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.
Reviewed dates (the last column in the table) are when the staff completed a periodic review of the associated guide. Regulatory Guides are reviewed about every 5 years, although in some cases a guide will reviewed before the normal 5 year period. 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.
The NRC encourages suggestions from stakeholders regarding any Regulatory Guide or development of new guides at any time. Suggestions received in this manner will be reviewed upon receipt, but will typically be fully evaluated during the next periodic review of the affect guides.
