| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50.54(q), states that power reactor licensees shall follow and maintain in effect emergency plans which meet the standards in 10 CFR Part 50.47(b) and Appendix E to Part 50. 10 CFR Part 50.47(b)(4) requires, in part, that the nuclear facility licensee have a standard emergency classification and action level scheme in use, and state and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial off-site response measures. Appendix E, Section IV.C.2 states in part that, nuclear power reactor licensees shall establish and maintain the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indications to plant operators that an emergency action level has been exceeded and shall promptly declare the emergency condition as soon as possible following identification of the appropriate emergency classification level. Contrary to the above, on November 4, Unit 3 control room operators received a fire alarm in the A EDG enclosure at 10:56 AM, but did not declare an Unusual Event for a fire in a safe shutdown area until 11:25 AM. The control room received a report from the EDG enclosure at approximately 10:55 AM that there were visible flames on the exhaust line of the A EDG and they entered Emergency Operating Procedure 3509, Fire Emergency, but the declaration was not made within the required 15 minutes. The control room operators received additional information that there was charring and scorching on the A EDG at 11:33 AM and appropriately upgraded the emergency declaration to an Alert (fire affecting a safe shutdown area and damage to the equipment indicated). The upgraded Alert declaration was made at 11:35 AM, within the required 15 minutes. The inspectors determined that the finding is of very low safety significance (Green) because it was related to the timeliness of an NOUE, in accordance with IMC 0609, Appendix B, "Emergency Preparedness Significance Determination Process, Attachment 1, "Failure to Implement (Actual Event) Significance Logic." Dominion entered the issue into the CAP as CR 1017078. |
