United States Nuclear Regulatory Commission - Protecting People and the Environment

Materials and Plant Protection (Division 5): Regulatory Guides 5.21 - 5.40

This page lists the number, title, publication date, and revisions for each regulatory guide in Division 5, "Materials and Plant Protection," with references to draft guides and related documents (where applicable).

See also Draft Regulatory Guides for Division 5.

See NRC Regulatory Guides for more general information.

Regulatory Guides are reviewed about every 10 years, although a guide may be reviewed more frequently if the staff believes an emerging issue affects the guide. The NRC began these reviews in 2010, and began posting the results of its reviews on this site in 2013. The review dates are hyperlinked to the review memorandum, which provide useful information about the status and any known issues with the associated regulatory guide.
