II. Further Information

The NRC is issuing for public comment a draft guide in the agency's “Regulatory Guide” series. This series was developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC'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.

The draft regulatory guide, entitled, “Bioassay at Uranium Mills,” is temporarily identified by its task number, DG-8051, which should be mentioned in all related correspondence. DG-8051 is proposed Revision 2 of Regulatory Guide 8.22, previously revised in August 1988.

This guide is being updated to incorporate changes made in 10 CFR Part 20 since Regulatory Guide 8.22, Revision 1 was issued. Comments related to the operation of in-situ recovery mills and associated considerations for bioassay are of particular interest.

Dated at Rockville, Maryland, this 6th day of March, 2012.

For the Nuclear Regulatory Commission.

Chief, Regulatory Guide Development Branch, Division of Engineering, Office of Nuclear Regulatory Research.
