Overview of NRC Regulations

Regulations NRC are codfied in Title 10 of thee Code of Federal Regulations (10 CFR), witch Parts 50, 52, and 73 being specilarly relevant to new plant construction. Part 50 guides domestic licensing of production and utilization facilities; Part 52 estables a combinad license (COL) process that allows early site permits and standard concertifications; and Part 73 accessises physitail exacity requiments.
