Review of Effectiveness of Remediation of Problem Evaluation Reports at WBN U2

As a result of issues discussed during meetings at Watts Bar Nuclear Plant (WBN), an audit was initiated to (1) assess the process for remediating Problem Evaluation Reports (PER) for the WBN Unit 2 project, and (2) determine the effectiveness of remediation stemming from the PER process.We identified improvements needed in the effectiveness and efficiency of the PER process. Specifically, we determined the process could be improved to assure Corrective Action Plans (CAP) were closed out timely by tracking Corrective Action Plans (CAP) that were not approved within 30 calendar days of Project Review Committee (PRC) review. Prior to the issuance of our report, WBN U2 issued a PER to address all CAP timeliness issues from a project-wide standpoint. We also identified an opportunity to improve the trending of PERs and recommended the WBN U2 Quality Assurance Manager expand the trending analysis guidelines to include categorizing of PERs by level of importance and analyzing PER trends according to importance as well as quantity.
