| Title | Failure to Correctly Translate Turbine Driven Auxiliary Feedwater Pump Lube Oil subsystem Vent Design Basis into Specifications or Drawings |
| Description | A self-revealing non-cited violation of 10 CFR 50, Appendix B, Criterion III, Design Control, was identified for the failure to correctly translate the design basis of the Unit 2 turbine driven auxiliary feedwater pump (TDAFWP) lube oil subsystem vent into specifications or drawings. The licensee entered this problem into their corrective action program as condition report 378798. The inspectors determined that the licensees failure to correctly translate the Unit 2 TDAFWP lube oil subsystem vent into specifications or drawings as required by Criterion III was a performance deficiency (PD). The inspectors reviewed IMC 0612, Appendix E and determined the PD was more than minor, because it was similar to examples 3b and 3k in that the failure to correctly translate the design into drawings adversely impacted the operation of the system and resulted in reasonable doubt about the operability of the system. The inspectors reviewed IMC 0609 Attachment 4 and determined that the finding was of very low safety significance, or Green, because the finding was a design or qualification deficiency confirmed not to result in loss of operability or functionality. The cause of this finding did not involve a cross-cutting aspect because it is not indicative of current licensee performance. (Section 4OA3.1.2) |
