Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Criterion III of Appendix B to 10 CFR Part 50 requires, in part, that design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program. Contrary to the above, prior to September 13, 2009, the licensee did not verify the adequacy of design basis calculation ECM98-067, Limiting Single Failure Thermal-Hydraulic Analysis of Spent Fuel Pool, through the performance of a design review. As a result, a single failure of the spent fuel pool level switch would have caused a loss of all the spent fuel pool cooling pumps. The inspectors determined that the finding was of very low safety significance because it did not result in a loss of cooling to the spent fuel pool, whereby operators could preclude restoration of cooling prior to pool cooling, did not result from fuel handling errors that caused damage to fuel clad integrity or dropped assembly, and did not result in a loss of spent fuel pool inventory greater than ten percent of the spent fuel pool volume. The licensee entered this issue into their corrective action program as CR-WF3-2009-4908.
