Content:
mplex 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 1, Groups 1 and 2), the guide should assist an applicant in meeting the requirements of 10 CFR 20.1406. For smaller facilities that do not have large inventories, especially ones in which the material has a short half-life or is in the form of a sealed source (e.g., Table 1, Group 4), an applicant would need to consider only those design measures and operational procedures that directly apply to the type of radioactive material and processes to be authorized and the potential for contamination of the facility or environment. In this case, applicants should focus on historical information and process knowledge that reflect the likelihood of contamination of the facility and environment to identify the systems that should be designed and operated consistent with 10 CFR 20.1406. Since applicability of the guidance is a facility-by-facility decision, early consultation with the appropriate regulatory agency is strongly advised. RG 4.21, Page 5 Table 1.
