SUPPLEMENTARY INFORMATION:

[[Page 39732]]

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing for public 
comment a draft regulatory guide in the agency's ``Regulatory Guide'' 
series. This series was developed to describe and make available to the 
public such information as methods that are acceptable to the NRC staff 
for implementing specific parts of the NRC's regulations, techniques 
that the staff uses in evaluating specific problems or postulated 
accidents, and data that the staff needs in its review of applications 
for permits and licenses.
    The draft regulatory guide (DG), entitled ``Physical Models for 
Design and Operation of Hydraulic Structures and Systems for Nuclear 
Power Plants,'' is temporarily identified by its task number, DG-1198, 
which should be mentioned in all related correspondence.
    This guide describes the desired coordination of an applicant with 
the staff of the NRC and the detail and documentation of data and 
studies that an applicant should include in the preliminary safety 
analysis report (PSAR) or final safety analysis report (FSAR) to 
support the use of physical hydraulic model testing for predicting the 
performance of hydraulic structures and systems for nuclear power 
plants. The regulatory position of this guide is applicable only to 
physical models used to predict the action or interaction of surface 
waters with features located outside of containment. The 
recommendations of this guide do not apply to internal plant systems or 
structures.
    Title 10, Section 50.34(a)(3)(ii) of the Code of Federal 
Regulations (10 CFR 50.34(a)(3)(ii)) requires that the PSAR include 
information on the design bases of the facility and the relation of the 
design bases to the principal design criteria. In part, 10 CFR 
50.34(a)(4) requires a preliminary analysis of the adequacy of 
structures, systems, and components provided for the prevention of 
accidents and the mitigation of the consequences of accidents.

II. Further Information

    The NRC staff is soliciting comments on DG-1198. Comments may be 
accompanied by relevant information or supporting data, and should 
mention DG-1198 in the subject line. Comments submitted in writing or 
in electronic form will be made available to the public in their 
entirety through the NRC's Agencywide Documents Access and Management 
System (ADAMS).
    Personal information will not be removed from the comments. 
Comments may be submitted by any of the following methods:
    1. Mail to: Rulemaking, Directives, and Editing Branch, Office of 
Administration, U.S. Nuclear Regulatory Commission, Washington, DC 
20555-0001.
    2. E-mail to: [email protected].
    3. Hand-deliver to: Rulemaking, Directives, and Editing Branch, 
Office of Administration, U.S. Nuclear Regulatory Commission, 11555

p.m. on Federal workdays.
    4. Fax to: Rulemaking, Directives, and Editing Branch, Office of 
Administration, U.S. Nuclear Regulatory Commission at (301) 415-5144.
    Requests for technical information about DG-1198 may be directed to 
John Burke at (301) 415-1529 or e-mail to [email protected].
    Comments would be most helpful if received by September 5, 2008. 
Comments received after that date will be considered if it is practical 
to do so, but the NRC is able to ensure consideration only for comments 
received on or before this date. Although a time limit is given, 
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.
    Electronic copies of DG-1198 are available through the NRC's public 
Web site under Draft Regulatory Guides in the ``Regulatory Guides'' 
collection of the NRC's Electronic Reading Room at http://www.nrc.gov/reading-rm/doc-collections/. Electronic copies are also available in 
ADAMS (http://www.nrc.gov/reading-rm/adams.html), under Accession No. 
ML081080301.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR), which is located at 11555 Rockville 
Pike, Rockville, Maryland. The PDR's mailing address is USNRC PDR, 
Washington, DC 20555-0001. The PDR can also be reached by telephone at 
(301) 415-4737 or (800) 397-4205, by fax at (301) 415-3548, and by e-

    Regulatory guides are not copyrighted, and Commission approval is 
not required to reproduce them.
