Guidance Documents and Reports

To explain how containment-related General Design Criteria (GDCs), as well as the relevant parts of the regulation, are applied, it is necessary to discuss the NRC-generated guidance documents and reports that go hand in hand with the implementation of the regulation.

Regulatory Guides (RGs).

Regulatory guides are issued in 10 divisions and are intended to aid licensees in implementing regulations, in general, and GDCs, in particular. The guides most applicable to nuclear reactors are in Division 1, Power Reactors. Division 2 guides address Research and Test Reactors, and Division 4 guides address Environmental and Siting.

I would like to point out that the regulatory guides are the documents that provide the (NRC) staff position on specific subject, and their use is not mandatory. The applicants/licensees can propose another acceptable alternative that would meet the basic GDC requirements.

Each regulatory guide is listed by Division, Title, Date issued, and Revision No. In this discussion, I am only discussing the regulatory guides related to power reactors. There are over 220 regulatory guides in the Division that provide guidance on implementing various design criteria. I will discuss only the containment- and quality assurance-related guides corresponding to the applicable GDC. Request for single copies of draft or active regulatory guides (which may be reproduced) should be made to the U.S. Nuclear Regulatory Commission, Washington, DC 20555, Attention: Reproduction and Distribution Services Section, or by fax to (301) 415-2289; or by email to This email address is being protected from spam bots, you need Javascript enabled to view it
