EXECUTIVE SUMMARY Duane Arnold Energy Center (DAEC)

NRC Inspection Report 50-331/99005(DRS)

.

This was an announced team inspection to review engineering and technical support and corrective actions. The inspection included a review of 50.59 safety evaluations and applicability reviews as well as a review of selected NRC issues from previous inspections. The following statements summarize the inspection results:

-

The inspectors concluded that the methods used to control design changes were effective. In general, design changes were designed, installed and tested in an acceptable manner. Design configuration controls were maintained throughout the modification process. System Engineering Change Packages (ECPs) were complete and of good technical quality. (Section E1.1.b.1)

-

Component level Engineering Maintenance Action (EMA) modifications were generally found acceptable, however, the inspectors concluded that several component level modifications contained inconsistent review documentation. One component level modification installed a 'B' recirculation pump motor snubber that contained the wrong oil. The installed snubber did not meet the current drywell radiation design basis. Based on the licensee's corrective actions, a Non-Cited Violation was assessed. (Section E1.1.b.2)

-

10 CFR 50.59 applicability reviews and safety evaluations were thorough and appropriate for the plant changes reviewed. However, the inspectors identified (Section E1.1.b.3) several EMA applicability reviews that inconsistently referenced the type of documents reviewed. The inspectors did not identify any unreviewed safety questions for the plant changes reviewed. (Section E1.2)

-

Temporary modifications were being controlled in an acceptable manner. In addition, the l temporary modifications were appropriately installed and tested. (Section E1.3)

-

The methods used in performing and revising design calculations for recent design changes were found to be correct and appropriate. The inspectors concluded that, while the final numerical results were acceptable, calculations at times lacked documentation to support how the conclusions were reached. This was considered a calculation control weakness by the inspectors. (Section E1.4.b.1)

-

The inspectors identified that the licensee did not include seven (7) updated UFSAR ( sections with the update letter submitted to the NRC on November 19,1998. However, the licensee was within the 10 CFR 50.71(e)(4) 24 month window to complete the update. The current plant UFSAR was updated July 15,1999. This was considered a j UFSAR update weakness by the inspectors. (Section E1.4.b.2) l

-

The inspectors concluded that acceptable engineering staff interface and support was j

'

provided during the modification process, and that final modification closeout packages were completed in a timely manner. (Section E2.1) l l

i

.

-

The licensee's operability determination process was effective. The operability determinations and supporting evaluations were acceptable and contained sufficient detail. (Section E2.2)

-

The inspectors concluded that the methods used to obtain and disposition industry operating experience were effective. The industry information reviewed had appropriate corrective actions initiated. (Section E2.3)

-

The licensee did not take appropriate corrective actions to control scaffolding installed j near safety related equipment. Based on the licensee's corrective actions, a non-cited violation was assessed. (Section E2.5)

-

The inspectors concluded that the licensee was safety conscious in electing to shutdown the plant for the degraded electrical penetration condition and to restore the plant's design configuration. In addition, the troubleshooting plan was well thought out and the post modification testing was good. (Section 2.6)

-

The inspectors concluded that the actions taken once a problem was identified were indicative of a good corrective action program. The majority of plant problems were identified, assessed, and had appropriate corrective actions assigned. (Section E7.1)

i

'

-

Root cause investigations were accurate and thorough. In addition, the licensee's trending program and effectiveness reviews contributea to identifying repetitive problems. (Section 7.2)

-

The inspectors concluded that the QA assessment process met 10 CFR 50, Appendix B, requirements. In addition, the quarterly assessments were identifying issues and the licensee was taking appropriate actions to correct these issues. (Section E7.3)

Ill. Enaine_erina E1 Conduct of Engineering i E Desian Chanoes and Modifications Inspection Scooe (37550)

The inspectors reviewed plant changes against the licensee's procedures and verified conformance with applicable installation and testing requirements. Accessible portions of the modifications were walked down and material condition of the surrounding areas were observed. The inspectors discussed the changes with the cognizant engineer when necessary to determine the rationale and extent of the change. The attached document list identifies the modifications that were reviewe Observations and Findinas

The inspectors noted that the licensee used two methods for controlling plant modifications, Engineering Change Packages (ECPs) and Engineering Maintenance Actions (EMAs). The EMA process expedited and streamlined component level plant modifications, while the ECP process was used for major system modifications, ECP Process - System and Plant Modifications The ECP modifications reviewed by the inspectors were of good technical quality, were thoroughly documented and received cross-discipline second level reviews. Associated calculations developed to support the modifications reviewed were of good technical 1 quality and were appropriate to support the design changes. In addition, the inspectors j

'

verified that the installation packages contained appropriate field instructions to ensure satisfactory installation, and found that the ECPs appropriately documented and dispositioned installation problems. Design configuration controls were maintained throughout the modification process and post modification testing (PMT) appeared effective in verifying that the modified system would perform it's design function. A sample of affected drawings were reviewed and were found to be appropriately revise The inspectors reviewed ECP No.1590, "ECCS Minimum Flow Instrument Modifications," which installed crud collection blow down chambers for these instruments. During the review, the inspectors noted that the modification package did j not identify a preventive maintenance activity or procedure that addressed periodic blow I down chamber cleaning. In response, the licensee indicated that periodic blow down l chamber cleaning had been overlooked. Action Request (AR) No.15891 was initiated l on June 16,1999, to correct this oversight. The licensee's prompt corrective action was Occeptable to the inspector l

b.2 ' EMA Process - Comoonent Modifications Overall, the component level EMA modification packages reviewed by the inspectors were acceptable. The inspectors observed that the majority of the EMA engineering evaluations clearly described the proposed design change; the design checklists were appropriately completed; and post modification testing was completed in an acceptable manner. However, the inspectors identified that some EMAs were not consistent in

.

quality. While some EMA's were well documented, others lacked such basics as the purpose of the component and it's safety significance. All of the EMAs met the EMA procedure requirements, however, the EMA procedure did not specifically describe the minimum expected EMA documentation requirements. The quality of each EMA modification package appeared to be driven by the particular staff member or supervisor responsible for the EMA rather than being driven by the component modification program or procedur The inspectors reviewed in detail EMA No. A40334 which replaced the 'B' recirculation I

'

pump motor snubber. Following Refueling Outage (RFO)15, the licensee identified that the installed 'B' snubber oil did not meet the Updated Final Safety Accident Report (UFSAR) stated drywell design radiation requirement. A,1 AR had been initiated to address this installation discrepancy. The 'B' snubber will be replaced during RFO1 The inspectors reviewed the operability determination performed for continued operation to RFO16 and determined that the snubber was operabl The inspectors determined that the preparer and reviewer failed to identify the appropriate snubber design basis requirement. The EMA described some of the appropriate UFSAR snubber related sections, however, the snubber radiation environment requirement was located in a UFSAR section that was not identifie CFR 50, Appendix B, Criterion Ill, " Design Control, requires, in part, that the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety related functions of the structures, systems and components and that design changes, including field changes, shall be subject to design control measures commensurate with those applied to the original desig The licensee's EMA modification process failed to identify the correct snubber oil radiation design requirement that was stated in the UFSAR. As a result, a safety related snubber was installed with the incorrect snubber oil. This is considered a violation (50-331/99005-01(DRS)). Based on the licensee's corrective actions, this Severity Level IV violation is being treated as a Non-Cited Violation (NCV), consistent with Appendix C of the NRC Enforcement Polic Utilization of Current Licensina Basis for Modifications The inspectors were concemed that EMA and 10 CFR 50.59 applicability reviews were not consistent in identifying Technical Specification (TS), UFSAR and other design basis documents that were applicable to the modification being performed. Seventy eight (78) percent of the EMA safety evaluation applicability reviews did not describe the TS sections that were applicable. A general statement that none of the plant TS sections were affected was typically used. As a result, a second level reviewer could not readily determine if all applicable licensing and design basis documents had been reviewe ,

%

The inspectors deteimined that the current UFSAR was available for review as part of

'

the plant's electronic database. The inspectors found that although the design information was available, it was not consistently used in preparing EMAs and their applicability reviews. In some cases, UFSAR sections described in the EMAs were not documented on the applicability reviews. .This was identified in EMA No. A34261. In other cases, two (2) similar modifications identified different UFSAR sections. This occurred between EMA No. 40334 and ECP No.161 The inspectors identified several modifications that used ASME Ill Code for the design changes where the UFSAR stated Code for component / piping was ANSI B31.1. This occurred when the safety relief valve accumulator flow control valves were replace The EMA applicability review for each of these modifications stated that this was not a change to the UFSAR. However, the inspectors were concemed that the licensee had deviated from a design commitment made in the UFSAR. In response, the licensee provided Code reconciliation documents for each of the EMAs. The inspectors -

determined that the Code reconciliation documents were acceptable. It did appear, however, that the EMAs should have identified the reconciliation documents. This documentation inconsistency was discussed with the licensee. The licensee acknowledged that the EMA proceduro did not require this type of documentation, and that the EMAs and applicability reviews should have identified the Code reconciliation document Several action requests were initiated to review the EMA process and to ensure consistent staff use of the UFSAR, use of the TSs and use of other design basis

.

documents during plant modifications. This was acceptable to the inupector b.4 Plant Walkdowns The inspectors and appropriate system engineer walked down ECP No.1590 in the RHR area and walked down the switchgear rooms, station batteries, and standby diesel generator room The inspectors observed that the safety related areas und equipment material conditions were good. However, the inspectors noted several birds nests in the 161 kilo-volt disconnect switch holders in the switchyard. Licensee personnel informed the inspectors that the bird nests would be removed at the earliest opportunity when these buses were made available for maintenance. This was acceptable to the inspector Conclusions .

The inspectors concluded that the methods used to control design changes were effective. In general, design changes were designed, installed and tested in an acceptable manner. Design configuration controls were maintained throughout the modification process. System ECP modification packages were complete and of good technical qualit The inspectors concluded that component level EMA modifications were generally found acceptable, however, the inspectors concluded that several component level modifications contained inconsistent review documentation. One component level

with regulatory requirements. Emphasis in this review was on design changes and modifications.10 CFR 50.59 applicability reviews and safety evaluations were i discussed with cognizant licensee personnel and selected evaluations were reviewed in detail to verify implementation and compliance with 10 CFR 50.59 requirements. The attached document list identifies the safety evaluations that were reviewe Observations and Findinas Safety Evaluation Process implementing procedures appropriately described the methods for controlling and 3 performing 10 CFR 50.59 applicability reviews. In addition, the inspectors verified that j 10 CFR 50.59 safety evaluations had been submitted to the NRC under J 10 CFR 50.59(b).

The inspectors verified that the licensee's safety evaluation training and qualification programs were conmstent with commitments made to the NRC. This included a review of the 10 CFR 50.59 lesson plans and training materials. The training materials appropriately presented NRC requirements and industry 10 CFR 50.59 practices. In addition, the inspectors reviewed three (3) recent Quality Assurance (QA) quarterly-engineering training program assessments and determined that QA observations had been factored back into the 10 CFR 50.59 training program.= Applicability Reviews and Safety Evaluations For the most part, the 10 CFR 50.59 applicability reviews and safety evaluations

- reviewed were appropriately prepared, of good quality, and were consistent with licensee pocedures and regulatory requirements. The inspectors independently reviewed applicability review and safety evaluation reference documents and determined that the evaluations appropriately addressed the review questions. However, as discussed in Section E1.1.b.3 of this report, several EMA applicability reviews were inconsistent in identifying the TS and UFSAR sections reviewe v

%' Conclusions The inspectors concluded that the 10 CFR 50.59 applicability reviews and safety evaluations were thorough and appropriate for the plant changes reviewed. However,

, the inspectors identified in Section E1.1.b.3 that several EMA applicability reviews

'-

inconsistently referenced the type of documents reviewed. The inspectors did not identify any unreviewed safety questions for the plant changes reviewe E1.3 Temoorary Modifications Inspection Scope (37550)

The inspectors reviewed the methods used to control temporary modificat5ns. This review included the controlling procedure, selected open temporary modification packages and their 10 CFR 50.59 safety evaluations or applicability reviews. Temporary modifications were discussed with cognizant licensee personnel. The attached document list identifies the temporary modifications that were reviewe Observations and Findinas The inspectors evaluated procedure No.1410.6, Revision 23, " Temporary Modification Control," and determined that the temporary modification (TMOD) pror.ess provided acceptable controls for installing temporary materials and equipment. A 10 CFR 50.59 applicability review and safety evaluation, if applicable, were completed prior to TMOD installation. The inspectors determined that the applicability reviews appropriately addressed their plant change. The use of a TMOD for longer than one operating cycle was strongly discouraged and required plant manager approval to be extended. The inspectors verified that the twelve (12) open TMODs had not been installed longer than one operating cycle. In addition, the inspectors verified five (5) TMOD installations and determined that they had been correctly installed. Also, the TMODs reviewed specified appropriate installation and removal testing requirement During review of the Temporary Modification Index, the inspectors identified on control roorn electrical drawing No. APED-E11-007<04> that terminal point CC-76 had been incorrectly marked when TMOD No.99-030, " Lift MO1908 leads routed through drywell penetration 1JX105A due to short circuits," was installed. The control room drawing and the work control center drawing reflected a lead lifted in Junction box IJ1765A rather than ,

'

terminal CC-76. Although the drawing incorrectly indicated the installed condition, it did not change the electrical function of the circuit. In addition, the inspectors verified that the correct lead had been lifted at terminal CC-7 In response, the licensee promptly initiated AR No.15558 to address this issue and corrected the affected drawings in the control room and the work control center. In addition, the inspectors reviewed additional drawings and verified that they reflected the current plant configuratio !

The inspectors selected design calculations that were important to plant safety and risk significant issues. The review included the methods used in performing and revising design calculations. Also, the calculations were reviewed for accuracy and to verify that appropriate design inputs, assumptions, and calculation methods were used. The attached document list identifies the calculations that were reviewe Observations and Findinas l l CAL-VC1-032. Revision 2. " Steam Break Pipe Analysis - Steam Pioe Tunnel" The inspectors noted that procedure No. ACP 1203.21, Revision 7, " Engineering Calculations," described the calculation program requirements. Calculations were to be sufficiently detailed as to the purpose, method, assumptions, design inputs, calculation methods, and conclusions such that a technically qualified individual could understand and verify a calculation conclusion without recourse to the originato The inspectors identified that calculation No. CAL-VC1-032 was missing relevant information regarding purpose, assumptions, list of applicable codes, special formulas and equation documentation. Further investigation into Revisions 0 and 1 also identified that this information was missing. The calculation was considered deficient by both the inspectors and the engineering staff even though the calculation conclusions appeared to be reasonable for this type of calculation. The licensee promptly initiated AR No.15224 to update the calculation. This was acceptable to the inspector The inspectors discovered that this calculation had been recently revised (Revision 2)

and the licensee had missed an opportunity to identify and to correct this deficienc Procedure No. ACP 1203.21 did not require calculations to be completely revised if the revision did not change the calculation results. This was considered a calculation control weakness by the inspectors. In response, the licensee initiated AR No.15223 to review the calculation control and revision process. This was acceptable to the inspector CAL-M97-015. Revision 1. "Re-assessment of Reactor Pressure Vessel Fatiaue Usaae" The inspectors reviewed the Reactor Pressure Vessel Fatigue Usage calculation. This calculation limits plant life by bounding how many times the plant can start up and be shut down. The calculation was revised when the fatigue limit value was changed. This

,

was accomplished by reducing the Code allowable allowance for the reactor vessel l fatigue limit. Reduction of this safety margin was allowed by the American Society of

Mechanical Engineers (ASME) Code. The licensee updated the UFSAR, however, the inspectors identified that the liccasee did not revise all pertinent UFSAR sections with the new reactor vessel fatigue limit valu The inspectors identified that the licensee had updated two (2) UFSAR sections, but did not update seven (7) additional sections that pertained to the fatigue limit value. The two (2) UFSAR section updates had been submitted to the NRC by letter No. NG-98-1767, dated November 19,1998," Cyclic Report of Facility Changes, Tests and Experiments, Fira Plan Changes and Commitment Changes." The inspectors were concemed that the UFSAR did not contain the latest material developed as required by 10 CFR 50.71(c) since the new fatigue limit value was less conservative. The licensee promptly initiated AR No.15752 and the affected plant UFSAR sections were updated July 15,1999. Six (6) months following the 1999 Fall refueling outage, these UFSAR sections will be submitted to the NRC. Even though the licensee had not updated all UFSAR sections,10 CFR 50.71(e)(4) requires that subsequent revisions be filled annually or six (6) months after each refueling outage provided the interval between does not exceed 24 months. The licensee was within the 24 month window and has taken prompt corrective actions to update the UFSAR. Therefore, this item is consider a weakness. In addition, the licensee did not identify to the inspectors any documents that would have been invalidated by using the incorrect fatigue limit value, Other Enaineerina Calculations

The inspectors reviewed several electrical and instrument and control calculations for adequacy of assumptions, completeness, and conclusions. The inspectors observed good documentation practices, such as, clearly stating the calculation purpose, listing verifiable design inputs, applying reasonable assumptions, specifying the verification method, such as, use design review or attemate calculation, and resolving verifier comment Conclusions The inspectors concluded that the methods used in performing and revising design calculations for recent design changes were correct and appropriate. However, while the final numerical results were acceptable, calculations at times lacked documentation to support how the conclusions were reached. This was considered a calculation control weakness by the inspector The inspectors identified that the licensee did not include seven (7) updated UFSAR sections with the update letter submitted to the NRC on November 19,1998. However, the licensee was within the 10 CFR 50.71(e)(4) 24 month window to complete the update. The current plant UFSAR was updated July 15,1999. This was considered a

The calibration was performed satisfactorily with the as-left readings within their acceptance criteria. In addition, the measuring and test equipment used were within their calibration interval. The inspectors noted that the instrumentation and control technicians were knowledgeable and qualified to perform the calibration. Also, the instrumentation and control supervisor was present during part of the surveillanc The inspectors observed breaker No. CB5560 maintenance work in the switchyard.

The attached document list identifies the operability determinations that were reviewe Obsety1tions and Findinas The inspectors determined that ACP No.114.5 acceptably described the methods for controlling operability determinations. The Operations Shift Uuperrisor (OSS) made the i initial operability determination on the AR form, if required. The 03S often requested evaluations from other organizations, such as, engineering.

This was noted in AR No.14186 which conservatively assumed that a three (3) pound box was modeled as a cantilever beam with all the mass concentrated at the end of the bea During this review, the inspectors noted that the Equipment issue Resolution database did not track equipment degraded conditions associated with open operability determinations, in some cases, the associated AR may be closed to another tracking document, such as, the work order system. The potential existed for operability determinations to be closed prior to correcting the degraded condition, in response, the licensee initiated AR No.15836 to correct this observation. This was acceptable to the inspector j Conclusions The inspectors concluded that the licensee's operability determination process was !

For example, operating experience discussions were provided by maintenance workers to their supervisor prior to performing a job (reverse job brief).

Operating experience binders were maintained in the maintenance shops. The maintenance works would review applicable binders prior to performing work to ensure operating experience was factored into their maintenance activity.

The inspectors reviewed the scaffolding control corrective actions identified in AR No. 8013, " Management Guidelines for erecting scaffolds in seismic / safety related areas,"

dsted October 1997. The review included procedures and records as well as discussions with cognizant licensee personne Observations and Findinas The inspectors identified that the corrective actions stated in AR No. 8013 were not

. accurately incorporated into the affected scaffolding procedures. The AR stated the following: (1) it was mutually decided to not make scaffold seismic, but secure; (2) to ensure two trains of a redundant system do not have unanalyzed scaffold, controls will be established to allow scaffold erection on one train only; and (3) if both trains require ,

scaffolding, engineering will evaluate one train for seismic adequacy. The as stated i corrective actions appeared reasonable to the inspector During a meeting on June 14,1999, the licensee stated that procedure requirements were implemented to ensure that oniy one train of scaffolding was worked on at a time during scaffold assembly. This would prevent the loss of redundant (both) trains if -i'

scaffold materials were dropped. However, the inspectors determined that the AR stated corrective actions were different than those implemented by the licensee since the ;

changes did not address installed scaffolding and its disassembly. In addition, the !

!

Inspectors identified that as a result of inadequate corrective actions, procedure N ACP1408.2, Revision 6, " Scaffold Control," and procedure No. GMP-CNST-09, Revision 6, " Scaffolding," did not have adequate scaffolding controls in place to ensure i that redundant (both) trains would not be common mode damaged during a seismic event. Scaffolding could be installed adjacent to redundant (both) trains or adjacent to one train with the opposite train out-of-service.- The procedures did not require that scaffolding be monitored from the time it was assembled until it was disassembled. In addition, the procedure did not require a structural engineering seismic evaluation if the

%

scaffolding was installed adjacent to redundant (both) trains. Also, the licensee did not ( have any bounding criteria to demonstrate that the scaffolding would remain standing during a design basis seismic event.

l

!

In response, the licensee initiated AR No.15838 to establish procedure controls for scaffold assembly, installed scaffolding and scaffold disassembly near safety related equipment.

,

10 CFR Part 50, Appendix B, Criterion XVI, " Corrective Action," requires, in part, that l: measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. The licensee did not take appropriate corrective actions to ensure that redundant (both) trains of plant equipment would not be damaged by scaffolding during a seismic event. Based on the corrective actions taken, this Severity l Level IV violation is being treated as an Non-Cited Violation (NCV), consistent with Appendix C of the NRC Enforcement Policy (50-331/99005-02(DRS)).

I ' Conclusions

- The inspectors concluded that the licensee did not take appropriate corrective actions to control scaffolding installed near safety related equipment. A non-Cited violation was assessed.

E2.6 Electrical Penetrations Inspection Scooe (92903)

.The inspectors evaluated the licensee's efforts to troubleshoot, repair and t,est shorted conductors in low voltage Electrical Penetration No.1JX105 Observations and Findinos Backaround

' in early May 1999, the licensee identified short circuits in electrical penetration conductors-to residual heat removal (RHR) shutdown valve control relays E11-K15A and K16A, and reactor protection system (RPS) main steam line position control relay C71 A-K3A. The RHR shutdown valve circuitry was requ! red to be operable only during shutdown coolin Relay K15A provided loss-of-suction protection for any running RHR pump. Closure of a shutdown cooling valve would energize the K15A relay to trip a running RHR pum Relay K16A enabled the Group IV isolation function if the shutdown cooling valves were open and the reactor vessel pressure was below 135 psi. Relay C71 A-K3A in combination with other main steam line valves less than 90 percent open would scram the

For the RPS circuitri the F3A relay was normally energized. A lead was lifted at terminal DD-48 placing this RPS chenel in the tripped condition per Technical Specification De-energization of this relay did not initiate a half scra During this operating period, the licensee revised operating procedures to reflect the 1 - plant's temporary configuration, and issued shift memo No. NG-99-0789 to alert the operators to the plant configuration changes while operating with a degraded electrical penetratio By May 20,1999, additional shorts had occurred in the same penetration and penetration l l header hole Nos.17 and 23. The number of conductors passing through each header 1 l

hole varied according to the wire size with about 419 conductors passing through the whole penetration. Since the penetration was not a modular design, the whole penetration would have to be replaced. These failures did not affect the containment pressure boundary. Since the failure mechanism was unknown, the licensee proactively commenced a reactor shutdown to repair the affected circuitry. Spare penetration conductors were identified and tested for use to restore the plant to it's designed

. configuration. A new penetration was on order, b.2 Troubleshootina. Reoair and Testina The licensee had initiated penetration No.1JX105A troubleshooting, repair and testing packages prior to shutdown. In additon, discussions were conducted with other utilities and with General Electric about proba >le causes for the short circuits. Since the conductors were potted in epoxy and c>uld not be observed, the only recourse at this time war. $t14entify r/Jeptable spare c)nductors. Because the root cause determination would bOh destructie examination, the actual determination would have to wait until the penetration was replace The inspectors reviewed the troubleshooting plan. The testing evaluated adjacent header hole conductors. About 90 field end conductors were de-terminated with about 79 of these conductors requiring re-termination. Overall, about 262 conductors were teste The testing verified conductor resistance to ground (open circuit indication expected) and verified conductor insulation resistance (greater than 10,000 megehms expected). Ten (10) conductors did not meet the acceptance criteria. In use circuits that passed the conductor tests but were within the area of influence near header hole Nos.17 and 23 where re-terminated to other header hole The inspectors reviewed the post modification testing for three (3) circuits. This included the RHR shutdown cooling circuitry (K15A and K16A), the RPS main steam line circuitry

l was due, in part, to having a QA trend coordinator that was knowledgeable about the plant. This contributed to making good trend assessment Root cause' training was provided to a large number of plant staff. The licensee performed root cause determinations for the most significant problems. Good root cause i evaluations and associated corrective actions helped prevent problem recurrence. The licensee stated that there had been a reduction in root cause investigations because significant plant problems were also decreasing. The inspectors did not identify any additional concems during the trend repod review The inspectors reviewed several QA effectiveness reviews. The licensee had identified several instances where corrective actions were ineffective. Additional corrective actions I were assigned to these problems. The inspectors determined that the QA effective

Safety Committee's 1998 and 1996 audits had identified a number of findings, however, appropriate corrective actions had been initiate Conclusions The inspectors concluded that the QA assessment process met 10 CFR 50, Appendix B, requirements. fra addition, the quarterly assessments were identifying issues and the licensee was taking appropriate actions to correct these issue E8 Miscellaneous Engineering issues E (Closec') Violation (50-331/97015-01(DRS)): Inaooropriate use of Reliability and Plant Level Performance Criteria. The following four systems / components were identified with inappropriate performance criteria: standby gas treatment system; fuel handling system; reactor building sump system; and hydrogen-oxygen analyzers. The inspectors reviewed the licensee's corrective actions addressed in letter No. NG-97-205 Corrective actions included the following: establishing appropriate unavailability and reliability criteria at the train level for the standby gas treatment system; establishing appropriate reliability and condition monitoring criteria for the fuel handling system; establishing appropriate reliability criteria for all of the reactor building sump system functions; and establishing appropriate system reliability and train condition monitoring criteria for the hydrogen-oxygen analyzers. The inspectors concluded that the licensee's corrective actions were acceptable. This item is considered close E8.2 (Closed) Insoection Follow-up Item (50-331/97015-02(DRS)): Performance Criteria for instrumentation used in Emeraency Operatina Procedures. This issue addressed the I creation of specific performance criteria for control room indication instrumentation. The !

licensee identified control room instrumentation specifically used by the operators to make emergency operating procedure decisions. Condition monitoring performance criteria were established to monitor all instrument failures. Reliability criteria were established at a functional level that could monitor failures if the instrumentation ,

associated with that function were lost. The scope of the instrumentation and the criteria '

established appeared appropriate. This item is considered close E8.3 (Closed) Insoection Fo!low-uo item (50-331/94011-01DRS)): Relief Valve Testina May Not Be in Accordance with OM-1 (Use of Certified Correlations). The licensee was resolving this concem by having the relief valve manufacturer perform tests and to develop certified relief valve correlations. This testing, however, was not scheduled to be completed for several years. In the interim, the licensee continued to use the correlations from the vendor manual in relief valve test procedure STP-NS590006, "ASME/ ANSI OM-1 Valve Testing." A note added to the procedure indicated that the correlation curves were under development by the vendor. The licensee was tracking this effort by AR No.15962 and would incorporate any temperature correlation changes into the relief valve test procedure, as appropriate. Based on the actions taken and planned, this item is considered close ~
