A Green, self-revealing,
NCV of
TS 6.8.1 was identified for the licensees failure to adequately implement a maintenance procedure during a monthly flow channel check for the 2C
Auxiliary Feedwater (
AFW) pump. Specifically, the licensee failed to implement as-written surveillance maintenance procedure 2-SMI-09.05C, 2C
Auxiliary Feedwater Pump Flow Channel Check, when performing the channel checks for both 2C
AFW pump flow transmitters. The licensees failure to follow surveillance maintenance procedure 2-SMI-09.05C, was a
PD. Upon discovery, the flow transmitters were declared
inoperable and subsequently, the condition was promptly restored to normal. The
PD was more than minor because it was associated with the Human Performance attribute of the
Mitigating Systems cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to
initiating events to prevent undesirable consequences. The
PD adversely affected the licensees ability to monitor 2C
AFW flow during a design basis accident. The inspectors determined that the finding was not greater than Green because it did not represent a deficiency affecting the design or qualification of a mitigating system; it did not represent a loss of system and/or function; it did not represent an actual loss of function for at least a single train for more than its TS allowed outage time; and it did not represent an actual loss of function of one or more non-TS trains of equipment designated as high safety-significant in accordance with the licensees
maintenance rule program. The finding involved the cross-cutting area of human performance, with an aspect of avoiding complacency (H.12), in that, the licensee failed to ensure that personnel effectively used human performance tools during the
AFW pump flow channel check to ensure procedure steps were completed as required.
