Regulatory Guide; Issuance, Availability

The Nuclear Regulatory Commission has issued a new guide in its Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the Commission's regulations, techniques used by the staff in evaluating specific problems or postulated accidents, and data needed by the staff in its review of applications for permits and licenses.

Regulatory Guide 1.183, “Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors,” provides guidance to licensees on voluntarily replacing the traditional source term used in design basis accident analyses with alternative source terms. These alternative source terms allow interested licensees to pursue cost-beneficial licensing actions to reduce unnecessary regulatory burden without compromising the margin of safety of the nuclear power facility.

Comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time. Written comments may be submitted to the Rules and Directives Branch, Division of Administrative Services, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555.

Regulatory guides are available for inspection or downloading at the NRC's web site at < WWW.NRC.GOV > under Regulatory Guides and in NRC's Electronic Reading Room (ADAMS System) at the same site; Regulatory Guide 1.183 is under Accession Number ML003716792.
