| Title | UFSAR Emergency Bus Voltage Not Updated, Consistent with Current Plant Conditions |
| Description | The inspectors identified a Severity Level lV (SL lV) NCV of Title 10, Code of Federal Regulations (10 CFR) Part 50,71(e) because FitzPatrick personnel did not update the Updated Final Safety Analysis Report (UFSAR) with information consistent with plant conditions. Specifically, FitzPatrick personnel did not remove reference to or correct information in UFSAR Section 8.6.6.c, Emergency Bus Voltages When Operating From the Reserve Source, to reflect current plant conditions with regard to the listed maximum voltage capable of being produced at the emergency bus from the reserve source during a low load condition. This issue was considered within the traditional enforcement process because it had the potential to impede or impact the NRC\'s ability to perform its regulatory functions. FitzPatrick issued condition report (CR) CR-JAF-2011-03023 to address the UFSAR discrepancy. The inspectors concluded that the violation was more than minor because the longstanding and incorrect information in the UFSAR had a potential impact on safety and licensed activities. Excessive voltage on an emergency bus can result in equipment damage, or loss due to the actuation of protective devices such as overcurrent fuses. Similar to Enforcement Policy Section 6.1, example D.3, the inspectors determined the violation was of SL lV because the erroneous information not updated in the UFSAR was not used to make an unacceptable change to the facility nor did it impact a licensing or safety decision by the Nuclear Regulatory Commission (NRC). |
