Nuclear criticality safety. Estimation of the number of fissions of a postulated criticality accident1 Scope This International Standard provides a methodology to estimate a reasonably maximal value of the number of fissions of a postulated criticality accident. The fission number estimate, associated with its postulated criticality accident, impacts the accident emergency planning and response because it is used for the estimation of radiation doses and of radioactive materials release. This International Standard does not provide a methodology and
