Notice of Issuance of Regulatory Guide

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance and Availability of Regulatory Guide 1.141, 
Revision 1.


Regulatory Commission, Washington, DC 20555-0001, telephone (301) 251-
7483 or e-mail to [email protected].


I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision 
to an existing guide in the agency's ``Regulatory Guide'' series. This 
series was developed to describe and make available to the public 
information such as methods that are acceptable to the NRC staff for 
implementing specific parts of the agency'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.
    Revision 1 of Regulatory Guide 1.141, ``Containment Isolation 
Provisions for Fluid Systems,'' was issued with a temporary 
identification as Draft Regulatory Guide, DG-1213. RG 1.141 describes 
updated methods that the NRC staff considers acceptable for use in 
complying with the Commission's requirements for containment isolation 
of fluid systems. Title 10, of the Code of Federal Regulations, Part 
50, ``Domestic Licensing of Production and Utilization Facilities'', 
Appendix A, ``General Design Criteria for Nuclear Power Plants,'' 
General Design Criteria 54, 55, 56, and 57 establishes that piping 
systems that penetrate the primary reactor containment be provided with 
isolation capabilities that reflect the importance to safety of 
isolating these piping systems.

II. Further Information

    In June 2009, DG-1213 was published with a public comment period of 
60 days from the issuance of the guide. The public comment period 
closed on August 29, 2009. The staff received no public comments. The 
regulatory analysis may be found through the NRC's Agencywide Documents 
Access and Management System (ADAMS) under Accession No. ML101870472.
