| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1, Procedures, requires that procedures be established, implemented, and maintained covering the applicable procedures in Regulatory Guide 1.33. Regulatory Guide 1.33, Appendix A, Section 3 requires procedures for startup, operation, and shutdown of safety-related PWR systems. Contrary to these requirements, on December 16, 2010, engineering personnel determined that an inadequate fill and vent had occurred on a segment of piping for the high pressure safety injection train A discharge piping following maintenance on December 9, 2010. It was subsequently determined that the affected piping did not impact operability of the high pressure safety injection system train A, nor prevent the system from fulfilling its safety function. The licensee took immediate corrective action to determine the scope of the affected piping, complete fill and vent operations, and verify system readiness via ultrasonic testing of high pressure safety injection system piping. Corrective actions to improve system restoration have been implemented. The finding is of very low safety significance and has been entered into the licensees corrective action program as Condition Report Disposition Request 3571997. |
