DG-4034, Page 15 1.2.2.3 Considerations, Regulatory Experience, and Staff Position In 40 CFR Part 190, the EPA limits the radiation releases and doses to the public from the normal operations of commercial nuclear power plants and other uranium fuel cycle facilities (the facilities involved in the manufacture and use of uranium fuel for generating electrical power). In addition, the regulation specifies limits on the quantity of radioactive materials entering the general environment per gigawatt-year of electricity produced. The NRC has developed regulations (10 CFR part 20) and guidance (RG 1.109, RG 1.111) to ensure that these limits are not exceeded. The atmospheric conditions at a site should provide sufficient dispersion of radioactive materials released during a postulated accident to reduce the radiation exposures of
