SALEM UNIT 1 OPERATIONS

SUMMARY

REPORT APRIL 1983 Unit I was placed in cold shutdown in February following two occurrences of failure of the Reactor Trip Breakers to operate upon receiving an automatic signal from the Solid State Protection System.

The unit has remained shutdown throughout the months of March and April while extensive investigations were conducted by PSE&G, the NRC, and Westinghouse. A number of short and long term corrective actions were identified by these investigations. On April 26, 1983, the NRC Commissioners voted 4 to 1 to authorize the NRC Staff to allow startup of Salem Unit 1. Startup of the Unit is expected shortly, following completion of a requirement for the Office of Nuclear Reactor Regulation.
