sleeve inserts.
| |
| Co Fire stops for cable trays This type of stop is utilized for cable trays penetrating fire walls. Asbestos wool insulation is placed in the penetration around the cables and between two, one quarter inch steel plates, one on each side of the wall, bolted to the wall, loosely fit around the cables, Duct seal is packed in and around the cables approximately for two inches inside each steel plate Two, one eighth inch coats of "Flamemastic 71A Sprayable" shall be applied over the duct seal and efforts made to apply the "Flamemastic" in and around the cables within the tray close to the fire stop. The sketch shows a one eighth inch coating of "Flamemastic 71A" spray coating to be applied to both the top and bottom of the cables approximately six .feet back from the fire stop on one side.

| : 4. Ins ections of Fire Stops An inspection was conducted to verify that fire stops were constructed as described in paragraph 3 above. Since construction prints did not specify where the stops were to be located, the inspector reviewed compartmental walls which contained electrical safety related cables all penetrating the walls and electrical cables pqnetrating areas where safety related cables -wepe located. There are two types of penetrations used at Surry. One type utilizes a c"rbon steel circular sleeve embedded in the concrete with "bakelite" bushings threaded into each end to prevent cutting of the cables. The other type penetration is a rectangular opening in the concrete wall or floor to facilitate penetration of cable trays.
| |
| The following variations in the actual construction of fire stops with the design described in paragraph 3 were noted.
| |
| : a. Rela Room (Sur 1)
| |
| (1) There are a number of horizontal sleeve type penetrations from the relay room to the cable vault. These penetrations are packed with duct seal on the relay room side with no fire
| |
| , retardant applied. These 'penetrations do have "Flamemastic" on cable vault side. Several new cables have been pulled through one penetration, and the penetiation has been sealed, however, "Flamemastic" has not been applied. The "Flare-mastic" on the cable vault side extends back from the seal approximately fifteen inches.
| |
| (2) Examined twenty, 6 inch penetrations from the relay room
| |
| 'to the cable tunnel. These penetrations are packed with
| |
| .duct seal on the relay room side with no fire retardant applied on relay room side. These penetrations do have "Flamemastic" on the cables on the cable tunnel side approxi-mately fifteen inches back from the seal.
| |
| : b. Emer encv Switchgear Roo@ (Surr 1)
| |
| (1) There are a'umber of six inch sleeve penetrations from the energency switchgear room to the cable tunnel. Examined approximately one half of these penetrations and they appear to,be constructed as described in paragraph 3a. Flamemastic"
| |
| ,has been applied four or five inches back on the cables, "Flamemastic" has been applied from the cable tunnel side approximately 'fifteen inches back on the cables. Two of the penetrations observed appear to have new cables pulled through them. "Flamemastic" has not been reapplied to these cables.
| |
| | |
| EE Rpt. Nos. 50-280/75-7 l-4 and 50-281/75-6 (2) There are six penetrations on the west wall of emergency switchgear room into duct lines. The cables entering these penetrations are packed with duct seal. No "Flamemastic" has been applied.
| |
| (3) There are a number of veitical sleeve type penetrations from the emergency switchgear room to the control room.
| |
| These penetrations contain instrument and control cables to the reactor instrument panel and to the reactor console.
| |
| These penetrations are packed with duct seal from the bottom and an insulating material, "vermiculite," is applied from the control .room side.. The floor is fifteen inches thick (concrete) with a nine inch trench in the area of the sleeves. This trench is filled with the insulating material described above.
| |
| Co Cable Vault (Sur 1)
| |
| Sixteen horizontal trays penetrate the cable vault from the cable tunnel. The fire stops in this area appear to be constructed as described in paragraph 3c, however, 'lamemastic" has only been applied on the ca'oles approximately six inches from the wall instead of six feet as described on the construction sketch.
| |
| Four of the trays contain newly pulled cables. Duct seal has been packed around the cables, however, "Flamemastic".
| |
| has not been applied.
| |
| (2) There are a number of horizontal sleeve type penetrations from the cable vault to the safeguards building. The cables are sprayed with "Flamemastic" from the cable vault side.
| |
| Duct seal has been applied from the safeguards building side, however, "Flamemastic" has not been applied from the safeguards building side of the wall.
| |
| One penetration to the safeguards building contains new
| |
| 'cables. Duct seal has been applied around the cables, however, a fire retardant has not been applied.
| |
| (3) There. is one wall penetration of the type described in
| |
| 'aragraph 3c from the cable vault to the auxiliary building.
| |
| Fire retardant has been applied from the cable vault side, however, it has only been applied about six inches on the cables. "Plamemastic" has not been applied from the auxiliary building side.
| |
| | |
| IE Rpt. Nos. 50-280/75-7 I-.5 and 50-281/75-6 Several new cables have been pulled through the penetrations described above. Duct seal has been applied, however, fire retardant has not been applied.
| |
| (4) There are a number of horizontal sleeve penetrations from the cable vault to the auxiliary building. These cables are coated with "Flamemastic". for about 15 inches from the seal on the cable vault side. They are sealed with duct seal from the auxiliary building side. "Plamem'astic" has been applied .from the auxiliary building side.
| |
| : d. Cable S readin Room Above Control Room (Surr 1)
| |
| Q) There are approximately fifteen vertical cable penetrations of the type described in paragraph 3c from the -cable tunnel to the cable spreading room. "Flamemastic" has been applied to the penetration on the spreading room side and up on cables about 2 inches. The electrical maintenance personnel indicate that below the "Plamemastic" is asbestos wool and duct seal.
| |
| One new cable has been installed through one of the penetrations, however, no fire retard'ant has been applied.
| |
| (2) Cables through the ceiling penetrations from the cable spreading room to the main switchgear room have duct seal packed around the cables from "the cable spreading room side.
| |
| No'ire retardant has been applied. The penetrations enter the high voltage switchgear cubicles in the main switchgear
| |
| .room. The high voltage switchgear cubicles were not opened, therefore, the inspector did not observe the tops of the penetrations.
| |
| : e. Main Switch ear Room (Surr 1 and 2)
| |
| The main commhrcial power feeders enter this area from the turbine area. These penetrations are provided with the type of penetration described in paragraph 3c. "Plamemastic" has been applied on the cables approximately one foot from the penetrations.

| |
| (4) There are a number of vertical sleeve penetrations from the-emergency switchgear room to the control room. These pene-trations are sealed with duct seal fr'om the bottom and an insulating material from the top as described in paragraph 4b(3) for Unit No. 1.
| |
| : h. Cable Vault (Surr 2)
| |
| There are sixteen horizontal tray penetrations from'the cable tunnel and these appear to be constructed as described in
| |
| .paragraph 3c of this report. The "Flamemastic" is applied on the cables about six inches from the seal.
| |
| (2) The penetrations from the cable vault into the auxiliary building are the same as described for Unit No. I in paragraph 4c(3) and 4c(4). Xt was apparent that several penetrations were being repaired during the inspection.
| |
| (3) The penetrations from the cable vault into the safeguards building are the same as described for Unit No. 1 in paragraph 4c(2).

| |
| -duct seal. It was difficult to observe these penetrations from the bottom side because of inaccessibility.
| |
| (2). There are a number of vertical sleeve penetrations from the cable spreading room to the main switchgear room.
| |
| These penetrations are coated with "Flamemastic" back about five inches on the cables. Several new cables have been pulled through two penetrations and the cables packed
| |
| :with duct seal. "Flamemastic" has not been reapplied on these cables.
| |
| (3) Cables through the floor vertica1 sleeve penetrations to the control room are the same as described for Unit No. 1 in paragraph 4d(3).
| |
| : 5. Modifications (Surrv 1 and 2)
| |
| A number of modifications have been made involving pulling of new cables through fire walls between the control room, emergency switch-gear room, cable tunnel, cable vault, 'uxiliary building, saf eguards
| |
| ~- building', and the cable spreading room above the control room.
| |
| a.
| |
| these modifications are as follow's:
| |
| between Units 1 and 2 to provide an I
| |
| Addition of cross-tie lines and-associated motor operated valves Some'f additional suction line for each safety injection system.
| |
| : b. Addition of cross-tie lines and associated motor operated valves between Units 1 and 2 auxiliary feedwater systems to provide an additional steam generator water source.
| |
| : c. 'ddition of two booster pumps and piping between the underground condensate tank and the suction side of the auxiliary feedwater pumps for each unit to provide an additional ~ater supply to the auxiliary feedwater systems.
| |
| Addition of orifices in each 'steam generator blowdown line to provide a signal for closing the .blowdown trip valves on high flow conditions.
| |
| : e. Relocation of the solenoids which operate the main steam trip valves to an area which is not subject to steam atmosphere.
| |
| : f. Interlocking of accumulator valves. (Surry 1)

| | |
| IE Rpt. Dos. 50-280/75-7 I-8 and 50-281/75-6
| |
| : g. Interlocking of Residual Heat Removal System valves The corrective maintenance procedures for replacement of safety related high voltage power cables and for replacement of safety related low voltage control cables were reviewed for the above modifications and no provisions were incorporated in the procedures for the breaching of compartmental fire stops or repair of the fire stops to insure that integrity of the stops are maintained. For instance, the above described, "
| |
| modifications involved pulling approximately 120 new cables. Approximately one half of these cables were pulled through fire stops. Cable pulling
| |
| ,procedures do not include provisions for quality control inspections to insure that proper materials are used and to insure that repair is made as designated by the procedure. VEPCO representatives stated that the cable pulling procedures will.be revised to include instructions for repairing the fire stops and inspecting them during and subsequent to repair.
| |
| : 6. Fire Stoo Construction (Sur 1 aad 2)
| |
| The fire stops were originally installed on the cabIe penetrations by Stone and Mebster Engineering Corporation. Host of the cables involved with modifications were pulled by Richardson and wayland Electrical Contractors. The work was acco..plished by use of a VEPCO approved maintenance procedure and the cable routings were approved by the VEPCO electrical n inten nce supervisor. Althou h cables were pulled by electrical contractors, they were under direct control of VEPCO site management.
| |
| : a. Fire Stop Naterials Originally the fire stops were constructed of asbestos wool, duct seal, "Thiokol" potting co pound, "micarta" pennies, "vermiculite" insulating material, steel sheets, and "Flamemastic 71A" fireproofing material. The purchase of these materials was handled by the contractor who procured them from electrical suppliers, Purchase orders and material specifications were unavailable except for a technical bulletin which describes the fire retardant characteristics of "Flamemastic 71A" and acceptable methods of applying the "Flamemastic."
| |
| (1) "Flamemastic 71A" is produced by Dnya-Therm Corporation 1
| |
| and the fire resistance characteristics are described on Dyna-Therm Technical Bulletin 01079, Issue 2. The bulletin specifies no burn-through of one sixteenth of an inch coating after fifteen minute exposure to a propane torch, flame temperature, 2050 F with the distance from Oz the torch of two inches. The chemical composition or the fire retardant characteristics available.'

VEFCO is currently using a comparable material, "PRC" potting compound. The documentation was not available on the chemical composition or fire character-
| |
| . istics of this material. This material is being used as a sealant and is type PR-1201-Q produced by Product Research Corporation.
| |
| (3) Duct seal Procurement documentation was not available.
| |
| A .product known as "Dux seal" ape NSG, produced by Johns Manville Coxporation is currently being used at Surry. The fire retardant characteristics were not available, however, i.t is being used as a sealant.
| |
| (4) "Micarta" board was used in the sleeve type penetrations to contain the potting compound. "Micarta" is a hard fiber like material. Documentation on the chemical composition or fire retardant characteristics of this material was not available.
| |
| (5) Asbestos wool is an insulating material. Documentation on the chemical composition or fire retardant characteristics of this material was not available.
| |
| (6) "Virmiculite" is an insulating material. Documentation on the chemical composition or fire etardant characteristics
| |
| ~
| |
| of this material was not available. Sample of material .
| |
| would not burn when a torch-was applied for a short period of time.
| |
| : 7. Licensee Action
| |
| : a. Licensee representatives stated that plans axe underway to test the types of fire stops used at Surry to insure that they will effectively, stop a fire.
| |
| : b. Original material and inspection records will be obtained to verify original construction. If these records are not available, tests will be conducted on samples of installed materials to qualify the materials to above described tests.
| |
| : c. Station cable pulling procedures will be updated to include fire stop repair and inspection.
| |
| : d. Inspection of the fire stops will be completed and a repair program established to upgrade them to the standards qualified in the above described tests..

| 3.. C'o'rr'elation Between the Facility's Re uirements and As-Built Status for Pire Stops on Electrical Safety-Related Cables and Penetration Sea' Re uirements The in-pector found no applicable requirements for fire barriers and penetration seals in the Final Hazards Summary Report. He requested all site documentation related to the installation of fire barriers and penetration seals. Specifications EI-5045, Revision-3,, 1028, and 1029 were provided the inspector for,.h'is'eview. Fire barriers were not addressed in these sp'ecificati~ns. No construction and installation speci-fications for the cable ducts, were available.
| |
| The licensee had identified all penetrations and electrical equipment on prints 138002-1, 138003-1, 138384-3.6, 138732-10, 138733-6, 138734-28/29, 140937-3, 141176-6, and 141536-4 and these were reviewed and utilized by the inspector for his Observations.
| |
| | |
| Observations (1) Nuclear Service Buildin All cables were contained within heavy gauge metal ducts; where these ducts penetrated walls or floors, there was .a duct-to-concrete seal that appeared to be mortar.
| |
| i Cables entering .equipment were channeled through either metal troughs or conduits. All floor-entry conduits and troughs had fiberglass packing at the upper end. Fiber-glass had also been packed into the upper end of troughs that entered cubicles through the top of the cubicle. Ex-tensive use of asbestos wrapping within the cubicles was noted.
| |
| (2) Su erheater Buildin~
| |
| All duct penetrations had concrete-to-duct mortar seals.
| |
| Approximately S0% of the conduit penetrations had concrete-to-conduit mortar seals. Nine of the unsealed conduits passed through two floor sleeves into the control room at the west wall. Thirteen other conduits passed through a fiberglass-packed rectangular penetration in the control tunnel east wall. The other unsealed penetrations con-tained single conduit.
| |
| All control-room-equipment penetrations were through the floors of the cubicles.. These penetrations were packed with fiberglas or covered with a marinite board and had Flamemastic applied from both sides.
| |
| Elsewhere in the building, cubicle-floor-entry conduits were packed with fiberglass and sufficient evidence was available.to determine 'that troughs entering cubicle tops were fiberglass packed.
| |
| Extensive asbestos wrapping of cables and the installation of smoke detectors within virtually all cubicles was noted.
| |
| (3) Diesel Generator Room Conduits are used exclusively within this room. The penetrations to the electrical tunnel do not have {nor are required to have) fiberglass packing or sealing.
| |
| | |
| (4) Electrical Tunnel
| |
| ~J.l cables are contained within enclosed heavy-gage metal ducts. Vhere these ducts penetrate walls, there is a concrete-to-duct seal. The exception is the cable that enters the Diesel Room, which is enclosed in conduit.
| |
| In addition to a water-deluge system, this area is pro-vided with ionization and smoke-detector>> systems.
| |
| (5) General Extensive use of asbestos wrapping on cables within cubicles was noted.
| |
| The licensee stated that in excess of 80% of the facility's cables were lead-wrapped and all cable insulation was fire-.
| |

| |
| : a. Plant Status The plant was in power operation during the inspection.
| |
| : b. ;Pur ose of Ins ection The purpose of this inspection was to examine the documented facility requirements for fire stops on safety-related cables and penetration seals, to visuaj,ly inspect these items for conformance vith the requirements,'o examine the licensee's provisions for invoking the requirements during maintenance and modification work and to determine the status of the licensee's efforts with respect to the actions listed in IE Bulletins 75-04 and 75-04A.
| |
| : 3. 'Correlation Between the Facility's Requirements and As-Built Status for Fire Stops or. Electrical Safet -Related Cables and Penetration Seals
| |
| : a. Re uirements (1) The'inspector read a letter from the original Architect/
| |
| Engineer, Stone and Vebster, dated April 30, 1975, stating there vere no construction specifications prepared for the Connecticuit Yankee plant.
| |
| (2) The only specific reference to cable penetrations to be found was on a Stone and liebster drawing number 10899-FE-38A, Note 2, which stated the following:
| |
| | |
| ~ ~
| |
| ,"Upon .completion of cable installation through floor sleeves, fill voids with a.sealing compound to a depth of not less than two inches, spares to be plugged."
| |
| This applies only to the control console penetrations.
| |
| There is a detail drawing of a typical penetration con-sisting of a conduit sleeve "with coupling nuts on each end. The assembly is placed with the long axis vertical through'the concrete floor.
| |
| (3) Cable flame barr'iers are not addressed in the FSAR.
| |
| t (4) There are no requirements'for fire retardant coatings.
| |
| ,,b. 'Observations The following areas were inspected and the results are as indic'ated:
| |
| ,(1) Control Room The cables pass through conduit sleeves in the floor of the main control console as described in 3.a. above. The older penetrations were packed with an asbestos fiber material and a binding agent. The more recent sealings had been made with a flamemastic putty. All penetrations in the console were sealed as per drawing 10899-FE-38A.
| |
| (2) 'Switch Gear Room This room is located below the control room. 1fost cables from the control console pass directly into this room except for a few which pentrate outside the room and are brought through the wall in 9 cable trays. %%ere these cable trays pass through the wall there are no flame barriers.
| |
| The east wall has seven vertical cable trays penetrating the floor with no flame bar"iers.
| |
| The cable trays have metal covers installed over their full lengths. This is typical throughout the plant except in several areas where maintenance is in progress.
| |
| | |
| 0 (3) Screen House All cabling in the screen house is in conduit. The motor control centers have large openings through the bottoms to allow entrance of the conduit. These openings are not sealed.
| |
| (4) 'Emer enc Diesel Generators.A and B
| |
| .,All cable p'enetrations.in to the Emergency Diesel Generator rooms are through the walls. The 4160 volt power cables are
| |
| ,all in conduit, while the control cabling, transits the wall in conduit sleeves and into cable trays.
| |
| (5) Cable Tra Area This area is located below the switch gear room and is approxiamtely 60 ft. by 100 ft. This area is criss-crossed with cable trays and conduits. The cables drop through the switch gear room floor in conduit sleeves.
| |
| Not all of the penetrations were accessible but it was noted that 'approxi"... tely 75% of those observed were packed with a Flamemastic type compound. The remaining 25% were also in conduit sleeves but without the packing.
| |
| (6) Liaste Gas/Liauid Buildin This is a recently costructed modification (Reference Details, Paragraph 4). The cable penetrations that pass through the walls were of two types, (a) solid conduit, (b) conduit 'sleeves packed with Flamemastic.
| |
| (7) Primar Auxilar Buildin Certain areas of this building were inaccessible due to radiation. There are cable trays with covers and where the cabling leaves the trays it transitions to conduit.
| |
| The. High and'ow Pressure Safety En]ection pump cables are both made in conduit runs. The Residual Heat Removal pumps have cable tray runs to a wall which then transfer to conduit for " vertical run to the motor.
| |
| | |
| 0 (8) Cable Vault This is adjacent to the Primary containment and is the penetration point for cabling into containment. 'There are five undergound-conduit groups that enter the vault and transfer to cable tr'ays with covers. The vault has a carbon dioxide fire suppression system.
| |
| (9) Smoke Detection System I I
| |
| . Area smoke detectors were observed in the following areas:
| |
| 'Sw'itch'gear room, cable tray area,'cable vault and emergency Diesel room.
| |
| (10)Acct.dent Prevention annual The plant has a "Accident Prevention Hanual" which outlines the cordon fire safety recommendations to. the employees.
| |
| The control of welding and firewatches is addressed in detai.l in the plant Station Order S-A-3, dated 2/12/74 and S-N-212.
| |
| : 4. ''Invokement of Facility Re uirements for. Fire Stons on Electrical Safet Related Cables and Penetrations in Haintenance and ~fodificstion Procedures Flame barriers are not addressed in r.aintenance procedures but the
| |
| 'ast major modification procedure, Haste Handling System iiodification, J. 0. 11726.19, does specify zlame barriers through walls and zloors for cable and tray penetrat'ions. The cabling used was specified to be fire resistant.
| |
| : 5. 'tatus of Licensee's Efforts re lE Bulletins 75-04 and 75-04A The licensee stated that there was no additional information, con-cerning the referenced Bulletins 75-04 and 75-04A, available at except that presented in the letter response, dated April 23, 1975.

| |
| (1) Floors and Halls Fire Stops on cable trays through electrical blockouts in the floors and wallsconsist of grouting in position after cables and covers are installed. The area around the cables i" then sealed with approximately 3 inches of
| |
| | |
| Kaowool and a. 3/8 inch coat of Flamemastic 71A on each end of the penetration. On floor penetrations, Pearlite is added r to fill the Vermiculite'or area between the end seals.
| |
| Conduits are sealed by grouting in place after installation..
| |
| Spare'conduits are plugged on both ends.
| |
| (2) Floor of the Control Room
| |
| $ Iireways and conduits passing. through the control room floor are sealed by cutting a piece of 1/2 inch Marinite 36A to fit around the.wireways and conduits. The Marinite is then attached to the underside of the floor and covered, with 3/8 inch layer of Flamemastic 71A. The blockout is then filled with Vermiculite. The upper surface is then sealed with a 1/2" piece of Marinite'6A and covered with 3/8 inch of Flamemastic 71A.
| |
| The ends of the wireways and conduits in the control room are filled with 1/4 inch of Flamemastic 71A'.
| |
| : b. Observations All electrical blockouts, with the exception of the Let Down Heat Exchanger Room, due to high radiation levels, were in-spec'ted for compliance with the facility's requirements.

Invokement of Facilit Re uiremants for Fire Stops on Electrical Safet -Related Cables and Penetration Seals in Haintenan'ca and Modification Procedures The licensee currently subcontracts all maintenance and modifica-tions to electrical cables and penetration seals for Units 1 and 2 to the Architect-Engineer. The modifica'tions are then completed
| |
| ,in accordance with the requirements of tha'A-E's specification (6750-E-.406 Revision 6). The modifications were inspected to verify the fir'e stops and penetration seals were installed in accordance with these specifications. No descrapancies were noted.
| |
| The licensee is writing a maintenance procedure to be utilized in modifications involving remov .1 and replacement of fire stops and penetration seals which will include the requirements of the A-E specifications and provisions of ANSI 45.2.4. This procedure will be utilized when the licensee takes over maintenance in this area.
| |
| : 5. Unresolved Items
| |
| : a. Cable ull ro es During this inspection it was noted that many fire stops had cable pull ropes (hemp) passing through the fire stops.
| |
| Tha presence of these ropes was not noted in the specifica-tions and the licensee was asked to evaluate their presence and its effect upon the function of tha fire stop.
| |
| The licensee, at tha exit meeting, indicated the cable pull ropes would be removed and the fire stops repaired; or, where it was desirable to have tha ropes left in place, they would be cut back close to tha fire stop and their ends would be covered with Flamemastic 71A.

| |
| : b. Shrinka e/settlin of Flamemastic 71A During this inspection it was noted that the Flamemastic 71A had pulled away from many .tray covers, leaving a space of about 1/4 inch across the top of the stop. This space was apparently formed by the Flamemastic 71A settling or shrinking du'ring the drying process.
| |
| The licensee was asked to 'evaluate the presence of this space on the effectiveness of the fire stop and to take appropriate action based upon this evaluation.
| |
| This item is unresolved pending completion of the licensee's evaluation and possible corrective actions, and their subse-quent review by an HRC inspector,

| |
| : a. Re uirements I
| |
| The inspector requested the original installation specifica-tions for cabling for the, construction of the plant. Th plant personnel produced, "Technical Specification, Electrical Work, Unit //1 R. E. Ginna Nuclear Pot;er Plant, Rochester Gas and Electric Corporation, SP5451," dated October 20, 1967 for the inspector's review. The inspector found in Paragraph 4.26.17, "Installation of cables hhere entrance is made by the constructor, into pressurized rooms or into Class I struc-tures, for conduit or cables...these openings shall be suit-ably sealed...hhere cables extend through floors a fire stop of fiberglass matting...shall be installed in the trays. This also applies to all circuits into the main control panel."
| |
| The inspector found the following statement in Paragraph 8.2.2, Station Distribution System, General Cable Considera-tions, Ginna Unit No. 1, FSAR, Page 8.26C, dated January 1969:.
| |
| "Fire barriers are used at cable trays and cable runs where they enter or leave a Class I area. There will be fire barriers where the cable trays enter the relay room, auxiliary building, and where vertical trays pass through floor openings."
| |
| Class I structures as defined by the Ginna, FSAR include the following areas:
| |
| (1) Containment.*
| |
| (2) Intermediate Building.
| |
| (3) Auxiliary Building.
| |
| (4) Control Room.
| |
| (5) Diesel Generator Room.
| |
| (6) Screen llouse.
| |
| (7) Spent: Fuel Pit (8) Fuel Transfer Tube.*
| |
| (9) Containment Crane.*
| |
| * Outside the scope of the inspection.
| |
| | |
| There are no p lant re uirements for fire-retardant coatings The plant does have specifications for the procurement of fire-resistant cable.
| |
| : b. Observations The inspector observed the following areas to the requirements of Paragraph 3.a of this report with the conditions found as noted.
| |
| (1) cantrol Room (
| |
| The penetrations go through the floor to the relay room via short, open sections of conduit set in the concrete.
| |
| The cables enter the conduits and the void spaces around the cables are packed with a fiberglass type material.
| |
| All instrument and control cabinets were inspected and several were found with the packing material lying be-side the penetration. There was a considerable amount of maintenance being performed to account for some of them not being packed.
| |
| A cable tray passing through the north wall was found not to have a flame barrier. The majority of the cables come from the control room, which is directly above, and the penetrations were inspected from there.
| |
| (3) Emer enc Hatter. Rooms 1A and 1H Cable penetrations through the east and west walls of Battery Room lA were found not to have flame barriers.
| |
| (4) Control Room Air Handlin Room This room is directly below the relay room and carries
| |
| ~
| |
| a large number of cables to the cable tunnel from the relay room. This is a vertical penetration, with evi-dence of work in progress, which accounts for the flame barrier being disturbed.
| |
| (5) Cable Tunnel The cable tunnel is "T" shaped and connects the inter-mediate building, auxiliary building, and the relay
| |
| | |
| 4
| |
| ~ <<7m room through the control room air handling room end of the tunnel that enters the CRAH is protected (CRAII).'he by a'lame barrier but the intermediate and auxiliary buildings (which are epsentially directly connected, as evidenced by the considerable air flow through the tunnel) are not protected by flame barriers at their entrances to the cable tunnel. This tunnel is protected by a water sprinkler and smoke detection system.
| |
| (6) Intermediate Buildin The intermediate building is divided into "controlled" .
| |
| and "uncontrolled" sections. There is a vertical cable tray that passes through several floors by the elevator and has no flame barrier material installed. There is a pene'tration through the wall into the water treatment room with no flame barrier. Both of these are located in the "uncontrolled" section.
| |
| (7) Diesel Generator Rooms (DGR)
| |
| (a) DGR "A" There is a room directly beneath the DGR .
| |
| through which the generator cables and pass. The cables penetrate the ceiling of control'ables this room (floor of DGR). The cables coming from the motor control cen'ter "1II" have flame barrier material, while those of the relay cabinet do not.
| |
| (b) DGR "B" The same arrangement of rooms and cables
| |
| 'xist for DGR "B" and none of these had flame bar-rier material.
| |
| (8) Screen House Cabling penetrates the southeast wall by the stairs and contains no flame barrier material. Several electrical cabinets are located within'he screen house but were inaccessible for inspection. Safeguard cabinets 17 and 18 were inspected and found to have no flame barrier material where the cabling penetrates the floor.
| |
| (9) S ent I'uel Pit (SFP)
| |
| The access door from the intermediate building to the SFP has a cable tray above the door'without a flame barrier.
| |
| | |
| (10) Auxiliar 'Buildin Xn the auxiliary building there are cable penetrations leaving through the east- wall at the intermediate level with no flame barrier material.
| |
| There are several motor control centers and assorted electrical panels in the auxiliary building which were inaccessible for'nspection. Those that were accessible contained no flame barrier material for cables passing through the floors.
| |
| The lack of flame barrier material in the relay room, the cable tunnel entering the. auxiliary bu'lding, the intermediate building, the screen house, the spent fuel pit, and the auxil-iary building is apparently contrary to the FSAR commitment as stated in Paragraph '3 above. The inspector could not as-
| |
| 'certain if this lack of flame barrier material in the penetra-tions'esulted from modifications in which flame barrier material was deemed to be not safety-related and, therefore, deleted.
| |
| This item is considered unresolved, pending t'e completion of the licensee's review action per 10 CFR 50.59 and a subsequent review by an hRC inspector of the licensee's review and any modification action.
| |
| : 4. Xnvokement of Facility Requirements for Fire Stops on Electrical Safet -Related Cables and Penetration Seals in Naintena'nce and
| |
| >fodification Procedures The inspector did not find any specific requirements. for the main-tenance of flame barriers during routine maintenance and no evi-dence that it is addressed in modification instructions.
| |
| This item is considered unresolved, pending the completion of the licensee's review action per 10 CFR 50.59 and a subsequent review by an NRC inspector of the licensee's review and an; additional procedural documentation that he prepares relative to maintenance and modification of safety-related cable penetration seals.
| |
| 5.'tatus of Licensee's Efforts re IE Bulletins 75-Oli and 75-04A The licensee indicated that approximately 75% of the procedures review required by the bulletins were completed at this time.

| '3. Correlation Between the Facility's Re uirements and As-Built Status for Fire Sto s on Safety-Related Electrical Cables and Penetration Seals Re uirements on Cables and Penetrations (1) FSAR and Technical S ecification Reouirements Sealed penetrations are required for containment integrity in the reactor building (secondary containment) walls.
| |
| Xsolation required for 4160 volt dual emergency circuits includes a firewall between the switchgear; physical separation of bus sections, feeders, power centers and motor control centers; and enclosure of feeders to vital equipment in rigid steel conduit.
| |
| | |
| (2) Other Requirements Insulation on power cables and control cables Gas stated to be self-extinguishing material (either GE VULKE"E or PLA>1INOL brand).
| |
| : b. Observations (1) . Acce table Areas Visual examination of the electrical cable trays, conduits and penetration seals verified the correlation between as-
| |
| .built construction and the above requirements, as follows:
| |
| Control room floor penetrations were examined, and 769+
| |
| appeared to be sealed. Two others were found not sealed and.the licensee sealed them before the completion of the inspection.
| |
| 'The licensee stated that nine others, that could not be examined because of physical location, were sealed.
| |
| Except fnr a few unused thimbles closod off bv steel discs and plastic bushings, the control room penetrations appeared to be sealed by a (dry) mineral wool-"- packing material.
| |
| Reactor building (secondary contain,ent) wall and roof penetrations were examined. All 167*
| |
| * electrical conduits and spare thimble penetrations identified cable'rays, appeared to be sealed (described below); The licensee stated that a typical cable tray:penetration seal was:
| |
| (a) (Original application) two injections were made (inner and outer seal) of pourable Kaowool which hardened in place.
| |
| (b) Periodic leak testing and resealing resulted in the additional application of one or more of:
| |
| Pourable Kaowool or similar material Dry packed Kaowool or similar mineral woo1 Duxseal Isofoam

| |
| | |
| Inspection of the 4160 volt ducts and switchgear" verified that isolation was provided as described by paragraph 3.a. (1).
| |
| Inspection of the emergency diesel generator rooms and cables verified that isolation was provided and there was a concrete wall between the diesel generators and between
| |
| .the two control panels.
| |
| Fire-fighting equipment was visible. As an example a fire-hose and portable fire extinguishers were available near the entrance to the cable room.
| |
| Thy lower bays of the turbine building were equipped with automatic overhead sprinklers.
| |
| Insulation on power cables and control cables was examined on a sampling basis and was identified as either GE VULKENE or FLQfINOL, on each sample.
| |
| : 4. S ecific Areas of Concern re Penetration Sealin The inspector examined a combination storage/cable pulling room containing 25 cable trays, 67 rigid conduits and 14 non-'rigid~
| |
| conduits. Areas connecting"-* .to this room included:
| |
| Main cable room (openings 5X5 and 5X3 ft)
| |
| Pipe tunnel (opening 4X4 ft) 460 volt distribution room (opening 2X4 ft)
| |
| DC battery room (tunnel 5X6 ft)
| |
| The main cable room also has openings to an equipment room above the control room (a pipe chase opening, 2X10 ft, partly filled by ventilation ducts, conduits, pipes, etc.) and to the turbine building (nine cable trays through a corridor).
| |
| The inspector found that there were no cable-penetration fire stops. 'he licensee stated there was no requirement to provide cable fire stops, or to close up or seal the "bove openings.
| |
| : b. Combustible Seal Material The licensee's review of fire stops and seals following issuance of IE Bulletins 75-04 and 75-04A apparently identified Isofoam
| |
| * Greenfield type
| |
| +* Estimated sizes of openings follow
| |
| | |
| as combustible. The licensee removed' piece of Isofoam from an electrical penetration seal. It was ignited and burned completely.
| |
| The licensee statec that the Isofoam was at most only an inch or two thick and did not extend from one side of the seal to the other; thus propagation of fire through a seal was stated to be unlikely.
| |
| No test data were'vailable that would substantiate the licensee's position on flame resistance of seals. The licensee stated that there was no requirement to remove or coat over the Isofoam.
| |
| : c. Fire Retardant Coatin No fire retardant coating was evident and the licensee did not commit to apply such coatings to electrical cables or penetration
| |
| .seals.
| |
| : d. 'atter Room Cable Run I
| |
| All electrical cables supplied from battery room DC distribution panels A and B are collected into a single cable tray.
| |
| The licensee stated that the specifications do not require isolation of these cables.
| |
| : e. Fire Sto s Seals and Closures of Penetrations in Turbine Bu ldinn.
| |
| E ui ment Buildin and Reactor Building Interior 4'alls and Floors
| |
| .Turbine building, equipment building and reactor building interior wall and floor penetrations were examined where electrical cable trays, conduits and spare thimbles pass through. Typically, no seal or closure of these penetrations was evident. (No requirement was identified to seal or close the openings identified.)
| |
| The above items a through e are considered to be unresolved pending completion of the licensee's follow-up on IE Bulletin No. 75-04A'nd a subsequent review of their actions by an NRC inspector.
| |
| : 5. Invokement of Facility Requirements for Fire Stops on Electrical Safet -Related Cables and Penetration Seals in Maintenance and Modification Procedures Job orders are used to initiate work on cables, fire stops and penetration seals. The licensee's supervision controls the work to

| be done, states what procedures are to be used, supervises work as it progresses, and accepts the completed job. However, no maintenance or modification procedures for penetration seals were provided by the licensee.
| |
| This item is 'considered to be unresolved pending completion of the licensee's review of their procedures as a part of the licensee's response to IE Bulletin No. 75-04A (Details, Paragraph 6) and sub-sequent review of their findings and actions by an NRC inspector.

| Observations The inspector visually inspected all safety-'related cable penetrations, except those which could not be examined without interfering with the operation of the facility or removing material and equipment previously installed. Floors, walls and ceilings were examined in the following areas:
| |
| 'urbine Building (300'levation) Reactor Building wall sleeves (277'levation) Reactor Building wall sleeves Battery Rooms Control Room (261'levation) Reactor Building wall sleeves Auxiliary Control Room Battery Power Board Rooms Diesel Generator Rooms Diesel'enerator Board Rooms (250'levation) Cable Room Reactor Building wall sleeves Reactor Building duct banks
| |
| | |
| 0 Reactor Building (340'levation)
| |
| (318'levation)
| |
| .(301'levation)
| |
| (281,'levation)
| |
| (261'levation)
| |
| The inspector found that the installation of cable penetra-tion seals and fire stops was generally in accordance with the licensee's 'commitments in the Safety Analysis Report and with the plant's construction specifications. Exceptions which were observed were: I (1) Auxiliary Control Room, two safety related penetrations through the floor require the Flamastic coating.
| |
| (2) Cable Room, one new penetration outside of the cable room requires a Flamastic coating. Two new penetrations inside the cable room require.a Flamastic coating.
| |
| (3) Turbine Building, one Reactor Buiding Penetration ll-c, A-1) penetration'(250'levation} was not sealed with Duxseal. The inspector verified that this penetration was sealed within the Peactor Building.
| |
| (4) Reactor Building, several penetrations through the floor at various levels were not.sealed with Duxseal. These were:
| |
| SL 318 i)12 11A SL 318 M12 11B SL 281 H4 14A SL 281 Q11 6B All of these penetrations are within the reactor building.
| |
| Licensee representatives noted these findings and initiated action to correct these items. Full corrective action could not be accomplished during the inspection because of the need to procure material.
| |
| The inspector noted that the cable leaving control room panels to the auxiliary control room pass .thorugh seventy-four openings below those panels. According to design these penetrations are open.
| |
| | |
| The inspector also noted that the pull ropes have been left in reactor building penetrations at thd 250'levation of the .
| |
| Turbine Building. This does n'ot appear to- be in accordance
| |
| . with the installation specifications.
| |
| : 4. Envokement of Facilit Re uiremcnts for Fire Sto s'on Electrical Safet -Related Cables and.Penetration Seals in Vmintenance and Hodification Procedures The 1'icensee has no maintenance or modi'fication procedures relating to 'penetration seals.

| |
| ao Re uirements on Cables and Penetrations (l) FSAR and Technical S ecification Re uirements Sealed penetrations are required for c'ontainment integrity in the reactor building (secondary containment) walls. No detailed specifications were provided for electrical pene-tration seals.
| |
| | |
| The licensee stated* that one or more of the Zol1owing are used to seal electrical'penetrations:
| |
| Hard setting,sealant** inside trays and conduits.
| |
| Duct seal,= alone or with other sealants.
| |
| Polystyiene blocks used with duct seal.
| |
| Conduit bushing and a steel disc, on unused sleeves.
| |
| ~ Steel pipe plugs.
| |
| Separation of certain redundant systems, including Reactor Protection Systems RPS I and RPS II electrical cables, is required.
| |
| Metal clad ducts and switchgear are required for 4160 volt power circuits.
| |
| (2) Additional Re uirements The licensee stated plans to develop a satisfactory seal and to seal all penetrations of the control room floor.
| |
| The iollowup report on Bulletin No. 75-04A, due to IE:I no later than June 1, 1975 is to state requirements being determined by the licensee's review of such matters.
| |
| : b. Observations (1) Acce table Areas Visual examination of the electrical cable trays, conduits and penetration seals verified the correlation between as-built construction and the requirements, stated above, as follows:
| |
| Reactor building (secondary containment) wall penetrations were examined. All 160 electrical cable trays, conduits and spare thimble penetrations identified appeared to be sealed.
| |
| * Licensee's letter to XE:I dated April 17, 1975.
| |
| ** Typically Grouse-Hinds "Chico A" sealing compound.
| |
| | |
| Turbine building, equipment building, .and reactor building interior wall and floor penetrations weie examined where trays, condui>s and spare thimbles pass through. Typically no seal, or closure of these penetrations was evident. No requirement was identified to seal or close these openings.
| |
| Visual examination of 95 trays and conduits that penetrate
| |
| ~
| |
| the cable vault walls verified that all 28 penetrating secondary containment were sealed. ,No other sealed
| |
| ~
| |
| penetrations were identified in the cable vault walls.
| |
| I
| |
| '' Except'or york described to be in progress and incomplete, all the cable vault cabling was in m tal covered trays (non-ventilated). -A few raised covers, removed covers, and exposed cables were seen (estimated to be below one percent of the total).
| |
| Trays labelled S-1 or S-2 (safety system cables) were
| |
| . separated by a fire barrier* wherever one passed over the other.
| |
| . A wall separated the NPC-1 cable vault from the hPC-2 cable vault. Some apparently incomplete penetrations were evident.
| |
| The licensee stated that these will be completed and sealed or closed up.
| |
| A thermal fire alarm system was provided in the cable vault.
| |
| CARDOX fire suppression system controls as well as a port-able extinguisher and a fire hose were provided near the entrance to the cable vault.
| |
| Znspection of power cabling and switchgear verified that required fire barriers were provided and that:
| |
| 4160-volt cables were segregated from lower voltage cables and were in metal ducts or conduits.
| |
| 460-volt cables were segregated from cables operated at higher or lover voltages.
| |
| Separate conduits were used'Xor cabling to the diesel engine driven and the gas turbine driven emergency generators.
| |
| The barrier was a composition board covered with an asbestos cover on two sides.
| |
| | |
| (2) S ecific *Penetration Questions (a) Control Room Floor Penetrations Visual examination of 568 control room floor penetrations showed that duct seal was visible on 481, a drypacked miner'al wool seal material was visible on 6, and no seal was visible on 81 penetrations. The licensee stated that study of possible techniques and procedures to seal these penetrations was being performed and their resolution of this matter would be reported to IE:I.
| |
| (b) Floor 0 eninps in the Cable Vault An approximately 3 ft. by 8 ft. floor grating and other openings were evident in the cable vault. The ventilation rate was estimated (by the inspector) at about 5,000 cfm passing through these openings.
| |
| (c) Flame Retardant Coatin on Cables No flame retardant coating was evident, and the licensee did not commit to apply'uch coating to electrical cables or penetrations.'he above items (a), (b), and (c) are considered to be unresolved pending a review b'y an hRC inspector upon com-pletion of the licensee's followup on IE Bulletin 75-04A, which includes a review of such matters by the licensee.
| |
| : 4. Licensee's Procedures for Maintenance and Modifications to Fire Sto s and Seals Job orders are used to initiate work on cables,- fire stops, and penetration seals. The licensee's supervision controls the work to be done, states what procedures are to be used, supervises work as it progresses, and accepts the completed job.
| |
| No detailed written procedures were identified during this inspection.
| |
| This item is considered to be unresolved, pending a review by an NRC inspector, upon completion of the licensee's review of his procedures as a 'part of the response to IE Bulletin 75-04A.

| |
| 'or Fire Stops on Electrical Safety-Related Cables and Penetration Seals The inspector. revieved the licensee's Final Safety Analysis Report to determine vhat require...ents vere established for fire stops. The FSAR in Section 8.3.7.7, states that "Fire stops are provided around trays and in sleeves vhich penetrate areas vhere carbon
| |
| ,dioxide protection is used." The FSAR lists the C02 protected
| |
| ~,
| |
| | |
| I areas outside reactor containment as the Cable Vault, both Outer Containnent Penetration Rooms, and both Cable Tray Rooms.
| |
| .The inspector requested all construction specifications and other applicable documentation 'related to facility requirements for fire stops or safety related cables and penetration seals.
| |
| The licensee provided copies of communications bet~ een he and his architect-engineer and copies of engineering drawings showing conduit sleeves and cable runs. The communications in-dicated that the architect-engineer suggested the use of the following construction'echniques:
| |
| (1) Use duct seal (putty-like compound} to seal corduits in the Control Room for the purpose of containing breathing air .
| |
| (2) Use duct seal to contain CO2 in C02 protected areas.
| |
| (3) Use Plamemastic 71A to make a fire stop in. conduit sleeves.
| |
| ("Principal fire barriers" specifically mentioned were (a}
| |
| the walls of the Switchgear and Control Room areas, and (b) the walls and floors of the Cable Tray Room, Reactor Con-tainment NCC, and the Reactor Containment Outer Penetration Rooms..)
| |
| There is no requirement for the application of fire-retardant coatings on safety-related cables.
| |
| : b. Observations The inspector visually inspected all accessible safety-related cable penetrations in the following areas:

| |
| (1) 4'all Penetrations 11, .20, and .21 in the Protected Cable Tray Room were observed to be con:posed of a combination of Flamenastic 71A and duct seal. The seals were not all effective since air vas noted to be passing fron> the tuxbine hall into the Protected Cable Tray Boo:n.
| |

| floor penetration in the lover the boundary seal-removed.
| |
| (4) Seventeen Reactor Containment floor penetrations in the Control- Room ViCC Room were not sealed.
| |
| (5) The licensee did not intend or atten:pt to seal conduit sleeves safety-related povex and'ontrol cables between the 'arrying Protected Svitchgear Room and the Protected Cable, Tray Room, and between the upper and lover Reactor Containment PCC Rooms.
| |
| (6) Tvo conduits between the Cable Vault and the lover level of the Primary Auxiliary Building were not sealed. The inspector could not readily determine if all conduits that were 'not sealed in'he Cable Vault {~ 400) vere sealed on the opposite end.
| |
| The licensee stated that he intends to consider these issues in his efforts related to XE Bulletins 75-04 and 75-04A. These items are unresolved pending EE:I evaluation of =the licensee's Bulletin response and of any subseque'nt action that the licensee takes.

Pur ose of Ins ection Th'e purpose of this inspection was'o examine the documented facili.ty requirements for fire stops on safety-related cables and penetration seal , to visually inspect these items for conformance with the requirements, to examine the licensee's provisions for invoking tne requirements during maintenance and modification work and to determine the status of the licensee's efforts with respect to the actions listed in IE Bulletins 75-04 and 75-04A.
| |
| : 3. ''Correlation Between the Facilit 's Requirements and As-Built Status for 'Fire Sto s on Electrical Safet -Related Cables and Penetration Seals The inspector reviewed the licensee's Final Safety Analysis Report.
| |
| In response to NRC Question 7.6.d, page Q 7.6.(d) 1, which asks, in part: "Please discuss your criteria with respect to fire stops....
| |
| during design and installation," the licensee stated: "Firestops are provided where cable trays pass through walls and floors, and enter switch'gear or other equipment. Three 'types of firestops are used according to the function of the cable in the tray (control, power, etc.) and ventilation requirements of the areas involved. The first type of firestop is used in trays containing control cables passing through walls, floors, or into equipment where an* air seal is not required. It is composed to two aluminasilica ceramic fiber
| |
| | |
| blankets, 36 inches long, laid in'he tray and compressed around the cables using a cable tray cover. An ignited cable is extin-guished, by thi's firestop .because the ceramic fiber blanl et cuts off'he oxygen supply. The blanket has a low thermal conducti- .
| |
| vity and can. be used at temperatures up to 2300oF, without show-ing any g iysical,change. Even beyond that temperature, it still retains its 'fire preventive characteristics.
| |
| "Because of its low thermal conductivity and the fact that it covers three feet of cable surface area, this blanket cannot-be used .with power cables, which dissipate considerable amounts of heat. Xn addition,.it cannot easily be.inytalled in control -trays, where an air seal of the wall or floor .opening is required for
| |
| 'ventilation purposes. The firestop used for these configurations consist basically of (1) a transite sheet, to substantially close the opening, (2) Flamemastic '71A Hastic sprayed on the cab'les 6" on either side of this sheet, and (3) Flamemastic 71A ~hstic trowelled into the cable tray on top of the cables to seal any remaining air passage bet'en rooms. Flamemastic 71A has re-cently been accepted and used by a number of uti.lities for this purpose. It is non-toxic, not damaging to cable insulation, and requires no.derating of cables when applied over a one-foot section. Tests by various power companies and cable manufacturers
| |
| ..have'horn that a 1/16" coating of Flamemastic 71A will not burn through after 15 minutes exposure to a propane torch at 2050 F.-
| |
| "The third type of fircstop is used only for openings in the floor where control or power cables enter switchgear, motor control centers, supervisory cabinets', or other equipment from the tray below. This configuration combines packed fiberglass with 1/0" coating of Flamemastic 71A sprayed on either side of the closure . It provides both protection and separation of cables as they pass through the floor. This 'type of fire stop is used where control cables enter the panel in the contro1 .room."
| |
| The inspector requested all construction specifications and other applicable documents related to the installation of fire barriers and penetration seals. Specification "Indian Point No. 2 - Reactor Protection and Engineered Safety Feature Installation Criteria,"
| |
| dated 11/18/69 and Print >>o. 9321-F-3107-1 were provided to the inspector for his review.
| |
| The specification and print requirements complied wi'th the FSAR commitments. In certain instances, the specification requirements
| |
| 'exceeded FSAR commitments: (1) Troughs entering equipment cubicles from the top and conduits entering cubicles form the bottom should be packed with fiberglass from the topside after the cable is pulledi and (2) only cable jacketed in fire-retardant insulation shall be procured for facility use.
| |
| | |
| The licensee identified all penetrations and electrical equipment on prints 9321-F-2503-9, 2510-16, 3052-16, 3059-11, 3060-18, 3063-18, 3081-19, 3089-28., 3107-4, 7054-12 and H-2250. These were reviewed and utilized by the inspector for his observations,
| |
| : b. Observations (1) Frimar Auxiliar Buildin The cable and conduit floor penetrations in the Hotor-Control-Center cabinets were packed with fiberglass and vere sealed with Flamemastic., as required. i I
| |
| Other penetrations in the building were Flamemastic sealed and appeared to meet the transite sheet or fiberglass packing requirements, as applicable.
| |
| The splice boxes were Flamemastic sealed, where required.
| |
| Conduit passing through openings in walls or floor generally did not have the air spaces packed with blocking or sealing material. The licensee stated that a determination had been made that this vas not necessary and was therefore, not made a requirement. This condition was co.,~on throughout the facility.
| |
| (2) Control Buildin All floor penetrations entering equipment in the Control Room were sealed with Flamemastic, and sufficient evidence of fiberglass existed so that a determination cou'd be made that packing had been accomplished per requirements; Other penetrations in the building vere sealed with Flamem>astic and appeared to meet the transite sheet or fiberglass packing re-quirements.
| |
| Cables from trays entered equipment cubicles, sucha as the 480 V.
| |
| Switchgear, through a connecting trough or conduit.
| |
| All bottom entz'y conduits were packed with fiberglass and suffi-cient evidence existed to ascertain that this was also accompli-shed for top entry troughs.
| |
| (3) Diesel-Generator Room Conduits are =used exclusively within this room. The penetrations to the electrical tunnel, originally constructed for Unit 81, are not required to have fiberglass packing or sealing.
| |
| | |
| (4) Electrical Tunnel Host of the cables are contained within open tiays; nuclear instrumentation cable is enclosed in conduit. Hhere these trays and conduit penetrate walls, there is a transite sheet and Flamemastic seal. ,The cable that- enters the Diesel-Generator Room is enclosed in a conduit.
| |
| In addition to a water-deluge system, this area is provided with ionization and smoke-detector systems.
| |
| (5) General
| |
| . Extensive use of asbestos wrapping on cables within cubic'les, as required by the specification, was noted. Flamemastic has been applied to both sides of penetrations; the FSAR commit-ment was for such application on only one side.
| |
| The inspector reviewed purchase order/requisition numbers 05952, 05971, i'-36189, 6035, and .invoice numbers 7029, 7083, 7145, 7462, and 7481. The required fire-barrier material was purchased and delivered to the site during the construction
| |
| =period. Pages one through fix'e of "Tr,.cer Cable-Redundant Syst: em" check-sheets were reviewed by the inspector; This record indicated that spot inspections were performed to ascertain that a complete routing was to design requirements.
| |
| In the areas examined, the inspector noted that all non-safety related cables were protected with fire barriers in a fashion similar to that utilized for safety-related cables.
| |
| : 4. Invokement of Facilit Requirements for Fire Sto s'n Electrical Safct -Related Cables and Penetration Seals in >hintenance and Hodification Procedures The inspector reviewed Station Administrative Order No. 104-
| |
| ''Haintenance l~ork Request (~iGK) Procedure," and No. 127, "Hodifications to Indian Point Facilities." They require work instructions and provide control for maintenance and modification activities.
| |
| An instance of transite-barrier replacement occurred prior to the
| |
| 'specific requirements established by these proce'dures. The activity was controlled under a maintenance work request procedure and documented on HMR 85N0485. The licensee stated construction specifications and prints were utilized as work instructions.
| |
| | |
| 5~ Status of Licensee's Efforts re IE Bulle'tins~ 75-04 and 75-04A The insp'ector requested a status report from the licensee regarding IE Bulletins i5-04 and 75-04A. The licen ee provided the inspector .

The purpose of this inspection was to examine the documented facility requirements for fire stops on safety-related cables and penetration seals, to visually inspect these items for-conformance with the requirements, to examine the licensee's provisions for invoking the requirements during maintenance and modification work and to determine the status of the
| |

| |
| : 3. Corrdlation Between the Facility's Re uirements and As-Built
| |
| 'Status for Fire Stops on Electrical Safet -Related Cables and
| |
| 'Penetration Seals less' The inspector reviewed the licensee's Final Safety Analysis Report. On response to this NRC question (Number 7.5 on page I.2-50, dated 10/23/70): "Submit the cable installation design criteria...The discussion of cable installation criteria should include: .... Criteria with respect to fir'e stops...,"
| |
| the licensee stated:
| |
| "Fire stops are provided in vertical tray runs at floor lines ol at 10 foot intervals, whichever is "
| |
| | |
| Ol The inspector requested all construction specific actions'nd other applicable documentation related to facility requirements for fire stops on safety-related cables and penetration seals.
| |
| The licensee provided a procedure, titled, "Ebasco Services Incorporated, Vermont Yankee Nuclear Power Station, Cable Pulling, Terminating, Cable Tray, Conduit and i~larking System Procedure," dated 11/9/71. This procedure states, in a paragraph titled "Fire Barriers
| |
| <<Pire barriers are to be installed whenever a tray penetrates a floor or wall. The fire barrier shall extend along the cable tray for a minimum distance of 4 inches.
| |
| itA11 cable trays entering the cable spread room shall have fire barriers extending from the'all for a minimum distance of three feet..
| |
| <<79xe barriers are to be installed at all the control room floor penetrations. (To act as a seal against ingress of C 02 from the cable vault fire protection system.)
| |
| ~ I
| |
| 'Xn all vertical tray runs fire barriers shall be installed at reasonable intervals, say at 10 ft. spacing.
| |
| uThe fire barriers should be formed from "FLANK'fASTIC 71A" applied over fiberglass wadding. Application can be made e'ther by spray-ing or spreading with a trowel depending upon the location.
| |
| "FLQG2fASTIC 71A" is manufactured by the Dyna-Therm Corporation.
| |
| The licensee stated that this procedure was the only documentation at the site related to facility requirements for fire stops on safety-related cables and penetration seals.
| |
| Observations The inspector visually inspected all safety-related cable penetra-tions, except those which could not be examined without (1) inter-fering with the operation of the facility, or (2) removing material and equipment previously installed. Floors, walls, and ceilings were examined in the following areas: control room, cable vault, high-voltage switchgear room, reactor building (at elevations 345',
| |
| 318', 303', 280', 252', and 213'), turbine building (operating floor, ground floor, and basement), and pump house.
| |
| | |
| ~ ~
| |
| ~
| |
| The inspector found'ire barriers installed wherever safety-related cabling penetrated floors, walls, and ceilings. In the vast ma5ority of instances, the fire barrier was as described in the licensee's procedure: Flamemastic 71A applied over fiberglass wadding.
| |
| In a minority of instances, the inspector found that the licensee used Crouse-. Hinds Company's "Chico A5" sealing compound. The catalog specification for this compound states that it is "... a seal whi'ch withstands pressure several times greater than the explosion pressures met in
| |
| ~
| |
| conduit systems, stops the passage of flames, and prevents leakage of unexploded gas from hazardous to non-hazaidous areas."
| |
| In a few instances, the inspector found that the licensee used Plamemastic 71A applied over grout.
| |
| The cable trays in the cable vault aze covered, top and bottom, with sheet-metal plates. The cable vault also has a C 02 fire-suppression system. Windows from the computer room, which are normally open and vent into the cable vault, are designed to automatically close when the C 02 system is operated.
| |
| When covered cable trays pass through walls or floors, the fire barriers are normally inside the cable trays. Evidence that these barriers exist can usually be determined'y looking through louvers in the cable-tray covers or (where
| |
| -practical) by lifting the covers..
| |
| The inspec'toz found three instances where the licensee had performed some maintenance or modifications, disturbed the fire barrier, and had not repaired it:
| |
| (1) The base of a cabinet in the control room, located near the south wall, between columns 13 and 12.
| |
| (2) A floor penetration in the cable vault, located'.near the north wall> near a reactor protection motor.
| |
| (3) A wall penetration in the reactor building, seen from the catwalk above the 213'levation, penetrating the residual-heat-removal exchanger room at approximately 60 on the floor plan.
| |
| | |
| The licensee stated that all of the distrubed fire barriers would be repaired.
| |
| 4 ' Invokement of Facility Re uirements for Fire Sto s on Eleciri'cal Modification Procedures The inspector determined that, other than the Ebasco construction procedure described in Details, paragraph 3.a., the licensee did not have any maintenance or modification procedures for fire stops on electrical safety-related cables. and penetration seals. The inspector further determined that this Ebasco procedure was not designed to insure satisfactory tracking and close-out of penetration modifications such as the three instances described in Details, paragraph 3.b.
| |
| The licensee stated that'e was presently involved in a program to review methods and materials for cable-penetration sealing, and expected to complete this review by ~ofay 15,'1975. He further stated that all future penetration repairs and modifications would be handled in accordance with the procedure used to carry out design changes ("Design Changes Review and Approval," No. A.P. 032, Rev. 3, presently being revised); fol'lowing this procedure would insure satisfactory tracking and close-out of penetration modifications.
| |
| This item is considered to be unresolved, pending review by an HRC inspector of the program developed by the licensee for cable-penetration sealing and of his revi ed design-change procedure.
| |
| : 5. 'tatus of Licensee's Efforts re IE Bulletins 75-04 and 75-04A The inspector requested a status report from the licensee regarding IE Bulletins 75-04 and 75-04A. The licensee provided the inspector
| |
| . with a copy of a letter, Ho. MVY 75-43, dated April 24, 1975, from J. L. French (Xankee Atomic Electric Company) to J. P. O'Reilly (U.S.N.R.C.). This letter provides a schedule for eleven different types of surveys and reviews being conducted by the licensee in response to Bulletins 75-04 and 75-04A. The first plant surveys are scheduled for completion on 5/15/74; the final plant policy '
| |
| review is scheduled for completion on 9/30/75. '

Correlation'Between the Facilit 's Re uirements and As-Built Status for Fire Stcns on Electrical Safet -Related Cables and Penetration Seals Re uirements The inspector reviewed the licensee's FSAR, Paragraph 8.2.2.ll.b states: "Fire barriers are used at cable trays. and cable runs where they enter or leave a Class I area. There will be fire barriers where the cable trays enter the control and auxiliary buildings and where vertical trays'ass through floor openings".
| |
| | |
| A The inspector requested all construction specifications and other applicable documentation related to facility require-ments or fire barriers'n safety-related cables and penetra-tion seals. 'The inspector was provided with and reviewed Specification SP-5616, Revision 2 and Prints 4192-E-214-011, E-215-011, C-201-128, C-201-129, and S-201-121.
| |
| fire barriersI These documents describe the following types of and where they are installed:
| |
| (1) Trays penetrating metal walls: Kaowool packed, encased
| |
| ..in a rectangular sheet metal sleeve, with a marinite board on one side of the wall.
| |
| (2) Trays penetrating Class T. building (e. g., Control Build-ing and Intermediate Building): exterior concrete walls Kaowool packed, with metal covers bolted onto the angle iron which frames the exterior side of the penetration.
| |
| 'Voids under the cover to be filled with Flamemastic, without intending to provide an air seal.
| |
| (3) Trays penetrating interior walls: Kaowool packed, with the packing extending six inches from both sides of the wall, supported by the tray construction.
| |
| (4) Cable penetrations in the Control Room floor, for elec-trical equipment cubicles: Kaowool packed, with 'a Marinite board on both sides of the penetration.
| |
| (5) Vertical penetrations: Kaowool packed, and the tray pro-vided.with a cover for approximately six feet above floor level.
| |
| The licensee had identified all penetrations and electrical equipment locations on Prints 4912-E-214-014, -022, -023,
| |
| -024, -025, -026, -034, -036, -037, -038, -041, -042, -226
| |
| -105 and D-214-.035. The inspector reviewed and utilized these for his observation.
| |
| Observation (1) Auxiliar Buildin The inspector found that the fire barriers conformed'o specii ica tion requiremcn ts.
| |
| | |
| Where cables exited the building through sleeves, "Dux-seal" was used to seal the opening.'The required Harinite board fire barriers between re-dundant channels, on-elevations 281 and 295 were noted by the inspector)..
| |
| (2) Control Buildin The inspector discover'ed that the top marinite board had been omitted from the Control-Roon-Cubicle floor pene-trations. The licensee produced Engineering Change .'temo S/N 432 which permitted the penetration to have a marinite board on only the bottom side. The installation of fire barriers appeared to be acceptable.
| |
| (The inspector noted that armored cables served "the CRD strip breakers).
| |
| (3) Intermediate Buildin The fixe barrier installations appeared to conform to the requirements.
| |
| (The inspector observed the required liarinite board fire barriers between redundant channels, on elevation 295 and noted metal fire doors on the Emergency Diesel Pump Rooms) .
| |
| (4) Screenhouse The inspector found that the fire barriers conformed to requirements.
| |
| (5) General The inspector noted the occassional application of Plane-mastic on interior wall penetrations. The licensee stated this was done in certain cases to hold the Kaowool together and not for sealing purposes. /

| Tace inspector noted the general practice packi".g the penetrations, through which conduits passed, with Kao-wool. Kaowool.was also packed into conduits at their entzy point into cubicles.
| |
| i A water-deluge system is provided and protects, areas including the Cooling Tower,, Diesel-Generator, Oil Reservoir, Service Bui1ding,,Intake Screen House, Charcoal Filter, and Hea'jt'h Physics axeas.
| |
| The licensee stated that an automatic C02 fire suppres-sion system has been designed for. the cable spreading and xelay areas and preparatory work is underway.
| |
| The licensee a3so stated that no PVC jacketed cable was used inside the facility, and produced "Z1 -E!: Bill of M'aterials" that appeared to confirm that only fire-retar-
| |
| 'ant insulated cable'was purchased and used.
| |
| The 5aspectoz reviewed Purchase Orders 9459-01-63618,
| |
| -63"30, -63850, -64900, -64932, -65251, and -65279. They confirmed that the required fire-barrier material had been purchased during constzuction.

| |
| : b. Pur ose of Ins ection The purpose of this inspection was to examine the documented facility requirements for fire stops on safety-related cables and penetration seals, to visually inspect these items for conformance with the requirements, to examine the licensee's provisions for invoking the requirements during maintenance and modification work and to determine the status of the licensee's efforts with'respect to the actions listed in IE Bulletins 75-04 and 75-04A.
| |
| : 3. , Correlation Between the Facility's Requirements and As-Built Status for Fire Stops on Electrical Safet -Related Cables and Penetration Seals The information for the installation of cable trays is found on the plant drawings. An example of this can be found on plant drawing number 9699-FE-36G-. 7 which has details of specific penetration construction.
| |
| The normal penetra'tion is depicted as going from cable trays into conduit sleeves through floors and walls.
| |
| There are no requirements for flame barriers or fire retardant coatings on the drawings or in the FSAR.
| |
| &I
| |
| : b. Observations The inspector examined the following ar'eas,with the results indicated: 'W
| |
| /J (l) Control Room (a) Main Console The cables pass through slots cut in the floor. All penetrations were sealed with duct seal from above and a fiber-glass type insulation from below.
| |
| (b) Safet In ection Cabinet The penetrations are conduit sleeves through the floor. All penetrations were sealed with a fiber-glass type of insulation; (c) Control Room Walls Several cable trays pass through the floor against the walls. The fit up between the cable trays and floor was very close. The front side of the trays were covered with sheet metal while the backside (approximately 3 inches from the wall)'as open. The inspector could not ascertain if flame barrier material was installed. The licensee stated that flame barrier material was installed.
| |
| The inspector took a small sample of the fiber-glass type insulation and applied a flame to it. It would not burn.
| |
| (2) Switch Gear Room This room is directly below the main control room and all wall penetrations are either conduit or cable tray to conduit sleeves. Cable tray penetrations through the ceiling are closed with Masonite Board'nd duct seal compound.
| |
| (3) Ca'bio Tra 1louse This room is directly above 'the control room and most cabling-to-primary-containment penetrations pass through
| |
| | |
| , here. All cabling comes up. through the floor through conduit sleeves. There is no insulation material packed in these sleeves.
| |
| ..ry The reactor coolant pump leads are asbestos-cloth ~rapped for additional protection.,
| |
| (4) Primar Auxiliar Buildin All areas had the cabling enclosed in conduit except for several runs of mineral insulation cable in cable trays.
| |
| (5) Safet In ection Building All areas had the cabling enclosed in conduit. However, there is an area, "Manhole 83", which is all safety injection cabling. that transitions from underground conduits to @bort sections of unprotected cables and then back to conduits.
| |
| (6) Emer encv Diesel Generators Nos. l, 2 and 3 All cabling is enclosed in conduit. Each diesel-generator is in a separate room with interconnecting fire doors.
| |
| Screen House All cabling is enclosed in conduit.

| |
| : 5. Status of Licensee's Efforts re IE Bulletins 75-04 and 75-04A The inspector requested a status report from the licensee regarding XE Bulletins 75-04 and .75-04A. The licensee stated that a survey of the requirements of Bulletins 75-'04 and 75-04A relative to the plant has been made and an evaluation is in progress. (The licensee has mailed the NRC a letter, No. VYR 75-47, dated April 24, 1975, from J. L. French (Yankee Atomic Electric Company) to J. P. O'Reilly (U.S.N.R.C.); This letter provides a schedule for eleven different types of surveys and reviews being conducted by the licensee in response to Bulletins 75-04 and 75-04A. The first plant surveys are scheduled for completion on 5/15/75; the final plant policy review is scheduled for completion on 9/30/75.)

| This letter is in response to your letter to the District dated July 8, 1975 which requested additional xnformation regarding the subject inspection r'eport.
| |
| In our response to the inspection report, dated June 30, 1975, we indicated that carrective action had been taken with regard to five of the six noted discrepancies. We believe that, with the exception of the two cable trays within the reactor drywell, we are in full compliance with the cable separa-tion criteria. We believe that a physical inspection of the reactor drywell is required to determine a proposed solution to the remaining discrepancy, and therefore, are planning to complete such inspection during the outage necessary to effect a repair of the in-core instrument tube vibration problem, tentatively scheduled for October, 1975. ~0 WJ We believe that further non-compliazrce in this area is effectively precluded by our requirement of strict adherence to the procedural controls governing design changes to the facility.

| |
| | |
| ==Dear Mr. Howard:==
| |
| | |
| P This letter is in response to your letter dated May 29, 1975 which transmitted the subject inspection report.
| |
| Six discrepancies were noted in the subject report in the area of cable separation. The following corrective actions have been completed for each of the discrepancies under C. Cable Senaration:
| |
| (1) On the northeast end of the Reactor Building where a Division I and a Divisi'on II cable tray 'run vertically from the 931'-6" 903'-6" elevation to the elevation with a horizontal separation of .
| |
| approximately eight inches, a solid metal cover was installed along
| |
| . the complete length of the inside of the Division I tray. This installation satisfies the separation criteria of the FSAR.
| |
| (2) 'On the northeast corner of the Reactor Building, near the ceiling of the 903'-6" elevation, where a Division II cable tray crosses
| |
| ~
| |
| over a Division I cable tray with a vertical separation of less than eighteen inches, the solid metal cover on the bottom of the Division II cable tray was shifted during cable pulling exposing a gap in the metal barrier of approximately one inch. This gap has been closed and a solid metal barrier separates the two cable trays.
| |
| (3) On the east end of the Cable Spreading Room (918'-0" elevation), a terminal box has Division I and Division II cables leaving the box and running in cable trays which parallel each other with a horizontal separation of less than six inches for a length of about two feet. A fire barrier has been installed between these two trays by the addition of metal covers on the bottom of each tray thus completely surrounding both trays'ith a metal barrier for approximately six feet. These trays are now in accordance with the FSAR separation criteria.
| |
| | |
| 0 Mr. E. Morris Howard June 30, 1975 Page 2 (4) On the northwest corner of the Cable Spreading Room where a Division I cable tray crosses over a Division II cable tray, the metal cover over the Division. II tray was estended to five feet on each side of the cross-over area as required by the FSAR cable separation commitment.
| |
| (5) In the Auxiliary Relay Room the Division II cables from the Division II cabinet are laid in a cable tray which runs west and north and exits through the northwest area of the ceil'ing. The cable tray is installed. in such a manner that it passes within a three feet horizontal separation of the Division I cable tray which collects the cables from the Di'vision I re1ay cabinet. A vertical fire barrier approximately 30" x 40" has been installed between the two cable trays as required by the FSAR cable separation commitment.
| |
| (6) Two cable trays ring the Reactor Drywell with most of the runs being in the upper position of the 903'.-0" elevation. The trays are designated C85 (Division I) and C84 (Division II) and are run with C85 above C84 with a separation of about one foot. Evaluation of this reported discrepancy is currently in progress and we will advise your office, as soon as possible, with regard to an acceptable resolution. We would like to point out that the Reactor Drywell is currently, and will remain, inerted with nitrogen which precludes the ability of the Drywell atmosphere to support combustion.

| Docket 850-267 NRC Inspection Report 75-07 of June 19, 1975
| |
| | |
| ==Dear Mr. Howard:==
| |
| | |
| In response to the Inspection Report of June 19, 1975, concerning the audit by Mr. T.F. Uesterman during the period May 11-16, 3.975 and May 27-30, 1975 of activities authorized by NRC Operating License No. DPR-34 and pursuant to the provisions of Section 2.201, Part 2, Title 10, Code of Federal Regulation, we submit the following:
| |
| The response numbers reference the corresponding number under the appropriate heading of the audit report.
| |
| A. INFRACTIONS
| |
| : 1. The infraction stated that GAC Field Inspection Reports 4230 and 4231 documented sign-off of specific requirements which were subsquently found to be nonconforming. Field inspection Report 4230 documented that 100% inspection and acceptance of installed fire stops by the contractor QA. The fire stops and covers for the vertical river fire stop from the di'esel room had not been installed and were inadvertently signed off with FIR 4230. This was the only discrepancy noted on the rather extensive fire stop installation program. This matter has been brought to the attention of GAC and PSC has been advised by GAC that their personnel involved have been notified of the discrepancy and the consequences thereof. GAC inspection personnel have been instructed to document in detail results of inspection to avoid further infraction of this type.
| |
| | |
| Field Inspection Report 4231 was written to indicate that the specific items which had been tagged as problems by GAC Engineering and assembled into a packa'ge denoted as WA92F1863.
| |
| (No Revisions) were complete. The segregation criteria for those specific problems denoted in WA92F1863 (No Revisions) had been met utilizing zipper tubing where minimum seperation
| |
| 'riteria could not be achieved. The sign off of FIR 4231 was not intended to conclude that the bus and loop segregation problem in all tray areas was satisfactorily resolved, only those specifically denoted in WA92F1863 (No Revision). While the wording on FIR-9231 may have be'en misleading, we do not feel this to be an infraction since the specific work (WA-92-F1863) was refezred to on FIR-4231.
| |
| 2a A comprehensive inspection and evaluation is currently being conducted throughout the plant to determine the extent oi
| |
| ~
| |
| problems regarding compliance with existing separation and segregation criteria. Upon completion of this effort problem area wil1 be indentified and corrections will be applied as applicable. Discussions are'pres'ently under way,with NRC to determine an approved resolution to this matter.
| |
| 2b A comprehensive review of the cable tabulation is being con-ducted in conjunction with the present inspection and evaluation pzogram. A new cable tabulation list will be prov'ded upon completion of this work.
| |
| 2c No response required pez NRC cover letter dated June 19, 1975.
| |
| 2d Separation of control relays 9200A and 9200B which were found to be lacking in proper separation will be correction upon completion of our overall separation and segregation identifi-cation and evaluation program.
| |
| 2e The solid metal snap-on covezs for trays will be provided following the completion of the on-going separation inspection, correction and audit effort.
| |
| Due to the nature of the entire separation and segregation criteria subject, we cannot give estimated completion dates for items 2a, 2b, 2d and 2e at this time. We will keep your office advised of our progress on these matters.
| |
| We trust the foregoing information satisfactorily answers the infractions identified. If there are further questions, please advise.

| |
| Inspection Rcport 50-267/75-04)
| |
| The inspector verified, by random visual. inspection, that fire stops have been installed per Construction Specification 1-N-2 as modified by Fi.eld Change Notices (FCN) S&L 483, 479, 482, and 484. (FCN S&L 483 documented the addi+ion of vertical fire .stops. FCN's S&L 479, 482, and 484 vere added to justify material deviations from Specifi-cation 1-Ii-2).
| |
| Field Inspection Report (FIR) 4230 documented 100K inspection and acceptance of installed fire stops by contractor QA.
| |
| During the random visual in paction the inspector, in the accompanir.:cnt:
| |
| of the licensee engineering personnel (vho vere performing a concurrent inspection), found that covers for the vertical riser fire stop fro-.
| |
| the diesel rooms had not been inst:alled as stat.ed in FIR 4230. Thc riser opening through the overhead had not been sealed as required by construction droving E-54. Tive fire stop installation vas co..>>) ctcd prior to the end of this inspection.
| |
| (continued)
| |
| | |
| No furt1icr inspection of the physical installation of fire stops 4s to be peiformcd.by IE:IV; however,'nforcement action is under
| |
| , review by IE.Headquarters regarding thi item of noncompliance.
| |
| IE:IV will followup on the licensee's response to IE Bulletin 75-04/04A regarding fire stops at a subsequent inspection.
| |
| The failure to identify the incomplete diesel room fire stops as nonconforming is identified a an item of noncompliance with respect to 10 CI'R 50, Appendix B, Criterion XVI.
| |
| Seismic Desi~n of Reserve Shutdown System (
| |
| | |
| ==Reference:==
| |
| Inspection Report 50-267/75-04)
| |
| The inspector visually verified that seismic restraints and bottle racks have been installed for. the instrument panels and helium bottles associated with the Reserve Shutdown System.
| |
| The inspector was shown vendor seismic calculations (dated 5/7/75) for this modification which confirm the adequacy of the Reserve Shut'doom System during a seismic event. The licensee's engineering organization has documented their review and concurrence of the design in' memo dated 5/9/75.
| |
| Ko further inspection of this item is to be performed by IE:IV; however, enforcement action is under review by IE Headquarters for this item of noncompliance.
| |
| 7504-04 Seismic Restraints for Class I Bottles The inspector was shown calcul tions summarized by a licensee's memo dated 5/9/75, that show that the seismic adequacy has been determined for gas bottles associated with other Seismic Class I oottle racks (Helium and Hydrogen blanket gas bottles for. the surge tank , and the Helium circulator brake and seal system gas bottles). 1;o changes to these systems were indicated by the'calculations to be necessary.
| |
| Unresolved Item 7504-5 (inspection Report 50-267/75-04) is considered resolved with respect to seismic restraints for Class I. Bottles.
| |
| Corrective action is still in progre..s with respect to cable separations. Thc: insppctor, in the accompaniment of the licensee, found numerous areas within t.he auxiliary electric equipment room where the FSAR guestion 7.4(a) Separations Criteria (6 inches of separations or (continued)
| |
| | |
| asbesto zipper .cover, had not been met for both temporary. test cable'and permanent cable. In example, above panel I-368,.Loop 1, Bus 1 (orange) cable eros cd a Loop,2, Bus 2 (blue) with le..s than 6-inch separations.
| |
| An asbc tos zipper .cover had not been provided. Also, on top of the panels there was a considerable amount of cable laying together which had not been properly separated.
| |
| (2) The inspector did find that Fic1d Inspection Report FIR 4231, 'dated 5/13/75, stated that bus and loop segregation in the'ray'areas had been found satisfactory,
| |
| .,althoug>h..tl>e licensee. and inspector were continuing to identify problems. The licensee stated, with respect to -FIR 4231, that there had been no clo'scout of this item by Public Service Company of Colorado and that the inspection effort by licensee was still continuing.
| |
| The apparent improper sign-off of FIR 4231 is considered an item of noncompliance with respect to 10 CFR 50, Appendix E, Criterion Pill.
| |
| (3) The licensee estimated that an approximate 10,000 feet of asbestos zipper covering had .been in tailed during the period of April 24 oi'his a'estos, zipper through Hay 1975. The majority covering was installed to obt..in separati.ons for. cable running from the panels located in the auxi.li"ry electric room to the cable tray (above),
| |
| and from the cable trays to thc floor level of the control room (abovc).
| |
| At the exit meeting on 5/30'/75, the licensee reported that all work .had been completed in the auxiliary electric equipment room with exception of nine cables in 'the outh-east corner and some temporary cabling.
| |
| New Problem Areas (1) Nonessential/Essential Cable Separations (a) The licensee has identified that problems exist in the reactor building with re"pect .to the crossover of none"sential cables within essential trays." The FSAR,'uestion 7.4(a), states that nonessential circuit., may be routed in trays with esscnt''al circuits; hor;ever, nonesscntia3 circuits assi.gncd to segregated tray or section are required to (continued)
| |
| | |
| 4 follow thc,sc.parathion criteria for,.an esscnt,ial
| |
| 'cable in that same tray until tliey enter' control board. The magnitude .of this problein has not been determ'incd.
| |
| This 'is considered an item of noncompliance with respect to 10 CI'R 50, Appendix B, Criterion V.
| |
| The inspector found cable in the same tray of oppo'site bus or loop. had been routed using .asbe"tos zipper covering to provide separation . The I:SAI',,
| |
| Question 7.4(a), make no,provision ior this type oi routing, but requires that cable bc routed by
| |
| ,segregated trays. Jw example, in .tray 23!I2 (auxiliary clcctric equipment roon)'he 'in pcctoi counted 18 separate 'bundle of yellow color coded (loop 2, bus 1) asbe tos zippered cable . Tbe other cable in this tray was color coded blue (loop 2, bus 2).
| |
| This is considered an item of noncompliance with respect to 10 CUR 50, Appendix B, Criterion V.
| |
| The inspector also iound that for caoles routed from trays to the J wall penetrations, asbestos zipper covering ':.as been installed to.maintain separ tion of segrr".;atcd cables. The I:SAR, Question 7.4(a) and (d), pecifies thc u"e of asbestos zipper covering from the trays to the control boards located in or above the auxiliary electric equipment room and the 480 vital switch-gear room area, and within control'oards. This applies where 6 inch separation cannot be maintained. Penetration I.'P-6..frcm the auxil'"ry electric equipment room 'into the reactor was cited 0 as an example in which approximately 100 cables had been routed with zipper covering. All buses and loops pa sed through this penetration.-'he use of asbestos zipper covering from the tray to the J wall pcnctrations is'onsidered ..n unresolved item, since the PSAR doe not describe this method of cable routing.
| |
| Thr licensee has initiated an extensive audit to dcterniinc the extent of the eparation" problem with respect to nonessential/essential c"blc Gcparati ons a the licensee believes that "he majority of thc c "ble which is <<ot meeting the I'SAR', gu tion 7.4(a),
| |
| (continued)
| |
| | |
| separations,critcri'a,is,nonessential .cable.
| |
| is based on an audit that was performed in 'his 1971 by the licensee to determine the separations of essential cable and circuits.
| |
| (2) Cable Tabulation During the tracing of cable, the inspector found that a part of the control cable associated with the emergency diesel generators was not designated as essential in the Cable Tabulation listing. These cablch are as follows:.'.7.096
| |
| ...Control (Bu ..2) 7097 Standby Generator 1A and 1B Control Timer (Bus 2) 25194 Interlock Auto Sequences Programmer'or ESS Load (Bu 2) 26673 Sequence Programmer lB Control (Bus 2) 26715 Control (Bus 1/Bus 2)
| |
| Specification 1-N-2, Supplement 1, specifies that essential.
| |
| 'cables are to be designated by a hexagonal symbol in the
| |
| 'cable tabulation listing. Such identification was not evident for thc above listed cables.
| |
| The licensee seated in response to this finding, that although the C&le T"bulation appeared in error, these cables had been inspected during the 1971 audit conducted by thc licensee and. werc treated as essence:ial circuits.
| |
| .The licensee 'i.s, however, reviewing the Cable Tabulation
| |
| . List's.as part of the ongoing audit 'of the essential/
| |
| nonessential separations pr'oblcm.
| |
| ~
| |
| This is considered to bc an item of nonco.pliance with respect to 10 CFR 50, Appendix B, Criterion V.
| |
| (3) Redundant Circuits tiithin Control Boards (a) The inspector found essential redundant cable" 25590 and 25593 (color coded blue/Loop 2, Bus 2) in the save race way in panel I-10, Eay 900, with essenti"3.
| |
| '' redundant cables 25722 and 25777 (color coded orange/
| |
| Loop 1, Ms 3.), and 25724 (co'or coded yellow/'-p 2, Eus 1). This intermixing of cable was idcntificd as a failure to maintain separation of redundant in trumcnt bus power supp3.ies (Bus 1 and Bus 2).
| |
| These two buses are associated with shutdown cooling actuatioh. Thc 1SAR, Question 7.4(d) specifics (continued)
| |
| | |
| that redundant circuits'ithin control 'board" .
| |
| will be separated by a minimum of 6 inches or atherwise suitable barrier're to be provided.
| |
| Modification and rerouting of 25590 and.,25593 was accomplished prior to,the .completion of this inspection. The licensee stated that this was felt to be only an isolated case.
| |
| This is considered to be an item of noncompliance with respect to 10 CFR 50, Appendix 3, Criterion V.
| |
| I (b) The inspector found that redundan't load shading
| |
| .relays 9200A .and .9200F~ for buses 1A and 19 were setting side-by-side in panel I-66. A. barrier for separations had not been provided as specified by PSAR, Question 7.4(d).
| |
| This is, considered to be an item of noncompliance with respect to 10 Ci'R 50, Appendix 3, Criterion V.
| |
| (c) The licensee stated at the exit meeting on 5/30/75 that a 100/ audit of all control panels .s"ociatcd with"'essential circuits would be performed for all circuit changes since the licen ee's 1971 audit of essential circuit (4) Low Level Sign~); Cable Trav Covers Thc inspector found that the solid metal snap-off covers had not been installed for tray" carrying low level signal
| |
| 'cable in the 480.vital switchgear room "nd the equipment room. The CESAR, Question 7.4(a), speci-auxiliary'lectric fies that metal snap on-off covers are to be used for such trays.
| |
| The licensee stated at the exit meeting on 5/28/75 that covers will be provided following the completion of all.
| |
| ongoing inspection and corrective action.
| |
| This is considered to be an item of noncompliance with respect to 10 C1R 50, Appendix 3, Criterion V..
| |
| (continued)
| |
| | |
| ci Other Electr'cal 'Item" Di.scusse<l (1) Method .of 'Identi fvin Electrical Se >aration Def icicncies The inspector found that the licensee and contract:or personnel were identify'ng electrical separation deficiencies by tying whit:e strips of plastic flagging at each location. Documentation of flagged area'as not maintained. The inspector questioned that thi.
| |
| method provides assurance that flagged areas have been properly corrected.
| |
| The licensee stated at the e>."it meeting on 5/30/75, that a means for documenting flagged areas would be provided to assure that corrective action has been completed.
| |
| (2)'ire Sto~s The inspector questioned the pack of specific contractor.
| |
| inspection requirements to assure that repaired fire stops are properly inspected following the installation of new cable or conduit. Such worl: is performed under a contractor h'ork Authorization.
| |
| The licensee stated at the e>:it meeting of 5/30/75, that inspection requirement:s would be included as a part of the QA Inspector Checkli t performed by contractor QA personnel.

| |
| The licensee stated that a modification in the Control Pod Drives (CRD) penetration rea is being considered based on the results of B Series Testing (Sequence 1-7). The licensee stated that an apparent reverse flow of Helium up the CRD is occurring.
| |
| | |
| Post:ulated concrete temperatures in e>tcess of 250 F for power levels above 9% have been calculated. The installation of seals in th" CRQ's is currently being evaluat;ed.

| | |
| a sw<<l <<,<<, o4 w<<<<<<<<IW, w' however, the emergency fcedwatcr heacier wah maintained at 2950-psig. The emergency feedwater headc:r supplies the bacl:up bearing water system. Xn elie past, the dip in beariug water pre. sure nor>rally resulted in a circulator trip due to ehe 475 psig bearing water low pressure trip. (The lowe.st pressure recorded during current testing was 590 psig.) This ineurn normally resulted- in the trip of additional circulators due,to the. apparent interplay in the 'buffer/helium syseem (buffer/mid-buffer trip).
| |
| 'It is the licensee's intent (for present operation) that the feedwater header pressure will be maintained at 2950 psig 'mergency or greater by use of thc 8 n.otor oper ted feed pump. St ndard

| |
| The licensee acknowledged this i'nformation.
| |
| : 3. Corrective Action Review (Reference Licensee letter to Chief, Reactor Operations Branch, Region I, dated March 21, 1975)
| |
| : a. The inspector's review of corrective actions in response to Rcport 50-244/75-01 included: P
| |
| | |
| (1) record reviews, observations and discussions with licensee personnel to verify that corrective measures taken were as described in the response letter; (2) verification that appropriate management controls were invoked to avoid further occurrences; and (3) observation of posted copies of enforcement correspondence as required by 10 CFR 19.11.
| |
| : b. The following documents (by iten number) were examined for each item discussed in the licensee's response letter:
| |
| (1) A 37.0, Revision 2, "Conduct of Operations for Safety Evaluations as Related to Facility "Modifications, Special Tests or Experiments," dated March 13, 1975; (2) gC 401, Revision 5, "Control of Procurement Documents for Purchased Materials, Parts, Components and Services,"
| |
| dated March 20, 1975; (3) Audit Finding Corrective Action Report dated March 10, 1975; (4) QC 801, Revision 4, "Control of Accepted Material, Parts and Components," dated March 14, 1975; (5) (This item previously resolved in Report 50-244/75-05);
| |
| and (6) New Procedure for Removal of Ori:ginal Drawings from the File Room dated January 24, 1975.
| |
| The inspector had no further questions on the licen ee's resolution of the above items. Findings were acceptable.
| |
| : 4. Previous3 Identified Unresolved Items
| |
| : a. Feedline Vibration (Reference IE:I Report 50-244/75-09)
| |
| (1) The inspector observed readout instrumentation from LVDT's located on the feedwater piping inside contain-ment. The instrumei tation indicated pipe motion of less than 0.1 inch while the plant was at 100/ power.
| |
| The "B" feedwater pipe appeared to exhibit the most
| |
| | |
| steady -state vibration. The following criteria had been established:
| |
| (a) movement > O.l inch notify duty engineer; and (b) .movement > 0.25. inch change load.
| |
| (2) ST-75-4, Revision 1, "Turbine Plant Start-up Program Following Plant Trip of 0956 Hours on 6-1I-75," dated June 26, 1975 was completed on June 27, 1975. This pro-cedure provided for controlled power escalation above 25%, and had been successfully employed to achieve'full power operation.
| |
| (3) June 1975 Hain Steam and Feedwater Uelds Examination Final Report was reviewed. This package included liquid penetrant examination records, visual examination records, and instrument calibration records pertaining to NDE in-spections conducted in accordance with cor ~itments to the NRC documented in Report 75-09.
| |
| (4) The licensee stated that a,r'eport to the NRC including an evaluation of the vibration transient would be suo-
| |
| .mitted by July 18, 1975. dphil>>'he licensee's actions appear to be appropriate, the inspector stated that this item will remain unresolved pending a revie~ .of the li-censee's report.
| |
| The licen'see acknowledged this. information.
| |
| : b. Haintenance De ar'tment Trainin (Reference IE:I Report 50-244/75-01)
| |
| A-50.7 {Draft) "Haintenance Training Program," was reviewed.
| |
| The licensee stated that this procedure covered all Hainte-nance Department Personnel, including Instrument and Control
| |
| . technicians. The licensee stated that the draft procedure had received a PORC approval on July 14, 1975, and was'ur-rently being process d for issuance. The inspector had questions on this item. This item is resolved. no'urther C~ Chemistr and H~.alth Ph sics Procedures
| |
| {Reference IE:I Report 50-244/75-01)
| |
| (1) The inspector reviewed the following items wi'th respect to the licensee's program for upgrading the subject procedures:
| |
| | |
| (a) QC-602, Revision 8, "Plant Procedure Document Control,"
| |
| Figure 1, dated April 12, 1975; (b) Memorandum from G. Hoyt Whipple (University of Mi.chigan) dated March 1, 1975 containing comments and suggestions on .selected HP Procedures; (c) Health Physics and Chemistry Procedures; (d) Radioactivity Discharge Procedures; (e) Primary Chemistry Procedures; (f) Water Chemistry Procedures; and (g) Environmental Sampling- Procedures.
| |
| (2) The following are examples of those procedures that ap-peared to be primarily administrative in content:
| |
| (a) HP-O, "Format for Health"Physics .and Chemistry Pro'cedures," dated January 9, 1975; and (b) PC-0/WC-O, "Chemistry Procedure Usage, dated July 1, 1975.
| |
| (3) The inspector noted that contrary to the requirements of QC 602, Revision 8, dated April 12, 1975, certain ad in-istrative procedures governing safety-related activities conducted by the Chemistry and Health Physics Department appeared to have been approved for use by persons other than the PORC, QC, and Plant Superintendent.
| |
| This item is a deficiency.
| |
| (4) The inspector identified other examples of the above deficiency during a review of plant operations. Specifi-cally, Operations Standing Order A-73-1 dated February 3, 1975 describes the policy for Operations Standing Orders; although an administrative document affecting safety-related activities, it was issued for use without the required review and approval.
| |
| Inter. Office Correspondence entitled "Visitor Instructions" dated February 5, 1975 issued by the Office Supervisor to Security Force Personnel required persons to remain in the
| |
| | |
| portal'onitor for five seconds upon egress from the plant.
| |
| 'his'dministrative document had not received the required review and approval. In addition, the inspector noted that several persons observe'd at random remained in the porta3 monitor for a period considerably less than five seconds upon egress from the plant. Apparently the docu-ment.was ineffective in achieving 'the desired 'result.
| |
| The licensee acknowledged these additional examples of the above .deficiency.-
| |
| (5) The licensee prcvidcd.the following status with respect to procedure updating:
| |
| Procedures Completed as of Planned JU'1 ~
| |
| 18 3,9 75 Health Physics 35 32 Primary Chemistry 22 20 Vater Chemistry 31 31 Radioactive Discharg" Environ:-::nta3.
| |
| ll
| |
| .10 1
| |
| )U.th the exception of the Environmental area, the licensee plans to complete the remaining procedure by Octob r 1, 1975. The remaining environmental procedures are expected to be available by December 31, 1975, although this may change when new Environmental'echnical Specifications are issued.
| |
| UP Rcla Hodification (Reference IE:I Report 50-244/75-'1)
| |
| (1) The inspector reviewed the following documents with re-spect to the licensee's intended action to upgrade the 4160.volt bus relay installation:
| |
| (a) S~f 75-30 Replace existing 4 kv UF Relays with new relays on Buses llA and llB dated July 14, 1975'nd (b) the safety analysis for EDR 10GS, Revision 1, dated July 7, 1975.
| |
| | |
| (2) The licensee stated that five new replacement relays had been tested satisfactorily, four of which would be used in the installation, with the renainder placed into spares.
| |
| The inspector had no further questions in this area at this time.
| |
| This item is resolved.
| |
| : e. Chemistr Procedure Usa e The chemistry department prepared a list of complex or infre-quently accomplished analyses that will be conducted by pro-cedure. This list was included in PC-0/VC-O, Chemistry Procedure U'age," dated July 1, 1975. The inspector had no further questions on this item at this time.
| |
| I This item is resolved.
| |
| : f. Flame .Barrier In tallatio>>
| |
| (Reference Report 50-244/75-07)
| |
| (1) The licensee stated that the lack of flame barrier mate-rial in penetrations as committed in the'FDSA was not a result of modifications in which flame barrier material had been deemed not to be 'afety-related, but rather an apparent omission during construction.
| |
| Maintenance Procedure No. H-56.1, Revision 0, "Removal and Placement of Penetration Seals," dated Hay 5, 1975 provided for the placement of ceramic fiber material in accordance with the license application, as described in Engineering Specification EDR Ho. 1070, which invoked the requirements of page 8.2-6c of the Ginna Station FDSA. This maintenance activity was conpleted on May 10, 1975.
| |
| SH 75-32~ Revision 0, "Installation of Penetration Seals with BlSCO Silico>> Foam," dated Hay 5, 1975, was com-pleted on June 5, 1975. The inspector noted that the existing fire barrier material was removed prior to the installation of silicone foam in each case where the foam was installed.
| |
| (2) The inspector stated that contrary to the requirements of 10 CFR 50.59:
| |
| | |
| (a) ~ thc plant had been operated without flame barriers installed as described in the safety analysis'rcport; (b) 'prior Commission approval had not been obtained to so operate the plant; and (c) no written safety evaluation was available to indi-cate that the omission of these barriers did not constitute an unreviewed safety question.
| |
| This infraction had the potential for causing or contribut-ing to an occurrence with safety significance.
| |
| The inspector stated that the licensee's corrective actions appeared to be appropriate and no further response is con-sidered necessary at this time.
| |
| The'licensee acknowledged this information.
| |
| (3) The inspecto: stated that based on the corrective action taken in H-'..i.l and S';f 75-32, it appeared that no further action wouln be necessary as a result of this infraction.
| |
| The liccnsci acknowledged .this information.
| |
| (Reference Report 50-244/75-05)
| |
| The inspector observed that Procedures RP-42.0, 43.0, 44.0, and 45.0, Revision 1, dated June 12, 1975 in each case pro-vided for signoff verification of initial conditions.
| |
| This item is resolved.
| |
| : h. interface Controls with Desi n Contractor The inspector determined that the following procedure had been prepared to define the interface:
| |
| Review of Architect Engineer Design Docu, cnts Ginna Station dated Harch 8, 1975.
| |
| This item is resolved.
| |
| | |
| .- .13 Cor orate and Plant Desi n/Modification Interface The inspector determined that the following procedure had been
| |
| .revised to define the interface:
| |
| :Design 'Modification Control, Revision 3, dated March 26, 1975.
| |
| This itom is resolved.
| |
| *5. Review of Abnormal Occurrence Renorts
| |
| : a. Selected Abnormal Occurrences were reviewed to verify that:
| |
| (1) The cause was identified and that details were clearly reported to the NRC and facility management; (2) Corrective action described in the licensee's report was taken to prevent recurrence; (3) Each event was reviewed and evaluated as required by the Technical Specifications; and

| |
| Co During the review of AO 75-04 it was noted that the Hain Steam "Isolation Solenoid Test Valves are not treated as safety-related and their spare parts are not included in the Quality Assurance Program.
| |
| This is contrary to 10 CFR 50, Appendix B, Criterion II, and the Quality '".:.:urance Manual, Section 1.3.1.1, which states, in part:
| |
| "The quality assurance program shall apply to all activities affecting ti e safety-related functions of all existing Seismic Class I structures, systems, and components, including their foundations and supports, that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health. and safety of the public."
| |
| This item is considered to be a deficiency.
| |
| As another example, the inspector inquired about replacement parts for the Incore Flux Monitoring System to determine if they were being purchased under the QA program. PO No.
| |
| 5-ZZZ-57554 dated March 19, 1975 for a drive wheel and hub assembly was observed by the inspector to meet the QA pro-gram requirements.
| |
| d~ AO 75-10. The .isolation of the "C" Safety Injection pump from May 27 to June ll, 1975 is a violation of Technical Specification Paragraph 3.3.1.l.c.
| |
| The licensee s corrective action was judged to be unacceptable in that no method for the verification of status lights on safeguards equipment when assuming 'control board duties has

| |
| been promulgated. The licensee agreed to e tablish and imple-.
| |
| ment a mechani ".". for safeguards equipment status light verifi-cation. The in:;pector stated that this item was considered to be an infraction and will require a response from the li-censee. The licensee acknowledged this information.
| |
| : e. AO 75-11. This occurrence was in noncomplj.ance with Technical Specifi'cation paragraph 4.l.b, Table 4.1-2, bote (1). The li-censee's corrective action appears adequate and nn response
| |
| ~,.required to -this deficiency.
| |
| : f. Except ad described above, findings vere acceptable.
| |
| ge The circumstances associated vith the maintenance of two safety-related pieces of equipment were reviewed relative to Technical Specification reporting requirements. This in-c1uded the Pressurizer Power Operated Relief Valve and the Pressurizer Relief Guard Valve. Findings were acc'eptable.
| |
| : 6. Unusual Events
| |
| : a. Selected Unusual Events were reviewed to verify that:
| |
| (1) The cause vas fdentified and that details vere clearly reported to the NRC and facility management; (2) Corrective action described in the licensee's report was taken 'to prevent recurrence; (3) Each event was reviewed and evaluated as required by the Technical Specifications; and (4) Safety limits, limiting safety system settings, and limit-ing conditions for operation were not exceeded.
| |
| This review included inspection of PORC minutes, '.faintenance procedures, Station Hodification Documentation, Quality Assur-ance Records and discussion with various staff personnel.
| |
| : b. The following Unusual Events were reviewed:
| |
| (1) UE 75-1, Drop of two control rods; and 4
| |
| (2) UE 75-,2, Small leak at letdown line drain weld.
| |
| : c. Findings were acceptable.
| |
| | |
| 16 .
| |
| : 7. Startu i. Tcstin a~ The inspector reviewed the following items to determine that selected pre-critical and post-critical checks were performed in accordance, with Regulatory requirements:
| |
| (1) ,S-15.'2, Revision '2, "Flux Happing Emergency and Calibra-tion'Procedure," dated hp'ril 16, 1973, completed on July 2, 1975; (2) Startup Physics Data, (Preliminary) dated Hay 14, 1975; (3) Flux Haps V-9 through V-12 dated July 9, 1975; (4) S-15.1, 'Flux Hap V-12 dated July 1, 1975; (5) Ini'tial Design Target Hand 'with -3.6% Axial Off et dated Hay 7., 1975; and (6) Target Band with -4.5%'xial Offset issued after Flux lfap V-12 dated July 8, 1975.
| |
| : b. The'nspec'tor'oted terat the all rod out predicted boron concentration at criticality vas 1392 ~;pm and measured was 1402 ppm. Similarly, the predicted .isothermal te-,peratu e coefficient was -7.4 pcm/oF and the measured was -3.9 pcm/oF.
| |
| The inspector had no further questions in this area.
| |
| Findings vere acceptable.
| |
| : a. The inspector reviewed the following i.tems to deter'mine that selected systems disturbed or tested during the refueling outage were returned .to an operating status prior to plant startup:
| |
| (1) RSSP-ll, Revision 2, "Pressurizer Safety Valve Test 434," dated March 5, 3.975, completed April 9, 1975; (2) RSSP-7.0, Revision 3, "Control Rod Drop Test," dated September 24, 1974, completed 'fay 9, 1975; (3) CP-209, Revision 0; "Calibration of Area Honitors-Th-62 Detectors (R-l-R-9),".dated June 3, 1975, com-pleted July 9, 1975; and

| (4) CP 46l, Revisf on 0, "Calibration and /or Haintenance of Steam Generator Level Channel '461'," dated January 18, 1974~. completed hpril 6, 1975.
| |
| Findings ~ere acceptable.
| |
| : 9. Review. oi Plant 0 erations
| |
| : a. Shift Lo s and 0 eratin Records The inspector reviewed the records listed below. The review was governed by the licensee's administrative'rocedure A-20.
| |
| (1) Shift Foreman and Official Record: Entries vade for the period June 1-July 15, 1975 were reviewed. Documentation involving abnormal occurrences met the requirements of A-20.
| |
| (2) Log Book Reviews: The Official,Record and the Shift Foreman's Logs were observed to have been reviewed at least, once per week by the Operations Engineer for the period of June 1-July 15, 1975.
| |
| ~
| |
| (3) Operating Orders: The Operations Engineer Standing Orders were reviewed.
| |
| It was noted that several of these orders appeared to amplify, modify and direct plant operation.
| |
| This is contrary to Technical Specification 6.4.1 which states, in part: "The plant shall be operated and main-tained in accord:.nce with approved procedures."
| |
| The inspector noted that this practice was also incon-sistent with h'!SI N18.7-1972, which allows for standing
| |
| 'orders for "dissemination to the plant staff of instruc-tions of general and continuing applicability. to the conduct of business." Exa-.ples given included defini-tion of duties and 'filing of charts, as opposed to the actual operation of the plant. This item is a deficiency.
| |
| (4) Review of PORC Yieetinp ~itinutes The following minutes were reviewed:
| |
| | |
| (a) Meeting No. 90-75 through 98-75 from June 17 to July 3, 1975.
| |
| The inspector noted that no as-built print revisions were found necessary as a result of SM 75-35, "Modification t:o Hain Steam Isolation Valves," com-pleted June 25, 1975'.. Further review revealed that a vendor drawing used for erection had been marked up to reflect the modification and included in t: he equipment history fil The inspector noted that Step 3.6.4 of QC 303, Revision 0, Modification Control Activi.ties," dated July 1, 1975 referred to "revisions to applicable plant drawings and flow prints" as per QC 603, Revision 5, "Control of Drawings," dated March 7, 1975. The licensee pointed out that QC 603 was only applicable to system flow and circuit drawings.
| |
| The inspector noted that QC 1701, Revision 4, "Control of Quality Assurance Records," dated January 24, 1975 requires retention of records and drawing revisions t:o 'safety-related systems and components. The licensee stated that this requirement was met by QC 1704, Revision 1, "System and Equipment Hist.ories," dated December 4, 1974.
| |
| The insp. "tor had no further questions on this item at t:his t ime.
| |
| (5) Jumper (Bypass Log): Documentation for June 1-July 15, 1975, relative to the use of jumpers and lifted leads was reviewed and no bypassing discrepancies with Technical Specification requirements were observed.
| |
| : b. Tour of Accessible Areas The inspector observed operations in the Control Room and made a tour of the Auxiliary and Intermediate Buildings on July 15, 1975. The following observations. were made and these were discussed with the Shift Foreman:
| |
| (1) Honitoring Instrumentation: Hain Control Board readings were compared with local. indications for selected param-eters. No discrepancies were noted.
| |
| | |
| (2) Annunciator Alarms: The inspector observed various alarm .
| |
| indications that were received and acknowledged by the Control Room Operator on duty. These conditions vere discussed vith the Control Room Operator and the Control Room Operator was knowledgeable on the alarms and the actions required.
| |
| Shift Staffing: The inspector observed that the operating.
| |
| shift was staffed above the minimum requirements of Technical Specification Figure 6.1-2.
| |
| (4) Radiation Controls: Radiation control areas in the Auxiliary Building vere reviewed for proper posting, condition of step off pads, and disposal of Sii'P clothing.
| |
| Findings wore acceptable.
| |
| (5) Plant Housekecpin" Conditions: Storage of material and components vas observed with respect to prevention of safety and fire hazards, and no adverse conditions werc identified.
| |
| (6) Existence o Fluid Leaks: The inspector observed a leak on fcedwatc valve 4012. 'This leak was reported to the Shift Foreman. A trouble report for appropriate mainte-nance action had been initiated. The inspector had no further questions on thi" matter, at this time.
| |
| (7) Existence of Piping Vibrations: No noticeable piping vibrations 'were observed during this inspection.
| |
| ipe Hanger/Sei mic Restraints: Several pipe hangers and seismic restraints (snubbers) on safety-related systems were observed. Findings were acceptable.
| |
| (9) Valve Positions/Equipment Start Positions: The suction and discharge valves of the high pressure safety injec-tion pumps and their start switches were observed to be in accordance with Technical Specification requirements.
| |
| (10) Equipmcn'aution/Lockout Tag Information: The tag log was reviewed and thc inspec: )r that eq'uipmcnt under tag was consistent with the log << ~d entries on tagging forms (selective review) appeared'to be proper.
| |
| (ll) Plant Tour: The inspector was informed that the last tour made by the Shift Foreman occurred prier to assuming duty.
| |
| | |
| 20-During th~ inspection of operating logs it was noted that administrative controls for operating logs, with the excep-tion of the Shift Foreman Log and Official Record, do not exist.
| |
| This is contrary to 10 CFR 50, Appendix B, Criterion XVII, which states, in part: "Sufficient records shall be main-tained to furnish'evidence of activities affecting quality.
| |
| The records shall includi at least the following: Operating
| |
| ;logs and the results of reviews."
| |
| This item is a deficiency.
| |
| During the inspecto s tour of the facility a schematic dra~m on masking tape was noted to be posted at the ion exchanger operating station in the au..ili'ary building. Additionally, a handwritten procedure for the operation of the boric acid batching syst: em was posted in the auxiliary building.
| |
| The use of these unapproved procedures for pl..nt operation is anoth;r example of the deficiency discussed in 9.a(3) above.
| |
| The licensee removed the above noted schematic and procedure during the inspection. The inspector stated that other areas of the plant not covered on his tour should be addressed in the cor) ctiv>> action for this deficiency.
| |
| The licensee acknowledged this information.
| |
| The inspector observed an out-of-date calibration sticker on the external security building portal monitor (PP"f-8). The sticker indicated that the portal monitor had been calibrated in February 1974 and wa's .due for calibration in February 1975.
| |
| Upon questioning, the licensee could produce no evidence to indicate that the monitor had been calibrated. The licensee indicated that no special calibration was required; that the unit served only as a go-no go instrument, and was not criti-cal to control of radiation exposure or contamination, since another portal monitor (PifC-4) at the control point was used for this purpose.
| |
| The technical manual (P't) for. both units was reviewed. The test and calibration procedure for Hodel PPH-8 outlined volt-age tests, rate meter calibrations, and post-calibration back-ground settings. The PHC-4 TH also provided for calibrat" on of the unit.
| |
| | |
| . 21-The inspector could not locate any calibration procedures for
| |
| 'hese units and was thus un:ble to 'ascertain that they were calibrated within a period of time that would reasonably be expected to verify proper operation, including meter response time and alarm setpoint.
| |
| The inspector stated'that 'failure to calibrate the portal moni-
| |
| -tors appeared to deviate. from'enerally accepted =practice in the industry, as described in ICRU Report 20, "Radiation Pro-
| |
| -tection 'Instrumentation and its Application," issued, October 1, 1971.
| |
| The licen ee acknowledged this information.
| |
| : 10. Fuel Iutee~rie The inspector discussed with the licensee the measures taken to ensure that increasing coolant activity caused by leaking fuel would not .result in violation of Technical Specifications. Areas discussed were the licensee's previous experience with Making fuel, monitoring of trends with respect to Technical Specification Limits and the possibility of further failure causing, an early refueling.
| |
| e The inspector had no further questions in this area at thi.". time.

| Hang ement Interview A management interview was condu ted with Hessrs. Goering, Superintendent; Plant Engineering; Hunstad, Staff Zr>gineer;, and Albrecht, Electrical Engineer, at the conclusion of the inspection'n July 23, 1975. The following matters were discussed.
| |
| A, The inspector inquired into the facility's plans for a periodic testing of the fire protection system equipment and alarm. The licensee stated that this area'ould be evaluated. by September 1; 1975.
| |
| .B. The iaspector stated that the diagram of normal and alternate shutdown, cool down, boration, and =water sources, did not reference.
| |
| any procedures. 'hc licensee replied that the appropriate procedure numbers would be added to the diagram.'Paragraph 5, Report Details)
| |
| C. The present status of commitments made in response to XEB'5-04A was discussed and the licensee considexed i;t no problem to meet the stated dates.
| |
| The inspector stated that he had noted during his inspection that no repairs had boon performed on any of the boundary seals noted in the !fay 13, 1975 inspection. The licensee stated this was due to a misinterpretation and the penetration seals would be inspected, evaluated, and repaired by September. 1, 1975. (Paragraph 3, Report Details)
| |
| E. The in pector stated that in his review of thc Task Foxce recommenda-tions, an evaluation of presently ava'ilable respiratory equipment as fire fighting equipment was missing. 'The licensee stated that this evaluation would be made. He also stated that the, Task Force had not been di banded. (Paragraph 5, Report Details)

Gonyeau,.Training Supervisor 2., 'FSAR Commitments Prairie Island's FSAR- Section 8.3-7 states: Cable entrances into the control, room, x'clay room, an'd Class I areas are sealed to prevent the entrance of smoke and fire from outside sources.
| |
| 3~ Boundar Seals A .total of approximately one-half of the boundary .seals in the "control room, relay room, diesel generator rooms, bus ry~ms and applicable areas of the tur'bine and auxiliary buildings were inspected. No open penetrations were noted in the 'isually inspections. Hinor discrepancies and flamemastic seal degradation were noted as compared to the field standar'ds (procedures developed from Construction Specifications). The present condition of some seals may. allow smoke to pass but appear to .be a fire barrier.
| |
| Due to a misinterpretation of IEB-75'-04 and 75-04A the licensee had not performed any repairs on the boundary seals at the 'time of the inspection. The licensee stated that an evaluation would be made and the seals repaired as necessaxy by September 1, 1975.
| |
| The licensee representative=stated. that any changes resulting from the evaluation to the field standards (procedures used during construction) would be reported as a supplemental response to IEB-74-04A.

| |
| ; May 28, 1975 (WiK 75-50), June 24, 1975 (KlY 75-65),
| |
| and August 6, 1975 (hWZ-84)
| |
| : a. Firestop Discre ancies and Safet Evaluation As stated in the FSAR (Section 8.3.7.7), "Fire stops are '-
| |
| provided around trays and in sleeves. which penetrate areas
| |
| | |
| J where carbod dioxide protection i's used." Section 8.3.7.6 states that "Carbon dioxide discharges into and totally floods the cable vault, the penetration rooms, and the protected and unprotected'able tray rooms in the event of a fire in those areas."
| |
| The penetration room area outside the reactor containment is defined by the licensee to include both outer penetration rooms and the two (upper and lower) 1fotor Control Center Rooms directly below the penetration rooms. This area description is consistent with construction drawings FE-35A, FE-32C, FE-46G, FE-373, and FSAR Figures 5.1-1 and 5.1-2 which show communication between the subareas via floor slots (12" x 18")
| |
| and a'ircular stairway. The penetration room area as defined by the licensee was designed to simultaneously flood all subareas with C02 rather than'individually sealing off and
| |
| ,flooding the subareas (i~fCC rooms and outer penetration rooms).
| |
| The licensee requested guidance from his architect-engineer during plant construction in 1972'n what materials werd to be used as firestops. The A-E informed the licensee that Flame-mastic 71A was acceptable as firestop material out duct seal was not. (Duct seal was acceptable for barriers other than firestops.),,
| |
| The inspector stated that several items identified by him as Unresolved Items during Region I Inspection 50-309/75-07 con-stituted changes to the facility described in 'the FSAR in that certain firestops were found not to meet the above criteria.
| |
| The licensee stated that a safety evaluation in accordance 10 CFR 50.59 was not made prior to these changes. The 'ith discrepant items & additional items identified by the licen-see and the inspector subsequent to Report 50-309/75-07 are as follows:
| |
| (1) The firestops for wall Pen'etrations Protected Cable Tray Room ll, 20, and 21 in the were composed of a combination of Flamemastic 71A and duct seal. (These items were identified in Report 50-309/75-07, Detail 4(l). The inspector verified that the licensee had corrected the items by removing the duct seal and replacing it with Flamemastic 71A.)
| |
| | |
| e" 1 in the Protected (2) The firestops for wall Penetration Cable Tray Room had only asbestos rope without Flame-mastic 71A applied. (This item was identified in Report 50-309/75-07, Detail 4(2). The inspector verified that the licensee had corrected this item by applying Flame-mastic 71A.)
| |
| (3) The firestop for floor Penetration 186 had been removed.
| |
| (This item was identified in Report 50-309/75-07, Detail 4(3). The inspector verified that the licensee had cor-rected this item by applying Flamemastic 71A.)
| |
| (4) Firestops were never installed in sleeves carrying control and'ower, cables between the switchgear rooms and cable tray rooms and between the upper and lower Reactor Contain-ment HCC rooms. (This item was identified in Peport 50-309/
| |
| 75-07, Detail 4(5). The licensee perforried a safety evalua-
| |
| ,tion 'per 10 .CFR 50.59 that included the lack of these fire-stops and concluded that they need not be installed.)
| |
| (5) Two conduits between the Cable Vault and the lower lev'el of the Primary Auxiliary Building were not sealed and other Cable Vault sleeves were sealed with duct seal.
| |
| (This item was identified in Report 50-309/75'-07, Detail 4(6) and has been resolved by sealing the conduits with duct seal. The use of duct seal for. Cable Vault sleeves was reviewed in a PORC meeting on August 25 and it was determined that no unreviewed safety guestion exists due to:such use.)
| |
| (6) A,hole (~ 4" OD). rec'ently 'drilled in the wall was unsealed in the Upper ".fCC room. (This was identified during a fire-stop tour'n August 21. The hole was sealed with Flamemas-tic 71 prior,to the completion of the inspection.)
| |
| (7) A cable. tray between the Unprotected Cable Tray Room and the turbine area was not properly firestopped. (This item was resolved prior to the end of the inspection by applying Flamemastic 71A around an asbestos board.)
| |
| | |
| .iQ The inspector asked if a safety evaluation had, been made after
| |
| . the discrepancies were identified to determine if they consti-tuted an unreviewed safety question as'defined in 10 CFR 50.59 (a)(2). The licensee stated that a 10 CFR 50.59 evaluation had been made for item 2.a(4) and provided the inspector with a copy of a memo containing the evaluate.on~ Th'e licensee stated that the remaining discrepancies had been reviewed by
| |
| .plarit supervisory personnel with the conclusion that no un-reviewed safety question existed; however, the review and conclusion reached were not documented in facility records.
| |
| 'he inspector discussed the discrepancies with the Plant Superintendent, Assistant Plant Superintendent, and Assistant to the Plant Superinendent and determined from the discussion that an undocumented safety evaluation had been made. The
| |
| ; licensee stated .that a special Plant Operations Review Com-mittee meeting would be convened on Monday, August 25,, to document the evaluation. 'The inspector confirmed in a
| |
| ~
| |
| ..telephone conversation on August 25 that the PORC had per-formed a formal review per 10 CFR 50.59 and concluded that no unreviewed safety questions existed due to the firestop discrepancies.) P The inspector stated that fhilure to change or. construct the firestops as described in FSAR Section 8.3.7.7 .without having first made a safety evaluation is contrary to the provisions of 10 CFR 50.59. The inspector stated that failure to docu-ment the safety evaluation made after the firestop discrep-ancies were identified was also contr'ary to 10 CFR 50.59.
| |
| These findings constitute an Item of Noncompliance and are "considered to be an, Infraction.
| |
| b, 'icensee and Architect-En ineer Inter retation of Fireston Criteria As was mentioned under Detail 2.a above, the licensee requested guidance on firestops from his A-E in 1972 during plant'onstruc-tion. Correspondence from the A-E to .the 1icensee appears to interpret the FSAR firestop criteria as follows:
| |
| - Flamemastic 71A should be used to seal sleeves as follows:
| |
| Walls of the Switchgear Rooms.
| |
| Walls o'f the Control Room.
| |
| Walls and Floors of the Cable Tray Rooms.
| |
| Walls and Floors of the Reactor Containment MCC Rooms.
| |
| Walls and Floors of the Reactor Containment Outer Penetration Rooms.
| |
| | |
| - Floors or walls bearing on or against earth are not fire barriers.
| |
| - Sleeves carrying power and control cables between the switch-gear rooms and cable tray rooms are not required to be sealed since the'. switchgear cubicles act as a fire barrier.
| |
| The power bus ducting entering the switchgear rooms is sealed by fiberglass plate inside and Transite outside.
| |
| This guidance has since been endorsed by the plant and is being incorporated into procedure i~fYi~f-5-108, "Cable Penetration Sealing."* For barriers that are .equired to be installed for reasons other than fire, duct seal is recommended by the li-censee and 'his A-E.
| |
| The interpretations described above are consistent wit/ FSAR firestop requirements except that:
| |
| -'he above interpretations do not address the sleeves in the ceiling of the cable tray rooms, whereas the FSAR requires firestops in these sleeves. (The licensee has reviewed this practice per 10 CFR 50.59 and concluded it to besealed acceptable.
| |
| with The licensee now requires these sleeves to be duct seal.)
| |
| - The above interpretations do not address the Cable Vault"
| |
| .boundaries, whereas t.he FSAR requires sleeves in these boundaries to have firestops. (The licensee reviewed this practice per 10 CFR 50.59 in a PORC meeting on August 25 and considered it to be acceptable. The licensee now requires one end or the other of sleeves penetrating the Cable Vault to be sealed with 'either Flamemastic 71A or duct seal.}
| |
| The licensee stated that plant safety evaluations performed in accordance with 10 CFR 50.59 dealing with firestops would be discussed in the next semiannual report. The'icensee also stated that the firestop criteria for Maine Yankee will be delineated in that reoort. This is. an Unresolved Item I receipt of that report. ' pending'egion
| |
| : c. Plant Sealin Surve s The'icensee is in the process of conducting surveys of the Control Room and Cable Vault to assure that all Control Room floor penetrations are sealed with duct seal and that all Cable Vaults penetrations are sealed at one end with either duct seal or Flamemastic 71A. The surveys and associated sealing will be complete by August 29. From the inspector's revie'w of the present sealing status, the inspector concluded that the haoitability of the Control Room or the CO2 protection of the Cable Vault are not adversely affected. '
| |
| These items, originally identified in Reference (1), Details 4(4) and 4.(6), remain Unresolved Items pending completion of the licensee's surveys and sealing.
| |
| : d. Invokement of Facilit Re uirements for Firesto s
| |
| ~
| |
| The inspector reviewed. a draft procedure, MYN-5-108, "Cable Penetration Sealing," that addresses the issue of restoring firestops and boundary seals disturbed during maintenance operations. The procedure will be =approved by September 30.
| |
| The licensee has issued guidance in the form of an administra-tive directive to accomplish the* repairs necessary to m et the FSAR firestop criteria. The inspector verified by questioning of the personnel performing the repair that they were knowledge-able in the proper repair techniques.
| |
| This item, originally identified in Reference (1), Detail 5, remains an Unresolved Item pending final licensee approval of the procedure.
| |
| : e. 'valuation of Slots in Outer Penetration Room Area During a firestop survey on August 21, the inspector observed
| |
| ~
| |
| , some cables passing loosely through slots (12" x 18") between the subareas (Lower ifCC Room, the Upper HCC Room, and the Reactor Containment Outer Penetration Rooms) of the penetration room area. The cables were in trays up to the floors and after
| |
| ~
| |
| they passed through the floors but were not supported by sleeves or trays as they passed through the floors.
| |
| | |
| The inspector verified by examining construction drawings that the slots were designed in the flo'or.'he licensee could not readily produce documentation to show -t:he cable loading'of the slots. The 1'icensee stated that the slots and their cable loadings would'e reviewed by an engineer next week.
| |
| Thi's Xs an Unresolved Item pending receipt and review by the
| |
| 'inspector of additional information from the licensee.
| |
| : f. Status of Licensee's Res onse to IE Bulletins 75-04 and 75-04A The 'inspector reviewed the reports listed in Reference (4).
| |
| The licensee has been sending monthly summary reports in accord-ance. with IE Bulletin 75-04A detailing plant progress in respond-ing to the issues.set forth in IE Bulletins 75-04 and 75-04A.
| |
| . The final licensee response to the bulletins is projected-for September 30.
| |
| : 4. Inservice Ins ection Data Review A Region I inspector recently determined at another facility that an individual who was certified as a Level II UT technician was performing ultrasonic, ezaminations as a Level II (as described by SNT-TC-1A) when his,qualifications only justif-'ed him being certi-fied as a Level I.. It was determined by Region I that the same individual had performed ultrasonic ezaminations at.Haine Yankee during the recent inservice inspection program.
| |
| The,.inspector reviewed all of the raw data sheets to determine the individual in question had signed any UT examinations as a if Leve'1 II technician without having another Level II as a cosigner.
| |
| The inspector found that, with the ezception of one weld examina-tion data she'et concerning five welds on No. 1 main feedwater line, the weld records signed by, the ind vidual in question were cosigned by a valid Level II technician.
| |
| The one weld data sheet in question was signed only by the individ-ual not qualified as a Level II. Consequently, these results would not be acceptable in satisfying the licensee's inservice inspection program requirements.
| |
| The licensee stated that these tests would be repeated by appro-priately qualified personnel during the next in-service inspect'on.

| None.
| |
| Mana ement Interview A. The following subjects were discussed at the conclusion of the inspection on July 22, 1975 with Messrs. Butterfield and Jurecki.
| |
| The inspector summarized the findings of the visual inspection of penetrations. The inspector stated that several instances of failure to meet CE requirements regarding firestops and seals for electrical penetratxons had.been identified, and that this would be considered a deviation.
| |
| P The licensee s tated that the Station Nuclear Engineering Department was developing a repair schedule in response to the initial firestop inspection and the actions requested in,XE Bulletins 75-04 and 75-04A. (Paragraph 2, Report Details.
| |
| : 2. The inspector stated the combustible material had been removed
| |
| .from the Auxiliary Electric Room since the previous inspection, however combustible material was still found at various locations in 'the plant. In addition, rags found in two secondary containment penetrations during the previous inspection had not been removed.
| |
| The licensee stated that they were inspecting the plant and removing combustible materials from fire hazard areas. (Paragraph 3, Report Details) 30 The inspector stated that the item regarding cable separation.
| |
| will continue to remain unresolved pending further investigation.
| |
| (Inspection'Report 50-)0/75-9, 50-237/75-12, 50-249/75-14)
| |
| | |
| Messrs. Harpster, Little and Knop met with Mr. Palmer and other members of the Commonwealth Edison Production and Engineering sta f on August 14, 1975, to discuss Commonwealth Edison's schedule 'for installation and repair of fire stops at the Dresden, Quad-Cities and Zion stAtions.
| |
| Representatives of the, licensee stated that:
| |
| 1; Sargent,and Lundy is presently preparing drawings to be used in. the repair of deficient penqtrations and installation of firestops for penetrations not covered by existing specifications.
| |
| : 2. Advance purchase orders have been issued for ceramic fiber and flamenastic. The vendors expect no problems in meeting the delivery dates.
| |
| 30 The work package will be issued to the stations by September 2, 1975. . Materials are expected to be on site September 8, 1975. Estimated time for completion of the .work is three months.
| |
| : 4. The work'package will require a 100% audit of penetrations prior to completion of repairs to make certain that all foreign materials are removed. Repair priority will be given to the Control Room, Cable Spreading Room, etc., in accordance with the safety significance of these areas.
| |
| HRC representatives asked to be notified of any changes in this schedule and urged that this work be c'ompleted as expeditiously as possible.
