| Title | Licensee-Identified Violation |
| Description | Noncompliance with Pressure and Temperature Limits Report During Vacuum Fill Technical Specification 3.4.3 RCS Pressure and Temperature (P/T) Limits, limitin
condition for operation requires that, RCS pressure, RCS temperature, and RCS heatu and cooldown rates shall be maintained within the limits specified in the PTLR. If th limiting condition for operation cannot be met, Required Action C.1 requires, in part, tha the licensee immediately initiate action to restore parameters to within limits. Contrary t the above, from 1996 until April 8, 2014, the licensee failed to immediately initiate actio to restore parameters to within limits of the pressure and temperature limits report whe operating outside the limits. Specifically, the licensee failed to maintain the parameters within the limits of the pressure and temperature limits report during a reactor coolant system vacuum evolution. The finding was more than minor because it was associate with the human performance attribute of the Barrier Integrity Cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that the reactor coolant system protect the public from radionuclide released caused by accidents or events. Using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, and Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings, Exhibit 4, Barrier Integrity Screen Questions, the finding was determined to be of very low safety significance (Green) because the finding did not challenge the reactor coolant system barrier. The violation was entered into the licensees corrective action program as Condition Report CR-2014-000960. This is the enforcement aspect of the licensee event report discussed in Section 4OA3.2. |
