NUCLEAR REGULATORY COMMISSION


Regulatory Guide and Standard Review Plan Chapter; Issuance, 
Availability

    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.
    Comments and suggestions in connection with items for inclusion in 
guides currently being developed or improvements in all published 
guides are encouraged at any time. Written comments may be submitted to 
the Rules and Directives Branch, Division of Administrative Services, 
Office of Administration, U.S. Nuclear Regulatory Commission,
