4. Review of Inspector Followup Items (Closed) Inspector Followup Item (85-11-03), Updating of Surveillance Test Master Procedur This item concerned the SAP-134, Control of Station Surveillance Test Activities, Revision 2, requirement that General Test Procedure (GTP)-701 Surveillance Test Master, be revised every 92 days as required. During the inspection documented in IE Report No. 60-395/85-11, the inspector determined that surveillance testing requirement changes i necessited by issuance of TS Amendment 34 on November 30, 1984, were not included in GTP-701. Further inspector review of the issue determined that the licensee's QA organization had previously identified this discrepancy during audit, II-4-85-J, conducted February 28, 1985. The commitment date to QA for corrective action on this item was March 28, 1985. GTP-701, Revision 4, dated Mar;h 12, 1985, was issued May 12, 198 The procedure incorporated the missing dat . Operational Safety Verification (71707, 71710)

The inspector observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the report perio The inspector verified the operability of selected emergency systems, reviewed removal and restoration logs, and tagout records, and verified proper return to service of affected components. Tours of the control, auxiliary, intermediate, diesel generation, service water and turbine buildings were conducted to observe plant equipment conditions including potential fire hazards, fluid leaks, and excessive vibrations, and to verify that maintenance requests had been initiated for equipment in need of maintenance. The inspector, by observation and direct interview, verified that the physical security plan was being implemented in accordance with the Station Security plan.

l No violations or deviations were identified in this are . Surveillance Observation (61726)

, During the inspection period, the inspector verified by observation / review that selected surveillances of safety-related systems or components was

'

conducted in accordance with adequate procedures, test instrumentation was calibrated, limiting conditions for operation were met, removal and restoration of the affected components were accomplished, test results met requirements and were reviewed by personnel other than the individual '

directing the test, and that any test deficiencies identified during the testing were properly reviewed and resolved by appropriate management personnel.

9. NRC Commitment Tracking

-

On July-11, 1985, the licensee informed the inspector that commitments to revise certain plant procedures by June 30, 1985, made in response to NRC Violations 84-31-01 and 84-37-03, had not been met. Likewise on July 16, s~

1985, the licensee informed the inspector that a commitment to revise a plant procedure by July 1,1985, identified in Special Report 85-003, had not been me > Commitments

Violation 84-31-01, discussed in IE Report 50-395/85-31, identified procedural inadequacies associated with the implementation of the ASME Section XI requirement to verify agreement of actual valve position L with remote indication. In their response to this violation, submitted l- on December 27, 1984, the licensee committed to revising applicable l

Surveillance Test Procedures (STP) by June 30, 1985. Implementation of

.this commitment consisted of revising 20 valve testing STP's to include l a check off for direct observation of valve movement with appropriate i instructions in procedures.

!

I Violation 84-37-03, discussed in IE Report 50-395/85-37, identified a L failure to perform required isolation time (valve stroking) tests for

! three valves prior to entering the Mode in which these valves were l required to be operable. In their response to this violation, dated March 1,1985, the licensee identified a procedural inadequacy as a contributory factor and as part of their corrective action, the

, licensee committed to developing .a new series of Mode dependent

. procedures by June 30, 198 The procedure associated with this

!

'

violation also required revision to incorporate the position verifi-cation requirements discussed in conjunction with violation 84-31-01, discussed abov To satisfy the commitments associated with violations 84-31-01 and 84-37-03, a-total of 23 procedures were required to be revised. By the Jt commitment date, June 30, 1985, 18 of the 23 procedures had been i i l reviewed and approved. The remaining 5 procedures were not reviewed and approved until July 12, 198 ) Licensee Special Report 85-003 (SPR 85-003) dated June 3, 1985, reported to the NRC an invalid failure of Diesel Generator "B" resulting from a blown 0-ring on the air intake header. In SPR 85-003, the licensee committed to revising the preventative maintenance program to add replacement of these 0-rings every four years. The applicable preventative maintenance procedure was to be revised to incorporate this commitment by July 1,1985. The revision to Mechanical Mainte-

,

nance Procedure 180.033 which implements this commitment, was not k reviewed and approved until July 19, 1985.

6 Impact on Plant Safety The impact on continued safe operation of the facility as a result of not having these procedure revisions issued by the commitment dates was minima The ASME Section XI valve position verification requirement, the basis for violation 84-31-01, was performed in response to this violation during the 1984 refueling outage using temporary changes to existing valve stroke procedure This valve position verification is a once per two years requirement, therefore, not due to be performed again until 1986. These temporary procedure changes remained in effect and would have prompted position verification had the need arose following maintenance activities on these valve The procedural changes identified. in response to Violation 84-37-03 were necessary enhancements to. replace a technically adequate, but very p difficult to manage, single procedure with several more manageable Mode

l l 10. Substantial Safety Hazard - 10 CFR Part 21 Reports (36100) I l

l During this reporting period, the inspector conducted an evaluation of

certain aspects of the licensee's program for identification, evaluation and reporting of defects ed non-compliance per the requirements of 10 CFR Part 2 The reference materials utilized during this evaluation were as follows

10 CFR Part 21 NUREG 0302 The primary focus of this evaluation was the licensee's programmatic controls for assuring timely commission notification following the deter-mination that a defect or non compliance existed that could create a substantial safety hazard. This evaluation consisted of a review of the licensee's implementing procedures and selected records associated with Part 21 reports made to the commission since 198 c

. .

In the case of a power reactor licensee, 10 CFR Part 21 requires that appropriate procedures be adopted to provide for evaluating deviations and assuring that a responsible officer is informed if the construction or operation of a facility, or activity or basic component fails to comply with applicable regulations relating to a substantial safety hazard, or contains a defec CFR Part 21 further requires that the responsible officer notify the commission within two days following receipt of this informatio The inspector reviewed the following licensee procedures which implement this requiremen Nuclear Operations Department Management Directives Manual, Rev. 17 Nuclear Licensing Procedure (NL)-111, Processing and Disposition of 10 CFR 21 Items After Issuance of an Operating License, Rev. 4 Technical Services Procedure (TS) 123, Processing and Disposition of Substantial Safety Hazard, Rev. 1 As delineated in these procedures, the determination that a potential substantial safety hazard exists is the responsibility of the licensee's Nuclear Engineering (Technical Services) organization. The final determina-tion with regard to reportability lies with the Vice President, Nuclear Operations (VPN0). With the exception of one area of concern, the inspector determined that these procedural controls appeared adequate to meet the requirements of 10 CFR Part 21. The area of concern deals with the licensee's process of informing the VPN0 of TS's determination that an item has been evaluated as a substantial safety hazard. The licensee's procedure only addresses presenting this information to the VPN0 after it has been developed into a written document ready for signature and transmittal to the

.NR As was identified below during inspector review of submitted 10 CFR Part 21 reports, this methology lends itself to and has resulted in significant delays in notifying the NRC of the existence of a significant safety hazard. (SSH)

The inspector reviewed documentation associated with the seven Significant Safety ' Hazard reports mada by the licensee since 1983. This documentation indicated that in each of the seven cases, the Commission was notified as required by 10 CFR Part 21 within two days of presenting the VPN0 with the evaluation result But, a review of.the time periods following completion of the evaluations by the reviewing engineer until the presentation of material to the VPN0 appear to confirm the inspectors concern. These time periods are as follows:

To implement this requirement,10 CFR Part 21 identifies a two day time frame for notification following the responsible officer obtaining information reasonably indicating a failure to comply or a defect exists. This initial commission notification may be other than written, but a written report must be submitted within five day Except for these identified time frames of two and five days following a responsible officer being informed,10 CFR Part 21 appears silent regarding " timeliness" for evaluating and processing of SSH determinatio Discussions with the licensee, in light of the data presented above, has led to a determination that program enhancements need to be made to improve the

" timeliness" associated with the processing of these SSH items. The licensee has committed to implement program enhancements to expedite processing of SSH determinations. Implementation of these program erhance-ments will be tracked for subsequent review as Inspector Followup Item 85-30-0 . Review of Startup Rate Event (92700)

On July 23-24, 1985, a special team inspection was conducted to determine if inadequacies in the licensee's training program were significant contributors to the February 28, 1985 high startup rate even The inspection consisted of reviewing selected personnel training records, plant
