| Title | Failure to Provide Accurate Information in Response to Generic Letter 2007-01, Inaccessible or Underground Power Cables Failures that Disable Accident Mitigation Systems or Cause Plant Transients |
| Description | The team identified a noncited violation of 10 CFR 50.9, Completeness and Accuracy of Information, which states in part that information required by statute or by the Commissions regulations, orders, or license conditions to be maintained by the applicant or the licensee shall be complete and accurate in all material respects. Contrary to the above, the licensees May 7, 2007, response to Generic Letter 2007-01, Inaccessible or Underground Power Cable Failures that Disable Accident Mitigation Systems or Cause Plant Transients, did not accurately describe the licensees programs, procedures, or practices for inspection, testing, and monitoring programs to detect the degradation of inaccessible or underground power cables that support emergency diesel generators, offsite power, essential service water, service water, component cooling water, and other systems that are in the scope of 10 CFR 50.65, The Maintenance Rule. The licensee asserted in their response to Generic Letter 2007-01, Question 2, that ANO inspection, testing, and monitoring practices presently include visual cable inspection during routine operations, periodic meggering of cables and connected equipment associated with maintenance activities, and periodic inspection of manholes for dewatering. In fact, there was no evidence that these manholes or cables had ever been periodically or routinely inspected for Unit-1, and none of the cables for either of the units were being routinely inspected as the licensee had asserted. The finding was more than minor because the information was material to the NRCs decision making processes. In accordance with Inspection Manual Chapter 0612, Power Reactor Inspection Reports, the violation was subject to the traditional enforcement process because 10 CFR 50.9 violations impact the NRCs ability to perform its regulatory function. Using the Enforcement Policy, Supplement VII, Miscellaneous Matters, the inspectors characterized the violation as a Severity Level IV violation because it did not meet the Severity Level I, II or III criteria. NRC management reviewed the finding and determined that it was of very low safety significance. Because the violation was of very low safety significance and was entered into the licensees corrective action program as Condition Report CR-ANO-C-2009-1415, this violation is being treated as a noncited violation, consistent with the NRC Enforcement Policy, Section VI.A. The inspectors determined that the finding has a crosscutting aspect in the area of problem identification and resolution in that the licensee failed to implement operating experience directly communicated with a generic letter through changes to station processes, procedures, and equipment P.2(b) |
