Cullison (301)415-1212 DRAFT REGULATORY GUIDE DG-1117 CONTROL OF COMBUSTIBLE GAS CONCENTRATIONS IN CONTAINMENT A. INTRODUCTION The NRC has issued a proposed revision to Section 50.44, “Standards for Combustible Gas Control System in Light-Water-Cooled Power Reactors,” which will become an amendment to 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities.” This proposed regulation will be applicable to all construction permits or operating licenses under this part, and to all design approvals, design certifications, combined licenses or manufacturing licenses under 10 CFR Part 52, “Early Site Permits; Standard Design Certifications; and Combined Licenses for Nuclear Power Plants,” that are issued after the effective date of the rule. This regulatory guide is being developed to describe methods that would be acceptable to the NRC staff for implementing the proposed Section 50.44. Regulatory guides are issued to describe to the public methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, to explain techniques used by the staff in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations, and compliance with regulatory guides is not required. Regulatory guides are issued in draft form for public comment to involve the public in developing the regulatory positions. Draft regulatory guides have not received complete staff review; they therefore do not represent official NRC staff positions. The information collections contained in this draft regulatory guide are covered by the requirements of 10 CFR Part 50, which were approved by the Office of Management and Budget, approval number 3150-0011. If a means used to impose an information collection does not display a currently valid OMB control number, the NRC may not conduct or sponsor, and a person is not required to respond to, the information collection. 2 B.
