-COOPER NUCLEAR-STATION EXECUTIVE SUMMARY SEMIANNUAL PLANT PERFORMANCE REVIEW 93 04 OCTOBER-19, 1993 SALP CYCLE 012

(APRIL 25, 1993 THRU October 22, 1994) OVERVIEW The licensee's overall performance has continued to be poor. Significant weaknesses were noted for. the identification and resolution of problems. -The quality assurance organization has been ineffective in identifying programmatic implementation weaknesse Plant management had not demonstrated the ability to promptly and effectively-react to multiple plant and personnel challenge Organizationa1 changes are in progress to return senior management. quality assurance and licensing to the sit .

Several safety system failures occurred because-of design inadequacies which have identified through its design reviews, personnel errors and degraded plant conditions. +The operatioral phase has continued to show good performance while the shutdown performance indicated increased challenges-to the plant and personne II SUMMARY-0F SIGNIFICANT REGULATORY ISSUES ~

I PLANT OPERATIONS PREVIOUS RATINGS SALP 92: 2 93: 2 OPPR 93-03: (NC) SPPR 93-04: (NC)

STRENGTHS: Good operator awareness of equipment available to mitigate events while the plant was shutdown for the refueling outag WEAKNESSES: Operators continued to demonstrate a poor questioning attitud Adverse plant conditions caused by building water in leakage were not promptly addressed. Inaccurate operator aides were not corrected and the actions recuired for a HPCI main control board annunciator were not reviewed and uncerstood. Management response to identified plant and personnel performance issues was slow with the problems continuing before action was take PERFORMANCE ASSESSMENT WITH RECOMMENDATIONS: The licensee's performance in

- this area remained mixed and indicated a high threshold for identifying problems. The day to day evolutions were handled well as was the initial challenges provided by the area flooding. However, the continuing lack of a questioning attitude by the operators and the failure of licensee management to promptly address plant and personnel issues resulted in unnecessary challenges to plant operatio An additional 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> should be added to the 71707-RI to permit 30 RI hours for period remaining.

WEAKNESSES: Management expectations were not well established and maintenance personnel did not demonstrate an overall awareness of the existing management expectations. Inspection of relay racks did not identify the types of concerns expected from management. Maintenance activities performed during the refueling outage appear to have contributed to equipment problems occurring early in the operating cycl PERFORMANCE ASSESSMENT WITH RECOMMENDATIONS: The performance in this area remained consistent with the previous performance assessment. A lack of a questioning attitude continued throughout the maintenance area. Management-2-

SALP 92: 2 93: 2D OPPR 93-03: (-) SPPR 93-04: (-)

STRENGTHS: Good support from the corporate engineering offic WEAKNESSES: Weaknesses were noted with problem resolution. The corrective action overview group was not effective in assessing service water degradatio The GL89-10 was not well implemented and the quality assurance oversight provided was not effective. The licensee's initial response to the MOV and relay rack problems did not demonstrate an awareness for the potential safety significance. Management's expectations for the initial evaluation and resolution of the relay rack issue were not inadequately defined within the engineering department. The status of the BWR level indication modifications were not communicated outside the engineering organization. The task team's coordination of work activities to validate MOV pinion gear assumptions was not well coordinate PERFORMANCE ASSESSMENT WITH RECOMMENDATIONS: Performance in this area has continued to decline. Oversight activities were not effective in identifying GL 89-10 program implementation weaknesse Plant management response to the MOV and relay rack issues were not well defined until after significant NRC involvement occurre The intra and inter communications have remained poo No change to the MIP is recommended. The Operational Safety Team Inspection will address the above weakness and performance concern _ _ .
