ANSI/ANS-8.10-1983(R88): Criteria for nuclear criticality safety controls in operations with shielding and confinement
- Pacific Northwest National Lab., Richland, WA (United States)
- Los Alamos National Lab., NM (United States)
Guidance for the prevention of criticality accidents in the handling, storing, processing, and transporting of fissionable materials is presented in the American National Standard for Nuclear Criticality Safety in Operations with Fissionable Materials Outside Reactors, American National Standards Institute/American Nuclear Society (ANSI/ANS)-8.1. (This guidance is amplified and complemented in specific ANS-8 standards.) ANSI/ANS-8.1 recognizes that if adequate shielding against radiation and confinement of radioactive materials is provided, the hazards normally attendant with criticality in a facility lacking shielding and confinement are minimized. It is stated in Sec. 4.1.1 of ANSI/ANS-8.1 that {open_quotes}Distinction may be made between shielded and unshielded facilities, and the criteria may be less stringent when adequate shielding and confinement assure the protection of personnel.{close_quotes} This is consistent with the recognition by all safety professionals and stated in ANSI/ANS-8.1 that {open_quotes}Good safety practices must recognize economic considerations ...{close_quotes} ANSI/ANS-8.10 applies to facilities constructed and operated so that operations personnel and the public would be protected from the effects of an accidental criticality if it occurred. When specified protection and confinement criteria are met, reduced conservatism in equipment design and process operation is allowed compared with operations where protection and confinement are not provided. Anyone with an interest in this standard should contact the authors, as a working group will be assembled in the near future to consider possible revisions.
