SUMMARY

OF OPERATING EXPERIENCE The Comanche Peak Steam Electric Station (CPSES) is a dual unit pressurized water reactor power plant, Unit 1 is licensed at 3411 Megawatt thermal (MWt) and Unit 2 is licensed at 3458 MWt. It is located in Somervell County in North Central Texas approximately 65 miles southwest of the Dallas-Fort Worth Metropolitan area. The nuclear steam supply system was purchased from Westinghouse Electric Corporation and is rated for a 3425 MWt output. On October 16, 2001, Unit 2 implemented Technical Specification Amendment 89 and TRM Rev.

38, increasing the rating of Unit 2 from 3445 MWt to 3458 MWt output.

1.1 CPSES UNIT I CPSES Unit 1 achieved initial criticality on April 3, 1990. Initial power generation occurred on April 24, 1990, and the plant was declared commercial on August 13, 1990. Since being declared commercial, CPSES Unit 1 has generated 91,573,905 net Megawatt-hours (MWH) of electricity as of December 31, 2001, with a net unit capacity factor of 79.8% (using MDC). The unit and reactor availability factors were 86.6% and 90.3%, respectively, for the year 2001.

On March 24, 2001, the unit began the power ramp down for its eight refueling outage. The unit entered the refueling outage on March 24.

During the refueling outage, 92 fresh fuel assemblies were loaded for Cycle 9. The refueling outage lasted 29 days and ended on April 22, 2001. Unit 1 was returned to 100% power on April 28, 2001.

During the refueling outage, the major work scope completed included:

  • Power range detector replacement
  • Replaced flux thimble tube
  • Smart Motor Modification on RCP 1-03
  • Low Pressure Turbine and Casing Replacement.
  • Eddy current inspection of Last Stage Blades for both LP Turbines
  • Refueling machine Modifications for increased reliability Figure 1.1-1 provides the generation profile of the average daily net electrical output of Unit I for 2001. Table 1.1-1 is a compilation of the monthly summaries of the operating data and Table 1.1-2 contains the yearly and total summaries of the operating data.

1.2 CPSES UNIT 2 CPSES Unit 2 achieved initial criticality on March 24, 1993. Initial power generation occurred on April 9, 1993, and the plant was declared commercial on August 3, 1993. Since being declared commercial, CPSES Unit 2 has generated 70,138,093 net Megawatt-hours (MWH) of electricity as of December 31, 2001, with a net unit capacity factor of 82.7% (using MDC). The unit and reactor availability factors were 88.3% and 92.0%, respectively, for the year 2001.

There were no refueling outages for this unit in 2001. During this reporting period there were no failures or challenges to the Power Operated Relief Valves or Safety Valves.

CPSES-200200528 Attachment to TXX-02040 On October 16, 2001, Unit 2 implemented Technical Specification Amendment 89 and TRM Rev. 38, increasing the rating of Unit 2 from 3445 MWt to 3458 MWt output.

Figure 1.2-1 provides the generation profile of the average daily net electrical output of Unit 2 for 2001. Table 1.2-1 is a compilation of the monthly summaries of the operating data and Table 1.2-2 contains the yearly and the total summaries of the operating data.

During this reporting period there were no failures or challenges to the Safety Valves.

2.0 OUTAGES AND REDUCTIONS IN POWER 2.1 CPSES UNIT 1 Table 2.1 describes unit operating experience including unit shutdowns and provides explanations of significant dips in average power levels for CPSES Unit 1.

2.2 CPSES UNIT 2 Table 2.2 describes unit operating experience including unit shutdowns and provides explanations of significant dips in average power levels for CPSES Unit 2.

3.0 EXPOSURE AND MONITORING REPORT The personnel exposure and monitoring report for CPSES is provided in Table 3.0.

4.0 IRRADIATED FUEL INSPECTION RESULTS 4.1 CPSES UNIT 1 The reactor coolant fission product activity levels were carefully monitored throughout Unit 1, Cycle 8. Analysis of the activity levels indicated no leaking fuel throughout the cycle. During refueling outage 1RFO8, visual inspections were performed by inspection personnel from the edge of the spent fuel pool to assess the external condition of the fuel assemblies. Underwater camera inspections of randomly selected fuel assemblies were also performed. During 2001, several Westinghouse fueled plants continued to report fractured fuel assembly top nozzle holddown spring screws. As a result, underwater camera visual inspections of the top nozzle clamps of the only Westinghouse fuel assembly which operated in Cycle 8 was performed in order to observe any indications of fractured holddown spring screw damage. All fuel assemblies inspected appeared to be in good condition with no anomalies observed.

4.2 CPSES UNIT 2 There were no irradiated fuel inspections performed on Unit 2 fuel since Unit 2 did not have a refueling outage in 2001.

4

CPSES-200200528 Attachment to TXX-02040 4.3 CPSES FUEL POOL As a result of reports of potential top nozzle separation in certain Westinghouse fuel assemblies, CPSES performed underwater camera visual inspections of 9 of 26 Westinghouse fuel assemblies at CPSES that were identified as potentially susceptible to this condition. The inspections were performed in the CPSES spent fuel pool area in June 2001, and consisted of underwater camera visual inspections of a sample of the top nozzle-to-guide tube bulge joints in each of the 9 assemblies. Also, a Westinghouse review of CPSES spent fuel pool chemistry had concluded that the chemistry data was considered good and that potentially susceptible fuel could be handled normally. The results of the visual inspections showed no significant indications of guide tube sleeve corrosion, which would lead to top nozzle separation.

5.0 OUTAGE RELATED SINGLE RADIOACTIVITY RELEASE OR RADIATION EXPOSURE TO AN INDIVIDUAL THAT ACCOUNTS FOR MORE THAN 10 PERCENT OF ALLOWABLE ANNUAL VALUES CPSES Units 1 and 2 did not experience any single release of radioactivity greater than 10% of an allowable dose limit during an outage or forced reduction in power of over 20% of designed power level during 2001.

During 2001 CPSES 1 conducted a refueling outage (see section and 1.1). During the outage activities, two individuals received radiation exposure exceeding 10% of an allowable dose limit in a single exposure event. Exposure is tabulated in Table 6.0.
