The inspectors identified a finding of ver … The inspectors identified a finding of very low safety significance and associated NCV of Technical Specification (TS) 3.8.1 for the licensee failing to perform TS Surveillance Requirement (SR) 3.8.1.6, which verifies the fuel oil transfer system operates to transfer fuel oil from storage tank to the day tank. Specifically, the licensee failed to perform Inservice Testing (IST) of the diesel fuel transfer pumps as intended by TS SR 3.8.1.6</br>The inspectors determined that failure to perform IST of the diesel fuel transfer pumps as intended by TS SR 3.8.1.6 was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems attribute of Equipment Performance 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 (i.e., core damage). The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 4a for the Mitigation Systems Cornerstone. All four questions on this table were answered \"no.\" Specifically, the licensee had still performed functionality tests of the pumps at the required frequency, and if the pumps had exhibited lower than expected flow during a demand period, the fuel day tanks had adequate margin to compensate to allow for operator action. Therefore, the issue screened as having very low safety significance. This finding has a cross-cutting aspect in the area of Human Performance, Work Control because the licensee did not appropriately assess the impact of changes to the work scope or activity on the plant and human performance. Specifically, the licensee failed to recognize that deleting the section of STP 3.8.1-11 that pertained to IST testing of the fuel oil transfer pump would delete steps in the procedure that were required by TS SR 3.8.1.6.
