Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Title 10 CFR Part 50, Appendix B, Criteria V, Procedures, requires, in part, that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances. Contrary to the above, prior to April 15, 2012, the licensee failed to prescribe documented procedures for activities affecting quality of a type appropriate to the circumstances. Specifically, during low power physics testing in Unit 3, one control element assembly (CEA) stopped moving while its associated group was being inserted, concurrent with a boron dilution of the reactor coolant system. Operators stopped the control element assembly movement, but were forced to manually trip the reactor because reactor power increased above the test band limits. The licensees investigation determined that the low power physics testing procedure, 72PY-9RX04, did not effectively communicate or provide contingencies for stabilizing power during additions of positive or negative reactivity when selected CEAs are not available to stabilize power. The licensee implemented corrective actions to revise the procedure to include appropriate contingencies and to determine acceptable power limits requiring a manual reactor trip during low power physics testing. The inspectors concluded that the finding is of very low safety-significance (Green) because it did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition, and has been entered into the licensees corrective action program as CRDR 4173029.
