NUCLEAR REGULATORY COMMISSION


Draft Regulatory Guide; Issuance, Availability

    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.
    The NRC staff is soliciting comments on these proposed revisions. 
In addition, the NRC staff is considering incorporating the impact of 
power uprates on success and failure criteria and the appropriateness 
of the evaluation models into this guidance. The staff is soliciting 
comments on this issue and will incorporate appropriate changes to 
these documents based on comments received.
    This draft guide and draft standard review plan chapter have not 
received complete staff approval and do not represent an official NRC 
staff position.
    Comments may be accompanied by relevant information or supporting 
data. Written comments may be submitted to the Rules and Directives 
Branch, Office of Administration, U.S. Nuclear Regulatory Commission, 
Washington, DC 20555. Copies of comments received may be examined at 
the NRC Public Document Room, 11555 Rockville Pike, Rockville, MD. 
Comments will be most helpful if received by September 17, 2001.
