SUBJECT:
NRC INTEGRATED INSPECTION REPORT 50-400/99-05
Dear Mr. Scarola:
On August 28, 1999, the NRC completed an inspection at your Shearon Harris facility. The enclosed report presents the results of that inspection. The results of the inspection were discussed with you and other members of your staff on September 2, 1999.
The inspection was an examination of activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license. Within these areas, the inspection consisted of a selective examination of procedures and representative records, observations of activities, and interviews with personnel. Specifically the inspection covered periodic resident inspections and a scheduled public radiation safety inspection.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be placed in the NRC Public Document Room (PDR).
Sincerely, (Original signed by Brian R. Bonser)

SUMMARY
OF FINDINGS Shearon Harris Nuclear Power Plant, Unit 1 NRC Inspection Report 50-400/99-05 The report covers a six-week period of resident inspection. In addition, it includes the results of announced inspections by a regional senior radiation specialist.
Performance Indicators Verification The initiating events cornerstone performance indicators were reviewed and verified. These included Unplanned Scrams Per 7,000 Critical Hours, Scrams With A Loss Of Normal Heat Removal, and Unplanned Power Changes Per 7,000 Critical Hours. Two years of data was reviewed. No findings were identified.
No findings were identified during this inspection period.
Report Details The unit was at essentially 100% power for the entire period.
- 1.
REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity 1R03 Emergent Work
- a.
Inspection Scope The inspectors reviewed the emergent items described in the following Work Requests/Job Orders (WRJOs):
WR/JO Title 98-AGUQ1 Replace the leaking gasket(s) for 1CS-E016 (excess letdown heat exchanger) 99-AFYL1 Emergency Service Water Pump main reservoir traveling screen will not rotate due to broken coupling 99-AGDL1 A vacuum pump would not stay running
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R04 Equipment Alignment
- a.
Inspection Scope The inspectors performed a detailed review of the emergency diesel generator (EDG) system. This included a review of the Final Safety Analysis Report, and system descriptions; a review of the status of work orders and condition reports (CR) with the system engineer; and a walkdown of the EDG system.
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R05 Fire Protection
- a.
Inspection Scope The inspectors reviewed the high fire risk areas which included four fire zones that did not screen out using the Fire Induced Vulnerability Evaluation methodology in the Individual Plant Examination for External Events (IPEEE). Two zones contained the control room envelope and the other two contained the two switchgear rooms. The
3 inspectors also discussed the fire drill schedule with the licensee to determine when drills would be conducted in the high fire risk areas.
- b.
Observations and Findings No findings were identified and documented in relation to inspection of the high fire risk areas.
The inspectors observed that no drills were scheduled in the switchgear areas. In discussing this with the licensee, the inspectors learned that no fire drill in these areas had been scheduled in at least the past seven years. The licensee had decided that since full scale fire drills in the switchgear rooms could inadvertently initiate plant events, drills would not be conducted in those areas. The IPEEE indicated that the core damage frequency contribution from the two switchgear rooms was 3.1E-6/year and 4.0E-6/year (highest of any room in the plant). The licensee initiated CR 99-01973 to review the fire brigade training for the switchgear areas and to reassess the decision not to conduct drills there.
1R09 Inservice Testing (IST) of Pumps and Valves
- a.
Inspection Scope The inspectors reviewed the performance of the following IST tests:
Number Rev.
Title OST-1041 5
A Train Heating Ventilation and Air Conditioning (HVAC) Safety Related Essential Service Chilled Water (ESCW) Temperature Control Valves (TCVs) Inservice Inspection (ISI) Operability Test OST-1085 13 1A-SA Diesel Generator Operability Test Semiannual Interval MST-I0116 11 Hydrogen Monitor Operability Test
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R12 Maintenance Rule Implementation
- a.
Inspection Scope The inspectors reviewed the licensees implementation of the Maintenance Rule (10 CFR 50.65) with respect to the equipment issues described in the following CRs:
CR 99-01450 Emergency Safeguards Sequencer relay 2-30/1161 was found out of tolerance
4 CR 99-01808 Turbine Driven Auxiliary Feedwater Manual/Automatic station failed CR 99-02087-1 A Waste Gas Compressor Breaker tripped
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R13 Maintenance Work Prioritization & Control
- a.
Inspection Scope The inspectors reviewed the licensees assessments of the risk impacts of removing from service the components associated with the Emergent Work items listed in section 1R03.
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R14 Nonroutine Evolutions
- a.
Inspection Scope The inspectors observed the operating crews performance during the following non-routine evolutions:
Placing excess letdown in service and removing normal letdown from service, August 4, 1999, and August 12-13, 1999, and Response to unidentified reactor coolant system leakage greater than Technical Specification limits, August 4, 1999.
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R15 Operability Evaluations
- a.
Inspection Scope The inspectors reviewed the operability evaluations described in the following Engineering Service Requests (ESRs):
ESR No.
Rev.
Title
5 99-00254 0
Operability Determination for Preaction and Multicycle System 99-00323 0
Excess Letdown Heat Exchanger Piping Operability Determination 99-00331 0
Operability Determination for Response Spectrum Analyzer
- b.
Observations and Findings No findings were identified and documented through this inspection.
1R16 Operator Workarounds
- a.
Inspection Scope The inspectors reviewed the operator work-around associated with operating the letdown pressure control valve in manual rather than automatic control. The inspectors reviewed plant conditions to assess whether operator work-around items were being identified in the operator work-around program.
- b.
Observations and Findings The inspectors observed a fire alarm in the EDG building and the licensees investigation of that alarm. The investigation revealed that the alarm was spurious and was caused by the starting of the motor driven fire pump (MDFP). Licensee operations personnel revealed that these spurious alarms occur frequently when the MDFP is started. The inspectors determined that spurious alarms would direct operator attention and fire brigade response from a real fire. As a result, the licensee initiated CR 99-02369 to document this condition and added the work-around to the program. No findings were identified and documented through this inspection.
1R19 Post Maintenance Testing
- a.
Inspection Scope The inspectors reviewed the following post-maintenance tests:
Number Rev.
Title Related maintenance task EPT-33 20 Emergency Safeguards 99-AEZK1, Replace 2 relays Sequencer System Test in A emergency sequencer OST-1085 13 1A-SA Diesel
