01-30928. Draft Regulatory Guide; Issuance, Availability

The Nuclear Regulatory Commission has issued for public comment a draft of 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 NRC'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.

The draft guide, temporarily identified by its task number, DG-1111 (which should be mentioned in all correspondence concerning this draft guide), is “Atmospheric Relative Concentrations for Control Room Radiological Habitability Assessments at Nuclear Power Plants.” This draft guide is being developed to provide guidance on determining atmospheric relative concentration (X/Q) values in support of design basis control room radiological habitability assessments at nuclear power plants. This guide describes methods acceptable to the NRC staff for determining X/Q values that will be used in control room radiological habitability assessments performed in support of applications for licenses and license amendment requests.

This draft guide has not received complete staff approval and does not represent an official NRC staff position.
