| Title | Failure to Follow Procedure Results in Loss of Decay Heat Removal to the Spent Fuel Pool |
| Description | The inspectors reviewed a self-revealing noncited violation of Technical Specifications 5.4.1(a), involving a loss of decay heat removal in the spent fuel pool due to station operators failing to follow the fuel pool cooling and cleanup system operating instruction. The licensee entered this issue into the corrective action program as Condition Report CR-GGN-2010-02172
This finding is more than minor because it is associated with the human performance attribute of the Barrier Integrity Cornerstone and adversely affects the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Using the Manual Chapter 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, the inspectors determined that the finding has a very low safety significance because it only represented a loss of spent fuel pool cooling that would not preclude restoration of cooling to the spent fuel pool prior to pool boiling. The cause of this finding has a crosscutting aspect in the area of human performance associated with work practices, because licensee personnel failed to use adequate self- and peer-checking techniques to remove the filter/demineralizer from service. |
