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,
