| Title | Failure to Perform 10 CFR 50.59 Evaluation for Design Change |
| Description | The inspectors identified a noncited violation of 10 CFR 50.59, Changes, Tests, and Experiments, associated with the failure to adequately evaluate a change in order to ensure that it did not require prior NRC approval. Specifically, the licensee revised a residual heat removal pump motor cable sizing calculation to a smaller sized cable without a change evaluation. The licensee entered the issue into the corrective action program as Condition Report 2011-01730. The finding was determined to be more than minor because the licensee failed to perform a 10 CFR 50.59 evaluation when required. Specifically, the NRC relies on licensees to identify and report conditions or events meeting the criteria specified in regulations in order to perform its regulatory function, and when this is not done the regulatory function is impacted, and is therefore more than minor. Violations of 10 CFR 50.59 are considered to impede or impact the regulatory process, so they are dispositioned using the traditional enforcement process. The enforcement manual specifies that the severity level is determined in parallel with the Significance Determination Process (SDP). The inspectors performed a Phase 1 screening in accordance with Manual Chapter 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, and determined that the finding was of very low safety significance (Green) because the finding: (1) was not a design or qualification issue confirmed not to result in a loss of operability or functionality; (2) did not represent an actual loss of safety function of the system or train; (3) did not result in the loss of one or more trains of nontechnical specification equipment; and (4) did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. Therefore, the inspectors categorized the finding as Severity Level IV in accordance with the enforcement manual. The finding was a violation determined to be of very low safety significance, was not repetitive or willful, and was entered into the corrective action program. Therefore, this violation is being treated as a noncited violation consistent with the NRC Enforcement Policy. The inspectors determined the cause of the finding through interviews and document reviews. This finding was determined to have a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program in that the licensee failed to appropriately and thoroughly evaluate all factors associated with the design change. |
