If Brattleboro had a town garage where all the trucks were kept and serviced, with all the repair facilities, the fire protection system in the building would have to be designed for the potential hazard of gasoline in trucks (that might leak or spill), of gas bottles (for cutting torches), etc. If a new garage is built and the old one converted to storage of metal furniture, then the fire protection could be reduced.
A nuclear power plant is the same way after the fuel has been removed from the reactor and has “cooled” for at least 60 days. There is a small hazard remaining, but it could only affect the area inside the fence.
Those who are concerned about keeping the operating plant emergency plan should look up the data on fuel-decay heat. They won't believe the Nuclear Regulatory Commission or anyone else.
