| Title | Procedure 0-MA-REM-001.0, Extended Station Blackout, Does Not Close Hydrogen Igniter Breakers |
| Description | The licensee modified their Extended Station Blackout procedure to support the additional function and clarified its intent regarding power to the hydrogen igniters. While preparing to discuss restoration of power to the igniters with the inspector, the licensee identified a deficiency with the Extended Station Blackout procedure. Appendix R of this procedure provided guidance on restoring power to the 480V C and A Vent Boards, which energize the igniters; however, it left all the individual load breakers (including the breakers for the hydrogen igniters) in the OPEN position. Guidance for reclosing the hydrogen igniter breaker was omitted when the igniters were addressed in Revision 3 of the procedure. The licensee revised the procedure and generated a problem report to address this issue (PER 144301). This issue is being considered an Unresolved Item pending further inspection and review: URI 05000327, 328/2008003-02, Procedure 0-MA-REM-000-001.0, Extended Station Blackout, Did Not Close Hydrogen Igniter Breakers |
