This publication describes an evaluation approach to determine a Member State’s status in developing and implementing the infrastructure areas necessary for a nuclear power plant (NPP) project. It has been written to be used by any interested Member State for self-evaluation as well as for external reviews with the participation of the IAEA and of independent external experts. Other organizations, such as donors, suppliers, nuclear energy agencies and operator organizations, may also use this publication to provide confidence that a Member State is adequately developing the infrastructure necessary to regulate, construct and safely operate an NPP.
