Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
Experience of criticality accidents and evidence of operations history worldwide has indicated that
human errors on different levels (management, operations staff, and/or operations supervisors),
through lack of understanding or ignorance of nuclear criticality safety, have contributed to accidents.
In order to maintain nuclear criticality safety for facilities handling and processing fissile material it is
necessary to ensure the operations staff, operations supervisors, and management are suitably trained
in nuclear criticality safety. This document was developed in response to demand for a definition of the
minimum nuclear criticality safety training requirements for operations staff, operations supervisors,
and management.
This training is distinct from that of th
