SUMMARY

OF OPERATING EXPERIENCE The Comanche Peak Steam Electric Station (CPSES) is a dual unit pressurized water reactor power plant, supplied by Westinghouse Electric Corporation. It is located in Somervell County in North Central Texas approximately 65 miles southwest of the Dallas-Fort Worth Metropolitan area. Each generating unit core was originally designed for a warranted power output of 3411 Megawatt thermal (MWt). This output, combined with the reactor coolant pump heat output of 14 MWt, gives a warranted NSSS output of 3425 MWt, which is the license application rating. Both units rated thermal power was subsequently increased to 3458 MWt, which represents a 1.4 percent increase in core output (from 3411 to 3458 MWt). The reactor coolant pump heat output considered in the safety analysis was increased to approximately 16 MWt for both units. All safety systems, including the engineered safety features, are designed for operations at a maximum NSSS output of 3579 MWts and an associated maximum core output of 3565 MWt 1.1 CPSES UNIT I CPSES Unit I 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 I has generated 108,985,123 net Megawatt-hours (MWH) of electricity as of December 31, 2003, with a net unit capacity factor of 80.8% (using MDC). The unit and reactor availability factors were 87.2% and 90.4%, respectively, for the year 2003.

There was no refueling outage for Unit I during 2003.

Figure 1.1-1 provides the generation profile of the average daily net electrical output of Unit 1 for 2003. 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.

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

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 87,055,302 net Megawatt-hours (MWH) of electricity as of December 31, 2003, with a net unit capacity factor of 82.9% (using MDC). The unit and reactor availability factors were 88.0% and 91.2%, respectively, for the year 2003.

On October 4, 2003, the unit began the power ramp down for its seventh refueling outage. The unit entered the refueling outage on the same day.

During the refueling outage, 84 fresh fuel assemblies were loaded for Cycle 8. The refueling outage lasted 25 days and ended on October 29, 2003. Unit 2 reached 100% power on November 6, 2003.

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

  • Reactor Vessel BMI and Alloy 600 Inspections
  • Inspect and replace one RCP cartridge seal
  • Minor Inspection of Main Generator and exciter.
  • Digital Turbine Generator upgrade
  • Fuel Corrosion (Oxide) Measurements to Support the Elevated pH Program Figure 1.2-1 provides the generation profile of the average daily net electrical output of Unit 2 for 2003. 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 I There were no irradiated fuel inspections performed on Unit 1 fuel in 2003.

4.2 CPSES UNIT 2 During refueling outage 2RF07, visual examinations of Unit 2, Cycle 7 fuel assemblies were performed by inspection personnel by viewing the assemblies from the edge of Spent Fuel Pool

  1. 2 as assemblies were off-loaded from the core. Visual underwater camera exams were also performed on selected assemblies as part the oxide measurement campaign performed during the outage in support of the demonstration elevated pH program.

From the inspections discussed above, all fuel assemblies appeared to be in good condition with no anomalies observed. During the underwater camera examinations performed during the oxide measurement campaign, the surface of the rods in the lower duty/burnup assemblies generally appeared to contain less crud than observed during underwater camera inspections performed during previous outages. However, some of the higher duty/burnup assemblies contained "streaks" of crud in the upper portion of the fuel assembly.

Fuel Clad Corrosion (Oxide) Measurements:

Review of 2RF06 Results:

During the previous Unit 2 refueling outage (2RF06), eight fuel assemblies were inspected for crud deposition and cladding corrosion (oxide thickness). The purpose of this exam was to benchmark crud and corrosion performance before implementation of an elevated RCS pH program in Unit 2 beginning in Cycle 7. All assemblies measured were of the Framatome ANP design with optimized zircaloy4 clad. The measured oxide thickness results were generally as expected with some minor crud deposition observed on most fuel assemblies. A few specific locations contained darker, thicker crud.

2RF07 Results:

The purpose of the oxide measurements performed during 2RF07 was to determine if there had been any significant increase in oxide thickness which could have resulted from operation of the demonstration elevated pH program during Cycle 7. Unit 2, Cycle 7 was operated at a reactor coolant pHt of 7.3 with a maximum lithium concentration of 5 ppm. During this oxide measurement campaign, oxide measurements were again performed on Framatome ANP fuel assemblies that were measured during 2RF06 and on four once-burned Westinghouse supplied fuel assemblies containing ZIRLOGm clad. The Westinghouse supplied assemblies were loaded fresh during 2RF06.

Based on the results of the oxide measurements, the continuation of the demonstration elevated pH program for U2C8 operation was approved. The results of the oxide measurements and crud observations and comparisons to previous campaigns and vendor predictions were reviewed with no significant adverse trends observed. There were no other issues identified that precluded an increase in the pH program for U2C8 operation. Therefore, based upon the review of the data, the continuation of the demonstration Unit 2 elevated pH program was approved and implemented at a constant pHt of 7.4 with a maximum lithium concentration of 6 ppm.

A report containing raw oxide measurement data and a summary of the results and conclusions of the oxide measurement campaign during 2RF07 was transmitted to the Nuclear Regulatory Commission on January 25, 2004 (TXU Energy letter TXX-04016).

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 I 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 2003.

During 2003 Unit 2 conducted a refueling outage (see section 1.2). During the outage activities, no individual received radiation exposure exceeding 10% of an allowable dose limit in a single exposure event. Exposure is tabulated in Table 6.0.
