This report is a formal presentation of the philosophical and tech nical bases used to establish ex-reactor criticality limits and controls at the Hanford Engineering Development Laboratory, It is intended prima rily as a guide for persons in the Nuclear Safety organization who are directly concerned with establishing criticality safety limits, but should be useful to others who are interested in the types of controls used. Applications of these criteria must be reviewed and approved by an exper ienced criticality safety specialist in the Nuclear Safety Organization prior to use. Handling and storage of fissionable materials outside nuclear reactors must be performed in a manner which precludes a nuclear chain reaction. An accidental chain reaction could result in serious or fatal radiation exposure to nearby personnel, contaminate facilities, cause shutdown of needed facilities, and result in work delays. The goal of the criticality safety program is to avoid accidental criticality through the use of proper facility design and administrative controls.
