SUMMARY
((
Scope of Work l
Gage-Babcock and Associates was retained under Contract (609019 by Niagara Mohawk Corp. to perform a verification and fire hazard analysis survey of.Nine Mile Point Unit 1 Nuclear Power Station in Lycoming, New York.
" The verification survey was conducted using the Fire Protection SER dated July 26, 1979 as the base line document for Fire Protection improvement commitments to the Nuclear Regulatory Commission (NRC). Each commitment was listed and drawings and '
documentation were reviewed to assure modifications made were ;
appropriate to the NRC concern. The drawings showing the i l modification were taken to the plant and compared with the installation; any deviations from the drawings were noted.
Technical Specifications, Administrative Procedures and Admin- )
istrative Controls (Fire Brigade) were reviewed with comments nade on any discrepancies noted.
A survey was conducted to obtain information on fire loading, fire zones, fixed fire protection systems, location of safety f, related equipment and electrical cables. This information was assimilated into a separate updated Fire Hazard Analysis.
(. ~
The work did not include review of Safe Shutdown nor review of compliance with " Guidelines for Fire Protection for Nuclear Power Plants" Appendix A to BTP APCB 9.5.1. Additional work vas added to the scope with the review of fire protection improvements f or Appendix R. The review was to determine compliance with drawings, applicable codes and good practices but no determination was made as to the adequacy of improve-ments to meet Appendix R Criteria.
The following is the written scope to which the surveys were conducted.
A. Verify that NMP-1 has met all commitments contained within Fire Protection Program submittal of 2/28/77 and NRC Safety l Evaluation report dated 7/26/79 including subsequent corres-pondence af fecting these commitments.
- 1. Determine and list all commitments. Review the Fire Protection Program, the SER and the subsequent corres-ponde nce .
- 2. Evaluate adequacy of design records. For each commit-ment requiring the installation of protection features, ascertain that plans were prepared and that required

SUMMARY
OF GENERIC PROBLEMS The following is a summary of generic problems found in various areas of the plant.
Fire Doors A number of " fire door assemblies" have deficiencies which negate their fire rating or lack the proper labeling to deter-mine their fire rating. Some doors and frames in designated .
fire walls labels have dobeen not have the U.L.
modified by thelabels while others installation with the of conduit I
j through door frames, cutting doors in half to make Dutch doors and by the addition of electronic strikes. A number of sliding fire doors are not ' installed correctly and others are not the proper size for the opening being protected. j Maintenance on a number of doors is necessary due to improper- ;
latching, inoperative door closures, lack of latching mechan-isms, and physical damage to doors.
At various tines during the survey, fire doors were noted blocked open without the proper fire watch. See Appendix J for j
detailed Survey of Fire Doors. I k
l Transient Fire Loads i I
i Considerable designated fortransient storage offire loads are stored combustible in areas not materials.
In areas designated for storage where automatic fire suppression is i i
provided, the material stored extends beyond the sphere of protection.
The improperly stored items include fire retardant wood, crates, mable liquids.
cutting and welding carts, oil drums and flam-Penetration Seals i
The penetration seals on Niagara Hohawk's Drawings C-27101-C i and NiagaraC-27102-C Mohawk. were compared with a U.L. test sponsored by The comparison revealed numerous discrepancies between the drawing the- construction See AppendixofA.theSome seals tested and the seals on of the differences were not significant enough to invalidate the test results; others are sufficiently different that additional testing is warranted.
! Due to the numerous penetration seals, only a random sample of the various types (over thirty) were surveyed. The penetration

in Appendix Spec walls were all surveyed with The survey results of all but
( cable tray seals are found in' Appendix C. Of the 248 seals surveyed, 73 had problems (29.4%). See Page CIA for summary.

l A separate survey was conducted for internal conduit penetra- !
tion seals. Most of the conduit penetrations were found un- !
sealed. See Appendix E. l l
Fire Alarm System i A number of local fire alarm panels were noted to be in the trouble mode and remained in that condition for extended per-iods of time. The mark-ups on a number of panels dated back to j 1982 and others are months old.
Plant personnel believe that the elevated temperatures in a number of areas cause the local fire alarm panels to go into the trouble mode.

- 3. PENETRATION SEALS The 1979 SER commits NMPC to penetration seals equal to !
existing fire barriers. NMPC had no rated seals in the l plant prior to writing their FHA and committed to a testing l program to include existing and new penetration seal types.
IEEE Standard 634-1978 " Cable Penetration Fire Stop Quali-fication Test" was to be used as a basis for test proce-dure.
A " Test Plan and Specification for Pipe and Cable Penetra-tion Fire Stop, Qualification Tests for Existing gr Pro-( posed Pipe and Cable Penetration Fire Stop" was developed and carried through. Underwriters' Laboratories, Inc. was hired to construct and test the fire barrier assemblies.
NMPC's Quality Control inspected the U.L. f acility and NMPC personnel witnessed the tests. A letter / internal memo of 3/19/80 discussed the U.L. test program with subsequent letters discussing each of the four tests. It is in these letters that the 6 lb./cu. ft. Kaowool density was first introduced even though on review of the actual test assem-blies it is clear that this level of Kaowool fill was not consistetitly used.
A safety evaluation dated August, 1980 includes details of the U.L. tested floor penetration seals and all were based on 8 cu ./f t . A similar safety evaluation of January, 1981 based the. fill of the wall penetration seals on 6 cu./f t.
Section III discusses the test program in detail.
There are over 30 different types of penetration seals being used in the facility. Drawings C-27101-C and C-27102-C give insta3?ation details of the various floor and wall seals but do not include cable tray type penetrations.
There are both rated and .non-rated penetration seals in the pla nt . Non-rated cable tray seals are discussed under

" Cable Tray Fire Stops". ,
- 4. FIRE DOORS The Safety Evaluation Report dated July 29, 1979 required Niagara Mohawk to upgrade the fire ratings of doors and f rames in walls separating fire zones, separating safety related equipment from hazards and fire rated enclosures.
Tha rating of the doors were to be commensurate with the rating of walls in which they were installed. Most of the walls were upgraded to 3 hrs. and the doors installed in these walls were 3 hr. rated fire doors and frames. Door to stairways, battery rooms, seal oil unit are two hour
- f. ire rated.
- 5. FIRE AND HEAT BARRIERS Fire barriers are generally 3-br. fire rated walls with penetrations and doorways protected by fire rated seals and doors. These walls separate the plant into various fire zones. Fire barriers with a 2-hr. fire rating enclose stairways, battery rooms, seal oil unit and lacoratory. j These areas are located within a fire zone and the en-closing walls provide separation of critical equipment,
- enclosure of hazards and safe means of exit or egress to various floors.
Non rated barriers called " Thermal Shields" protect safety related cable trays and equipment from a fire in the Con-denser Bay (261 Level up). These walls are substantial concrete or concrete block with many penetrations not sealed with fire rated assemblies. The doorways to the area have 3-br. rated fire doors and frames but do not have the 4 inch overlap to protect the opening.
Flame shields are provided between redundant safety related equipment containing small quantities of oil or large elec-trical panels. These metal shields are to prevent direct flame impingement from one unit to the next. The shields do not protect the units from a common exposure fire.
- 6. CABLE TRAY FIRE STOPS Non-rated seals are provided at floors pierced by cable trays or cables. These seals are installed to prevent vertical propagation of flame along the cables.
Fire stops for cable trays in the horizontal are generally not provided. Fixed automatic suppression systems are in-stalled on any stack of trays three or more in height. &
Fire stops have been provided in the Reactor Building W l'.

f N between the East and West sides where cable trays pass through the " combustible free" zone.
Where cable trays and cables pass through fire rated walls or floors, a rated and non rated assembly consisting of Flamemastic 77 and Kaowool is provided. See Appendix B for analysia. .
- 7. SMOKE REMOVAL SYSTEMS l The smoke removal system for the control complex and Tur-bine building basement is designed to remove smoke and moderate heat to permit personnel entry, restore visibility a,nd evacuate products of combustion. -
The smoke vent system in the turbine building is intended !
to remove a major portion of the heat f rom the fire to help l prevent horizontal fire spread, improve conditions for )
manual fire fighting and to remove heat to preserve the unprotected steel roof structure.
The smoke removal system design is based on a minimum of 4 air changes / hour with 6 air changes / hour preferred.
The roof vents in the turbine building are based on one sq. )
- ft. of vent pe r 100 sq . f t . of floor area. This ratio was !
based on NFPA 204, 1980 criteria for a " Moderate Heat Release Content" Occupancy. See Appendix D. .1
- 8. FLAME RETARDANT MATERI ALS - CABLE TRAYS AND ELECTRIC, PANELS 1
i Flamemastic has been provided on cables in trays over .
safety related electrical panel boards. The extent of the !
flame retardant coating beyond the panel boards is depen- l dent on the number and arrangement of cable trays.
The Flamemastic is used in lieu of water suppression sys- j tems in areas with cable trays stacked three or more high.
The electrical panels with cable trays above have the tops sealed with Flamemastic to prevent firefighting water from entering the electrical panels. ;
- 9. EMERGENCY SHUTDOWN PANEL Due to the existing arrangement of safety related circuits, the utility was required to provide an emergency shutdown panel independent of the control room and auxiliary cable (j' spreading rooms. Upon further investigation of circuits, saf ety related equipment and fire zones it was determined 1^ .

- 10. EMERGENCY LIGHTING 1
Emergency lighting is provided by the AC lighting system backed-up by diesel generator and station batteries. In means of egress and areas providing access to safety re -
lated equipment, 8-hour rated battery pack lights are pro- <
j vided. Battery packs are also provided in areas uhere saf ety related equipment is actuated, or readings taken. l j

( 3. PENETRATION SEALS Due to the large number of penetration. seals, all the seals were not surveyed. Approximately ten (10) penetration seals of each . type (not including cable trays) were surveyed at random.
Over thirty (30) dif ferent types of seals are detailed on drawings C27101-C and C-27102-C. These drawings were used as the bases for inspecting the seals. On the following page is a graphic sysnopsis of the survey indicating problems with the penetration seals. Of the 248 seals surveyed, 73 had problems (29.4%). This does not include problems asssociated with con-duit or cable tray seals. For detailed findings of the survey, see Appendix C.
Part *of the verification was to compare the details of the penetration seals on drawings C-27101-C and C-27102-C with a U.L. test, File NC601, Project 79NK8678, November 17, 1980 Report on Floor and Wall Penetration Fire Stops. The test was sponsored by Niagara Mohawk and the purpose of the test was to' determine the adequacy of both existing and future penetration seals. The comparison of the Niagara Mohawk seals and the fire test is detailed in Appendix A. Along with the comparison are comments on the acceptability of the seal if modified from the fire test s pecime n .
A random survey of conduit penetrations was conducted to deter-mine the extent to which they have been sealed. The survey was done regardless of penetration type. Areas surveyed included the wall between the screenhouse and turbine building, and the Turbine Building 261' Elevation floors and walls. The survey indicated that a majority of the conduits are not sealed. For survey results, see Appendix E.
The survey of penetrations included the inspection of all cable tray seals through floors and walls and comparison with the ,
assembly tested in the U.L. penetration test. The assembly i installed at the plant was structurally different from the l assembly tested. Due to this structural difference, a compari- 1 son of seals is difficult and a retest should be investigated. I For comparison and survey results see Appendix B. j i
To determine the adequacy of the existing seals to meet.the i details required to obtain the necessary fire rating, the l installation procedure and Quality Control was investigated. i From the review one cannot be assured that the amount of cera- {
mic blanket or loose fill required by the " Installation De- l tails" were complied with. See Appendix A for the study. ;
Once the penetration seals have been installed, the seal has to i r be inspected and maintained and if a problem exists a Work s Request has to be generated. The adequacy of the surveillance 21 ,

is in question in both to the physical inspection and documen-See Appendix I .
E tation.
In summary, the surveys and studies revealed a number of prob-lems from design to verification of installation to inspection after installation. Corrective action is indicated in the various Appendices and should be initiated.

- 3. Results - A representative number of penetration seals of each type utilized in the plant were checked for compliance to installation details. Approximately 30% of the seals checked were not installed in accordance with the design detail drawings, whether the dctails depicted an acceptable seal or not.
Specifically, for seal type WP"3, only 10 to 20 seals checked >
were correctly installed or maintained. For seal type FP-3, only .
4 of 12 seals checked were correctly installed or maintained.

Satisif actory of unsatisf actory are the responses indicating the seal condition given by the inspector during the survey. The penetrations are " visually inspected to verify that they are sealed in accordance with their referenced detail." Of the 73 seals we found deficient, only one had been cited deficient in the 3/21/84 i nspection . The most alarming problem cited is that f 20 seals were incorrectly listed on the drawings and i surveillance, i.e., they were not listed in accordance with their referenced detail.
The inspection completed on 3/21/84 noted that fire watches were being instituted as a result of 63 seal deficiencies (63 Work Requests (W.R.'s) were issued). It did not note any fire patrols being issued and did not make note of any verification of detector operability . Only seven W.R.'s were marked off as done.
Sections 3.6.10.1 b and c of the Tech. Specs. state that a continuous fire watch on one side of non-functional fire barrier penetration be established within one hour or verify the operability of fire detectors on one side and establish a fire watch patrol .
Detector operability is verified by checking the fire alarm panel for trouble conditions; if none, then the last surveillance is cited as proof of operability. A fire watch patrol consists of a walk-through by a fire department member of the area affected by.
the non-functional penetration seal once every half hour.
Once the tire watch or patrol has been instituted, the W.R. 's are issued and listed on the fire department W.R. log.
Several problems exist. They ares (

- 5. The W.R. does not provide for. nor specifically state C.," whether a fire watch or patrol-is required while it is in effect.
NOTE: The issuing of a W.R. for a penetration seal does not i require a Breach Permit to be issued. As stated. earlier, the Breach Permit does state if a fire watch is required and assigned.
Summary: Fire patrols are being used extensively instead of fire watches and neither is properly documented or . controlled.

CORRECTIVE ACTION The Smoke Purge Damper D16 was repacked with 7.2 lbs of Knowool, and the retaining angle iron was reinstalled. The staff members that were involved with exceeding i the 14 days limit were reinstructed on the importance of returning equipment to l service within the Technical Specification time limitations.
ASSESSMENT OF SAFETY CONSEQUENCES There were no potential safety consequences arising out of this event becau.se:
- 1) The fire damper was in the closed position throughout the period; 2) The fire patrol which was set up performed an hourly inspection to guard against a potential' fire.

Robert G. Randall Supervisor, Technical Support Telephone No.: (315)349-2445 ABSTRACT A number of fire barriers at Nine Mile Point 'Jnit #1 were declared inoperable
.- in compliance with Tech. Spec. 3.6.10.1 (Fire ' Barrier Penetrations). In each instance a fire watch patrol was established in accordance with Tech. Spec.
'"' to perform hourly inspections until the appropriate repairs could be made.
Tech. Spec. 3.6.10.1.d requires that a special report be submitted to the NRC for fire barrier penetrations which are non-functional for more than 14 days.
These events do not constitute an LER per 10 CFR 50.73.
TEXT,
'S Between October 23 and November 5. fYre barrier penetrations T-24. TG-9,
. TG-78, C-120, C-123, DP-6, and W-221 were identified as being inoperable in compliarce with Tech. Spec. 3.6.10.1. These penetrations were discovered during preventive maintenance inspections which are perfonned according to procedure N1-FST-C2, " Fire Barrier Penetration Fire Seals Inspection". They were declared inoperable in compliance with Tech. Spec. 3.6.10.1.d, which states, " Restore the non-functional fire barrier penetrations to functional status within 14 days or prepare and submit a report in accordance with 6.9.2.b".
Work requests followed by engineering repair determinations were generated for each penetration repair. However, the repairs were not completed within 14 days, thus requiring that a special report be submitted in accordance with Tech. Specs.
Fire barrier penetrations OG-3, OGT-32, and T-205 were identified as being I non-functional prior to October 23. These penetrations were also not repaired within 14 days, and in addition the 30 day reporting requirement allowed in Tech. Spec. 6.9.2.b has been exceeded. . {

Qn Page CORRECTIVE ACTIONS ,e Occurence Reports are now being generated for all work requests involving fire barrier penetrations. This will increase tracking on fire' barrier repair progress, and ensure penetrations are repaired, and reports made within the Tech. Spec requirements. In each case the fire barrier penetration has been repaired and tested in accordance with the work requests and engineering determinations.
ASSESSMENT OF SAFETY CONSE00ENCES Because fire watch patrols were established in accordance with Tech. Spec.
no safety consequences arose as a result of these events. The fire watch patrols performed hourly inspections guarding against potential fires while the penetrations were non-functional. .

SUMMARY
OF ACTIVITIES AUDITED This audit was performed to comply with Technical Specification Section 6.13.2 which requires an outside consultant to evaluate l
the fire protection systems and quality accurance programs every ,
three years. The audit evaluated the fire protection systems and i
('
program implementation to verify that fire safety commitments to the United States Nuclear Regulatory Commission continue to be '
satisfied.
Fifteen of the fifty-seven Appendix R fire zones were selected at random and toured during the audit. Thirteen fire doors were selected at random and examined for their fire rating and physical condition. Twenty-eight fire barrier penetrations were randomly selected and examined for their integrity and condition.
Randomly selected fire detection and suppression devices were examined for configuration, arrangement, and condition using BTP9.5.1 and appropriate NFPA codes as reference.
The control of transient combustibles and overall implementation of Administrative Procedure AP-3.5 Revision 0, " Station Fire Protection Progre.m", was also evaluated.
Forty-seven fire protection procedures were reviewed, and evidence of the implementation of fifteen procedures was reviewed. The 1983, 1984, and 1985 fire protection audits and associated recommendations were reviewed; thirty open items from three previous audits were reviewed.
A review of the Technical Specifications was performed. A comparison between these specifications and the procedures
( resulted in several questions which were satisfactorily answered during the audit.

o M1-FPM-SA2 Maintenance and Inspection of High Pressure CO Halon Revision 2 2 l 1
The auditors reviewed one set of documents and found l the procedures to appear properly implemented. J
~
o NTP5 Fire Brigade Drill Training and Member Records, '
i Revision 1 The auditors reviewed training procedures and found them to be thorough; requirements of BTP9.5.1 were met.
2.2 Fire Zones The following fifteen Appendix R fire zones were toured and examined to verify compliance to the requirements of Appendix R:
R1A, R2A, R>B, R1B, T2B, D2A, D2B, D1A, D2D, R6A, D2C, C1, R4A, C2 and R3A.
. I Fire Break zones that were surveyed during this audit were found '
to be free of combustibles. The exception is the presence of one or two IEEE 383 insulated cables which may have passed through the Fire Break zone. These cables are not considered to be a significant fire loading or hazard.
No violations were identified.
2.3 Fire Doors The following thirteen fire doors were observed and examined for compliance with Appendix R requirements and BTP9.5.1:
' 132, 184, 243, 117, 56, 84, 149, 111, 108, 277, 110, 262, and 265.
Fire doors that were observed were in good condition except for two, which had problems with their closure devices. A work
(, request for repairs had baen written and the NRC was reportedly notified. 90 other problems were noted.
FIREPRO File: 57N1782 Page 4 January 14, 1987
2.4 Fire Barrier P+netrati,ns l The following twenty-eight fire barrier penetrations were observed to verify their integrity and condition:
OG20, P-7, P-27, P-28, P-29, P-11, P-22, D131, I1482, I1295, I1289, I1279, I1280, I1075, I1076, 11074, Il067, D30, D28, D85, D22, R60, C23, C20, C19, R154, R215, and R216.
No violations were identified.
l 2.5 Efre Drill and Fire Bricade ]
A fire drill was witnessed on 12/12/86 using Scenario (17. The drill was well executed and all requirements were met. j
)
The plant fire brigade program, training ready drill report and l fire incident reports were reviewed. The training records of i five randomly selected fire brigade members were reviewed. The records indicated that the five members reviewed had been trained in accordance with the procedure. No problems were noted.
2.6 Ouality Assurance Program for Fire Protection The Fire Protection Qualit.y Assurance Program dated October 28, 1983 was reviewed for conformance to USNRC BTP9.5.1. The program tracks the requirements very closely and appears to be adequate.
The Program and implementing procedures are vagus, however, with
. regard to responsibility and procedure identification. This
( concern was brought to the attention of QA Department management during the audit, and appropriate steps were initiated to review and revise the Program and implementing procedures as necessary.
In addition it was noted that NMPC Purchase Requisition #86001136 was submitted to the NMPC Purchasing Department with attached acceptable Attest Form and later changed without the use of the Attest Form. It was determined, however, that thu ultimate contractor used was on the QA Department Qualified Contractors i List, thus assuring vendor adequacy. Procurement controls will also be reassessed during the review of the Fire Protection QA Program, as discussed above.
The Nuclear Quality Assurance Operations Section performed fifteen (15) fire protection surveillance during 1986, resulting in two (2) NCR's (Nonconformance Reports) and six (6) CAR's (Corrective Action Requests). This surveillance coverage was felt by the auditors to be adequate and effective.
2.7 Previous Audit Findinas There are no NMPC QA Department audit findings open from previous audits.
The outstanding recommendations from the internal NMPC 1985 audit (5RAB Audit I) were reviewed. None of the recommendations
(. resulting from this audit have been addressed to date. Many are administrative in nature and none appear to be safety related.
FIREPRO File: 57N1782 Page 5 January 14, 1987

2.7 Previous Audit Findinca (CONTINUED)-
The 1984 audit (Gage Babcock Report) identified 169 open items.
' Five items remain open, and these have been identified as CAR l{
\ #86.3096.
The 1983 outside audit consultant recommendations were reviewed.
One recommendation remains open. This recommendation discusses the application of fire retardant material to new cables that are added to existing cable trays. This issue will be carried l forward internally by the Niagara Mohawk Engineering Department.
~
3 .0 EFFECTIVENESS -
Niagara Mohawk Power Corporation Nine Mile Point Unit 1 appears to be meeting.USNRC requirements and agreements, and has properly.
implemented the fire protection program procedures. The plant has a good level of fire safety commensurate with the hazards.-
The NMPC Quality Assurance Department is doing a satisfactory job of monitoring the fire protection systems, and is meeting or in some cases exceeding Fire Protection QA Program requirements.
The Fire Protection Quality Assurance Program is being addressed internally and will.be improved as previously discussed. J Housekeeping and control of transient combustibles was very good throughout the plant. The fire loads have not changed nor do l they present any greater exposure than those that previously existed. The review of procedural results and a physical plant tour indicates that the fire protection program and the* quality
( assurance activities meet or exceed United States Nuclear Regulatory Commission requirements.

~25-4.9.2 Ventilation Duct Penetrations Fire dampers are installed in selected ventilation system pene-tr& ions of the fire barriers in varieus parts of the plant. The major known exceptions are penetrations of the perimeters of the turbine building basement, the vaste disposal building, and the control room. The licenses will verify that labelled fire dampers are installed in all ventilating system penetrations of all fire barriers which separate cefety-related areas from each other or from areas presenting a significant fire hazard. In ventilation l ducts that pass through rated fire barriers,' the licensee will
! provide fire dampers with established fire ratings suf ficient to deter fires with the combustible loading in the given area. The fire dampers will be actuated by fusible links or emeke detectors.
All fire dampers will have ratings of three hours, unless the licensea justifies a rating of 1-1/2 hours.
During the site visit, the staff observed that the fire dampers installed in the auxiliary control reom ventilation system ducts were inside the room. Tire dampers are required to be installed at the point where the ducts in which they are provided pass throut the fire barrier. The licenses will install fire danpers in the ventilating system ducts for the auxiliary control room. and any other areas where fira dampers are required or provided, in the duct at the point where the duct passes through the fire barrier.
We find that, subj ect to implementation of the above described modifications, protection of ventilation duct penetrations satis ' .
fies the objectives identified in Section 2.2 of this report and is, therefore, acceptable.
4.9.3 Electrical Cable Penetrations Electrical cable panstrations in fire barriers are generally sealed with a variety of materials and designs, the fire resistance rating,
,of which have not been determined by any test method acceptable to
' the staf f.: The liqenses vill determine the ratings of axisting designs in accordance~vTe~hTIEEE-$tandard 634-1978. ..Thislest mathe; eestYThestaffmquirements for tests of electrical cable penetra-l tions; except that it does not provide a pressure differential acros the barrier equivalent to the maximum expected in the plant. There may be cable penetrations through fire barriers in the plant, acros, which pressure differentials exist. The fire resistance ratings of these penetrations will be determined with such pressure differentials applied during the fire test, if practical.
The licenses plans te provide rated seals en all cable penetrations in the plant coneensurate with the barrier rating.
We find that, subject to implementation of the above described '
modifications, protection for electrical cable penetrations of fire barriers satisfies the objectives identified in Section 2.2 of this report and is, therefore, acceptable.
4.9.4 Piping Penetration Piping penetrations through fire barriers, except for those in the reactor building, are generally not sealed. The licenses has not indicated the fire resistance rating of those penetrations which are saaled.
The ite.:. ee .'ill tgproposed piping penetrations in accordance with ./. .e ar seccions of IEEE Standard 634-1978, " Cable Pene-tratio Tira S'op Quali*'.cu ion "est", although this test aethod is not - @ ,d for piping penetrations. . The licensee vill in-stall ,*..n, penetrations with fire resistance ratings equal..to the bsr w s thay. penetrate. The licensee plans to seal all piping penetrations between safety-related areas, and between safety-related and nonsafety-related areas.
We find that, subject to implementation of tha above described modifications, protection for piping penetrations pf fire barriers. j satisfies the objectives identified in Section 2.2 of this report and is, therefore, acceptable.
4.10 Separation Criteria Separation criteria are not based upon Regulatory Guide 1.75" However, in most instances cable separation meets or exceeds the guidelines of that document for the Turbine and Reac'sr Buildings.
Sepai at".on of redundant circuits is achieved in the Turbine Building by routing cables on the East or Vest side of the building. Turther l separation is provided bp locating trays above or below floor el,evation l 261 feet. Any one of the following groups of Turbine Building cable trays ensures safe shutdown of the plant.
- 1. Cable Trays above Elevation 261 feet, or
- 2. Cable Trays belov Elevation 261 feet, or l 3. Cable Trays above and belov Elevation 261 feet on the East side, or~
