| Title | Inadequate Procedure for Performing an Acceptable Technical Specification Required Channel Check |
| Description | The inspectors identified a finding of very low safety significance and associated NCV of Technical Specification (TS) 5.4.1.a., Procedures, was identified for the licensees failure to establish and maintain a correct surveillance inspection procedure for redundant reactivity control system (RRCS) channel checks. The licensee entered the issue into the corrective action program as Condition Report 201417635 and took immediate actions for a missed surveillance in accordance with TS. The inspectors determined that the failure to establish and maintain a correct surveillance procedure required by TS 5.4.1.a. was a performance deficiency and resulted in the licensees failure to perform a channel check that meets the TS definition of a channel check. The performance deficiency was determined to be more than minor, and thus a finding, because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the channel check surveillance procedure did not compare the channel indication and status to other indications or status derived from available independent instrument channels measuring the same parameter. The inspectors determined that the finding was of very low safety significance because the finding (1) did not affect a reactor protection system trip signal and the function of other redundant trips or diverse methods of reactor shutdown, (2) did not involve control manipulations that unintentionally added positive reactivity, and (3) did not result in a mismanagement of reactivity by operators. No cross-cutting aspect is assigned as this performance deficiency first occurred in 1986 and is not indicative of current licensee performance. |
