Review of Plant Operations in Cold Shutdown a.
Backaround On March 28, 1979, Unit 1 was in hot shutdown in preparation for startup following refueling, when a reactor incident occurred at Unit 2.
Due to the uncertainties associated with the Unic 2 event, its impact upon Unit 1 operation, and the reduction of Unit 1 personnel resources to support Unit 2 incident operations, plant management directed that Unit 1 be taken to cold shutdown.
The plant cool down was completed durfng March 29-30, 1979.
The purpose of this inspection was to verify compliance with Technical Specifi-cation requirements for cold shutdown and to determine the ability to naintain Unit 1 in a stable condition based on satisfactory completion of applicable surveillance testing.
