Title | Inadequate Test Procedures for Verification of Steam Dump Arming From Reactor Trip (P-4) Signal and P-4 Contact Verification |
Description | A self-revealing NCV of TS 5.4.1.a. for failure to implement FNP-1-STP- 33.8, Verification of Steam Dump Arming from Reactor Trip (P-4) Signal and P-4 Contact Verification, was identified when licensee personnel took actions not directed by the procedure. During performance of FNP-1-STP- 33.8, licensee personnel changed the established initial conditions by placing the Solid State Protection System (SSPS) into a different operating mode. This finding has been entered into the licensees CAP as CR 2009104718. The failure to follow FNP-1-STP- 33.8 is a performance deficiency. This finding is more than minor because it was associated with the Mitigating Systems cornerstone attribute of Configuration Control and adversely affected a cornerstone objective in that failure to follow the procedure resulted in changing the initial conditions previously established. This finding was determined to be of very low safety significance because the procedure was successfully preformed prior to entering a mode that required the SSPS to be operable. This finding has a cross-cutting aspect of Work Control in the area of Human Performance (H.2(b)) in that the licensee did not keep personnel apprised that the SG LO-LO level reactor trip signal in SSPS would not be blocked using the Normal Method |
