Standardization and promotion of good practices associated with the planning, design, construction, operation and decommissioning of installations, processes and technologies involving radioactive materials

Nuclear installations, processes and technologies include: the Fuel Cycle including mining, ex-reactor nuclear criticality safety, analytical methodologies, transport of radioactive materials, materials characterisation, radioactive waste management, decommissioning and geological disposal.

Excluded :

  • Specific enabling technologies and techniques for non-peaceful applications:
  • Sealed sources, radiation processing, nuclear power plants and research reactors

    The potential for a criticality accident outside reactor cores should nevertheless be evaluated.
