01-4627. Draft Regulatory Guide; Issuance, Availability

The Nuclear Regulatory Commission has issued for public comment a proposed revision of a 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-1087 (which should be mentioned in all correspondence concerning this draft guide), is titled “Evaluating the Habitability of a Nuclear Power Plant Control Room During a Postulated Hazardous Chemical Release.” DG-1087 is a proposed Revision 1 of Regulatory Guide 1.78, and it is being revised to propose guidance on control room habitability during a postulated hazardous chemical release, including chlorine. When Revision 1 of Regulatory Guide 1.78 is issued, it will incorporate and withdraw Regulatory Guide 1.95, “Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release,” since many of the regulatory positions in these two guides are the same or similar.

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