NRC Withdraws Draft Regulatory Guide on ECCS Rulemaking

The NRC has announced the discontinuance and withdrawal of Draft Regulatory Guide (DG) DG-1216, ‘‘Plant-Specific Applicability of Transition Break Size Specified in 10 CFR 50.46a.” DG-1216 provided guidance for a proposed emergency core cooling system (ECCS) rulemaking which would have allowed a voluntary, risk-informed alternative to the existing requirements for evaluating ECCS performance. The proposed ECCS rulemaking was discontinued on April 13, 2016.  Because the rulemaking has been discontinued, the Commission has determined DG-1216 is not needed.  The discontinuance and withdrawal of DG-1216 is effective as of December 8, 2016.
