03-14685. Regulatory Guide; Issuance, Availability

The Nuclear Regulatory Commission (NRC) has issued three guides 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 its review of applications for permits and licenses, and data needed by the NRC staff in its review of applications for permits and licenses.

Regulatory Guide 1.195, “Methods and Assumptions for Evaluating Radiological Consequences of Design Basis Accidents at Light-Water Nuclear Power Reactors,” provides guidance to licensees of operating power reactors on methods and assumptions for performing evaluations of fission product releases and radiological consequences of several postulated light-water reactor design basis accidents.

Regulatory Guide 1.196, “Control Room Habitability at Light-Water Nuclear Power Reactors,” provides guidance and criteria acceptable to the NRC staff for implementing the NRC's regulations regarding control room habitability.

Regulatory Guide 1.197, “Demonstrating Control Room Envelope Integrity at Nuclear Power Reactors,” provides an approach acceptable to the NRC staff for measuring inleakage into the control room and associated rooms and areas at nuclear power reactors.
