| Title | Licensee-Identified Violation |
| Description | A licensee-identified finding of very low safety significance (Green) and associated NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, were identified on November 23, 2012, when the licensee identified that a temporary alteration to the plant had been in place for longer than allowed by procedure without a 50.59 review. During troubleshooting under WO 1527623 on April 30, 2012, the licensee changed the operating set point for differential pressure controller 1-5741-8557. The set-point change was part of an activity to improve responsiveness of the reactor building ventilation system to changes in differential pressure. Troubleshooting continued until June 1, 2012, when the active troubleshooting stopped, but the work activity remained active while other work was performed that impacted reactor building ventilation. On November 23, 2012, the licensee identified that the temporary alteration had been in place for more than 90 days with no 50.59 review having been performed as required by Step 4.1.3 of MA-AA-716-004, Control of Troubleshooting. The finding is more than minor because it adversely affected the design control attribute of the Barrier Integrity Cornerstone objective to provide assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Failure to adhere to process controls for design control during plant modifications or alterations could result in a more significant challenge to plant barriers. The inspectors performed an SDP Phase 1 screening for the finding using IMC 0609, Attachment 04, Initial Characterization of Findings, and IMC 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions, and answered the Reactor Containment questions No. Therefore, the finding screened as very low safety significance, or Green. Title 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings requires in part that activities affecting quality be accomplished in accordance with written procedures. MA-AA-716-004 governs troubleshooting activities and states in part in Step 4.1.3, 10 CFR 50.59 review is also required if a temporary alteration to the facility is established in direct support of the troubleshooting, and the temporary alteration will be installed for 90 days or greater while at power. Contrary to the above, the temporary alteration was in place for more than 90 days without a 50.59 review being performed. The licensee entered the issue into the corrective action program as IR 1430938 and performed the required 50.59 review. Additional reviews were performed to provide assurance that all other changes were being tracked and reviewed as required by procedure. |
