SUMMARY

The Virgil C. Summer Nuclear Station (VCSNS) Unit No.1 operated at 100% power from January 1st through March 4th. On March 4th power was reduced to 91% to support planned main turbine valve testing. Power was restored to 100% on March 5th.

VCSNS operated at 100% power from March 5th to June 3rd. On June 3rd power was reduced to approximately 89.3% to support planned main turbine valve testing. Reactor power was restored to 100% on June 4th.

VCSNS operated at 100% power from June 4th to July 26th. On July 26th power was reduced to approximately 93% due to failure of C Main Feedwater Booster Pump Motor. The failed motor was replaced. Reactor power was restored to 100% on August 3rd.

VCSNS operated at 100% power from August 3rd to September 9th. On September 9th power was reduced to approximately 90.5% to support planned main turbine valve testing. Power was restored to 100% on September 10th.

VCSNS operated at 100% power from September 10th to November 11th. On November 11th power was reduced to 88.5% due to the malfunction of a heater drain valve level controller on the #1B Feedwater Heater.
