Title

Inadequate Control of Foreign Material over the Spent Fuel Pool during Surveillance Testing

Description

A self-revealing noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for the failure of licensee personnel to follow procedures associated with foreign material exclusion controls, which resulted in a failure to positively control a load beam over the spent fuel pool. Specifically, on November 24, 2010, the licensee failed to implement appropriate foreign material exclusion controls for maintaining positive control on a load beam over the spent fuel pool which dropped and caused damage to the fuel assembly storage rack. This performance deficiency was determined to be more than minor, and therefore a finding, because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the load beam could have fallen and damaged fuel assemblies stored in the spent fuel pool. The finding is associated with the Barrier Integrity Cornerstone and affects the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the finding was determined to have very low safety significance because the finding: (1) does not result in loss of cooling to the spent fuel pool, whereby operator or equipment failures could preclude restoration of cooling prior to pool boiling; (2) does not result from fuel handling errors that caused damage to fuel clad integrity or a dropped assembly; and (3) do not result in a loss of spent fuel pool inventory greater than ten percent of spent fuel pool volume. The finding has a crosscutting aspect in the area of human performance, associated with the decision-making component, because the licensee failed use conservative assumptions in decision making when performing the spent fuel pool refueling machine surveillance test over the spent fuel pool H.1(b)
