NRC
• 10 CFR 20 Standards for Radiation Protection• Regulates the use and licensing of radioactive
material• Does not regulate disposal of the material
![Page 10: History of waste disposal. 2 J.H. Saling and A.W. Fentiman, “Radioactive Waste Management,” Second Edition, (Taylor & Francis, NY London) 2002](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649da25503460f94a8f644/html5/thumbnails/10.jpg)

DoE
• Does not have to follow NRC and other agencies but does
• Responsible for all DoE generated wastes and well as civilian spent fuel Nuclear Waste Policy Act (NWPA) 1982
• Takes care of it s own waste• Develops new waste disposal techniques
![Page 12: History of waste disposal. 2 J.H. Saling and A.W. Fentiman, “Radioactive Waste Management,” Second Edition, (Taylor & Francis, NY London) 2002](https://reader035.vdocuments.net/reader035/viewer/2022062407/56649da25503460f94a8f644/html5/thumbnails/12.jpg)
EPA
• Regulates standards for off site releases of radioactive materials
• NWPA states that EPA will promulgate applicable standards for the protection of the environment– Air– Water

ANSI
• Standards for any process that involves radioactive waste
• 55.1-1979 Solid radioactive waste Processing systems for Light Water-Cooled Reactors
• 55.4-1979 Gaseous radioactive waste Processing systems for Light Water-Cooled Reactors
• 55.6-1979 Liquid radioactive waste Processing systems for Light Water-Cooled Reactors

Agreement States
• Agreement between the NRC and State that the State will regulate their own material.
• Some material is not regulated by State• Low-Level Radioactive Waste Policy
Amendments Act (1985)• Made states responsible for waste disposal• Compacts
