Content:
fuel is removed from the reactor vessel as the final step before the plant enters decommissioning. However, many of the elements of the operating plant fire protection program continue to be relevant in decommissioning, unless specifically authorized by regulation or an approved fire protection programs, the elements apply during decommissioning until the licensee revises them. The operating plant fire protection program provides the baseline for the decommissioning fire protection program: analysis and description of plant fire hazards, administrative controls, physical protection features, and emergency response capabilities. As will be described in the next section, under 10 CFR 50.48(f) licensees are expected to revise their fire protection programs as appropriate for the various stages of decommissioning. Typically, a licensee will submit requests for licensing actions based on the reduced risk profile after it notifies the NRC that it plans to permanently cease operations. Licensees seek amendments to their licenses, as well as exemptions from certain regulatory requirements that they have determined to have no beneficial contribution to safety or security when the reactor is permanently shut down and defueled. Licensees will also use the 10 CFR 50.59, "Changes, tests, and experiments," process and other specific change processes to make additional changes to the plant that do not require NRC approval. Such changes to the decommissioning design-basis analyses, SSCs, and licensee organizations, processes, and procedures would be reflected in the licensee's defueled technical specifications, post-shutdown decommissioning activities report, and defueled safety analysis report. 1.4 Fire Protection Program for Decommissioning Plants 10 CFR 50.48(f)(2) states, “The licensee shall revise the plan as appropriate throughout the various stages of facility decommissioning.” Under 10 CFR 50.48(f)(3), licensees may make changes to their fire protection programs
