organization personnel made inappropriate decisions on ITS equipment due l

'

to a lack of design bases knowledge emphasizing the need for a broad dissemination of the ITS systematic review. During the inspection period, operations personnel handled all transient events in a professional manner, but some minor deficiencies in handling routine administrative functions !

were note Fuel receipt inspection was generally handled well. Continued examples of untimelyresolution of deviation event reports were observe The present drawing control system places a significant burden on the production organization to maintain the as-built status. This burden increases the likelihood of using an out-of-date drawing. Two unresolved j items were ider,tified (Paragraph 3) and seven open items were identified -j

The inspector also reviewed a memorandum from the maintenance and modification superintendent to all' maintenance staff, NP-MA-89-0134, which discussed this situation and the necessity.for proper storage of material The inspector reviewed traini_ng records-that indicated that all. maintenance supervision had been trained-on proper material storage procedures. The inspector noted tha maintenance news letter item had been generated that. discussed proper -

storage of material. Based upon the inspector's observation of the uncontrolled storage area and the training records this matter is -

considered close (0 pen) Unresolved Item (341/88003-02(DRP)): Inservice test requirement for RHR service water discharge valve. On June 26, 1989, the licensee informed the inspector that there would be a meeting between the licensee and NRR to discuss the applicability of this valve to the Inservice Test. Program. The meeting was scheduled-for late Jul c. (0 pen) Violation (341/89007-02(DRP)): Inadequate corrective actions to the utilization of an. improper head correction factor on a HPCI flow transmitter. The response to the violation-was unclear to the inspector as to what procedures would be change In a meeting on June 5,1989, the inspector informed the licens'ee of this condition.and requested that the information be provide Once received this information would be documented'in an inspection report to provide adequate documentation for the NOV. response. . In subsequent meetings with the licensee on July'10,17.and 24, the inspector continued to request the information. The licensee indicated that the information was being prepar~e d. (Closed) Violation (341/87038-02(DR_P)}: Failure to verify closed and locked valves as required by Technical Specification.4.6.1. Following'a walkdown and review of the core spray system, the inspector initially identifie2 two drain valves not included in procedure NPP 24.425.01, " Primary Containment Integrity Verification," and in a subsequent review of the HPCI and RCI systems, identified eight other valves not included in the procedur The subject procedure implemented Technical Specification 4.6.1.1.b

!

'

which requires' monthly verification that primary containment penetration valves not-capable of being automatically-closed are closed and capped where required. The procedure also required ~the l verification of correctivalve' positions of the automatic isolation j valves. 'These findings indicated that further review into other l

systems was required and the subsequent review by the licensee

'

identified 76 test, vent and drain (TVD) valves outside containment, six TVD valves inside containment, and'five bonnet taps that were not included in the surveillance procedures. An inspection of the above omissions showed that the valves were properly positioned by standard operating procedures and'no violation of primary containment had occurre Procedures NPP 24.425.01 and NPP 24.425.03, " Primary Containment Integrity Verification for Equipment Inside Containment,'".

were revised to include the above TVDs and bonnet taps and the procedures were performed. In addition, a surveillance improvement plan was undertaken in 1988 to upgrade the licensee's overall performance in this area. The inspector reviewed the Technical Specification Improvement Package for Technical Specification 4.6.1.1, " Primary Containment Integrity," and the revised procedures NPP 47.000.77, " Test, Vent and Drain Valve Cap and Plug Verification," NPP 24.425.01 and NPP 24.425.03. The review included a 100 percent examination of TVDs by comparing those valves on functional operating sketches (F05) with those in the revised procedure, NPP 47.000.77, using the criteria for pipe cap / plugs established by the licensee in letter NE-NS-85-0118, dated December 2, 1985. A random examination of the valves, caps and plugs in Procedures NPP 24.425.01 and .03 was also performed. A hands on inspection of selected valves for correct positions and cap installations was also performed. The inspected valves were found to be correctly positioned with properly identified caps, where require The inspector reviewed the last scheduled surveillance procedure checklists for the above procedures and found them to be properly complete In the course of the above procedure reviews using the UFSAR and the FOSs, several minor errors were found, two in the UFSAR and four in various FOSs. These were reported to the licensee and corrections were initiate (Closed) Violation (341/87040-03(DRP)): Failure to maintain Primary Containment Integrity on the Primary Containment Radiation Monitoring System (PCRMS). In January 1984, the licensee determined that the PCRMS did not comply with the UFSAR. The requirements allowed single remote manual isolation valves on essential closed loop systems outside primary containment. However, the PCRMS was not qualified to containment design accident pressure and portions of the system were not seismically or materially qualifie Therefore, the PCRMS was not essential following a LOCA and the system would automatically isolate upon receipt of a LOCA signal (high drywell pressure). To confirm the requirements for a non-essential closed loop system automatic isolation valves were added, but the UFSAR was not updated nor were the Technical Specifications amended to included these valves. In addition, the modification to install the valves did not provide for the inclusion of these valves in the Fermi testing program, i.e. functional testing, logic testing, position indication check, or local leak rate testin On October 17, 1987, during implementation of another modification of the PCRMS, the use of these valves for system isolation was questioned since they were not included in the UFSAR or Technical Specifications and had been left open during the modification. In addition the valves were not properly qualifie This violation of primary containment integrity was immediately reported on the ENS and by LER 341/87-52 on November 14, 198 This violation resulted

in the imposition of a Civil Penalty, issued via letter dated June 16, 1988, for failure to determine that the 1984 modification was not an acceptable alternative to 10 CFR 50, Appendix A, General Design Criteria 56, that a Technical Specification Amendment was not processed and that procedures were not put in place to periodically test the valves in accordance with 10 CFR 50, Appendix J, and other testing requirement Following the detection of the violation, the licensee applied for and was granted a temporary exemption from the GDC 56 requirement for the PCRMS on I;ovember 13, 1987. In the interim, until March 29, 1988, when the NRC approved a Technical Specification Amendment accepting a permanent PCRMS design configuration as an acceptable alternative to GDC 56, the licensee tested the in place valves in accordance with. Technical Specifications. Daily inspections of the valves and associated piping were also made. The Emergency Operating Procedures were revised to included actions for isolation of the PCRMS and training was provided to all licensed operators on these change The 1984 modification on the PCRMS took place before the operating license was issued. Subsequently, the program to make and verify design modifications has been formalized, strengthened and includes various reviews of the design adequacy as well as review of previous commitments made to the NRC (UFSAR, TS, NUREG, IB, etc.). In addition, the licensee has improved the safety evaluation program and provided training in this program to appropriate employee (03en) Open Item (341/89008-03(DRP)): Determination of the cause of CCiVAC Division 2 fan motor failur On July 13, 1989, the engineering research department (ERD) report on the failure of the fan was received by the inspector. Upon initial review the inspector noted that the report was dated June 20, 1989, and questioned the timeliness of the report distributio After additional interviews with licensee personnel the inspector ascertained that the original draft was completed on June 20 and additional concurrences within ERD were required prior report submittal to the site. The eport probably reached the site on July 10 or 11. However, the inspector commented to licensee management that issuance of the report was untimely especially

'since the verbal evaluation of the motor failure was provided to the cognizant system engineer during the week of June Upon review of the report the inspector noted the documented cause of the motor failure was not consistent with the system engineer's understanding of failure based upon the ERD verbal report. The ERD report stated, "The cause of high vibration appears to be attributable to a failure of the bearin The lubricant appeared l to be contaminated with water which accelerates pitting type l failure . . . " Unfortunately, the bearings were degreased prior

'

to transportation to ERD so no analysis of the grease could be performed. The inspector immediately contacted the system engineer

Following the. failure.of the' Division 2 fan in February 1989, the inspector inquired as to what actions the licensee intended to take:

with.the Division 1 fan.' . Originally, licensee personnel had decided ~

to . inspect the bearings at the earliest system outage. However,.

subsequent determination was made that the motor vibration could be monitored and if vibration increases were observed the inspectior:

would be accomplished. This' reduced manpower constraints and the inspector considered the monitoring a viable alternative. .The first set of vibration data revealed acceptable result When the written report was" issued by ERD,. the' inspector inquired as to the status of the Division 1 fan. At this time the enginee informed the inspector that--another set of vibration ~ readings had been taken and indicated increased vibration, but not into the.'

action level.- The engineer also stated that the work request to inspect the motor bearings would be scheduled for the upcoming CCHVAC Division 1 outage on-July'1 On July'20, the inspector inquired H maintenance craft personnel as to the results of the motor inspection. Craft personnel responded that no motor / bearing inspection was performed or was scheduled to be performe The inspector immediately contacted the cognizant. engineer, scheduler, planner and appropriate supervision to codirm that the bearing inspection had not been accomplishe From'these interviews the inspector confirmed the craft statements. The reason for the cancellation of the inspection was lack of an available spare moto A week to two weeks prior to ERD report issuance the system engineer J and planner had discussed the bearing inspection and the system

'

.

engineer considered the. inspection conditional upon availability of a spare motor. The planner checked that the purchasing department had a buyer's worksheet for the motor. The inspection was added to the scope of the upcoming CCHVAC outage on' July 1 The Thursday (July 13th) prior to the scheduled CCHVAC outage, .

I maintenance and planning personnel reviewed the work to'be performed 1 and the bearing inspection was cancelled since the spare motor had .

not been received. The ERD report had been received a=few days  !

earlier, but the systems engineer had not contacted the planner to J specify eliminating the net.d for the spare motor to perform the- j inspection. The systems engineer was unaware of the cancellation  !

until-informed by.the inspector on July 2 The inspector inquired as to whether the operating authority had been I informed of the bearing vibration condition. The technical staff-  :

personnel responded that operations had not been notifie Also, the  ;

inspector inquired as to whether the motor inspection still could l be accomplished during the present system cutage. The licensee

responded that with system restoration already in progress, the l inspection could not take plac In a meeting on July 24, 1989, the inspector asked what actions

! the licensee' intended to take with the Division I CCHVAC fan. Ihe licensee responded that additional ' vibration readings would be taken and motor inspection would be accomplished in mid-August during another CCHVAC outag The inspector began an additional review into why it was taking so_long to procure a replacement motor. The inspector ascertained that the DECO procurement system uses an automatic. buy mechanism on components below a certain dollar amount. If the cost of,the item was greater than this amount'or the item was repairable an internal review must be accomplished before purchasing. The-internal review is accomplished by the use of an Internal Dispersement Review:

Form (IDRF). This motor' fell into the review category. Therefore,

~

a review and notification to the purchasing department was_ required

. prior to issuance of the buyer'.s worksheet. The buyer's worksheet is reviewed by the materials engineering group and quality assurance and returned.to the purchasing department. A purchase order is then generated by purchasin On February 10, 1989, the last CCHVAC motor in stock was used to __

repair the Division 2 fan. On February 14th the IDRF was generated by the computer in downtown Detroit. The IDRF was sent to the warehouse who forwarded the IDRF to the requisitioner of the motor just removed from stock on March 1st. Evidently, the IDRF ended up with the spare' parts expediting group in the maintenance departmen For reasons that are presently unclear to the inspector, the IDRF did not come to'the requisitioner until mid-May. On May 16th the IDRf was signed and submitted to the warehouse. On May 26th the warehouse entered the results of IDRF stating that a new motor must be purchased. On June 2, 1989, a buyer's worksheet was generated b the computer in downtown Detroit and was sent to purchasing onsit On June 12, 1989, the buyer's worksheet was sent to the materials engineering group (MEG) for technical- review. The MEG review w completed on July 18th and provided to purchasing to' issue a purchase order. This was one day after the commencement of the CCHVAC outag Presently, the new motor has an estimated delivery date of 16 to 20 week The inspector will continue to evaluate licensee actions with this fan and why purchasing activities took so'long for the spare moto (0)en) Open Item (341/88037-15(DRP)): Performance Enhancement Program (PEP) development. Subsequent to the curtailed licensee presentation on this program-in the monthly management meeting on June 29, 1989, the inspector met with the supervisor in charge of PEP developmen Based upon the presentation and interview the inspector noted that progress is being made in'this area but closure of this item would be prematur L

The licensee's conclusion was that no violation had occurred. The NRC reviewed the material provided and submitted a . letter date June 27, 1989. In this letter the licensee was' requested-to' provide certain information on the core spray and LPCI systems within 60 days. _This matter will be considered open pending submittal of the in b rmation and subsequent NRC' review.

Six PDCs, including the one'. identified by the inspector, were reviewed by Quality Assurance (QA). -QA concluded that th _

PDC identified by the inspector, 10153, would have been more

approp-iately documented on a DER, but the PDC rectified the situation in a controlled manner. The other five PDCs should not have been DERs. The inspector reviewed the surveillance and concluded _that a DER was. required for 10153 and that the other five PDCs did not require a DE The inspector met with cognizant QA personnel on^ July 14, 1989, and discussed the surveillance report. During the meeting the licensee identified that one DER has been issued to capture and trend CECO errors. At the end of 1989 the DER will be reviewed to ascertain-whether the CEC 0 error rate is sufficiently low. QA~ personnel stated that they would contact Technical Engineering to reiterate that as-found. discrepancies warranted a DE (0 pen) Open Item (341/87020-01(DRP)): Implementation of Exo-Sensor- u action pla PDC 7081 Revision A was issued on June 30, 1989.

Root cause of this violation was determined to be an incorrect application of Technical Specification 4.0.2 which allows for 25 percent extension to periodicities on routine surveillance. In this case the core spray differential pressure was to be checked at least once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> in accordance with a Technical Specification Section 3 4 Action Statement, not a Section 4 periodic surveillance. In 1 response, the licensee issued urgent Required Reading No. 88-4-6 which clarified the differences and included presentation of an additional note in Procedure 24.000.02, Attachment 10 specifying-that the 25 percent " grace' period" does not. apply to situation required ~' surveillanc (Subsequently, Procedure 24.000.01,

" Situational-Surveillance," was issued-and all requirements for the subject area were transferred from 24.000.02). Additionally, discussion of this topic has been included in operator training under Training Lesson Plan LP-0P-802-102, " Plant Administrative Procedures." The inspector verified all operators had reviewed URR 88-4-6, Procedure 24.000.02, Attachment 10 as revised, and that the training lesson plan explicitly included the subject topic (reference Training Change Request I-89-0567). This item is close (Closed) Violation (341/88030-02(DRP)): Failure to deenergize containment lighting circuits in accordance with Technical Specifications 3.8.4.1 and 3.0.4. The licensee subsequently determined the cause to be personnel error in performance of

'

the drywell closecut evolution as well as an unclear. procedure ,

as to the requirements governing the closeout. An accountability meeting (No.88-034) was' held between management and all involved personnel, and those involved in the failure to deenergize the circuits as well as those who authorized a'scension in-power were counselled and/or disciplined. Additionally, Procedure 23.425.01,

" Primary Containment Procedures," was revised to clearly specify -

the Technical Specification requirements to deenergize the subject circuits, and a Lessons Learned (Document No.88-015) was issued on the event (which was included as required reading for all operators). j The inspector reviewed licensee corrective actions and found them -

Item 4: Lubrication identified in CECO differs from that 'specified.in vendor manuals. Provide documented evidence that proves equivalency for lubricants used in safety-related appl _ications. The inspector reviewed Deco Engineerir.2 Rmeh

! Report No. 89B73-8, Revision 1, " Comparison of Lubacants in tae Fermi 2 Lubrication Manual and the Manufacturer's Maintenance Manual," issued May 10, 1989. The report documented that in every instance where the lube manual differed from the manufacturer's (vendor) manual the quality of the lubricants recommended were equal to or-superior to the products recommended by the manufacture Item 9: During the performance of corrective or preventative maintenance activities, when lubricants are found not in'

compliance with CECO, they shall be changed out at that time.

' These situations shall be documented on a DER. The licensee's position on this issue is to document each discrepancy.on a DER and evaluate each on a case by case basis. Region III will continue to monitor the disposir. ion of any future DERs involving lubrication issues.

The following are inspector comments regarding items which ar partially complete:

Item 3.a: Verify by sampling the technical accuracy and thoroughness of CECO compared to Revision 8 of the Lubrication Manua This item is being performed to ensure that incorrect data was not entered into the new computerized CEC 0 database during the changeover from the hard copy lube manual. -QA took a sample and identified 17 discrepancies. Fifteen discrepancies involved Dolium S being specified in the hard copy lube manual while the correct Dolium R was specified in the CEC 0' databas Dolium R was incorrectly changed to Dolium S.in the' hard copy lube manual by the site lubrication engineer when he learned that Dolium S was an improved product over Dolium R but'had not yet been marketed and distributed by Shell. Subsequently, the product was never distributed due to test results. This example highlights the ease with which the lube program could be changed without independent revie Item 3.d: Assess user friendliness of CEC 0 relative to lubrication requirements.

, Operational Safety Verification (71707)

The inspectors observed control. room operations, reviewed' applicable logs and conducted discussions with control room operators 'during the period from June 6 to July 16, 1989. :The inspectors verified the operability of selected' emergency-systems, reviewed tagout records and verified proper return to service.of affected. components. Tours of the-reactor building and-turbine building were conducted to observe plant equipment conditions, including potential fire hazards, fluid leaks, and excessive vibration and to verify that maintenance requests had been initiated for equipment in need'of maintenanc The inspectors, by observation and direct interview, verified that the physical security plan was being implemented in accordance with the station security pla The inspectors- observed plant housekeeping / cleanliness conditions and

. verified implementation of radiation protection controls. During the inspection, the inspectors walked down the accessible portions of the following systems to verify operability by comparing system lineup with plant drawings, as-built configuration or present valve lineup lists; observing equipment conditions that could degrade performance; and verified that instrumentation was properly valved and functionin * Diesel Fire Pump

  • Electric Fire Pump
  • Noninterruptible Air System-Divisions I and II
  • 130/260 VDC Batteries-Divisions I and II
  • High Pressure Coolant Injection The inspectors also witnessed portions of the radioactive waste system controls associated with radwaste shipments and barrelin These reviews and observations were conducted to verify that facility operations were in conformance with the requirements established under technical specifications,10 CFR, and administrative procedures. During .

these reviews the inspector's observations or findings were- During the inspection period the inspector asked what types of  ;

as-built controls had been placed on drawings utilized in the i

Technical Support Center (TSC) and the Emergency Operations Facility l (EOF). The licensee responded that drawings associated with-those l areas were handled under the normal drawing control process. The only drawings that received red-lining were the drawings in the ,

control room. The licensee expressed the same concern as to the I merits of maintaining drawings associated with the TSC and E0F in an as-built condition. Also, there were other problems that had been generated as a result of weaknesses in the drawing control progra I In a meeting on July 3,1989, the licensee indicated the existence

The inspector will continue.to follow the licensee's progress under the drawing jj control task force as an Open Item (341/89018-01(DRP)). ] During the walkdown of the non-interruptible air system the inspector noted that both divisions of the NIAS were color coded .)

orange for the compressor, the dryer, and other' major component ;

In a meeting on July 3,1989, the inspector requested the licensee '

review the' color code scheme on the two divisions to determine -i whether it was consistent with plant requirements. Subsequently, the licensee responded in a meeting on July .17,1989, that.there were no requirements for color coding major mechanical components, only electrical divisions. The inspector informed the licensee that with having both divisions-of NIAS orange, the' electrical color code for Division I, the chance of a wrong train equipment manipulation was increased, especially since both divisions are in the same room. The licensee committed to write a PDC on the condition and evaluate:its- 3 merit This matter is considered an Open Item (341/89018-02(DRP)). During the week of June 26, 1989, the inspector'noted an outstanding l work request on nitrogen cylinders to a mechanical brake on a RHR mechanical draft cooling fan. Inspector follow-up of this matter is considered an-unresolved Item (341/89018-03(DRP))'and will be documented in a future special safety inspection repor During the inspection period the inspector noted that one of the drain pot valves off of the HPCI steam supply system was malfunctioning. Further review with the operating authority identified that failure of either or both drain pot valves would not cause the licensee to enter into a Technical Specification limiting condition for operation. The licensee's rationale was based upon the fact that the system would continue to provide sufficient flow at the designated required steam pressures to meet the requisite Technical Specifications. Also, the valves in question were not designated primary containment isolation valves and, as such, their failure did not affect primary containment isolation or integrit The inspector further pursued whether any requirements were applicable to the drain pot valves. In the original SER these valves were questioned as to whether they should be taken into account as part of the 4 percent secondary containment bypass leakage limi However, in a subsequent SER supplement the main HPCI steam supply valves were taken credit for in that any leakage past those valves would be factored into secondary containment bypass leakage. As such, the inspector did not understand fully what the ramifications would be in a small break LOCA condition with the HPCI steam supply valves open. This matter is considered Open (341/89018-04(DRP))

.. * During the inspection period a RHR service water pump discharge check valve failed its inservice test requirement Subsequently, the licensee isolated that RHR service water pump and entered into 3 the 30 day Limiting Condition for Operation (LCO) as required by j Technical Specification 3.7.1.1. As a result of this condition the 1 inspector inquired as to whether that division of RHR service water was still capable of performing its safety function with one pump i out of service. In a meeting on June 12, 1989, the engineering )

authority informed the inspector that the mechanical stability of 1 the heat exchanger and RHR service water configuration would not {

be impaired by utilization of one pump. The inspector further j inquired as to whether the one pump configur6 tion would meet the necessary LOCA heat load rejection requirements. The engineering authority responded that two pumps were required to meet all the FSAR I assumption Inclusive in those assumptions were very restrictive tube fouling allowances associated with the efficiency of the heat exchangers. Through review of FSAR figures it was ascertained that with one RHRSW pump out of service in each train, somewhere between three and 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> into the post accident scenario, the necessary net positive suction head for all the low head ECCS pumps would be  !

lost rendering those pumps inoperabl l The RHR service water system is a support system for adequate j completion of the ECCS function. Loss of a LPCI division is a seven i day LCO. Seven days appears to be more consistent than the 30 days of Action 3.7.1.1. Also, Action 3.7.1.1.a.3 allows one pump in each subsystem of RHRSW to be inoperable for seven days. However, )

only through the operation of both RHRSW pumps can the safety function be accomplished. Based upon this information the inspector will submit a request for NRC review of the appropriateness of the 30 day LC0 associated with LC0 Action 3.7.1.1.a.1 and seven days for 3.7.1.1. During the last week of June the licensee informed the resident inspector that the drain pot for one division of the Non-interruptible Air System (NIAS) was not fully qualifie The ensuing licensee and inspector followup of this situation is considered an Unresolved Item (341/89018-05(DRP)) and will be documented in a future special safety inspection repor During control room panel walkdowns the inspector observed the flow indication for emergency equir nent service water (EESW)

reading 10% with the pump off. Tte inspector brought the condition to the control room operator's attention, who placed a control room information system (CRIS) dot on the indicator. During the inspection period a number of minor equipment malfunctions were brought to the attention of control room operators where no CRIS dots had been placed. The inspector discussed this matter with the operating authority so that the matter could be rectified. Later in the inspection period the inspector noted more vigilance on the part of control room personnel in CRIS dot application.

This EESW flow indication condition has been observed on numerous occasions in the past. The inspector ascertained that the problem is a design deficiency in the flow transmitter reference leg location which drains following pump operation. A potential design change, PDC. 9487, has been written to correct the problem. Implementation of the PDC is considered an Open Item (341/89018-06(DRP)).

h. On July 7, 1989, the inspector observed that the licensee had entered into a seven day limiting condition for. operation action statement for the diesel fire pump. Following a surveillance run of the diesel, the. fuel oil tank level had decreased to less than that allowed by the Technical Specifications. The inspector questioned control room personnel as to why tank level had not been checked following the last run of the diesel prior to the surveillance test and additional oil procure Personnel responded that maintenance activities had occurred earlier that week and the level was not checked at the end of post maintenance testing. The inspector informed plant management that entrance into this action statement could have been avoided by proactive performance of personnel at the conclusion of the maintenance activitie The licensee agreed and as of the end of the inspection period is contemplating procedural changes to correct the matte i. During walkdowns of the control room panels the inspector observed I Annunciator 2D96, "Drywell Equipment Sump Leakage High," illuminate The condition was brought to the attention of the control room operators who responded that this was a normal condition when the sump was in a recirculation mode and not indicative of excessive i leakag The inspector reviewed the Alarm Response Procedure (ARP) )

for this annunciator and noted that the recirculation condition was  !

not described as a reason for the alarm. This was brought to the j operetor's attention also. Subsequently, a memorandum was submitted i to the operations support group to revise the ARP. Completion of l the ARP revision is considered an Open Item (341/89018-07(DRP)).

j. During walkdowns of the control room panels the inspector noted that the recorder scale for Division II hydrogen / oxygen concentration was illegible. By cumparison with the Division I scale the inspector determined that hydrogen concentration was indicating 1.3 percen This is the upper most acceptance limit for the channel check of this instrument. The situation was brought to the attention of the operators who stated that they were aware of the situation and indicated a circuit board replacement was needed to remove the offse The inspector ascertained that maintenance was scheduled and the offset was eliminated by the end of the inspection perio The scale condition was brought to the operating authority's attention and a new scale was installed by the end of the inspection perio k. On June 23, 1989, while operators were performing a surveillance on l the High Pressure Coolant Injection (HPCI) System, Annunicator 1D61

'

SRV tailpipe temperature recorder located in the relay room reveale , :that K SRV was indicating approximately.220 degrees fahrenheit, the annunciator setpoint. When questioned by the inspector, operators initially . indicated that the.K SRV tailpipe temperatures normally ran'almost at'the' annunciator setpoint and-due to the. proximity of the tailpipe to the HPCI piping, sufficient heat was transferred

~

during the HPCI run so the tailpipe temperature eventually reached its setpoint.- However, when HPCI was subsequently shutdown, the annunciator did not clear. Additionally. during a power reduction on June 24, the annunciator cleared, and subsequently returned during the following power ramp-up. An investigation was then initiated to determine if K SRV was " weeping." The licensee eventually determined that the SRV was experiencing a small amount of leakage which had existed since approximately December 1988. Internally, and with General Electric assistance, the licensee determined that this was a low significance condition;. catastrophic valve failure or uncontrolled opening would not result and unit operation _could continue. The' inspector questioned operations personnel whether longterm trending was performed on parameters such as-these. The response was that no longterm' trends were'done but that the

. indication'was reviewed for short term (step change) trends and that conservatism of the annunciator setpoints, as well as redundant indications in most cases, minimized concerns for such longterm trending. The inspector. agreed with the licensee's determination of significance in this case, however, believed that cognizance of potential longterm degradation has benefit. The inspectors will continue to review trends of this type as part of the routine inspection progra No violations or deviations were identified in this are .

Monthly Surveillance Observation (61726)

The inspectors observed the offsite power source verification surveillance test required by Technical Specifications and verified that: testing was performed in accordance with adequate procedures, test instrumentation was calibrated, limiting conditions for operation were met, removal and restoration of the affected components were accomplished, test results conformed with Technical Specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personne The inspectors also witnessed portions of the following test activities:

  • 24.202.01 HPCI Pump Time Response and Operability Test
  • 27.106.04 Control Rod Drive Withdrawal Stall Flow Measurements
  • 46.601.01 Racon Model 13000 Microwave Intrusion Detector Calibration During the performance of 24.202.01, it was noted that E41-F029, HPCI steamline drain pot isolation valve, stroked approximately 40 percent in the closed direction rather than closing completely as required when HPCI was started. The redundant valve (E41-F028) in series with E41-F029 operated correctly. Therefore, the drainline isolation function was maintaine Further, when the system was shutdown, E41-F029 did not stroke open as required to restore the drain path from the drain po This is an example of the inspector concern discussed in paragraph of this repor The inspectors performed a records review of completed surveillance test The review was to determine that the test was accomplished within the required Technical Specification time interval, procedural steps were

During the inspection period, the licensee. experienced several events, some of which required prompt notification of the NRC pursuant to 10 CFR 50.72. .The inspectors pursued the events onsite with licensee-and/or other NRC officials. In each case, the inspectors ver.ified that i the notification was correct and' timely, if appropriate, that the licensee was taking prompt and appropriate actions,'that activities were conducted-within regulatory requirements and that corrective actions would prevent future recurrence. The specific events were as follows:

  • June 8, 1989 - HPCI Level 8 Trip Unit Found Outside' Allowable Value During Surveillance - Retracted as a Reportable Occurrence. The licensee evaluated this condition and determined that'though the Level 8 trip was degraded, it still would have performed its safety functio The safety function is tripping the HPCI turbine prior to water. filling the steam lines This particular circuit utilizes a two-out-of-two logic. Therefore, failure of one of the level inputs is required to render the trip function inoperable. In this the function was available but incorrectly set. The licensee provided .

a letter dated June 2, 1989, from General Electric to support their i position. The inspector reviewed the licensee's rational and concluded that the situation fell within engineering judgement, ,

barring additional input from AE0D on this matte )

Within the last quarter this same condition was noted on a RCIC l Level 8 trip unit. RCIC utilizes this same logic configuratio The licensee had used the same rationale for not reporting that l situation. The inspector expressed concern as to whether there'

l was a generic drift condition being exhibited on the Level 8 l transmitters. Of special concern to the inspector was the third l Level 8 trip system for the feedwater turbines and main turbine.

The Level 8 trip system is the one taken credit for in the accident analysis. The licensee evaluated the calibration data and reported that they could not identify a similar problem with this trip system 4 or any problems with the other Level 8 transmitter )

During the afternoon with two air compressors out of service, another at diminished capacity and a temporary compressor'in-service, the temporary compressor failed. The air header pressure dropped to 80 psi causing automatic initiation of the two non-interruptible air system (NIAS) compressors before the diminished capacity compressor could be placed into service. None of the air users exhibited degraded performance and operators dealt with the situation in a -

controlled and professional manner. . Subsequently, the temporary compressor was restored to service. The inspector reviewed whether ;

this situation, automatic initiation of the safety-related air I compressors, was reportable as an engineered safety features (ESF)

actuation. The inspector concluded that the UFSAR and the SER did not identify NIAS as an engineered safety feature and therefore reporting under 10 CFR 50.72 or 10 CFR 50.73 was not require However, automatic initiation of NIAS does meet the spirit of the reporting requirements. NIAS is a-standby power system much akin to the emergency diesel generators (EDGs). The EDGs receive automatic initiation signals on loss / degradation of the incoming nonsafet related power source (voltage) as well as on a LOCA signal. The NIAS compressors also receive automatic initiation. signals on loss / degradation of the nonsafety-related power source (air) and on a LOCA signal. Without the NIAS compressors in service during a design basis LOCA, numerous' systems necessary to mitigate the ;

accident would not function just as is the case for the EDGs. The i inspector requested the licensee to review this situation under the voluntary reporting aspects of the LER system. .The inspector suggested the licensee consider reclassification of the NIAS as an ES In addition, the inspector will pursue reclassification of i the NIAS as an ESF through appropriate internal regulatory avenue * July 13, 1989 - Notification to MDNR of Residual Chlorir,e Dir, charge to EF-1 Overflow Canal During GSW Chlorinatio i

l * July 14, 1989 - Reactor Power Reduction. At 2200 on July 13, 1989, the No. 2 turbine intercept valve went closed unexpectedly. This event coupled with the power reduction to reduce radiation levels in the area of the failed valve caused feedwater level perturbation At 0800 operators lowered the level in the reheater seal tank to i stabilize the level problem. Stabilization was achieved at 67% power '

but increased the feedwater temperature to the reactor vessel to i excess of the limit established in Procedure 22.000.02. Later that day the inspector met with operations, General Electric and engineering personnel to disc"ss the ramifications of the higher feedwater temperature. The licensee explained that the upper temperature limit was for optimum heat balance considerations up until the 100% power temperature limit. The temperature at 67% power was not greater than the 100% power limit. The inspector inquired as to the ramifications on feedwater nozzle qualification, soft seat check valves and any other piping component should this increased feedwater transient should have happened at 100% power. The licensee agreed to review this matte Review of the licensee's analysis is considered an Open Item (341/89018-08(DRP)).

Upon receipt of the LER the inspector reviewed its contents and began interviewing personnel as to the corrective actions taken. The LER indicated that an accountability meeting had been held, additional reviews would be performed on those surveillance being utilized for star lug installation, a lessons learned document developed and required reading on the lessons learned would be completed by July 1989. The inspector verified that the accountability meeting occurred and an additional I& staff individual was assigned to review the star lug procedure changes in addition to the normal required reviews. However, when interviewing the individual assigned development of the lessons learned document, he stated that the document had not been develope The inspector contacted licensing personnel informing them of the discrepancy in the LER. In a meeting with licensing personnel on July 10, 1989, the inspector was informed that a communication problem had occurred in preparing the LER and the LER would be revised. Also, plant staff could not support the end of July to complete the required reading and the revised-LER would include an end of August date to complete the required reading.

Bypass Function. On. June 7, 1989, while performing surveillance activities, I&C personnel identified that RBM B reference downscale trip setpoint was outside the tolerance of Procedure 44.010.152-and wrote DER 89-0663. On June 8, the inspector reviewed the DER and contacted the I&C supervisor as to the ramifications of the DER. The supervisor indicated that there had been a change to the reference downscale setpoint in the procedure and performance of this test was a part of changing the setpoint to be consistent with calculations / analysis. Since the downscale trip setpoint establishes the lowest power level at which the RBM system begins to enforce, the inspector inquired whether this change was conservative or non-conservative. The supervisor's impression was that the change was conservative but would check again. If non-conservative, the inspector requested the status of RBM No other conversations took place on this matter until June 19, 1989, when the assistant to the plant manager informed the SRI that both channels of the RBM did not begin enforcing at 30 percent power, the Technical Specification required value, but at 31 percent power. The day before, surveillance activities on RBM B had identified the same situation as that on RBM A and DER 89-0709 had been initiate Through the next week the licensee explained the history behind )

the calibration are traceable to the National Bureau of Standard The calibration due date for the wrench is the 47th fiscal week of 1989 based on the attached sticker. The inspector reviewed licensee Receiving Inspection Report No. 9-727177 dated May 24, 1989, which accepted the torque wrench along with other gauges supplied by GE. The GE torque wrench was used because it is " safer" in that there is no dial indicator and it slips at the required torque valu The licensee performed a vendor fuel fabrication audit, including meteorological aspects, at GE in May 1989. No concerns were identified in the calibration of equipment area during the audi All of the certified fuel inspectors are certified as Level I or Level II inspectors by a GE Level III inspector. Use of the torque wrench was included in the training program for the fuel inspector The NRC inspector had previously observed portions of the certification training activities and new fuel receipt inspection activitie In both cases the inspector observed close supervision by the GE Level III representative. Additionally, the inspector determined that independent verification is not required for the torquing of the channel fastener New fuel receipt inspection and channeling activities are controlled by Procedures NPP-82.000.01, Revision 21 and NPP-82.000.02, Revision 2 The inspector concluded that the procedures and documentation were appropriate to the circumstances. Training was sufficient to assure that the fuel inspectors have suitable proficiency in using the torque wrenc This allegation was not substantiated and is considered close . Review of the Diagnostic Evaluation Team (DET) Report A concern was identified in the DET Report regarding OSR0 meetings and is summarized as follows:

Approval of changes tended to be silent votes of approval with no dissensions expressed rather than a positive statement or action by individual OSR0 members signifying approval of each change discussed and considered at the meeting . . . procedure provided no assurance that OSR0 members voting approval of changes had, in fdct, reviewed the specific changes prior to voting. This same concern was also documented in QA Audit 88-0037 as Observation 2 . . .

The inspector reviewed QA Audit 89-0125 of the Safety Review and Evaluation Program which closed Audit 88-0037, Observation 2. The audit was cmducted in April 1989. The auditors determined that no similar situations were identified where OSR0 members conducting reviews were not familiar with the details required for evaluating the event. The inspector determined that Order FIO-FMP-01, Safety Review Group Organizations, Revision 3 (March 1989) requires distribution of documents to be reviewed at a scheduled OSR0 meeting five days in advance.

! A concern was identified in the DET Report regarding visual observation of valve testing on Page 72, and is summarized as q follows:

.

Valves were not being routinely observed during testing for indication of excessive valve vibration, jerky valve motion, binding, 1 unusual noise, overheating or other erratic problem The Executive Director for Operations (ED0) gave the Office of Analysis and Evaluation of Operational Data (AE0D) the task o evaluating this item to assess whether or not there was sufficient evidence to warrant a generic communication extending such visual observation to valve testing at other plant AE0D recommended that local observation during M0V stroke timing tests should not be required more frequently than already stated in Section XI of the ASME Cod The licensee has committed to continue to conform to this requirement and the NRC inspector confirmed that the licensee had met this commitment in the past. This item is considered close No violations or deviations were identifie . Preparation for Refueling (60705)

The inspector observed new fuel receipt and inspection activities during the inspection period. Approximately 10 percent of the 220 bundles received were viewed to ensure proper handling, control and inspection, and that personnel were properly trained to safely and adequately perform their assigned tasks. Associated activities observed included truck inprocessing into the protected area, radiation protection surveying, container offloading, bundle inspection and channeling, and assembly placement in the spent fuel pool. The first shipment arrived onsite June 12, consisting of 24 bundles. Subsequent shipments arrived approximately two per week with the last arriving June 2 During the inspection of bundle 04-33, a blemish on the clad was identified on rod H-7 between the fourth and fifth spacers. The licensee contacted General Electric for resolution / disposition. Subsequently, GE concurred that the bundle could be used as-i While placing bundle LYS 486 (27-54) on the fuel inspection stand, a portion of the top spacer near the outside corner was bent upon contact with the stand's top securing ring. GE recommended replacing the spacer with the work to be done onsite by Deco personnel under the supervision of a GE representative. This necessitated disassembly and reassembly of the bundle. The inspector. witnessed the disassembly, spacer replacement and reassembly operations and observed no weaknesses in their conduct. The work was performed in accordance with a Fermi approved Procedure 82.000.17, " Disassembly and Reassembly of Unirradiated Fuel." Tools were supplied by GE and were approved for their applicatio Further, the GE representative supervising the operation was very knowledgeable of the work to be performe __ _-

1 Regional Requests On July 6,1989, regional nianagement requested the inspector provide the Technical Specification limits and any licensee internal limits for reactor coolant leakage. The information was provided to regional management on July 13, 198 . Management Meetings On June 9, 1989, an enforcement conference between DECO and NRC Region III took place. The subject of the conference dealt with the original design inadequacies of the reactor building railcar door airlock as discussed in IR 341/89006. Opening remarks were made by the DRP Deputy Division Director followed by presentations by the SRI and DECO and the conference was concluded by closing remarks from the Deputy Regional Administrato At the end of the meeting some additional information was required for the NRC to complete their assessment of the situation. This information included:

  • The quantitative results of the secondary containment drawdown tests with deflated seal * Postulated radiological results of the deflated seal condition compared to 10 CFR 100 limit * Design document reconciliation program schedule and prioritization philosophy for selecting system * Flood test result On June 27, 1989, a continuation of the June 9th enforcement conference was held in Region III offices between Detroit Edison and NRC Region II The meeting began with a recount by the section chief of those areas where the NRC considered additional information from the licensee was necessar The Senior Vice President of DECO presented the conclusions that no Part 100 limit would be exceeded and the original evaluation on flooding was conservative. The head of the engineering organization provided a chronology of the events reiterating the safety significance conclusion that no Part 100 limit would be exceeded even without secondary containment integrity, using the most current Standard Review Plan guidelines, and that the original analysis was conservative. In addition he provided the difference between the more conservative UFSAR flood height limits and the Corps of Engineers height limit The licensee provided a discussion of the design basis document progra During the discussion the licensce stated that there would be an accelerated review of 10 systems. These 10 systems were rated

i as having the highest safety significance. The review for these 10 systems is scheduled to be completed by April 199 i c. On' June 29, 1989, a Monthly Management Meeting was conducted'in Detroit Edison's Nuclear Operations ~ Center. The topics are stated j below along with a short synopsis of what was provide j Plant Status The plant was at 100 percent power. Three of the five circulating water. pumps were inservice. .The'other two were out of-service due to local vortexing causing impeller and shaft damage. The unit was at power all of June with four LER reportable events occurrin Presently fuel receipt inspection was under way 'with minimal problems noted with the fue Refueling Preparation Milestones The licensee presented the milestones with special emphasis on those that had been missed. Originally, the licensee had scheduled all contracts for the refueling outage to be awarded by May 8, 198 As of the meeting, 10 of the 25 total contracts had been awarded with the remainder to be awarded by July 28. Also, the engineering ,

design effort was to be completed by June 1. Of the original 55 engineering design packages that were to be completed 32 were complete. Eight temporary modifications had been added that will be turned into engineering design packages. Of the 23 remaining to be completed, 15 were scheduled to be completed the following wee Performance Indicators The licensee provided a summary of the performance indicators from the second quarter of 1988 through May of 1989. . All' indicators were j generally favorable. The licensee did indicate that the number of '

reportable events or LERs would increase in the next monthly perio The majority of these events were characterized by the licensee as in the I&C are Following the discussion on these LERs the NRC entered into a discussion on LER 89009 as described in the licensee's monthly  ;

performance monitoring report. The NRC commented that the  !

information provided under root cause did not describe the root f cause. The licensee elaborated upon this matter and the NRC had a l- better appreciation of the root cause as'the licensee understood i ,

!

The licensee commented that, based upon the indicator results, further emphasis needed to be applied to improving the material condition of the plant. To improve the material conditions of the plant the licensee indicated that there were 40 maintenance workers that were presently in training who would be ready for the outage and that .

this additional manpower would be helpful in improving the condition l of the plan Also, an organization change had taken place in the maintenance department to reduce the number of management level l

The Senior Resident commented as'to whether the licensee had a method of tracking' rework in the maintenance area. The licensee-responded that they presently'do not but after the refueling outage they will be taking steps to initiate such a program. Performance

.

indicators in the material control area were provided. These indicators generally showed improvement in the ability of the warehousing personnel to provide material on request to the maintenance organizatio Lubrication Corrective Action Program The licensee discussed problems that had been noted in the lubrication area. The. licensee indicated that there appeared to be five main areas into which these problems could be categorize The first dealt with overgreasing the motors. The cause appeared to be greasing of bearings that were sealed bearings while the machinery was running. The fix was not to grease them.with the machinery runnin The~second area was mixed greas It appeared that the major cause of this problem was that the original manufacturer supplied grease was not consistent with the Deco specified grease. Therefore, subsequent corrective maintenance activities may have caused grease mixing. None of the mixed grease situations had resulted in

. equipir,ent degradatio The third area was wrong grease. Five instances of wrong grease were noted in rotating machinery. These occurred due to problems in the selection of the appropriate grease tube for the grease gun and the identification deficiencies of the appropriate grease through the Lube Manual / CECO data base syste The fourth area was no lubrication. Two motor operated valves were identified as.having no grease installed. They were subsequently lubricated and their inspection frequency increased to try to identify why there was no lubrication found installed in the' valve The fifth area dealt with administrative controls (specifically, the utilization of the lubrication manual versus the CEC 0 data base). Originally, the lubrication manual- was the document used for lubricatio However, there was a transition to the CECO data base which is a computer generated system. The computer i generated system had some interfaces that were not user-friendly I'

for identifying the appropriate grease. In the interim a red-lined lubrication manual was provided to the shift supervisor for his 1 understanding of what is the correct lubricatio ]

Following the identification of these five areas, the inspector requested the licensee to explain how the CCHVAC fan failure fit !

L into these five main categories. The licensee responded that the j fan failure was a potential sixth lubrication problem are j q

Detailed Control Room Design Review Human Evaluation Deficiencies In a letter'to the Commission the licensee made a. request to extend the time frame in which to complete a number of human evaluation deficiencies (HEDs). 'The licensee provided a status of the priority q 1 and 2 HED In total there are 166 of these' items, 96 of which a have been resolved. Eight require work at the refueling outage and 'l 62 do not need a refueling outage to complete. -Those that require 'l engineering design packages' constitute 26, 23 of whi.ch have been 1 completed by the engineering personnel and are ready for issuance to the field.'

' Corrective Action Audit Findings-The licensee provided a trend from June of 1988 to present as to the status of delinquent audit findings in excess of.90 days. From the-graph it'was apparent that the licensee had reduced the number of audit findings greater than 90 days old to one. This reduction from 13 in June of 1988 is commendable. Also, to fully understand toe

instruments will be completed in December 1990. Presently, the licensee is targeting generation of specific procedures for the Q1 and Q1M instruments in 1991. The senior resident inspector inquired j as to whether the B0P review and the Q1/Q1M procedure generation {

could be paralleled. The licensee stated that manpower constraints !

might limit such action j Other Plant Problems Following the presentation of the preventative maintenance program, the Section Chief requested information on the station air compressor j and condensate demineralized systems at the facility. The Plant i Manager responded that one compressor has a blown head gasket and !

one was operating at 75 percent capacity. Efforts were being made to acquire a backup air compressor-and to repair compressors that-were out of service. The NRC commented that given the level of !

preventative maintenance on this equipment, which is fairly high, .

that a root cause analysis as.to why the compressors failed and ;
