EXECUTIVE SUMMARY Perry Nuclear Power Plant NRC Inspection Report 50-440/99013(DRS)
An announced Nuclear Regulatory Commission (NRC) team inspection was conducted from July 12 through July 30,1999, to assess the effectiveness of the Perry Nuclear Power Plant's (PNPP's) engineering organization to perform routine and reactive site activities, including the identification and resolution of technical issues. The inspection team also assessed the effectiveness of PNPP's program for the identification, resolution and prevention of technical issues and problems that could degrade the quality of plant operations or safet Overall, engineering personnel dc.nonstrated a questioning attitude, a commitment to safety, and were knowledgeable, dedicated, and professional. However, some weaknesses were observed with attention-to-detail, timeliness of corrective actions, adequacy of documentation, and depth of technical reviews, in two particular instances, engineering personnel did not exhibit a complete understanding of the importance of compliance with licensing commitments and design bases, as described in Sections E1.5 and E2.2.b.1 of the repor The engineering organization was effectively performing routine and reactive site activities, including the identification and resolution of technical issues. Design change and modification packages, for the most part, were well-planned, comprehensive and technically correc However, specific examples where inattention-to-detail, lack of documentation to support engineering conclusions, and deficient technical depth were observed. Modification packages that contained risk and core damage assessment analyses demonstrated a sound safety focu Safety evaluations performed in accordance with 10 CFR Part 50.59 were thorough and showed improvement from previous assessments periods. Operability determinations were usually detailed and well documented, except for a few examples where inattention-to-detail and deficient technical depth were observe The corrective action program (CAP) was effective in identifying, resolving and preventing the recurrence of issues that could degrade the quality of plant operations or safety. The CAP was implemented with a low threshold for problem identification, the CR backlog was appropriately prioritized, and the use of CR trending to detect repetitive problems was well establishe However, the use of non-CAP tracking databases (e.g., ACTON) to manage organization work activities resulted in some conditions adverse to quality being entered into these databases without proper and timely corrective action resolution. Operating experience program material was appropriately incorporated into plant activities. Inter-departmental communications were successfulin promoting active staff participation in the CAP. Quality assurance audits and engineering self-assessment activities were thorough and identified performance based concerns. The following statements summarize the inspection results:
- Although instances where a lack of attention-to-detail were identified, in general, the modification packages reviewed by the inspectors were of good technical quality, well planned, and comprehensive. Modification safety evaluations and screenings were
,
reasonable and clearly described the proposed design change. The inspectors concluded that design configuration controls were properly maintained throughout the modification process and were effective. (Section E1.1)

The inspectors concluded that the 10 CFR Part 50.59 applicability checks and safety evaluations were thorough and appropriate for the plant changes reviewed. In addition, 10 CFR Part 50.59 procedures and training were consistent with commitments made to the NRC. (Section E1.2)
.
The inspectors concluded that temporary modifications (TMs) were being controlled in an acceptable manner. Existing TMs were appropriately installed and tested. However, a NCV was identified involving the failure of Document Control Department personnel to follow written procedures in posting a TM on control room, TSC, and EOF facility drawings and controlling a safety evaluation. (Section E1.3)
.
In most cases, the methods used in performing and revising design calculations for recent design changes were correct and appropriate. Documentation of the calculation purpose, assumptions, and design inputs had improved from previous inspection However, the inspectors identified one NCV where a calculation had not been revised in j a timely manner which resulted in a TS surveillance not being conducted utilizing conservative criteria. (Section E1.4)
l
-
The inspectors concluded that the failure to correctly derive ECCS pump TS surveil!ance !
requirements from the USAR was a violation of 10 CFR Part 50.36. The violation was cited and a response required as a result of the failure to submit the required TS amendment in a timely manner. (Section E1.5)
. The inspectors concluded that acceptable engineerir aff support was provided during the modification closeout process. (Section E2.1)
-
Overall, Engineering's support of the facilities and equipment, and its involvement with ;
and contributions to the plant's day-to-day operations, were satisfactory. (Section E2.2) i
.
The licensee's operability determination process was effective. Operability determinations and the supporting evaluations were acceptable. However, a NCV was ;
identified due to the licensee's use of an unapproved accident dose calculation method, j which resulted in not meeting the requirements of 10 CFR Part 50.72 and Part 50.73 for leakage outside containment. In addition, the licensee's use of regulatory limits in place
~ of design basis limits during an operability determination resulted in an unresolved item ;
pending further NRC review. (Section E2.2) !
- The inspectors concluded that the operating experience program was effectively ,
implemented. (Section E2.3)
- Two examples y ere identified where the document authors were not attentive to assuring that the documents contained the appropriate details. A CR did not discuss the relevance of iemoving the control. complex chillers' high temperature senor trip on the chillers' safety function and no bases were provided in the ECCS strainer debris i calculation for the engineering judgement used. (Section E3)

The inspectors concluded that the system and des'ign engineering staff interviewed were qualified and knowledgeable about their systems and system design issue (Section E4)
-
The engineering training and qualification program appeared satisfactory. (Section ES)
-
The inspectors concluded that, in general, the system engineers were providing good plant technical support and were knowledgeable about Maintenance Rule requirement The inspectors also concluded that plant housekeeping and material condition of safety-related equipment observed was good; there were a few areas where a lack of attention-to-detail was noted. A procedural weakness for monitoring safety significant hangers was identified by the inspectors. (Section E6.1)
-
The inspectors concluded the review committees effectively performed their duties of maintaining periodic review of activities, safety issues and evaluations. The inspectors concluded inter-departmental communications were effective in promoting active staff participation. The inspectors also concluded that the establishment of the Continuous improvement Group (CIG) demonstrated a rigorous attempt by the licensee to improve the plant CAP. (Section E6.2)
-
The inspectors concluded that the majority of plant problems were identified, assessed, and had appropriate corrective actions assigned. Establishment of the CIG, recent efforts to prioritize the "CR database" backlog, and the trending and binning of reports demonstrated that effective methods were being applied by the licensee to improve the CR action item program. (Section E7.1) l
-
The inspectors concluded that the ACTON database was not under effective management review and control. Therefore, there appeared to be a lack of an integrated, well managed program with management overview for all past and present plant action items contained in this database. The inspectors concluded that continued I effort would be required by the licensee to address and resolve this issu l (Section E7.1) !
-
The inspectors concluded that appropriate mechanisms were in place for self-assessments and quality assurance trending activities and that a number of plant and organizational problems were being identified. The licensee's trending program and effectiveness reviews contributed to identifying repetitive problems and inspectors !
concluded that QA investigations were accurate and thorough. (Section E7.2)

Report Detalis The purpose of this inspection was to assess the effectiveness of the Perry Nuclear Power
- Plant's (PNPP's) engineering organization to perform routine and reactive site activities, including the identification and resolution of technicalissues and problems. In addition, the inspection team assessed the effectiveness of PNPP's processes that provided the controls for the identification, resolution and prevention of technical issues and problems that could degrade the quality of plant operations or safet To accomplish this the inspectors evaluated whether engineering was appropriately identifying problems, implementing adequate and timely corrective actions, as well as providing the appropriate depth and attention-to-detail of the engineering work being performed. The inspectors' primary focus was on engineering products completed during the previous year, which were considered representative of the current performance of the engineering organization. The inspectors reviewed engineering processes, which included engineering's involvement in and contributions to condition reports (CRs), modifications (both permanent and temporary), calculations, safety evaluations, operability assessments and responses to generic industry and NRC concern . Engineering E1 Conduct of Engineering Overall, the modification packages reviewed by the inspectors were acceptable. Although instances of lack of attention-to-detail were identified, in general, the modifications reviewed by the inspectors were of good technical quality, well-planned, and comprehensive. Calculations developed to support the modifications adequately supported the design change Post-modification efforts were correctly implemented in that: in-service test (IST) and in-service inspection (ISI) programs were changed appropriately; the Operations staff received training on
' the modification where necessary; and the simulator staff was notified of plant changes Drawings requiring revision due to modifications installed during Refueling Outage (RFO) 7 (March 27-May 3,1999) were generally revised within the 45 day limit specified in modification procedures. Of the 2220 drawings requiring revision during RFO7 (720 safety-related system critical), only 6 still required further revision. A CR (99-1698) had been generated for the unrevised drawings to_ document the problems. This demonstrated a rigorous effort by the licensee to maintain safety-related drawings as current and accurate as possible. A sample of affected drawings was reviewed by the inspectors and found to be appropriately revise l Safety evaluations and screenings for plant modifications were reasonable and clearly
- described the proposed design change. For the most part,10 CFR Part 50.59 screenings and !'
safety evaluations for the modifications reviewed were appropriately prepared, of good quality, and were consistent with regulatory requirements and licensee procedures. The inspectors
' independently reviewed safety evaluation reference documents and determined that the evaluations appropriately addressed the review questions. Where unreviewed safety questions were identified, license amendments had been submitted and approved. The inspectors did not identify any unreviewed safety questions for the plant modifications reviewe l

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 chang ; Observations and Findinos The inspectors observed that the. licensee used the Design Change Package (DCP), the Simple Modification Request Form (SMRF), and the Equivalent Change Package (ECP)
for controlling plant modifications. The DCP controlled major system modifications, the SMRF was a streamlined process used for simple modifications, and the ECP was used to expedited component level plant modification Containment' Penetration Relief Valves' Radiation Endurance Evaluation l Modification SMRF 97-5088, "Over-pressure Protection for Containment Penetrations,"
Revision 0, dated November 14,1998, was developed to install relief valves at six containment penetrations to avoid over-pressurization that would result from heating and thermal expaneN of water trapped between the isolation valves as a result of a Loss of Coolant Accidein sOCA). Five of the six valves contained teflon-coated Viton stem seals. The teflon coating was provided for lubricatio Calculation EQ-154, " Service / Qualified Life of Nupro & Swagelock Valves When Used for Pressure Relief in Containment," Revision 1, dated May 4,1998, evaluated the ability of the valves' stern seals to withstand the radiation conditions associated with normal operation and LOCA, and still perform their design safety functions (i.e., open to relieve excess pressure and re-close to maintain the containment boundary). The calculation determined that the valves would be exposed to 1.94x10' rads gamma, that the radiation threshold of teflon was 2.7x10' rads, and breakdown of the teflon, with a resultant loss of tensile strength, would be expected. However, the calculation concluded that the teflon breakdown was acceptable, since the loss of tensile strength for this coating would not jeopardize the valves' operability. No evaluation was made of the potential loss of the teflon coating's lubricating qualities, and whether this could prevent the valves from opening at the correct pressure, or closing once they had opened. Failure by any of the five valves to operate in either direction could result in ,
significant containment degradatio ]
The licensee generated CR 99-1870, dated July 27,1999, and immediately contacted l the teflon manufacturer.' The manufacturer provided information which appeared to j support an operability determination for the teflon lubricating qualities at 2.7x10' rads; l
. however, it did not resolve the operability concems regarding the expected plant l radiation levels of 1.94x10' rads gamma. Based on the information provided, the J licensee determined that the valves were operable without reconciling the conflicting radiation level i i

i The inspectors were concemed that the licensee made non-conservative operability and environmental qualification determinations in the face of conflicting manufacturer information. Subsequent to this inspection, the licensee again contacted the manufacturer's representative for additional information on the teflon's lubricity. The representative stated that the original communicationt had been in error, that the teflon had been tested at radiation levels well above those that would be experienced by the valves, and that no reductions in lubricity had beu observed. However, no actual test data on this property at these higher exposure levels could be provided. Based on this information, the licensee documented this conversation, determined that the teflon was qualified, and concluded that the valves were operable. The inspectors had no further questions regarding this issu This issue was an example of inadequate depth of engineering. First, the licensee did not adequately consider all of the possible failure modes of teflon. Then, after having this concern raised by the inspectors, the licensee did not thoroughly evaluate all of the manufacturer's information in the attempt to demonstrate that the valves were qualified for their intended servic b.2 Hiah Pressure Core Sorav (HPCS) Caosbility As Reactor Core isolation Coolina (RCIC)
Backuo {
Design Change Control (DCC) 004 to E51-25, " Minimum Required Delta P Across the RCIC Pump For a Flowrate of 700 GPM," Revision 2, dated May 2,1999, was generated to support a potential operability determination for a surveillance test of the RCIC pump. The calculation determined that a RCIC flow rate of 670 gpm would i stabilize reactor level at 2 feet above L1 (the level at which the ADS system was actuated) for a reactor isolation event. It also determined that under the same conditions, HPCS would provide 517 gpm and stabilize RPV level at L1. The calculation concluded that RCIC performance was more limitin ,
The inspectors recognized that this conclusion was incorrect. If HPCS would not stabilize reactor level until it reached L1 and there was no margin, then ADS could actuate and the core could be uncovered. Consequently, HPCS would have failed to fulfill its design function as RCIC backup. The calculation did not recognize the HPCS system's performance was more limiting than RCIC's; it also did not identify that HPCS performance was unacceptable as describe Discussion with the licensee revealed that another analysis, NEDC-31984P (July 1991), j addressed the capabilities of both systems to meet the reactor level stabilization requirements for loss-of-feedwater events. Unlike DCC-004, it used lower reactor pressures corresponding to SRV electrically actuated relief setpoints. With this lower reactor pressure, both pumps would deliver higher flow rates to the vessel, which would
provide substantial margins to the L1 ADS actuation setpoint. Therefore, there was no '
actual HPCS operability concer Subsequent to this inspection, the inspectors discovered this same error in another calculation, E22-29," Evaluate HPCS Pump Performance Acceptance Cri?
Associated With the Higher Potential Reactor Pressure," Revision 4, DCC-073, dated April 19,1999. This calculation used the 517 gpm HPCS flow rate, shown above to be

inadequate, as a basic assumption. In response to this finding, the licensee generated CR 99-189 Both of these calculations were examples of inadequate depth of engineering review and a lack of attention-to-detai Diesel Generator Exhaust Back-oressure Due to Testable Ruoture Disks SMRF 97-5078, * Latching Mechanism for the Testable Rupture Disk," Revision 0, dated March 8,1999, changed the design of the diesel generator testable rupture disks (TRDs). Calculation R48-8, "EDG Exhaust Vent Valve Size," Revision 1, dated February 3,1999, was generated to show that the back-pressure produced by the TRDs would not degrade the diesel generators' performanc The inspectors found that although the calculation did use a flow resistance coefficient I to represent the TRDs, it did not appear to adequately account for all of the resistance factors (e.g., shape, momentum loss due to direction change, etc). A second calculation reviewed by the inspectors, R48 20, " Redesign of the Latching Mechanism for Testable Rupture Disk," Revision 0, dated May 15,1998, DCC-01, dated September 16,1998, also addressed back-pressure due to the TRDs. However, it only considered the TRD flow area, and it made no adjustments for flow coefficient or other resistance factors. Therefore, both of these documents calculated non-conservative back-pressures associated with the TRDs. Further review revealed that the level of non-conservatism in both cases was small when compared to the conservatism built-in to the calculations and the margin in the design. Therefore, there were no operability concerns associated with this observation. Both these calculations were examples on inattention-to-detail in the performance of engineering. In response to this finding, the
. licensee initiated CR 99-187 Inadeauate Evaluation of Holes in Valve Seat Rinas
In 1985, a modification was performed on valve 1E12F009 to drill a 1/8" diameter relief hole in one of the valve's seat rings to prevent pressure locking. While drilling the hole,
, 4 it was discovered that the downstream seat ring was being drilled instead of the upstream seat ring. The hole was not completed and NR COC-3672 was generated. It
- _ was resolved use-as-is based on
- (1) the seat not being a pressure retaining part; and
!
(2) the 150 psid design. In January 1999, during a review of past work documents, the licensee discovered that both of these reasons were incorrect and generated CR l 99-0015 to document the discovery. The CR acknowledged that the incorrectly drilled seat ring was in fact a pressure retaining part and evaluated it at a differential )
pressure (dp) of 1,500 psid, substantially above the maximum dp the seat ring would
,
experience. This CR was also resolved use-as-is based on the fact that even with this
'
higher dp, there would only be 20 pounds of force exerted on the area of a 1/8" diameter hol i l
The inspectors' review of this CR found that it had not addressed a more significant aspect of both the aborted and the completed holes on the seat rings' integrity - the seating and pressure forces applied to the seat ring by the valve disk. These forces would create stresses in the seat rings, and these holes would tend to increase the j 8 i

'
stresses due to reduction in load bearing area and the potential for stress concentratio Therefore, the licensee's disposition of the second CR also did not adequately address the effects of the hole This was an example of lack of attention-to-detailin engineering. As a result of the inspectors' concern, the licensee generated CR 99-1807 dated July 16,1999. It properly addressed the effects on the seat ring stresses which were found to be satisfactory, b.5 Miscellaneous Modifications ,
Modification DCP 98-0052, "Feedwater Leakage Control System (FWLCS) Single Feedwater MOV Improvements," was developed to suspend seat leakage and seat leakage hydrostatic testing of four feedwater check valves as well as implement a number of measures to improve the overall reliability of the penetration and improve the safety of the plant. The inspectors observed that the modification was of good technical quality, well planned, and comprehensive. Safety evaluations and screenings for the modification were reasonable and clearly described the proposed design change. The licensee's 10 CFR Part 50.59 safety screening and evaluation process identified a plant l change described in the Updated Safety Analysis Report (USAR) and an Unreviewed l Safety Question (USO). Amendment No.105 to the facility was filed on March 26, ,
1999, to address the issue. During the review, the inspectors noted that the l modification package contained rigorous risk and core damage assessment analyses for the actions being taken. When it was noted that operator action was involved in the Probalilistic Risk Analysis (PRA) models, a thorough human interactions evaluation was performed based on EPRI industrial standard DCP 98-05023, " Replace Existing Gearing w/ higher Gearing to increase the MOV Actuator Degraded Voltage Capability as Required by GL (Generic Letter] 89-10,"
Revision 0, was developed to obtain an acceptable motor operated valve (MOV) margin as specified by GL 89-10. During the review the inspectors noted an example where inter-departmentaf communications were effective in assuring that the valve stem received the proper lubricant. Recent MOV Users Group testing showed Mobil 28 grease provided better in-service results than the previously recommended greas Although the Lubrication Manual update was not complete, active staff participation correctly identified that the previously specified grease was no longer authorized and applied the correct lubrican DCP 96-04070,"Agastat F7000 Series Time Delay Relay No Longer Available Replace With 2 Relays to Provide Time Delay & Instantaneous Contacts," Revision 0, was developed because the installed relay originally qualified by General Electric was no longer available. The modification installed two new relays to provide time delay and instantaneous contacts. The SMRF package's engineering evaluations clearly described the proposed design change, addressed the equipment qualification evaluation, setpoint changes, the 10 CFR Part 50.59 applicability check, and provided acceptable post-modification testing. No deficiencies were note Equivalent Change Package (ECP) 99-08043 added a metal oxide varistor to the K49G relay that provided an actuation signal to the reactor protection system (RPS) from the
.
.
main turbine stop valve closure. The varistor provided a dampening effect on transient pulses. The ECP's engineering evaluations clearly described the proposed design
'
change; the design checklints were appropriately completed; the 10 CFR Part 50.59 applicability check was performed; and post-modification testing of the RPS was completed satisfactorilyi Overall, the SMRF and the component level ECP modification packages reviewed by the inspectors were acceptabl c. Conclusions Overall, the quality of engineering activities reviewed was good. The engineering products and the inspectors' interactions with the engineering staff indicated a commitment to safety at all organizational levels. However, several examples indicated that the depth of engineering reviews and the attention-to-detail were not always at acceptable level Although instances where a lack of attention-to-detail were identified, in general, the modifications reviewed by the inspectors were of good technical quality, well planned, and comprehensive. Modification safety evaluations and screenings were reasonable and clearly described the proposed design change. The inspectors concluded that design configuration controls were properly maintained throughout the modification process and were effectiv E1.2 10 CFR Part 50.59 Evaluations and Screeninas a. Inspection Scooe (37001)
The inspectors reviewed the licensee's program for 10 CFR Part 50.59 safety evaluations and applicability checks. The review emphasized design changes and modifications to verify adequacy of controls and compliance with regulatory requirements. The inspectors discussed 10 CFR Part 50.59 applicability checks and safety evaluations with cognizant licensee personne ' b. Observations and Findinas The inspectors verified that formal procedural guidane,e, including assignment of responsibility, was established for implementing 10 CFR Part 50.59 requirement Implementing procedures appropriately described the methods for controlling and performing 10 CFR Part 50.59 applicability checks. The 10 CFR Part 50.59 applicability checks and safety evaluations reviewed were appropriately prepared, of good quality, and were consistent with regulatory requirements and licensee procedures. In addition, the inspectors verified that 10 CFR Part 50.59 safety evaluations had been submitted to the NRC as require The inspectors verified that the licensee's training and qualification program was consistent with commitments made to the NRC. The inspectors reviewed the training materials to verify consistency with the controls, procedures, and guidance for 10 CFR Part 50.59 preparation. The inspectors verified that trained and qualified personnel performed the necessary applicability checks and evaluations. In addition,
%
.
the inspectors reviewed two recent 10 CFR Part 50.59 applicability self-assessment reports to verify that a feedback process was in plac Conclusions The inspectors concluded that the 10 CFR Part 50.59 applicability checks and safety evaluations were thorough and appropriate for the plant changes reviewed. In addition, 10 CFR Part 50.59 procedures and training were consistent with commitments made to the NR E1.3 Temocrary Modifications Inspection Scope (37550)
The inspectors reviewed the methods used to control temporary modifications. This review included the controlling procedure, selected open temporary modification packages, and associated 10 CFR Part 50.59 safety evaluations or applicability check Temporary modifications were discussed with cognizant licensee personne Observations and Findinos The inspectors determined that the temporary modification (TM) process provided acceptable controls for installing temporary materials and equipment. All TMs required an open Work Order for implementation, functional testing, removal and post-maintenance testing. A 10 CFR Part 50.59 applicability check and safety evaluation, if applicable, were completed prior to TM installation. The inspectors determined that the applicability checks appropriately addressed the plant change. The use of a TM for longer than one operating cycle was strongly discouraged and required the General Manager, PNPP Department's approval to be extended. The inspectors verified that the three (3) open TMs were properly installed. Although, the TM process was implemented as written, the methodology used to control certain TMs (e.g., out-of-service annunciator windows) was unique and different from other plants. However, no compromise of regulatory requirements were identifie Two issues were identified during review of the TMs. Temporary Modification 1-99-0002 was not posted on drawing D-302-643 in the control room, Technical Support Center (TSC), and Emergency Operations Facility (EOF) during the implementation of the tag order. The second issue involved a missing Safety Evaluation (SE) (98-0003) for TM 1-97-0026. The SE and applicability check were not micro-filmed with the T Technical Specification 5.4.1.a requires written procedures to be implemented covering the applicable procedures in RG 1.33. Procedures for documentation control and procedure adherence are specified in RG 1.33, Appendix A. The failure to follow Perry Administrative Procedure (PAP)- 1402, " Temporary Modification Control,"
Paragraphs 6.7.5.c. and 6.11.1.1, were examples where the requirements of TS 5.4. were not met and was a violation. However, this Severity Level IV violation is being treated as a Non-Cited Violation (NCV), consistent with Appendix C of the Enforcement Policy. The licensee promptly initiated CRs 99-1802 and 99-1876 to address these issues and corrected the affected drawings. (NCV 50-440/99013-01(DRS))
J C Conclusions The inspectors concluded that TMs were being controlled in an acceptable manne Existing TMs were appropriately installed and tested. However, a NCV was identified involving the failure of Document Control Department personnel to follow written

procedures in posting a TM on control room, TSC, and EOF facility drawings and controlling a S E1.4 Calculations 1 Insoection Scope (37550)
The inspectors reviewed selected design calculations that were important to plant safety or had significance to probabilistic risk assessment (PRA) issues. The calculations were reviewed for accuracy and to verify that appropriate design inputs, assumptions, and calculation methods were use Observations and Findinas The inspectors reviewed several mechanical and welding calculations for adequacy of assumptions, completeness, and accuracy of conclusions. Although minor examples of a lack of attention-to-detail were observed, the methods used in performing and revising I design calculations were generally correct and appropriate. Methods, references, and inputs were clearly stated and open assumptions for new calculations were controlle The inspectors observed good documentation practices, such as, clearly stating the calculation purpose, listing verifiable design inputs, appropriate completion of calculation checklists, use of design review or alternate calculation, specifying verification methods, and resolving verifier comment b.1 Enaineerina Calculations to suoport TS SR 3.6.3. Mechanical calculation M51-013 calculated required compressor output to assure that containment hydrogen concentration levels remain below design basis. As described in TS bases B 3.6.33 and USAR Section 6.2.5.2.2, the M51 combustible gas mixing system was designed to operate following a LOCA. Technical Specification SR 3.6.3.3.2 required that surveillance tests be performed to verify that the M51 hydrogen gas mixing compressors can discharge a flow rate of 500 scfm into the drywell following a LOC As discussed in Section E7.1.b.2 of this report, the inspectors identified that calculation .
M51-013 had not been revised in a timely manner and incorporated into quarterly TS !
surveillance instructions (SVis) M51-T2003A and B. The calculation did not incorporate the results of flow measurement uncertainty and Calculation M51T09's potential diesel i generator (DG) frequency deviations. Because Calculation M51-013 had not been revised and incorporated into the current compressor performance test criteria, the test criteria was non-conservative. The licensee promptly issued CR 99-1892 dated July 29, 1999, and performed an operability determination (OD). In adoition, the required quarterly TS surveillance tests were placed on " hold" until the calculation could be revised and results incorporated into the surveillance tes I

of assumptions, completeness, and accuracy of conclusions. An earlier NRC inspection l and a PNPP self-assessment had previously identified electrical calculation weaknesses in terms of a lack of rigor in design inputs and conclusions. The inspectors observed that the licensee had taken several steps toward long term resolution. Improvements
'
were noted, as recent electrical calculation revisions, such as, PRDC-0006/02 (DCC-02)
showed improved documentation, clearly stating the calculation purpose, listing assumptions and verifiable design inputs, and specifying the verification metho Conclusions in most cases, the methods used in performing and revising design calculations for recent design changes were correct and appropriate.

pumps' surveillance tests, TS surveillance requirements, performance requirement calculations, USAR Section 6.3, CR 98-0568, " Deficient ECCS Technical Specifications," dated March 24,1998, and CR 99-1567, "HPCS Pump Failed Surveillance Test," dated June 7,199 _O_bservations and Findinas On July 26,1999, the inspectors observed that the design analysis in the USAR required significantly higher HPCS and Low Pressure Core Spray (LPCS) pump performance than that specified by TS Surveillance Requirement 3.5.1.4. When questioned by the inspectors, the licensee provided CR 98-0568 dated March 24,1998, which identified that the minimum performance requirements specified for all the ECCS pumps in TS Surveillance Requirements 3.5.1.4 and 3.5.2.5 were below the USAR design requirements. The licensee confirmed that the USAR design requirements were the appropriate requirement The inspectors' reviews of the ECCS pump performance calculations determined that surveillance test acceptance criteria were significantly higher than the TS surveillance

requirements and met the USAR design requirements. The inspectors also verified that l the latest performances of the surveillance tests documented that all of the ECCS l
'
pumps met both surveillance test acceptance criteria and design requirement Discussions with the operators revealed that the Operations staff had not been informed of the deficient TS surveillance requirements. Consequently, the inspectors concluded l
that administrative controls were not adequate to formally notify the operators of l deficient TS surveillance requirement l l
The inspectors were also concerned that the deficient TS surveillance requirements, which were initially identified on March 24,1998, had not been corrected in a timely manner. On January 14,1999, the corrective actions for CR 98-0568 were documented as complete based on preparation of a TS change request and supporting calculations, !
and the TS change request was ready for submittal to the NRC. However, the licensee l was not planning on submitting the TS change request until after August 1999, approximately 17 months from initial identification. The licensee's failure to correctly derive the TS surveillance requirements from the USAR analyses to assure that the necessary quality of systems and components was maintained as required by 10 CFR Part 50.36 was a violation. This Severity Level IV Violation was issued because the licensee failed to restore compliance by correcting the deficient TS surveillance requirements within a reasonable time frame after the deficient condition was identified, )
as required by Appendix C of the Enforcement Policy. (VIO 50-440/99013-03(DRS) l Conclusions j The inspectors concluded that the failure to correctly derive ECCS pump TS surveillance requirements from the USAR analyses was a violation of 10 CFR Part 50.36. The violation was cited and a response required as a result of the failure to submit the required TS amendment in a timelv manne E2 Engineering Support of Facilities and Equipment E2.1 Modification Supoort and Closecut Inspection Scope (37550)
The inspectors reviewed the methods used by the engineering staff to support the modification process. This included modification final review and closeout control Relevant procedures and records were discussed with cognizant licensee personne Observations and Findinos A review of the completed modification packages indicated that ample review was performed prior to preparing the design change, that satisfactory controls were evident in implementing design changes, and that final closeouts were completed in a timely manne .

The inspectors reviewed PAP-1608, " Corrective Action Program," dated June 3,199 The methods used to perform operability determinations were reviewed to verify the adequacy of controls and compliance with regulatory requirement The inspectors focused on engineering activities that provided direct support of plant facilities and equipment, and Engineering's support of the day-to-day activities of the plant's Operations and Maintenance staff. Examples of the types of activities reviewed included providing inputs to operability determinations, assisting in the resolution of CRs, providing acceptance criteria for surveillance testing, and providing technical -
consultation on maintenance activities, Observations and Findinas The inspectors found that PAP-1608 adequately described methods for controlling operability determinations. The Shift Supervisor (SS) made the initial operability determination on the CR initiation form. Subsequent evaluations to provide further analysis of the conditions were usually completed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The inspectors found that operability determinations were generally acceptable with sufficient detail, although two specific exceptions were noted, Unacoroved Accident Dose Calculation Method Used in Operability Determination On February 17,1999, the licensee identified a 135 gallons per hour (gph) leak outside containment from RHR relief valve 1E12-F036. Condition Report 99-0367 was initiated and immediate corrective action was taken by gagging the valve. Subsequently, the valve was removed as a part of a modification that removed the steam condensing mode of RHR from the plant desig The initial operability evaluation determined that the containment was inoperable because this leakage rate would cause all of the regulatory limits on accident exposure to be exceeded. The licensee had calculated that the control room limit would be reached at 60 gph, the offsite low population zone (LPZ) limit would be reached at 86 gph, and the site boundary dose limit would be reached at 100 gph. Based on this evaluation, the licensee reported this condition in a 1-hour phone call to the NRC per 10 CFR Part 50.7 Subsequent to the 1-hour phone call, the licensee performed new accident dose calculations for the as-found leakage based on the source terms and methodology contained in NUREG-1465, " Accident Source Terms for Light-Water Nuclear Power Plants." This new methodology removed much of the conservatism of Regulatory Guide 1.3. . These calculations showed that for the as-found leak rate, the accident

i
exposures would be below all of the regulatory limits. Based on these new analyses, the licensee retracted the 1-hour phone call report on March 18,199 At the time the leak was discovered, the plant's approved design and licensing bases methodology for determining source terms and calculating accident exposures, as described in USAR Section 15.6.5.5.1, was GL 1.3. Although the new methodology of NUREG-1465 was endorsed by the NRC, and there was a pending license change request to adopt the new methodology, at the time of discovery of the leak the design and licensing basis for the plant was still GL 1.3. At the time the 1-hour report was retracted and at the end of the 30-day time limit after discovery for submitting a Licensee Event Report, the license amendment still had not been approved. Therefore, the plant was "in a condition that was outside the design basis of the plant." In response to this discovery, the licensee initiated CR 99-1918 dated August 2,199 CFR Part 50.72 required that for "Any event or condition during operation that results in the condition of the nuclear power plant, including its principle safety barriers, being seriously degraded; or results in the nuclear power plant being:...(B) In a condition that is outside the design basis of the plant..." a licensee shall notify the NRC within one hour of its occurrence.10 CFR Part 50.73 required that for these same conditions, a licensee shall submit a Licensee Event Report within 30 days after the discovery of the condition. On February 17,1999, the licensee discovered a leak outside containment from the RHR system that constituted a serious degradation of the containment, a principle safety barrier. This was a condition outside the plant's design basis. Although a 1-hour notification to the NRC was initially made, the subsequent retraction was contrary to 10 CFR Part 50.72. The licensee's failure to submit a Licensee Event Report within 30 days of the discovery of this condition was contrary to 10 CFR Part 50.73. This is an example where the requirements of 10 CFR Part 50.72 and 10 CFR Part 50.73 were not met and was a violation. However, this Severity
_ Level IV violation is being treated as a NCV, consistent with Appendix C of the Enforcement Policy. This violation is in the licensee's corrective action program as CR 99-1918 dated August 2,1999. (NCV 50-440/99013-04(DRS))
b.2 Reoulatory Limits Used in Place of Desian Basis Limits Durina Ooerability Determination A program to limit leakage outside containment was required by TS 5.5.2, " Primary Coolant Sourcer Outside Containment." This program was implemented by PAP-1111
" Primary Containment Leakage Reduction for Systems Outside Containment,"
Revision 1, dated December 15,1992, Procedure / Instruction Change (PIC) No. 4, dated September 3,1998. The licensee's PAP-1111 identif;ed the administrative and analytical leakage limits as 5 gph and 10 gph, respectively. Both the administrative and analytical limits were described in USAR Section 15.6.5.5.1.2; the analytical limit (10 gph) was described as one of the bases (the leakage rate assumed for dose calculations purposes) for the design basis analyses of control room and offsite accident radiation exposure limits that were contained in USAR Table 15.6-1 On January 25,1999, the licensee discovered that RCIC relief valve 1E51-F017 was leaking outside containment at a rate of 36 gph. The licensee evaluated the RCIC relief valve leak and determined that the leakage was above the analytical limit (10 gph) for leakage outside containmen _ _ _ _ _ _ _ _ _ _ _ _ _ _

In performing the operability determination, the licensee compared the as-found leakage outside containment (36 gph) to the leakage rates which corresponded to the regulatory limits rather than the USAR design basis limits. The licensee had previously calculated the amount of leakage outside containment that would cause accident exposure to exceed the regulatory limits contained in 10 CFR Part 50, Appendix A, Criterion 19 and 10 CFR Part 100.11. The limiting exposures in all cases were for thyroid exposure. The control room 30 rem limit was reached at 60 gph leakage. The low population zone (LPZ) 300 rem offsite dose limit was reached at 86 gph leakage and the 300 rem site boundary dose limit was reached at 100 gph. Since the as-found leakage outside containment was less than any of the regulatory limits, the containment was considered operable and no reports were made per the requirements of 10 CFR Part 50.72 and 10 CFR Part 50.73. Condition Report (CR) 99-0174 was issued and the valve was promptly replace The inspectors questioned whether the operability determination should have been made comparing the as-found leakage rate to the USAR design basis limit of 10 gph (the analytical limit assumed in dose calculations) contained in USAR Section 15.6.5.5.1.2 and Table 15.6-15. Such a comparison would have shown the containment leakage to exceed the plant design basis and a 10 CFR Part 50.72, one hour notification to the NRC would have been require The inspectors' concern was based on specific statements identified in the Code of Federal Regulations, where 10 CFR Part 50.72(b)(1)(ii) requires that for "Any event or condition during operation that results in the condition of the nuclear power plant, including its principle safety barriers, being seriously degraded; or results in the nuclear power plant being:...(B) In a condition that is outside the design basis [ emphasis added]
of the plant..." a licensee shall notify the NRC within one hour of its occurrence. The term " design basis" was defined in 10 CFR Part 50.2 as "...that information which identifies the specific functions to be performed by a structure, system, or component of a facility, and the specific values [ emphasis added] or ranges of values chosen for controlling parameters as reference bounds for design. These values may be...(2) requirements derived from analyses (based on calculation and/or experiments)
of the effects of a postulated accident for which a structure, system, or component must meet its functional goals." in this instance, the " design basis", i.e., the " requirements derived from analyses...of the effects of a postulated accident", were the calculated accident dose limits or " specific values" in USAR Table 15.6-15, and the " functional goals" were the above described regulatory limits these values were required to mee Within this definition, the leakage condition discovered by the licensee was outside the design basis, and the containment leakage should have been reporte Generic Letter 91-18, "Information to Licensees Regarding NRC Inspection Manual Section on Resolution of Degraded and Nonconforming Conditions," Revision 1, dated October 8,1997, gave further guidance on making operability determinations that was consistent with the regulations. It referenced NRC Inspection Manual, Part 9900,
" Operable / Operability: Ensuring the Functional Capability of a System or Component",
which in Section 5.3, stated, "According to the definition of operability, a safety or safety support system or structure must be capable of performing its specified function (s) of prevention or mitigation as described in the current licensing basis, particularly the TS bases or FSAR." " Current licensing basis" was defined in Section 2.1 as "...the set of

.
.
NRC requirements applicable to a specific plant, and a licensee's written commitments (emphasis added] for assuring compliance with and operation within applicable NRC requirements and the plant-specific design basis [ emphasis added]..." In this case, the
" written commitments" to the " plant specific design basis" were the accident dose limits committed to in USAR Table 15.6-15 and the leakage limits upon which they were '
base i in response to the inspectors' concem, the licensee generated CR 99-1888 dated July 28,1999, which documented both the licensee's and the inspectors' concerns. The licensee's position, as stated in this document, was that the containment design basis and the associated "specified safety function" were to limit doses to 10 CFR Part 100, as described in USAR Section 6.2.1.1, No mention was made in this document of the 10 CFR Part 50, Appendix A, Criterion 19 control room dose limits. However, Regulatory Guide 91-18 defined "specified safety function"in Section 3.3 as follows,
"The definition of operability refers to capability to perform the "specified functions." The specified function (s) of the system, subsystem, train, component, or device (hereafter referred to as system) is that specific safety function (s) in the current licensing basis
[ emphasis added] for the facility." As previously described, the " current licensing basis" is also defined in this document as the " licensee's written commitments for assuring compliance with and operation within applicable NRC requirements and the plant-specific design basis." The analyzed dose limits contained in USAR Table 15.6-15 and their corresponding leakage limit,10 gph, were the " plant-specific design bases for assuring compliance with NRC requirements" of 10 CFR Part 100.11 and 10 CFR Part 50, Appendix A, Criterion 1 In addition to the January 25,1999, RCIC relief valve leakage event, a second example occurred at PNPP where operability and reportability were evaluated against the accident dose regulatory limits rather than the design basis limits contained in the USAR. This event occurred on February 17,1999, and is described in Section E2.2. of this repor The NRC has decided to further evaluate this issue and sp'ecifically address:
(1) whether the licensee's use of accident regulatory limits contained in 10 CFR Part 50, Appendix A, Criterion 19 and 10 CFR Part 100.11, which were used in place of the licensing commitments of the USAR during an operability /reportability assessment complies with NRC regulations; and (2) to address whether the licensee complied with NRC regulations 10 CFR Part 50.72 and 10 CFR Part 50.73 when they failed to notify '
i the NRC that they were outside the USAR specified design basis limits. Pending completion of the NRC's review, this concern is considered an unresolved ite (URI 50-440/99013-05(DRS))
b.3 Verification of HPCS Pumo's Dual Role Caoability The HPCS system was designed to inject to the reactor for two basic functions. The first function was injection over the full spectrum of LOCA breaks, including large break LOCA, where the reactor pressure would be low. The second function was as backup for the RCIC system for loss-of-feedwater (reactor isolation) events, where the reactor pressure could be as high as the main steam safety / relief valves' (SRVs') setpoin .
.
Amendment No.101 to the Perry Technical Specifications authorized a relaxation of the SRV setpoint tolerance from 1% to 3% As a result, there was the potential that the reactor could be at even higher pressure for reactor isolation events. The licensee recognized that the HPCS pump ASME Code Section XI surveillance testing that was being performed represented only its low pressure performance requirement by using a reference point at the low pressure end of the pump curve. In order to assure that the testing would also verify HPCS's capability to fulfill its RCIC backup role, the licensee generated Calculation E22-29," Evaluate HPCS Pump Performance Acceptance Criteria Associated With the Higher Potential Reactor Pressure," Revision 4, DCC-003, dated April 19,1999, which demonstrated that if the low pressure surveillance test acceptance criteria were met, the pump would also be capable of meeting,the RCIC backup high pressure performance requirement Conclusions Overall, Engineering's support of the facilities and equipment, and its involvement with and contributions to the plant's day-to-day operations, were satisfactor Although two specific exceptions were identified, the inspectors concluded that the licensee's operability determination process was effective. Operability determinations and the supporting evaluations were acceptable. However, a NCV was identified due to the licensee's use of an unapproved accident dose calculation method, which resulted in not meeting the requirements of 10 CFR Part 50.72 and Part 50.73 for leakage outside containment. In addition, the licensee's use of regulatory limits in place of design basis limits during an operability determination was considered an unresolved item pending further NRC revie E2.3 Operatina Experience Proaram Inspection Scope (40500)
The inspectors reviewed the methods for obtaining and using industry operating experience. This included industry information obtained from outside sources including the NRC, industry groups, vendors and other licensees for the operating experience program. The inspectors interviewed cognizant licensee personnel about the industry experience progra Observations and Findinos The licensee's PAP-1607, " Operating Experience Reports (OER) Program," Revision 1, assigned responsibilities for the receipt, assessment, dissemination, and the initiation of corrective actions for industry experience information. The inspectors verified the dissemination and availability of operating experience (OE) by interviews with the electrical maintenance manager and other observations. The inspectors verified that the licensee adequately implemented corrective actions for operational experience feedback as outlined in the procedure. The inspectors also verified that OE was incorporated into the operator training program as evidenced by the usage of current industry events into the lesson plan (OER 15-96, inappropriate Operator Actions During Low-Power Operations).

i b.1 incomplete Control Comolex Chiller Trio CRs Evaluation Condition Report 98-2649, " Control Complex Chiller Motor Trip on High Temperature,"
dated December 25,1998, documented a trip of control complex chiller A on January 13,1999, due to a high motor temperature. This was the fourth occurrence of this trip in thirteen months. The cause was identified as a failed motor temperature j sensor The remedial action was to remove the motor temperature sensor trip from both the A and the B chillers' control logic, thereby restoring their reliabilit ]
Extensive documentation was provided in the CR package that addressed the mode of failure, cause of failure, maintenance rule applicability, and the proposed corrective action. However, none of the documentation discussed the relevance of this trip function to the safety function of the control complex chillers, or how removing this function from the control logic would affect the chillers' safety functio Through discussion with the responsible engineer, it was determined that the equipment in question was commonly used in commercial applications, and that this trip was a standard vendor-supplied feature intended to protect the equipment. While this trip function would be desirable for most commercial applications, in this safety-related application, it was counter to the system's safety function. Therefore, from a safety system reliability perspective, it was not only permissible to remove this trip function, but ,
desirable. However, the documentation was incomplete in that it did not address this I most pertinent point. This was an example of inattention-to-detail in the CR documentatio j Incomolete ECCS Strainer Debris Calculation Documentation i

This document indicated that all of these assumptions were actually supported by other calculations or by testing; therefore, there were no operability concerns. The licensee verbally committed to revising the calculation to include these bases for the assumptions. This was considered an example of inattention-to-detail in generating engineering documentatio c. Conclusions Two examples were identified where the document authors were not attentive to assuring that the documents contained the appropriate details.

The inspectors confirmed for several individuals that they had been trained to perform and review operability determinations, safety screenings and safety evaluation During this review, the inspectors noted that there were some weaknesses with record-keeping, e.g., the inspectors found that an engineer's qualification card was issued before the Perry Training Section Manager signed as required. However, the inspectors noted that the engineer's supervisor and engineering manager had both .
signed as required previous to issuance. The licensee entered the weakness into the corrective action program (CAP) by initiating CR 99-1822 on July 19,199 .

as these systems were rated among the top seven train contributions to plant ris The inspectors observed that the safety-related areas and equipment material condition were good. However, the inspectors noted the following three conditions that existed for long periods indicating some lack of attention-to-detail on the part of plant staf Safetv-Related Eauioment Labelina: The safety-related HPCS ESW pump strainer imtrument valve No.1P45-F563 had been identified on March 2,1996, as missing it's identification label and a temporary paper tag had been affixed to the valve bonnet. The valve was entered into the plant tag corrective action process program as 1-96-189, in order to install a metal component label as required by plant label procedure PAP-1407. However the inspectors identified that the permanent label for this valve had not been installed in over 3 year The inspectors interviewed staff and found that it was generally common knowledge that permanent labels were expected to be installed in a timely manner of less than 6 months (PAP-1404, Section 6.1.1.2, "Information Tagging Rules"). Licensee personnel informed the inspectors that the label had been lost from their label replacement database tracking system and therefore the routine bi-annual safety label audits had not captured this issue. Licensee personnel informed the inspectors that the ESW label would be replaced into their label monitoring database and installed at the earliest opportunit Unsecured Eauioment in ESW Safety Sianificant Area: During the welkdown of ESW equipment in the safety-related ESW pump house, inspectors noted that an air compressor was not secured to prevent it from sliding into safety-related equipment in the event of a seismic event. The inspectors determined that the equipment had baon there for 5 days and considered that because routine plant personnel walkdowns of the safety-related ESW pump house on a daily / shift basis did not identify this highly visible piece of equipment and promptly correct this situation, that this indicated a lack of attention-to-detail on the part of the Operations personnel. The inspectors observed that the system engineer took i prompt action to identify this situation to the control room and correct the situatio l

Although the gaps found during the walkdown were not a concern at this time, a weakness in plant safety significant hanger monitoring procedures was identified by the inspectors. There did not appear to be sufficient quantitative evaluation criteria to assure that the plant criteria contained in design basis calculations for ,
safety significant hanger supports was met. The licensee issued CR 99-1981 !
dated August 11,1999, to address the issue, Conclusions The inspectors concluded that, in general, the system engineers were providing good plant technical support and were knowledgeable about Maintenance Rule requirement The inspectors also concluded that plant housekeeping and material condition of safety-related equipment observed was good; there were a few areas where a lack of attention-to-detail was noted. A procedural weakness for monitoring safety significant hangers was ider,tified by the inspector E6.2 Review Committee Activities Inspection Scoce (40500) l
The inspectors evaluated the review committees' implementing procedures, minutes, audits, and followup actions of items identified by the committees. The inspectors j discussed the functions, findings and activities of these committees with cognizant i licensee personnel. In addition, the inspectors attended several review committee meeting Observations and Findinas The inspectors reviewed PAP-0103, * Plant Operations Review Committee," Revision 6, which defined the activities and responsibilities of PNPP's On-site Review Committe The inspectors also reviewed " Company Nuclear Review Board Policies and Practices,"
dated March 9,1999, which defined the activities and responsibilities of PNPP's Offsite Review Committee. The inspectors reviewed recent minutes of each review committee's meetings to evaluate the activities and decisions made. The licensee's Quality Assurance group periodically audited both the Plant Operations Review Committee and the Company Nuclear Review Board; however, no significant issues were identified during recent audits. Additionally, the inspectors observed the morning management meeting where management reviewed recently issued CRs. The management review generally addressed the relevant issues and reevaluated the category level. The format of the meeting encouraged inter-departmental communications that were effective in promoting active staff participatio r

b.1 Corrective Action Review Board The inspectors reviewed the controlling procedure for the Corrective Action Review Board (CARB), selected records of meeting minutes, and a trending corrective action performance indicator for plant CRs. The inspectors attended a CARB meeting held on July 14,1999, and observed that this meeting was conducted in accordance with procedural requirements and in a professional manner. CARB members raised pertinent questions and exchanged real time knowledge about issues that were discussed. After an in-depth discussion, the committee identified areas where a CR required further development. The CARB rejected the submitted CR until the identified areas were completed, b.2 Corrective Action Proaram (CAP) Continuous Imorovement Group The inspectors observed that a CAP Continuous improvement Group (ClG) had recently been established at PNPP to improve the effectiveness and efficiency of the CAP. The inspectors reviewed the CIG charter and attended a CIG Committee meeting during the inspection. The issues addressed in the meeting indicated the committee reviewed substantial corrective action issues in depth, such as CR quality, and provided greater efficiency in monitoring plant problems by improving CR trend codes processes. In order to evaluate CR quality, the CIG developed a CR quality index scorecard and graded 20 randomly chosen safety CRs against the desired criteria. Five of the CRs were also cross graded by more than one supervisor and the generated scores ,
compared to monitor whether CR expectations were consistent across plant discipline { Conclusions '
The inspectors concluded the review committees effectively performed their duties of maintaining periodic review of activities, safety issues and evaluations. The inspectors concluded inter-departmental communications were effective in promoting active staff participation. The inspectors also concluded that the establishment of the CIG demonstrated a rigorous attempt by the licensee to improve the plant CA E7 Quality Assurance in Engineering Activities E7.1 Corrective Action Proaram Inspection Scoce (40500)
The inspectors assessed the CAP through CR reviews and by interviewing cognizant personnel about the corrective action and CR processe Observations and Findinas A detailed review of CRs, problem identification forms (PlFs) and ACTON ("act on")
engineering actions items was performed. The inspectors determined that the CRs provided a clear problem description and, in most cases, corrective actions were appropriate for the problem significance. Overall, the inspectors found that the

threshold for identifying problems was relatively low and that personnel interviewed .
appeared willing to identify problems through the CR process. The establishment of the
{
ClG, recent efforts to prioritize the CR database backlog and the trending /binning of '
CRs demon,strated that effective methods were being applied by the licensee to improve the CA The licensee stated that engineering work load was higher than desired and timeliness of issue resolution within the engineering organization was a known weaknes Although actions were being taken to improve the process, the inspectors observed I some instances where attention-to-detail, stand-alone documentation (without requiring l recourse to the originator), depth of corrective action investigation and timeliness of !
fixing identified plant problems were found. These areas were considered by the ;
inspectors to be known problem areas that will require a continued management effort i for resolution and are discussed in Section E7.2 of this repor I Use of Alternative Databases The licens"o assigned CR backlog reduction a high priority and had recently completed a signific effort to re-prioritize all open action items in the CR database. However, the inspectors determined that the licensee also used other databases (e.g., the ACTON and the Operations Label Replacement databases)in addition to the CR dat@e to track and manage work items. The inspectors identified some examples wheie, the use of the ACTON database resulted in items with conditions adverse to quality being entered into the database without the proper CAP resolution. Although a significant effort to re-prioritize the CR database was completed, the licensee could not demonstrate to the inspectors that the other databases were effectively managed and controlled. As a result, the inspectors were concerned that the other databases could contain additional examples of conditions adverse to quality that were not appropriately identified and that adequate management overview of all past and present action items contained in these databases were not effectively manage Based on inspectors' questioning, the licensee investigated five NSSS ACTON items, it was found that two of the items had been completed but had not been closed out and two were considered safety-related enhancements to the plant rather than required items. The remaining item was safety significant and had not been corrected in a timely manner (see Section E7.1.b.2). Although most of these ACTON database items were identified as not safety significant, the fact that neither plant management or the cognizant engineer assigned to the ACTON item knew this prior to the inspectors'
questioning was considered a weakness in the program. As a result, the licensee issued CR 99-1892 dated July 29,1999, to address action items within the ACTON database. The inspectors were satisfied that this matter would be addressed; however, the inspectors concluded that to ascertain, monitor and track the total backlog of action items established at the plant, management attention was required to ensure that only appropriate issues were entered into the attemative database b.2 Timeliness of Revisino Calculation M51-013 & Associated Values in SVis M51-T2003A/B On February 19,1987, a field change request was generated that stated the acceptance criteria for SVis M51-T2003A/B did not meet the GE specification. The licensee did not
'
,
,
initiate any changes to the calculations or associated SVI values. As a result of the licensee researching similar calibration issues identified by an NRC Inspection conducted in 1997 (Inspection Report 50-440/97201), PIF 97-0165 was generated but was closed out as ACTON database item 97-050 without revising the calculation and associated SVis. This issue was placed into the ACTON database in 1997 without the calculation's associated SVis being placed on hold. At the time of this inspection, the inspectors observed that work had not been initiated on the ACTON database item. As a result, an identified safety-related calculation was not corrected in a timely manner and was considered a NCV as described in Section 1.4.b.1 of this repor RFO7 Modifications & CRs Closed Out to the ACTON Action Item Database Under the current safety-related DCP modification process, a modification may be closed if the remaining items such as non-critical procedure revisions are placed within the ACTON database as action items. As a result, if the original CR initiating the modification was written in a manner such that the completion and closure of the modification satisfies the action item, in essence the CR becomes closed out to the ACTON system without allitems completed. The inspectors noted that plant modification procedures did not state that safety-related modifications could be closed out to the ACTON database prior to completion of all ancillary plant change action item After discussion with licensee staff a desktop administrative guide was produced which indicated that this was an acceptable program practice. Because the modification program procedures did not specifically address what DCP items could or could not be placed into the ACTON system prior to plant change closure, and as ACTON items were not closely tracked and prioritized, the inspectors considered this another example of corrective action items that were not presently under close management review and contro Conclusions The inspectors concluded that the majority of plant problems were identified, assessed, and had appropriate corrective actions assigned. Establishment of the CIG, recent efforts to prioritize the "CR database" backlog, and the trending and binning of reports demonstrated that effective methods were being applied by the licensee to improve the CR action item program. The inspectors concluded that the ACTON database was not under effective management review and control. Therefore, there appeared to be a lack of an integrated, well managed program with management overview for all past and present plant action items contained in this database. The inspectors concluded that continued effort would be required by the licensee to address and resolve this issu E7.2 Corrective Action Trendina i Inspection Scope (40500)

. Observations and Findinos Plant personnel generating a CR were required to chose a trending code most applicable to the CR. The QA trend coordinator then tracked, searched and sorted CRs by codes to identify plant trends. Upon identification of an adverse trend, an adverse trend CR was issued to identify if additional corrective actions were necessary. The inspectors reviewed several trend reports and determined that the reports were of good quality. This was due, in part, to having a QA trend coordinator that was knowledgeable about the plant and in.timately involved in site corrective action panels. Staff commitment to the value added by trending CRs was demonstrated by the fact that both operations and maintenance management had started proactively trending department CRs on a weekly basis. By alerting work crews to trends and lessons leamed from the previous weeks CRs, management anticipated quicker turn-a-rounds in averting negative practices and trends within these department The inspectors also noted that during RFO7, site and human performance error CRs had been graphed and used to determine when plant stand-downs to address significant 1 issues should be deployed. The effectiveness of the stand-down was assessed by tracking when issue CRs returned to baseline. The licensee also planned to use the RFO7 identified contractor human performance error trends for future outages by preplanning plant stand downs for identified issues into the upcoming RFO8 outage schedul The inspectors reviewed several QA effectiveness reviews. The licensee had identified i several instances where corrective actions were ineffective and additional actions were l assigned to these problems. The inspectors determined that the QA reviews were a I good tool for identifying additional corrective actions that may be warranted,
'
i From its review of self-assessment recommendations and audit findings, the inspectors noted some general themes which paralleled the inspectors findings on corrective j actions. Attention-to-detail problems, stand alone documentation without requiring 1
, recourse to the individual originator, and timeliness of fixing identified plant problems ,
l were areas that will require continued effort for resolution.
, Conclusions
,
The inspectors concluded that appropriate mechanisms were in place for self-assessments and quality assurance trending activities and that a number of plant and I crganizational problems were being identified. The licensee's trending program and j effectiveness reviews contributed to identifying repetitive problems and inspectors l concluded that QA investigations were accurate and thoroug E7.3 Audits and Surveillances Inspection Scope (40500)

and the Perry Plant Program Audit Schedules for 1997,1998,1999, and 2000. The attacned document list identifies the other quality assurance audits that were reviewe Observations and Findinas The inspectors found acceptable Nuclear Quality Instruction NQl-1801," Audit Program Control," Revision 1, which specified the process for the QA program to accomplish the audits. The inspectors' review of selected QA engineering audits revealed that audit findings and recommendations were entered into the CAP by the proper initiation of CRs. The Company Nuclear Review Board was the licensee's offsite safety review committee which reviewed all QA audit schedules and the resulting audit The inspectors conducted interviews with the QA manager, the Directors of the Nuclear Engineering Department, Perry Services Department, and the Perry Power Plant Department. These individuals stated that the QA program was effective in identifying problems and recommending corrective actions, and that line organizations such as engineering did not minimize QA findings. These individuals also stated that line organizations worked well with QA sometimes nequesting QA audits, in problem area Conclusions The inspectors concluded that the audit process met 10 CFR Part 50, Appendix B, requirements. The QA audits were identifying problems and the licensee was taking appropriate corrective action E8 Miscellaneous Engineering issues (92903)
. E8.1 - LClosed) Violation (50-440/98011-01(DRSik The instantaneous trip function for the emergency closed cooling pump motor's circuit breaker (EF1804) was not tested in-accordance with design requirements. The as-tested acceptance criteria values were calculated by the technician performing the test at values higher than the allowable band. This resulted in the breaker's instantaneous pick-up value not being tested within the required design parameters. The inspectors reviewed the licensee's corrective actions addressed in letter Number PY-CEl/NRR-2311L dated August 13,199 i Corrective actions included the following: an engineering evaluation determined that the as-tested values were satisfactory and the breaker would operate as required; a review was conducted of similar tests and no additional discrepancies of this type were identified; electrical maintenance personnel completed generic electrical instruction (GEI) training on the requirements of breaker testing; and the associated gel was scheduled to be revised to include a table of acceptance criteria test values for testing the instantaneous trip function. The inspectors concluded that the licensee's corrective actions were acceptable. This item is close ,
