The draft regulatory analysis prepared for the revision to 10 CFR 50.44, “Standards for Combustible Gas Control System in Light-water-Cooled Power Reactors,” provides the regulatory basis for this guide and examines the costs and benefits for the rule as implemented by the guide. A copy of this regulatory analysis is available for inspection or copying for a fee in the NRC Public Document Room, located at 11555 Rockville Pike (first floor), Rockville, Maryland.
