r Regulatory Commission (NRC) staff considers acceptable for use in assessing abnormal, inadvertent radioactive releases which may result in discharges of contaminated ground water from the subsurface to the unrestricted area at commercial nuclear power plant sites. Applicability This guide is applicable to Title 10 of the Code of Federal Regulations (10 CFR), Part 20, “Standards for Protection against Radiation” (Ref. 1), 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities,” (Ref. 2), 10 CFR Part 52 “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3), and 10 CFR Part 100, “Reactor Site Criteria” (Ref. 4). Applicable Regulations • Title 10 of the Code of Federal Regulations (10 CFR), Part 20, “Standards for Protection against Radiation,” provides standards for protection against ionizing radiation resulting from activities conducted under licenses issued by the NRC. – 10 CFR 20.1406(a) requires that applicants for licenses other than early site permits and manufacturing licenses under 10 CFR Part 52, whose applications are submitted after August 20, 1997, describe in the application how facility design and procedures for operation will minimize, to the extent practicable, contamination of the facility and the environment, facilitate eventual decommissioning, and minimize, to the extent practicable, the generation of radioactive waste. DG-4025, Page 2 – 10 CFR 20.1406(b) requires that applicants for standard design certifications, standard design approvals, and manufacturing licenses under 10 CFR Part 52, whose applications are submitted after August 20, 1997, describe in the application, how facility design will minimize, to the extent practicable, contamination of the facility and the environment, facilitate eventual decommissioning, and minimize, to the extent practicable, the generation of radioactive waste. – 10 CFR 20.1406(c) requires that licensees to the extent practical, conduct
