Figure 1 illustrates the options for how power reactors and non-power reactors can be licensed as commercial and industrial facilities or for research and development activities using the new performance-based criteria .
The revision would amend guidance to provide risk-informed and performance-based criteria to assess population-related siting issues for advanced reactors , while also identifying hypothetical major accidents that applicants must evaluate to satisfy the new approach.
Nuclear Power Reactor Source Term
Guidance and information for developing advanced reactor source term Introduction This web page provides a selected collection of information about nuclear power reactor source term for stakeholders considering pre-application engagements with the NRC or developing applications for new nuclear power reactors under Parts 50 and 52.
Developing a new regulatory framework for advanced reactors
The American Nuclear Society's Risk-informed, Performance-based Principles and Policy Committee (RP3C) on March 29 held another presentation in its monthly Community of Practice (CoP) series. The presenter, Patrick White with the Nuclear Innovation Alliance (NIA), talked about the current status of efforts to develop a new regulatory framework for advanced reactors—known as 10 CFR Part 53 ...
For example, a support Enzo can do ♥♥♥♥ with a non- attribute reactor since you won't build him on skill power. You would be happy with a GOLD duration up and skill cooldown on a fire based reactor on enzo, instead of a non- attribute one giving you skill critical and colossus skill power.
NRC unveils Part 53 final rule
A long time coming: Part 53 is the first new reactor licensing framework issued by the NRC since 1989, when the agency introduced Part 52. NRC officials added that it is the first major update to reactor licensing standards since 1956, when the Atomic Energy Commission (the NRC's predecessor) issued Part 50.
Key Takeaways On March 25, 2026, the U.S. Nuclear Regulatory Commission (NRC) approved a final rule establishing a new risk-informed, performance-based, and technology-inclusive regulatory framework for licensing commercial nuclear plants. This is the first new set of regulations to address initial reactor licensing since 1989, when the NRC created Part 52, and the first major update to ...
PDF Updated NRC Seeks Comment on Advanced Reactor Licensing Proposed Rule
The Nuclear Regulatory Commission is seeking comment on a proposed rule and draft guidance for a commercial nuclear power plant licensing process that uses risk insights to set performance standards applicable to any reactor technology.
