Start Preamble

The Nuclear Regulatory Commission has issued for public comment a proposed revision of a regulatory guide in its Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques used by the staff in evaluating specific problems or postulated accidents, and data needed by the staff in its review of applications for permits and licenses.

Draft Regulatory Guide DG-1110 is a proposed Revision 1 of Regulatory Guide 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis.” DG-1110 is being developed to provide guidance to licensees on methods acceptable to the NRC staff for assessing the nature and impact of licensing basis changes when the licensee chooses to support, or is requested by the NRC staff to support, such changes with risk information.

A proposed Revision 1 of Chapter 19, “Use of Probabilistic Risk Assessment in Plant-Specific, Risk-Informed Decisionmaking: General Guidance,” of NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” is being issued for public comment as a companion document. Chapter 19 of the Standard Review Plan will be used by the NRC staff for evaluating licensee submittals that use the guidance in Regulatory Guide 1.174 on risk-informed decisionmaking that uses probabilistic risk assessment.

This draft guide and draft standard review plan chapter have not received complete staff approval and do not represent an official NRC staff position.
