| Title | Licensee-Identified Violation |
| Description | A violation of 10 CFR 50.55a(g)(4) was identified involving the failure to perform a system pressure test of the reactor vessel flange leak-off line of Units 1 and 2 in accordance with the applicable edition of Section XI of the ASME Code. The identified violation was entered into the corrective action program as Notifications 50524370 and 50524575. The violation was more than minor because it is associated with the Barrier Integrity Cornerstone attribute of systems, structures, components and barrier performance, and adversely affects the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Using Manual Chapter 0609, Attachment A, The Significance Determination Process (SDP) for Findings At-Power, the violation was determined to be of very low safety significance (Green) because the finding did not result in exceeding the RCS leak rate for a small loss-of-coolant accident, and did not affect other systems used to mitigate a loss-of-coolant accident resulting in a total loss of their function |
