Decoupling an Assumed Loss of Offsite Power From a Loss-of-Coolant Accident

The U.S. Nuclear Regulatory Commission (NRC) is discontinuing the rulemaking activity, ``Decoupling an Assumed Loss of Offsite Power from a Loss-of-Coolant Accident'' (the LOOP/LOCA rulemaking), and denying the associated petition for rulemaking (PRM), PRM-50-77. The purpose of this action is to inform members of the public of the discontinuation of the rulemaking activity and the denial of the PRM, and to provide a brief discussion of the NRC's decision regarding the rulemaking activity and PRM. The rulemaking activity will no longer be reported in the NRC's portion of the Unified Agenda of Regulatory and Deregulatory Actions (the Unified Agenda).
