Licensing Requirements for Microreactors and Other Reactors With Comparable Risk Profiles

What it does

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to establish a risk-informed and performance- based regulatory framework for rapid licensing of new microreactors and other reactors with comparable risk profiles and for high-volume deployment of these reactors. The proposed rule would provide a flexible set of licensing pathways, reduce regulatory burden, and ensure that safety and security requirements remain commensurate with the potential hazards posed by these facilities.

The Nuclear Regulatory Commission's summary, as published in the Federal Register.

What it would change

22 parts of Title 10 of the Code of Federal Regulations:

10 CFR 1, 10 CFR 2, 10 CFR 10, 10 CFR 11, 10 CFR 19, 10 CFR 20, 10 CFR 21, 10 CFR 25, 10 CFR 26, 10 CFR 30, 10 CFR 40, 10 CFR 50, 10 CFR 51, 10 CFR 57, 10 CFR 70, 10 CFR 72, 10 CFR 73, 10 CFR 74, 10 CFR 75, 10 CFR 95, 10 CFR 140, 10 CFR 150
