Post-fire operator manual actions (OMAs) are actions performed by plant personnel on plant equipment to recover from a fire. These actions are written in procedures and generally include actions performed outside of the normal control room.
OMAs are necessary to support normal plant operations. Post-fire OMAs are different than normal OMAs since they are often performed in time critical and under stressful circumstances, such as in response to a plant fire.
Post-fire OMAs used in the place of physical protection often require prior NRC review and approval.
Post-fire OMAs are either documented in special procedures that are used following a fire or special fire procedures reference normal or emergency (non-fire) procedures.
Plant personnel are trained on the post-fire OMAs.
Licensees are required to analyze post-fire OMAs to ensure that the post-fire OMAs can adequately protect safe shutdown.
