Criteria for nuclear criticality safety controls in operations where shielding protects personnel - approved 1975

The standard is applicable to operations outside of nuclear reactors with 235U, 233U, 239Pu, and other fissile and fissionable materials in which shielding and containment are provided for protection of personnel, except the assembly of these materials under controlled conditions, such as in critical experiments. Criteria are provided that may be used for criticality control under shielded conditions. The standard does not include the details of administrative procedures for control, which are considered to be management prerogatives, nor details regarding the design of processes and equipment or descriptions of instrumentation for process control
