| Title | Failure to Adequately Implement the Requirements of Procedure SOP-ENTRY-DW |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for Energy Personnel Entry into Drywell. Energy Northwests corrective actions for this issue included removing the NRC identified debris from the drywell, informing personnel of the ineffective drywell cleaning, and conducting an assessment to determine more effective methods for cleaning the drywell during future outages. The finding was greater than minor because, if left uncorrected, it could result in the continued accumulation of foreign material in the drywell. The accumulation ercial . Instruction OI-09, Operations Standards and Expectations, Revision 24. As a result, an operator failed to ensure that the turbine lube oil exhauster system was alarm in the control room.

The finding was determined to be of very low risk significance (Green) since the debris did not result in an actual loss of safety function for any system and because the debris was removed by the licensee. A crosscutting aspect in problem identification and resolution, with a corrective action program component was identified in that the licensee failed to ensure that corrective actions were taken to address a previously identified adverse trend P.1(d) |
