A self-revealing, non-cited violation of
Technical Specification (TS) 5.4.1a was identified for a failure to adequately establish procedure requirements for protective relay testing which resulted in the inoperability of the \'1H\'
emergency diesel generator (
EDG). The licensee entered this problem into their corrective action program, revised the procedure, and successfully completed the relay testing. The finding was more than minor because it impacted the
mitigating systems cornerstone objective to ensure reliability and capability of systems that respond to
initiating events to prevent undesirable consequences, and the related attribute of procedure quality. The finding was of very low safety significance or Green because it did not result in an actual loss of safety function nor a loss of one train for greater than the allowed Technical Specification outage time. The cause of this finding involved the cross-cutting area of human performance, the related component of resources, and the associated aspect of complete and accurate procedures,
H.2(c), because the failure to establish adequate procedural requirements rendered \'1H\'
EDG inoperable. (Section 1R12
