Specify in Abstract below or in LICENSEE EVENT REPORT (LER)
CONTINUATION SHEET circulation and TS 3.8.1.2 for an operable diesel generator. Therefore, the safety functions of the RHR system and the diesel generator may not have been fulfilled with the A ESW train being inoperable due to the inoperability of the A ESW pump coincident with B ESW train being inoperable due to planned maintenance.
CAUSAL FACTORS The root cause evaluation is ongoing. Once the evaluation is complete, a supplemental report will be issued containing the root cause for this event.
SAFETY ANALYSIS
The root cause evaluation is ongoing. Once the evaluation is complete, a supplemental report will be issued containing the safety analysis for this event.
CORRECTIVE ACTIONS
Completed Actions The A ESW pump has been completely rebuilt with new couplings, coupling fasteners, and bearings.
Maintenance and Engineering personnel have applied additional rigor and verifications during the pump reinstallation to minimize any lateral stresses on the pump which could adversely affect the alignment.
Post-maintenance testing has been performed to ensure the maintenance was well executed and pump performance met acceptance criteria.
Planned Actions Planned actions will be determined following completion of the ongoing root cause evaluation.
PREVIOUS EVENTS A review of previous events will be performed and included in the supplement to this LER following completion of the root cause evaluation which will determine the cause of the event.
COMMITMENTS
This report contains no regulatory commitments.
