NUCLEAR REGULATORY COMMISSION


Notice of Issuance of Regulatory Guide

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance and Availability of Regulatory Guide 6.4, 
Revision 3.

-----------------------------------------------------------------------

FOR FURTHER INFORMATION CONTACT: Mark Orr, Regulatory Guide Development 
Branch, Division of Engineering, Office of Nuclear Regulatory Research, 
U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, 
telephone (301) 415-6373 or e-mail to [email protected].

SUPPLEMENTARY INFORMATION:

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 3 of Regulatory Guide 6.4, ``Verification of Containment 
Properties of Sealed Radioactive Sources,'' was issued with a temporary 
identification as Draft Regulatory Guide DG-6005. This guide directs 
the reader to the type of information acceptable to the NRC staff to 
evaluate and verify the containment properties of sealed radioactive 
sources. The NRC licenses the manufacture and distribution of devices 
containing radioactive byproduct material under Title 10, Part 32, 
``Specific Domestic Licenses to Manufacture or Transfer Certain Items 
Containing Byproduct Material,'' of the Code of Federal Regulations (10 
CFR Part 32). The regulations require, in part, that each application 
for a specific license to distribute devices containing byproduct 
material include information on procedures for prototype tests and the 
results of such tests to demonstrate that the source or device will 
maintain its integrity during the most severe conditions that are 
likely to be encountered under normal or accidental conditions of 
handling, storage, use, and disposal of the sealed radioactive source.
    This regulatory guide endorses the methods and procedures for 
evaluation and verification of the containment properties of sealed 
radioactive sources contained in the current revision of NUREG-1556, 
Volume 3, ``Consolidated Guidance about Materials Licenses: 
Applications for Sealed Source and Device Evaluation and Registration'' 
as a process that has been found acceptable to the NRC staff for 
meeting the regulatory requirements. Since the publication of Revision 
2 of Regulatory Guide 6.4 in August 1980, the NRC has revised the 
requirements for byproduct material containments in 10 CFR Part 32 to 
implement a risk-informed, performance-based approach to regulation. 
NUREG-1556 incorporates this revised approach.

II. Further Information

    In January 2008, DG-6005 was published with a public comment period 
of 60 days from the issuance of the guide. No comments were received 
and the public comment period closed on April 18, 2008. Electronic 
copies of Regulatory Guide 6.4, Revision 3 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), which is 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 18th day of June 2008.

    For the Nuclear Regulatory Commission.
