Notice of Issuance and Withdrawal of Regulatory Guides

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance and Availability of Regulatory Guide (RG) 
1.69, Revision 1 and withdrawal of RG 2.1.

Development Branch, Division of Engineering, Office of Nuclear 
Regulatory Research, U.S. Nuclear Regulatory Commission, Washington, DC

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 RG 1.69, ``Concrete Radiation Shields and Generic 
Shield Testing for Nuclear Power Plants,'' was issued for public 
comment with a temporary identification as Draft Regulatory Guide (DG)-
1187. RG 1.69 describes a method acceptable to the NRC staff for 
complying with the regulations with regard to the design and 
construction of concrete radiation shields in nuclear power plants.
    As stated in Title 10, Section 20.1201, ``Occupational Dose Limits 
for Adults,'' of the Code of Federal Regulations (10 CFR 20.1201), NRC 
licensees shall control the occupational dose to individual adults to 
the limits stated therein. Furthermore, 10 CFR 20.1101(b) provides that 
licensees shall use, to the extent practicable, procedures and 
engineering controls based upon sound radiation principles to achieve 
occupational doses and doses to members of the public that are as low 
as reasonably achievable. General Design Criterion 1, ``Quality 
Standards and Records,'' of Appendix A, ``General Design Criteria for 
Nuclear Power Plants,'' to 10 CFR part 50, ``Domestic Licensing of 
Production and Utilization Facilities,'' requires that structures, 
systems, and components important to safety be designed, fabricated, 
erected, and tested to quality standards commensurate with the 
importance of the safety function to be performed. Appendix B, 
``Quality Assurance Criteria for Nuclear Power Plants and Fuel 
Reprocessing Plants,'' to 10 CFR part 50 requires that measures be 
established to ensure design control and inspection and test controls. 
Appendix B also requires that activities affecting quality be 
accomplished under suitably controlled conditions.
    Also, RG 1.69 encompasses applicable material previously endorsed 
in RG 2.1, ``Shield Test Program for the Evaluation of Installed 
Biological Shielding in Research and Training Reactors.'' Therefore, RG 
2.1 is outdated and it will be withdrawn.

II. Further Information

    In November 2008, DG-1187 was published with a public comment 
period of 60 days from the issuance of the guide. The public comment 
period closed on January 9, 2009. The staff's responses to the public 
comments received are located in NRC's Agencywide Documents Access and 
Management System under Accession No. ML090820436. Electronic copies of 
RG 1.69, Revision 1 are available through the NRC's public Web site 
under ``Regulatory Guides'' at http://www.nrc.gov/reading-rm/doc-collections/.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR) located at Room O-1F21, One White 
Flint North, 11555 Rockville Pike, Rockville, Maryland 20852-2738. 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) 397-4209, 
by fax at (301) 415-3548, and by e-mail to [email protected].
    Regulatory guides are not copyrighted, and NRC approval is not 
required to reproduce them.

    Dated at Rockville, Maryland, this 27th day of May, 2009.
