The purpose of SSG is to provide recommendations on how to meet the specific safety requirements for ensuring subcriticality when dealing with fissile material in the handling, processing, storage, transport and disposal of these materials and for planning the response to criticality accidents.

Janu Recommendations for Criticality Safety in Handling and Processing Fissile Materials Procedures, technical criteria and evaluation philosophy which should be observed in all operations with fissile materials outside the cores of nuclear reactors but within the boundaries of nuclear.

In the past, criticality safety analyses related to the handling and storage of fissile materials were obtained from critical experiments, nuclear safety guides, and handbooks.

Criticality is an uncontrolled nuclear chain reaction (divergence) within fissile materials, which are the odd-numbered isotopes of uranium and plutonium ( U, U, Pu and Pu). The risk of criticality is due to the presence of a significant amount of fissile material in some part of the facility and this is therefore broken down into several units so that adequate control modes may.

SSG) STI/PUB/ ISBN –92–0––9 Includes bibliographical references. Criticality. In nuclear facilities processing or storing fissile material, provisions are made to avert the risk of criticality. The purpose of a criticality safety analysis is to ensure that the measures taken are adequate to prevent criticality accidents.

ISO specifies the basic principles and limitations which govern operations with fissile materials. It discusses general nuclear criticality safety criteria for equipment design and for the development of operating controls, while providing guidance for the assessment of procedures, equipment, and operations.

Radioactive material containing fissile nuclides is typically termed fissile material and criticality safety during the transport of such material must be ensured in order to protect workers and the public from the radiological effects of an unanticipated nuclear criticality event.

Fissile nuclides are defined to be U, U, Pu and PuGuidance for the prevention of criticality accidents in the handling, storing, processing, and transporting of fissionable materials is presented in the American National Standard for Nuclear Criticality Safety in Operations with Fissionable Materials Outside Reactors, American National Standards Institute/American Nuclear Society (ANSI/ANS)  Chemical and metallurgical operations involving plutonium and other nuclear materials account for most activities performed at the Los Alamos National Laboratory's Plutonium Facility (PF-4).

The presence of large quantities of fissile materials in numerous forms at PF-4 makes it necessary to maintain an active criticality safety program. The LANL Nuclear Criticality Safety (NCS) Program.
