Criticality Safety

Nuclear Safety Basis

The Office of Nuclear Facility Safety Programs establishes and maintains the DOE requirements for nuclear criticality safety. The DOE detailed requirements for criticality safety are contained in Section 4.3 of the DOE Order 420.1, Facility Safety. Criticality safety requirements are based on the documented safety analysis required by 10 CFR 830, Subpart B. Additionally, guidance for satisfying the DOE requirements is found in the Implementation Guide for the 830 rule and in DOE Standard (STD) 3009-94, chapter six. DOE Guide 421-1 also provides detailed program guidance to criticality practitioners and reviewers.
