The inspector reviewed the licensee's document control program required by references (a) _through (g) to determine if the program had been. estabitshed in accordance with regulatory requirements, industry guides and standards, and technical specifications. The following criteria were used during this-review to determine the overall acceptability of the established program:

-

Administrative controls had been established for drawing issuance, drawing change review, obsolete drawing _ control, and as-constructed and as-built drawing updatin Administrative controls had been established for maintenance of indices for drawings, manuals, Technical Specifications, FSARs, and procedure Administrative controls had been established which assign specific responsibilities for drawing and document control program The following documents were reviewed to verify that these criteria had been incorporated into the licensee's QA program for document controls:

Administrative Policy Manual (APM) 2.1, Document Control, Revision 8 APM Administrative Instructions for Permanent Station Procedures, Revision 23 QA-100 Preparation and Issue of QA Procedures, Revision 9 QA-107 Temporary Procedure Changes, Revision 2 QA-501 Placing, Reviewing, and Verifying QA Requirements on Station Procedures, Revision 8 SD 2.1.5 Drawing Distribution and Control, Revision 25 SD 4.2.1 Development, Approval and Use of Station Procedures, Revision 22 The inspector reviewed document control surveillance reports performed since the previous NRC inspection in this area. These surveillance reports identified one substantial weakness in the document control area related to vendor manual control. The inspectors review of vendor manuals identified that some field manuals had not incorporated recent revisions, although manual revisions were accessible to those personnel whose job function would require use of these manuals. Vendor manual control had been identified as a problem throughout the Duke Power system. The licensee has assigned a

--

..

'

task force to review vendor manuals and update these on a page by page basis. This effort, The Vendor Manual Upgrade Program, was being performed at each site. Currently, the task force was assigned to Oconee Nuclear Station. The inspector reviewed a letter dated September 22,1986, File

, Number CN-114.89, from the Catawba Station Manager which stated that the

(Weekly and Quarterly)

The above listed surveillances were reviewed for proper surveillance intervals, compliance to procedure, meeting acceptance criteria, adequate management review, and meeting TS requirements. The inspector also ques-tioned various members of the plant staff about specific surveillance and calibration program During the review of the quarterly surveillance of pressurizer heater capacity, the inspector noted that current values for an individual heater bank varied by more than 200 amperes from one reading to the next. The

. licensee could not explain this variation. However, all readings in this area met the acceptance criteria.

l l The inspector reviewed various pump surveillance data back to 1984 for i

Unit 1 and back to 1985 for Unit 2. No deficiencies were identified but the inspector noted that during the Unit 1 outage some pump tests were allowed ,

to slip towards the end of the 1.25 extensio l l

The inspector noted that some surveillance test procedures do not include the time that the test was completed. This .becomes very important if the plant wishes to take credit for the time extension on shorter interval surveillances. An example of the 1.25 extension, for weekly surveillances,

- would be the one _ day and eighteen hours allowed extensio The exact time becomes critical if the plant exceeds the eighth day and wishes to take credit for the eighteen hour Within this area two-violations.and one unresolved item were identified and are discussed in the following paragraph Use of Non Calibrated . Instrumentation for Technical Specification Required Surveillance TS paragraph 4.9.4.2.D.1 states that the reactor building containment purge system shall be_ demonstrated operable at least once per 18 months by. verifying that the pressure drop across the combined hepa filters, carbon absorber banks, and prefilters is less than eight inches water gauge while operating the system at a low rate of 25,000 CFM 110% (both=

exhaust fans operating).

Procedure, PT/1/A/4450/010 Containment Purge Filter Train Performance Test, dated August 28, 1986, was performed to satisfy TS 4.9.4.2. The test data Section 10.2 Pressure Drop Across the Filters-U-Tube Manometer,-thus indicated that a U-Tube manometer would be used instead of the installed magnehelic (AP Detector). The magnehelic was used to perform this surveillance test. The inspector _ discussed this discrepancy with the performance engineers. .They were aware of the problem and had already modified the surveillance procedure to require use of the U-Tube manometer for the AP reading. They also stated that a plant modification request was generated to allow for connection of the manomete Further discussion with the performance engineer indicated that connection of the manometer would have taken too much time, so it was decided to use the process instrumentation for the test readin Through discussions with another performance Engineer, the inspector was informed that an accuracy check of the magnehelic was made using a U-Tube manometer, at a later dat The inspector contacted I&C personnel and verified that.the process instrumentation, magnehelic, used in the surveillance test was not included in the plant calibration progra The use of non calibrated process instrumentation for TS required surveillance is identified as violation 50-413/86-45-01, Failure to Use Calibrated Instrumentation for Technical Specification Required Surveillanc Inadequate Procedure for the Nuclear Service Water Valve Verification TS paragraph 4.7.4.a states that at least two nuclear service water loops shall be demonstrated operable at least once per 31 days by verifying that each valve (manual, power operated, or automatic)

. .

servicing safety-related equipment that is not locked, sealed, or otherwise secured in position is in its correct position. Six manual valves, in the seal water supply to the nuclear service water pumps, are not included in the monthly valve position verification surveill anc The inspector reviewed procedure PT/1/A/4400/02C, Change 7, and found that the following valves 1RN-C21, 1RN-C22, 1RN-21, 1RN-22, 1RN-23, and 1RN-25 are not included in the monthly valve surveillance. These valves are associated with filtering and supplying seal water and cooling water to the nuclear service water pumps and motors. The pump

. seal water ir.jection valves, located just prior to the pump seals, are included in the valve verification surveillance. The utility has recogrized the need for the seal water supply but not the need for the seal water syste The inspector discussed this discrepancy with plant staf They maintain that_ an operator verifies seal flow to the running pump twice a day and that this more than meets the surveillance requirements. The inspector maintained that if the standby pump (s) auto start with inadequate seal flow the pump seals, bearings and motor could be damage There are no alarms in the control room for inadequate seal flo The operations training manual, nuclear service water (RN) handout, on Page 31 of 78, REV 00/04-01-86/GLM, Section 2.2.0.3a' states that each RN essential header provides flow to a redundant set of safety related components and systems. The RN pump motor cooler, strainer, and pump seal injection are listed as essential header component The plant has already acknowledged the fact that this is a safety related system. Licensee oversite in not including these valves in the monthly valve verification surveillance is identified as violation 50-413/86-45-02 and 50-414/86-48-01, Failure to Provide Adequate Procedure for Nuclear Service Water Valve Verificatio (d) Variation in the Effective Full Power Day (EFPD) 31 Day Surveillance Data -

'

TS paragraph 4.2.2.2.d.1.6 required that the surveillance to measure core power distribution be completed once per 31 EFP Completed surveillances reviewed by the inspector indicates that the EFPD value was not taken at the same time as the incore flux map and excore power level readings. This indicates that the EFPD value was not reliable for insuring the 31 EFPD surveillance is completed as required.

.

The following data needs to be clarified by plant staff. On April 24, 1986, the recorded EFPD value was 265.8 EFPD, System Boron was 184 parts per million boron (PPMB), and plant power level was at 99.6% full power. The next recorded EFPD value taken on June 2,1986, was 296 EFPD, system boron was 75 PPMB and plant power level was at 100% full power. The total time between surveillances was 39 days. The boron burnout was 109 PPMB and would appear to indicate approximately 40 days of full power operation. There appears to be a discrepancy between boron reduction which is relatively linear for core burnup and total accumulated core burnup, which was stated to be 30.2 EFPD. The plant staff needs to document that during the time period from April 24, 1986 until June 2,1986, the total accumulated EFPD was only 30.2 EFPD as recorded. Until the plant staff documents the total EFPD for this period and the NRC reviews the documentation, this item is identified as Unresolved Item 413/86-45-03, Variation in the Effective Full Power Day (EFPD) 31 Day Surveillanc .

The above reference documents comprise the regulatory basis of the Catawba Quality Assurance (QA) audit program. The programmatic and some portions of the implementation aspects were examined in NRC Inspection Report No /85-49 and 50-414/85-50 dated January 10, 1985. The licensee stated that the upper and lower tier documents that implemented the QA Audit program had not been altered significantly since the issuance of the above inspection repor During the course of this inspection, the inspector examined the validity of the audit program's implementation using aspects of the above reference documents as criteri The following audits were reviewed by the inspector:

Construction / Modification Department (CMD) has been in operation at Catawba in their present form for approximately six month Previously, CMD was Duke Construction and they had operated under different regulatory rules during the building of the plants. At the time of this inspection, CMD was to be operating under the site's Nuclear Production Procedure The inspector was told that CMD was proposing a separate set of procedures for their operatio Under the Duke audit program, unresolved items (UI) which are identified in audit reports may or may not be deficient conditions pending additional information and evaluation. The UI were tracked by site compliance but the audit program required no response from site groups which were involved with the UI. Some site groups would respond to the UI by sending followup information to compliance personnel who, in turn, would notify the corporate auditors that the item may be ready for closur The inspector investigated four VI to see whether or not the listed conditions were accurate, were deficiencies, required immediate action at the time of the corporate audit, and were being acted upon by site personnel. The investigation revealed the following:

UI 5 of audit NP-86-6 (CN) indicated undocumented grace period frequen-cies for preventive maintenance. There was no administrative procedure documenting the stated grace period of 50 percent. The Duke auditor had inspected to a portion of reference (g) and followed up on this aspect to the degree necessary. Region wide, the typical grace period or tolerance to a frequency is more in line with technical specifica-tion tolerance of 25 percent. As stated by site production personnel, administrative procedure would be changed to state a preventive maintenance performance toleranc VI 7 of audit NP-86-6(CN) indicated a problem following a weld proce-

- dure for socket welds. The same Duke auditor had previously identified difficulties with procedural adherence which resulted in a comment in an earlier audit. This audit finding escalated the finding to a U Both CMD and Nuclear Production were aware of the auditor's concern but had not taken action on the item; there appeared to be confusion between the groups as to who had action on the ite Site compliance personnel had assigned Nuclear Production action on the item but Nuclear Production thought that CMD had the action. CMD had addressed the issue in a memo when the item was at the comment level (no action taken to correct the procedure) but did not inform compliance of the memo; CMD was unaware of the UI. The Duke auditor's identification of the VI was timely with the additional research he performe The NRC inspector independently evaluated the QC inspection points which would prevent improper socket weld fitup and found that there was a high probability that QC would find the defective weld joints prior to finalizing the weld (QC had found 3 instances in the last two years).

The inspector discussed the issue with CMD and CMD was convinced that a procedural change was in order to aid the welders in fitup require-ments. There was a good likelihood that the Duke auditor would have obtained the fix with the U ,

UI 8 of audit NP-86-6(CN) identified a concern -with a licensing commitment. The licensee had committed to perform TDI Diesel Generator Maintenance in operating license letters in 1984. As stated by the compliance / licensing group on site, the commitment to check diesel generator pedestal bearing oil level was inadvertently dropped from the final, accepted licensing letter and that the oil level check was not-procedurally described on site. Due to the VI, site personnel stated that the oil level check had been picked up in site procedures. Duke audit personnel are still investigating the ite UI 6 of audit NP-86-6(CN) identified some rigging problems on sit The problems were as follows:

CMD personnel rigged a 20 inch diameter flange off of a eight inch safety related pipe without any prior analysis for potential damag No site procedures were available to provide rigging instructions except a temporary shielding procedur A rigging review to be performed by site planner war not docu-mented as required by procedur It was stated by the licensee that prior to this inspection such rigging problems had been identified as a non conforming condition and evaluated via the site's corrective action system. This post lift evaluation did not occur in this instanc Although no analysis occurred, the Duke auditor who observed the lift and talked with site personnel about the parameters of the potentially deficient conditions did not choose to make the issue a deficienc According to site personnel, no evaluation of lift had been made since the event was made a U The procedure (MMP 1.0) that the planner used to perform the rigging review was interpreted by the planner that if he felt no rigging instructions were required, he did have to address it on the work request. CMD personnel, who were not required to get the work request changed when the job sequence was changed, opted to do the lift with riggin Site personnel had not corrected the procedure that the planner used to perform the rigging review nor had the site issued a rigging procedur The personnel involved with the actual work performance were not required to provide input during the planning phase of a proposed jo ,

The compliance group had identified the planning grcup as the respon-sible section for resolving VI 6. Per disct.ssions with the planning group, it was thought - that mechanical maintenance had the actio Again, as with UI 7 (in light of no VI written response being required), attention to this VI had low priority (audit issued in April of 1986) and the action group was ill define Due to potential significance of the rigging problems in this licensee identified issue and the multiple actions required, this will be an inspector followup item. Until site personnel and Duke auditors evaluate the lift even" identified in the UI, the need for rigging procedures, and the need to change the manner in which rigging reviews are performed, this is identified as inspector followup item 50-413/

86-45-06 and 50-414/86-48-03, Unresolved Item Resolutio The inspector investigated how NRC Information Notices (IN) were handled by the licensee. The licensee had shted previously that ins were evaluated by the corporate architect / engineer. It was found that site compliance distributed ins to site groups for review. Catawba compliance had files on ins and site group responses which varied from little input to complete evaluations. . Recently issued ins, 86-72 and 86-77 (issued in August), were available with their evaluations. Duke auditors sampled ins during their audits. The depth of the evaluation of ins reviewed by site and corporate audit personnel varied from checking compliance files to reviewing evalua-tion The Duke audit group had not received IN 86-72 and 86-77. IN 86-77 dealt with Computer Program Error Report Handling that addressed computer program error in safety related applications. Without knowledge of IN 86-77 Duke auditors had investigated and were continuing to investigate Duke computer software program benchmarking (accuracy verification) that was being identified in audits. Computer program problems are still being investi-gated by Duke auditor One of the computer systems being evaluated by Duke auditors is the Operator Aid Computer (0AC). The OAC provided plant operations personnel with information on plant status, but this information was not to serve any safety related function. Duke Power Company's response to IE Bulletin 85-01 (letter from Mr. Tucker of Duke to Dr. Grace of the NRC dated February 25, 1986) indicated that modifications surrounding the auxiliary feedwater pumps were underwa Temperature monitoring of the piping near the pumps was stated to be carried out manually until modifications were~ complete which would allow monitoring by the OAC in the control room; this implied that the OAC would take on a safety related function. The inspector determined what means of piping temperature monitoring took place when the OAC was out-of-service. Although manual monitoring was not directly, procedurally addressed in the OAC out-of-service procedure which delineated recovery actions for certain automatic functions Lonitored by the OAC, the piping temperatures were manually monitored on log sheets (at the site, the sheets are called rounds). The log sheets require manual piping temperature monitoring when the OAC was not in operation. The log sheets are loosely

described (each particular log sheet and the measured parameter were not in the instruction) proced' ally and the sheets were issued by the procedure writers in the operations group in lieu of document control. The inspector reviewed completed log sheets for the past several months up to the present outage and found feedwater piping temperature entries even when the OAC was in operation (conservative). During this inspection, which was an outage situation for both units, no feedwater piping log sheets could be found in the control room and one shift supervisor was unaware that the subject log sheet had been separated from the main body of log. sheets (a recent change).

All three dayshift operations personnel interviewed who routinely used the logs for recording the measurements were-aware of the change. Duke auditors are following up on computer related findings per audit report PS-86-1. The inspector did not followup on any other 0AC functions aside from feedwater temperatur Audit Report NP 86-3(CN) reviewed the Duke position on IE IN 85-71, Contain-ment Integrated Leak Rate Testing. The report stated the position taken by corporate personnel that differed from the IN position and the report made no comment on the position. Region II issued violation 50-369/86-16 and 50-370/86-16 regarding the leak rate testing and this violation is still under contentio A McGuire NRC Inspection Repert 50-369/85-31 and 50-370/85-33 contained an inspector followup item (IFI) on the corporate Prohibited Items List. The intent of the list was to prevent the procurement and use of defective components. The IFI was based on Duke Audit Report NP-84-20(MC). Due to the generic implications of the list, the inspector checked to see that the concern was identified to Catawba personne The problems with the list were identified in a Catawba audit report as a comment and, more impor-

,

tantly, in a letter to the site (letter from G. W. Hallman, Manager of Nuclear Maintenance to all Duke sites maintenance superintendents dated September 12,1986). The letter indicated that a change to Nuclear Mainten-ance Administrative Manual was forthcoming that would require additional

reviews against the prohibited item list. The acceptability of the proposed change is pending closure of the IFI and Duke audit report ite Startup audit reports were inspected separatel The findings regarding

Duke auditors did a vertical review of activities at the site and this I review program is supplemented by the surveillance program operated by site QA personnel.- ' As indicated by the Duke audits and this report, Duke auditors do observe some work activities at the site and the licensee did *

_

state that this evolution would be expanded. QA surveillance monitored day to day work activities on a much more comprehensive scale. This surveill-ance program was audited by the corporate audit group. .The surveillance program is not required by regulation. The deficient conditions discovered .,

by the program are subject to regulatio Criterion XVI of reference (a) states as follows:

,

Measures shall be ' established to assure that conditions adverse to quality, . such as failures, malfunctions,. deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. In the case of significant conditions adverse to quality, the measures sha'l assure .that the cause of the condition is determined and corrective action taken to preclude .

repetition. The identification of the significant condition adverse to quality, - the cause of the condition, and the corrective action take '

.shall be documented and reported to appropriate-levels of managemen The key word in the. discussion above is "significant." The word implies a threshold level on findings that. require identification of root cause of a deficiency, method to preclude reoccurrence, and reporting to managemen P The -licensee has initiated a new system for reporting significant deficient  ;

or potentially deficient conditions which was called the Problem Investiga- i tion Report (PIR) system. . Site Directive 2.8.1 listed the determining criteria for initiating a PIR. This criteria provided a threshold in terms of significance of a finding for being entered into the system. The criteria was a positive step in reducing the grey area that is associated -

with the term "significant" in the above regulatio There are three categories of findings included in a surveillance repor The nonconforming item was a deficient condition having significanc Unless a nonconforming item was identified by a surveillance report, no PIR was generally issued. Other items that were reported by a surveillance were called uncorrected (UCC) or corrected conditions . The UCC may or may not be deficient conditions, but supposedly below the threshold level of signifi-canc The UCC were tracked (and uncorrected items corrected) by the QA Surveillance group but the substance of the UCC were not directly reported to management nor were the findings trende The following surveillance reports were reviewed by the inspector:

The UCC and the inspector's comments are as follows:

Uncorrected condition 2 acoressed problems with inspecting fasteners on pipe clamps and snubber pipe attachments. Section 10.0 of Procedure MP/0/A/7650/85 was explicit in requiring that insulation was to be removed to inspect the fasteners. Trades personnel did not remove insulation on the backside of the pipe clamps. A Corrective Action Request (outside of the PIR program) was written by QA. The corrective action consisted of the particular crews being cautioned, the work being reperformed and reverified by the trades, and a note was written on back of the work request involved indicating that the deficiency had occurred and the work crews had been cautione In this case, the error was not undetected due to the presence of the QA inspector observing part of the work. Management above the foreman level was not directly informed of the deficiency. The corrective action may result in no reoccurrence due to the explicit nature of the work instructio Corrected condition - addressed problems with a work request that had not been signed pria to commencing work. Trades personnel involved with the above visual inspection of the snubber fastener (and insula-tion removal) did not obtain a Shift Supervisor signature prior to l

wor The Shif t Supervisor had been telephoned as stated by the

licensee prior to work beginning. The QA surveil'ance personnel had

'

the trades personnel have the work request marked "no" in the applic-able signature block by the t Ms foreman. The inspector reviewed the applicable procedure for fili j out the work request, MMP 1.0, Work Request Preparation. The procedure was unclear to the inspector as to who signed the " clearance for work to begin" block. The root cause for the problem may not have been addressed in the surveillance report.

Per discussion with site planning, a change to MMP 1.0 was probably in

Corrective action outside of or below the threshold of PIR system could

' receive less evaluation and management attention than is warranted. The five tests of 10 CFR part 2, Appendix C,Section V.A., would be applicable in this cas Pending review of the long term results of the above surveillance findings and review of ether corrective actions for surveill-

-ance reports this issue is identified as Inspector Followup Item 50-413/86-45-05 and 50-414/86-48-02, Surveillance Findings Corrective Actio .
