1.0 INTRODUCTION
The Virgil C. Summer Nuclear Station (VCSNS) utilizes a pressurized water reactor rated at 2900 MWT. The maximum dependable capacity is 966 MWe.
The station is located approximately 26 miles northwest of Columbia, South Carolina.
2.0 OPERATIONAL DATA For the reporting period of January 1 through December 31, 2013, the station operated at a capacity factor of 98.9% (using maximum dependable capacity) and a unit availability of 97.0%. The reactor was critical for a total of 8519 hours0.0986 days <br />2.366 hours <br />0.0141 weeks <br />0.00324 months <br />, the generator remained on line 8501.4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and the total gross electrical energy generated for 2013 was 8,694,090 MWH.
3.0 OPERATING
SUMMARY
The Virgil C. Summer Nuclear Station (VCSNS) Unit No.1 operated at 100% power from January 1't through January 3 1 st. On January 3 1 st power was reduced to 99% to support instrument calibration and testing of the Nuclear Steam Supply System (NSSS). Power was restored to 100%
on February 1st.
VCSNS operated at 100% power from February 1 st to February 2 8th. On February 2 8 th power was reduced to approximately 99% to support instrument calibration and testing of the NSSS. Power was restored to 100% on February 2 8th VCSNS operated at 100% power from February 2 8 th to March 2 2 nd. On March 2 2 nd reactor power reduction began in preparation for a maintenance outage to replace the "C" reactor coolant pump mechanical seal assembly.
The main generator was opened on March 2 3rd. The main generator breaker was closed on April 2 nd. Power was restored to 100% on April 7th.
VCSNS operated at 100% power from April 7 th to June 2 8 th. On June 2 8 th power was reduced to approximately 90% to support main turbine control valve testing. Power was restored to 100% on June 2 9 th.
Document Control Desk LTD 292 RC-14-0053 Page 5 of 7 VCSNS operated at 100% power from June 2 9th to September 2 7 th. On September 2 7 th power was reduced to approximately 90% to support main turbine control valve testing. Reactor power was restored to 100% on September 2 8th VCSNS operated at 100% power from September 2 8 th to December 9 th. On December 9 th power was reduced to approximately 99% during the performance of steam generator steam pressure transmitter calibrations.
Reactor power was restored to 100% on December 1 0 th. The plant operated at 100% power for the remainder of 2013.
Power Reduction >20% Exceeding 4 Hours On March 2 3 rd, the plant was taken offline to replace the "C" reactor coolant pump mechanical seal assembly. The main generator breaker was opened on March 2 3rd and the outage lasted through April 2 nd. Reactor power was restored to 100% on April 7. This outage did not result in any single release of radioactivity or single radiation exposure that accounted for more than 10% of the allowable annual values. The total outage duration was 258.59 hours6.828704e-4 days <br />0.0164 hours <br />9.755291e-5 weeks <br />2.24495e-5 months <br />.
4.0 EXPOSURES Attachment I lists the number of station, utility, and other personnel (including contract personnel) receiving exposures greater than 100 mrem/year and their associated man-rem exposure according to work and job function. The exposures reported are estimated doses based on electronic dosimeters.
5.0 FAILED FUEL VCSNS did not have any indications of failed fuel in 2013.
