The Nuclear Regulatory Commission has issued revisions to a regulatory guide and its conforming standard review plan chapter. The Regulatory Guide 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.
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,” provides guidance acceptable to the NRC staff on the use of probabilistic risk assessment (PRA) findings and risk insights in support of licensee requests for changes to a nuclear power plant's licensing basis.
Revision 1 of Standard Review Plan Chapter 19, “Use of Probabilistic Risk Assessment in Plant-Specific, Risk-Informed Decisionmaking: General Guidance,” identifies the roles and responsibilities within the NRC that participate in risk-informed reviews of licensees' proposals for changes to the licensing basis of nuclear power plants.
