A self-revealing
NCV of
TS 5.4.1.a, Procedures, was identified for the licensees failure to verify that the total indicated run-out (
TIR) for the Unit 2 B train
containment spray pump was within the limits of procedure 27052-C, Gould 3415 Pump Maintenance Procedure, Ver. 6.0. This violation was entered into the licensees corrective action program as CR 855892. The failure to implement maintenance procedure 27052-C was a performance deficiency. The performance deficiency was more than minor because it was associated with the
SSC and Barrier Performance attribute of the
Barrier Integrity cornerstone and adversely affected the cornerstone objective in that the failure to verify the 2B
CS pump shaft
TIR was within the procedural and vendor recommendation limits affected the
CS system availability and reliability. The finding to be of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of reactor containment, containment isolation system, or heat removal components, and it did not involve a reduction in function of
hydrogen igniters in the reactor containment. No cross-cutting aspect was assigned to this finding because the inspectors determined that the cause of the finding was not indicative of current licensee performance.
