ANSI/ANS-8.3-1986;W1996 (W=Withdrawn): Criticality Accident Alarm System

This standard is applicable to all operations with plutonium, ²³³U, uranium enriched in ²³⁵U, and other fissionable materials in which inadvertent criticality may occur and cause the exposure of personnel to unacceptable amounts of radiation.  This standard does not require separate additional instrumentation when the operating instrumentation of facilities, such as nuclear reactors or critical experiments, meets the requirement of this standard.
