Content:
regulations contain no exceptions with regard to the applicability of 10 CFR 20.1406 for license, design certification, and design approval applications submitted after August 20, 1997 other than the exception for early site permits and license renewals. Even applications that do not deal with large or significant amounts of radioactive material need to address the minimization and facilitation provisions of the regulations, but they should do so using common sense and good judgment. As seen in Figure 1, if a facility will store or handle large volumes of dispersible radioactive material, then the applicant should consider the full range of the measures found in the guide. If the facility will handle significant amounts of dispersible radioactive material (e.g., amounts that, if released, might result in extensive cleanup activities either during operation or decommissioning), the form of the material that will be released needs to be considered. A facility which primarily stores or handles liquid radioactive material, for example, should give consideration to the provisions in this guide to prevent and control inadvertent liquid releases. Similarly, for a gas, consideration should be given to the provisions to control inadvertent gaseous releases. Conceptually, this also applies to dry solid radioactive wastes, with consideration taken for obvious differences in chemical and physical forms. RG 4.21, Page 4 Figure 1. Decision Paths for Determining the Applicability of Regulatory Guide 4.21 Table 1 provides further information that may be useful in determining the applicability of the guide. This table is based on the type of facility, the physical form of the radioactive material, the material’s half-life, and the facility’s inventory of the material. For major, complex facilities with significant inventories of radioactive materials, such as a commercial nuclear power plant, enrichment facility, fuel fabrication facility, or a radioactive waste facility (Table
