Technical-Evaluation Report on the Monitoring of Electric Power to the Reactor-Protection System for the Peach Bottom Atomic Power Station Units 2 and 3 (Docket Nos. 50-277, 50-278

摘要

This report documents the technical evaluation of the monitoring of electric power to the reactor protection system (RPS) at the Peach Bottom Atomic Power Station, Units 2 and 3. The evaluation is to determine if the proposed design modification will protect the RPS from abnormal voltage and frequency conditions which could be supplied from the power supplies and will meet certain requirements set forth by the Nuclear Regulatory Commission. The proposed design modifications and Technical Specification changes will provide the required protection for the RPS components from sustained abnormal power. (ERA citation 08:053909)
