Standards for Combustible Gas Control System in Light-Water-Cooled Power Reactors

The Nuclear Regulatory Commission (NRC) is making available the draft wording of a possible amendment of its regulations. The proposal would amend 10 CFR 50.44, "Standards for combustible gas control system in light-water-cooled power reactors," and associated regulations based on experience gained from a fundamental reevaluation of the need for the regulation, the application of risk insights, and the incorporation of performance-based concepts, to the degree practicable. The proposed changes effectively "rebaselines" the existing regulation for current licensees and consolidates combustible gas control regulations for future applicants and licensees. The changes should reduce the regulatory burden for all applicants and licensees and improve the effectiveness of 10 CFR 50.44. Additional conforming changes to 10 CFR 50.34, 50.46, and 10 CFR part 52 are also identified. The availability of the draft wording is intended to inform stakeholders of the current status of the NRC staff's activities to amend 10 CFR 50.44 and to provide stakeholders the opportunity to comment on the draft changes. The NRC staff has also provided additional information within the body of the draft rule lang
