By Generic Letter (GL) 83-28 dated July 8, 1983, you were requested to respond to certain generic concerns that developed from the investigation into the failure of scram circuit breakers at the Salem Nuclear Power Plant, Unit 1.

These concerns are categorized into four areas: (Item 1) Post Trip Review; (Item 2) Equipment Classification and Vendor Interface; (Item 3)

Post-Maintenance Testing; and (Item 4) Reactor Trip System Reliability Improvements. Your response to these four areas of GL 83-28 was provided by a letter dated October 25, 1983.

We have completed cur review of your response to Items 3.1.1, 3.1.2, 3.P.1 and 3.2.2 of GL 83-28 relating to Post-Maintenance Testing. The results of our review are provided in the enclosed Safety Evaluation. Based on our review, we find that your Post-Maintenance Testing and RTS Functional Test requirements meet the requirements of GL 83-28 and are, therefore, acceptable. We consider all of the items addressed in Sections 3.1 and 3.2 of GL 83-28 to be resolved.
