| Title | Standby Shutdown Facility (SSF) Diesel Generator (DG) Low Output Voltage |
| Description | TS 5.4.1 required that the licensee implement the commitments contained in UFSAR Chapter 16. These commitments were contained in the licensees SLCs. SLC 16.7-9 required that the SSS shall be functional in Modes 1, 2, and 3. Contrary to the above, from initial plant construction until April 4, 2012, the SSS was non-functional for Units 1 and 2 during Modes 1, 2, and 3 due to inadequate pressurizer heater capacity as a result of low SSF diesel generator output voltage during isochronous operation. This issue was entered into the licensees corrective action program as PIP C-12-3389. The staff reviewed the root cause analysis of the event and concluded that the equipment failure could not have been avoided or detected by the licensees quality assurance program or other related control measures. Therefore, because no performance deficiency was identified and in accordance with Section 3.5 of the Enforcement Policy, the NRC has concluded that the exercise of enforcement discretion is appropriate such that this violation will not be cited. Further, this issue will not be considered in the assessment process or NRCs Action Matrix. |
