The following report is made pursuant to 1 … The following report is made pursuant to 10 CFR 50.73(a)(2)(iv)(A) due to an unintended initiation signal that occurred on January 31, 2017 with James A. FitzPatrick Nuclear Power Plant (JAF) in Mode 5 at zero (0) percent power.</br>On January 31, 2017 at 1425 (EST) the control room received multiple annunciations associated with the following Systems / Trains: </br>Primary Containment Isolation System (PCIS) / Trains A and B</br>Residual Heat Removal System (RHR) / Trains A and B</br>Core Spray (CS) / Trains A and B</br>Reactor Core Isolation Cooling (RCIC)</br>All four (4) Emergency Diesel Generators (EDG) auto-started with their associated Emergency Service Water pumps operating. RHR and CS both received initiation signals but were defeated per procedure. The HPCI (High Pressure Coolant Injection) auxiliary oil pump was taken to Pull-to-Lock per procedure, and the RCIC steam isolation valve cycled until the breaker was opened to close the valve.</br>An evaluation concluded that the (Emergency Core Cooling System - ECCS) initiation signals were caused by the opening of a portable job box that was stored near sensitive equipment. Upon opening the job box, the lid bumped a reference leg resulting in the initiation signals. All initiation signals were reset and systems restored to normal shutdown lineups.</br>The licensee notified the NRC Resident Inspector.</br>* * * UPDATE ON 3/30/17 AT 0840 EDT FROM DUSTIN SCURLOCK TO DONG PARK * * *</br>To the original report, the licensee added, "This condition recurred at 1624 (EDT on 1/31/17).</br>The licensee notified the NRC Resident Inspector.
