A self-revealed NCV of Dresden Station Imp … A self-revealed NCV of Dresden Station Improved Technical Specification (TS) 3.6.1.3, Primary Containment Isolation Valves (PCIVs), of very low safety significance was identified for the failure to declare primary containment isolation valve 3-3702 inoperable and take actions in accordance with the requirements of TS 3.6.1.3 required action A. The licensee generated IR 837675 and IR 839009 to address this issue. Corrective actions included: the initiation of a training request to re-enforce with Operations personnel the potential operability issues when light indications are not functioning properly, and the revision of Operations procedures to include guidance to alert users that a failed or flickering indication light associated with a motor operated valve may indicate problems that could affect valve operation, and that valve operability must be verified. The finding was more than minor because it impacted the Barrier Integrity objective to provide reasonable assurance that physical design barriers (i.e., containment) protect the public from radionuclide releases caused by accidents or events. The inspectors completed a Phase 1 significance determination of this issue using IMC 0609, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, The inspectors answered NO to all questions in the Containment Barrier column of Table 4a, therefore the finding screened as Green (i.e., very low safety significance). The inspectors determined that this finding also affected the cross-cutting area of Human Performance, resources aspect (H.2(c)) because the licensee failed to provide complete, accurate and up-to-date proceduresmplete, accurate and up-to-date procedures +
