1.0 INTRODUCTION
The Virgil C. Summer Nuclear Station Unit 1 (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, 2023, the station operated at a capacity factor of 88.8% (using maximum dependable capacity) and a unit availability of 87.9%. The reactor was critical for a total of 7713.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, the generator remained on line 7698.4 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 2023 was 7,820,098 MWH.
3.0 OPERATING
SUMMARY
VCSNS operated at 100% power from January 1 until January 4. On January 4 at 13:19 EST, power reduction to 90% was commenced to perform Main Turbine Valve Testing. Reactor power was restored to 100% on January 4 at 20:50 EST. VCSNS operated at 100% power from January 5 until April 5.
On April 5 at 0651 EDT, VCSNS manually tripped the reactor following the automatic trip of Main Feedwater Pump C (TPP0022C), while at reduced power for testing, in preparation for refueling outage 27 (RF27). RF27 commenced following the trip on April 5 and was completed May 19.
Following RF27, VCSNS maintained approximately 40- 42% reactor power from May 19 at 12:28 EDT to May 23 at 14:25 EDT for secondary chemistry holds. During subsequent power ascension, Reactor power ascension was delayed while investigating high vibration on B Main Feedwater Turbine (TPP0022B). Reactor power was restored to 100% on May 28 at 14:13 EDT.
On November 27 at 10:15 EST, power was reduced to 90% to perform Ma in Turbine Valve Testing. Reactor power was restored to 100% on November 27 at 20:03 EST.
The unit remained at 100% power for the remainder of 2023.
