This four and eight hour notification is b … This four and eight hour notification is being made to report that at 0541 (EDT) on 7/28/16, Salem Unit 1 initiated a shutdown to comply with Technical Specifications due to the inoperability of both source range nuclear instruments. During a reactor startup, with Unit 1 in Mode 2, both source range instruments were reading approximately one decade lower than expected compared to intermediate range and Gamma-Metric instruments and due to the proximity to the estimated critical condition. The condition could also have prevented the fulfilment of the source range instruments safety function to trip the reactor when required.</br>Salem Unit 1 is currently stable in Mode 3. Reactor Coolant system pressure is 2235 psig and reactor coolant system temperature is 547 F with decay heat removal via the main steam dump and auxiliary feedwater systems. Unit 1 has one active shutdown tech spec action statement in effect due to the inoperability of the containment radiation monitor 1R11A. The inoperability of this radiation monitor had no effect on the event. All control rods were manually inserted to place Unit 1 in Hot Standby (Mode 3). No ECCS (emergency core cooling system) or ESF (emergency safety features) systems were required to function during this event.</br>No major secondary equipment was tagged for maintenance prior to this event. No personnel were injured during this event.</br>The reactor was manually shut down and a shutdown margin calculation verified sufficient margin.</br>The licensee notified the NRC Resident Inspector and the local township.</br>* * * RETRACTION FROM MATT MOG TO VINCE KLCO ON 9/26/16 AT 1519 EDT * * * </br>The purpose of this notification is to retract event report number 52129 made on 7/28/2016 at 0925 (EDT). Previously PSEG reported that Salem Unit 1 initiated a shutdown to comply with Technical Specifications (TS) due to the inoperability of both source range nuclear instruments.
