When the electrical grid fails due to adverse weather or mechanical failure all too often emergency notification systems around nuclear power stations simultaneously lose all power. Electrical grid failure is potentially an initiating event for a nuclear accident and most probably the opening of an attack by terrorists on a nuke. On NIRS in coalition with 16 organizations and several county governments petitioned the NRC to take emergency enforcement action to require nuclear power station operators to provide emergency backup power sources, preferably through photovoltaic panels, for emergency notification siren systems nationwide.
