| Title | Unanalyzed Condition Due to Identified Non Compliant Fire Protection Manual Operator Actions |
| Event Description | During performance of NFPA-805 Transition Project Task SUP-1, 'Manual Action Compliance,' it was determined there were 5 non-compliant manual operator actions that were being performed to achieve and maintain hot safe shutdown in Fire Area 29, Admin Building Electrical & Piping Room 1. These manual actions were being performed in an Appendix R Section III.G.1/G.2 fire area, however, they do not meet the criteria for allowable manual actions specified in RIS 2006-10, 'Regulatory Expectations with Appendix R Paragraph III.G.2 Operator Manual Actions.'
The discovery of these non-compliant manual actions is being reported as an unanalyzed condition as defined by 10 CFR 50.72(b)(3)(ii). The alternate compensatory measure for Fire Area 29 is to perform the manual action. An extent of condition review has been initiated that will encompass the remainder of the safe shutdown areas in both Prairie Island Nuclear Generating Plant (PINGP) units. The results of the extent of condition will be documented in the site's corrective action program with compensatory measures being established as appropriate. The 60-day licensee event report, submitted to the Commission in accordance with 10 CFR 50.73(a)(2)(ii), will provide the results of the manual action compliance review and follow-up corrective actions. The licensee will notify the NRC Resident Inspector.
During performance of NFPA-805 Transition Project Task SUP-1, 'Manual Action Compliance,' it was determined that non compliant manual operator actions are credited to achieve and maintain hot safe shutdown for a fire. The following actions were identified during the extent of condition reviews conducted subsequent to EN 43404 report. Numbers of Non-compliant Actions and Fire Areas Affected: 2 actions for Fire Area 2, Ventilation Fan Room, Unit 1; 2 actions for Fire Area 10, Train A Event Monitoring Equipment Room; 6 actions for Fire Area 20, Unit 1 4.16 KV Safeguards Switchgear (Bus 16); 2 actions for Fire Area 22, 480V Safeguards Switchgear (Bus 121); 1 action for Fire Area 23, Unit 2, 4.16 KV Normal Switchgear (Bus 23, 24); 2 actions for Fire Area 30, Administration Building Electrical & Piping Room #2; 1 action for Fire Area 33, Battery Room 11; 1 action for Fire Area 34, Battery Room 12; 6 actions for Fire Area 37, Unit 1 480V Normal Switchgear Room; 4 actions for Fire Area 41A, Screenhouse (DDCWP Rooms); 6 actions for Fire Area 41B, Screenhouse Basement; 10 actions for Fire Area 58 and 73, [Auxiliary] Building Ground Floor Unit 1 & 2; 2 actions for Fire Area 59, [Auxiliary] Building Mezzanine Level Unit 1; 1 action for Fire Area 80, 480V Safeguard Switchgear Room (Bus 112); and 4 actions for Fire Area 81, 4.16 KV Safeguard Switchgear Room (Bus 15). These manual actions are credited for safe shutdown in an Appendix R Section III.G.1/G.2 fire area; however, they do not meet the criteria for allowable manual actions specified in RIS 2006-10, 'Regulatory Expectations with Appendix R Paragraph III.G-2 Operator Manual Actions.' The discovery or these non-compliant manual actions is being reported as an unanalyzed condition as defined by 10 CFR 50.72(b)(3)(ii). The manual actions have been determined to be feasible and will be treated as alternate compensatory measures for Fire Areas 2, 10, 20, 22, 23, 30, 33, 34, 37, 41A, 41B, 58, 59, 73, 80, and 81. An extent of condition review is continuing that will encompass the remainder of the safe shutdown areas in both Prairie Island Nuclear Generating Plant (PINGP) Units. The licensee notified the NRC Resident Inspector. Notified R3DO (M. Phillips).
