ANS 8.23-2019 provides criteria for minimizing risks to personnel during emergency response to a nuclear criticality accident outside reactors. The criteria address management and technical staff responsibilities, planning, equipment, evacuation, rescue, reentry, stabilization, classroom training, drills, and exercises. This standard applies to facilities, locations, or activities judged to have credible and non-trivial consequences from a criticality accident. This standard does not apply to nuclear power plant sites or to licensed research reactor facilities, which are addressed by other standards.Keywords:Nuclear Safety, Nuclear Criticality Safety, Nuclear Facility Operations Emergency Planning, Emergency Response, Radiological
