Report Details SUMMARY OF
PLANT STATUS
- Unit 1 began this inspection period at 100 percent power.
On January 31, the heater drain receiver tank level control valve (LCV-1SD-106B) failed in an almost fully closed position. This caused a partial loss of feedwater. Operators responded promptly and were able to manually reopen the valve to mitigate the plant transient. An unplanned power reduction to 70 percent power was performed to facilitate repairs. The unit resumed full power operation on February 1.
Unit 2 began this inspection period at 100 percent power. On February 4, operators shut down the unit and began the ninth refueling outage (2R9). Major activities planned include refueling, 100 percent steam generator tube inspections, and various plant modifications.
REACTOR SAFETY
Cornerstone: Initiating Events, Mitigating Systems, Barrier Integrity
1R05 Fire Protection
a. Inspection Scope
The inspectors reviewed the Unit 1 Updated Fire Protection Appendix R Review, Rev.
16 and the Unit 2 Fire Protection Safe Shutdown Report, Addendum 18 and identified the following risk significant areas:
+ Unit 1 Control Room (Fire Area CR-1)
+ Unit 1 Cable Spreading Room (Fire Area CS-1)
+ Unit 1 Primary Auxiliary Building 735' Elevation (Fire Area PA-1E)
+ Unit 2 Control Room (Fire Area CB-3)
+ Unit 2 Normal Switchgear Room (Fire Area SB-4)
The inspectors reviewed the fire protection conditions of the above listed areas in accordance with the criteria delineated in Nuclear Power Division Administrative Procedure (NPDAP) 3.5, Fire Protection, Rev. 15. Control of transient combustibles, material condition of fire protection equipment, and the adequacy of any fire protection impairments and compensatory measures were included in these plant specific reviews.
b. Findings
No findings of significance were identified.
1R13 Maintenance Risk Assessment and Emergent Work Control
a. Inspection Scope
The inspectors reviewed the scheduling and control of maintenance activities in order to evaluate the effect on plant risk. This review was against criteria contained in Administrative Procedure 1/2-AM-1800, Shutdown Safety, Rev. 0; NPDAP 7.12, Non-outage Planning, Scheduling, and Risk Assessment, Rev. 11; NPDAP 8.30, Maintenance Rule Program, Rev. 6; and Conduct of Operations Procedure 1/2OM-48.1.I, Technical Specification Compliance, Rev. 9. The inspectors reviewed the routine planned maintenance, restoration actions, and/or emergent work for the following equipment removed from service:
+ On January 11, 2001, station personnel performed Unit 2 Operating Surveillance Test (OST)-30.13B, Train B Service Water System Full Flow Test, Rev. 12.
This was the first time this test was performed with the reactor in Mode 1 (power operation) and involved planned entry into several technical specification (TS)limiting conditions for operation (LCO). System restoration following the activity included closure of the recirculating spray (RS) heat exchanger discharge header cross connect valve (2SWS-82). This configuration had the potential to make both RS trains inoperable. A reportability evaluation was in progress at the close of the inspection period (Condition Report [CR] 02-0350).
+ On January 3, technicians performed troubleshooting and corrective maintenance for the 2-3 vital bus inverter which had unexpectedly transferred to its alternate power supply. This degraded material condition placed the plant in a 24-hour TS (LCO), requiring prompt resolution. Technicians identified a failed capacitor in the 25 volt power supply for the inverter and performed repairs promptly.
+ Emergent repair of Unit 2 standby service water pump 2SWE-P21A.
+ Planned maintenance of Unit 2 auxiliary feedwater throttle valve 2FWE-HCV100F
+ Planned maintenance on the 2A-2A2' four kilovolt (kV) bus, during 2R9, required isolation of the Unit 1 emergency diesel generator cross-tie power connection from Unit 2. This reduced the number of available 4kV power supplies to the minimum required by TS. This maintenance was originally scheduled coincident with core off-load. This was the highest risk plant configuration planned during the Unit 2 refueling outage. Risk analysts and plant management reevaluated the schedule and established controls to ensure the 4kV cross-tie was available during the entire core off-load activity. This coordination of activities reduced plant risk during shut down.
b. Findings
No findings of significance were identified.
1R14 Personnel Performance During Nonroutine Plant Evolutions
a. Inspection Scope
The inspectors reviewed human performance during the following Nonroutine plant evolution, to verify procedures were properly implemented and to determine whether personnel performance caused unnecessary plant risk or challenges to reactor safety.
+ On January 31, the Unit 1 heater drain receiver tank discharge valve (LCV-1SD-106B) failed at an almost fully closed position. This valve normally modulates at an almost fully open position to provide 30 percent of total feedwater flow to the steam generators (SG). In response to the valve closure, SG levels decreased below the program band and feedwater pump suction pressure decreased to near the feedwater pump trip set point. Operators successfully responded to this partial loss of feedwater from 100 percent power. Manual control of LCV-1SD-106D was restored and reactor power was reduced in a controlled manner to support permanent repairs. Operator actions included response to numerous plant alarms using the following procedures:
- 1OM-23B.4.AAB, Heater Drain Receiver Level Hi-Lo, Rev. 9
- 1OM-24.4.AAM, Steam Generator Feed Pump Suction Pressure Low, Rev. 1
- 1OM-22.4.AAE, Condensate Pump Discharge Pressure Low, Rev. 2
b. Findings
No findings of significance were identified.
1R15 Operability Evaluations
a. Inspection Scope
The inspectors reviewed operability evaluations in order to determine that proper operability justifications were performed for the following items. In addition, where a component was determined to be inoperable, the inspectors verified the TS LCO implications were properly addressed.
+ During 2OST-30.13B, service water (SW) flow to the B high head safety injection (HHSI) pump lube oil cooler (20.0 gallons per minute), was below the minimum value specified in operator logs. Basis for continued operation (BCO)2-02-001, 2CHS-E25B SWS Low Flow, Rev. 0, was written to evaluate current and past B HHSI pump operability with the degraded SW flow. The BCO concluded that the pump remained operable, and the BCO remains in effect until March 15, 2002 (CR 02-0289).
+ During 2OST-30.13B, SW flow to the B train of RS (B and D RS heat exchangers) was less than the TS required 11,000 gallons per minute. Station personnel found that corrosion scale from within the RS piping had come loose during the full flow test and partially fouled the B RS heat exchanger (2RSS*E21B). Causal assessment of the heat exchanger fouling continued at the close of this inspection period. Engineers determined that the peak SW temperature (80 degrees F) since the last time 2OST-30.13B was successfully performed, was less than the design SW temperature limit (89 degrees F).
Engineers concluded that due in large part to this temperature margin, the B RS train remained operable (CRs 02-0277 and 02-0354).
+ On October 31, 2001, Unit 2 steam generator lo-lo level reactor trip comparator 2FWS*LSK486A was found out of tolerance and not meeting its TS acceptance criteria during the performance of surveillance 2MSP-24.06-I, Loop 2 Narrow Range S/G Water Level Channel III Test, Rev. The inspectors reviewed the operability evaluation for the comparator and the reportability requirements in accordance with 10 Code of Federal Regulations (CFR) 50.72 and 10 CFR 50.73.
b. Findings
No findings of significance were identified.
1R19 Post-Maintenance Testing
a. Inspection Scope
The inspectors reviewed and/or observed several post-maintenance tests (PMTs) to ensure: 1) the PMT was appropriate for the scope of the maintenance work completed; 2) the acceptance criteria were clear and demonstrated operability of the component; and 3) the PMT was performed in accordance with procedures. The following PMTs were observed:
- 2OST-30.13B performed following corrective maintenance to clean corrosion debris from the Unit 2 B RS heat exchanger.
- 2OST-30.1A, Standby Service Water Pump (2SWE-P21A) Test, Rev. 15 and 2OM-30.4.I, Standby Service Water System Shutdown, Rev. 4 performed following corrective maintenance to replace a cracked shaft and resolve degraded seal water flow on the A standby service water pump.
b. Findings
No findings of significance were identified.
1R20 Refueling and Outage Activities
a. Inspection Scope
The Unit 2, ninth refueling outage began on February 4, 2001. The inspectors observed selected reactor shutdown, refueling, and outage maintenance activities to determine whether shutdown safety functions (e.g. reactor decay heat removal, reactivity control, electrical power availability, reactor coolant inventory, spent fuel cooling, and containment integrity) were properly maintained as required by technical specifications, license conditions, and Administrative Procedure 1/2-AM-1800, Shutdown Safety, Rev.
0. Specific performance attributes evaluated, included configuration management, communications, instrumentation accuracy, and identification and resolution of problems. The inspectors closely evaluated configuration and inventory control during periods of reduced reactor coolant system inventory due to the associated increase in shutdown risk. Specific activities evaluated included:
+ 2R9 Pre-Outage Shutdown Safety Review, Rev. 0
+ 2OM-6.4.I, Draining the Reactor Coolant System for Refueling, Rev. 16
+ 2OM-51.4.M, Station Shutdown-Mode 5 Activities, Rev. 1
+ 2OST-36.3, Emergency Diesel Generator [2EGS*EG2-1] Automatic Test, Rev. 16
+ 2OST-36.4, Emergency Diesel Generator [2EGS*EG2-2] Automatic Test, Rev. 16 Additionally, the inspectors reviewed the stations commitments to NRC Generic Letter 88-17, Loss of Decay Heat Removal. The inspectors observed the 2R9 reactor coolant system (RCS) draindown and verified that the reduced RCS inventory level as defined in Generic Letter 88-17 was not reached.
b. Findings
No findings of significance were identified.
1R22 Surveillance Testing
a. Inspection Scope
