The objective of this Safety Guide is to provide guidance on the establishment of a framework for safety in accordance with the IAEA safety standards for States deciding on and preparing to embark on a nuclear power programme. In this regard@ it proposes 200 safety related actions to be taken in the first three phases of the development of the nuclear power programme@ to achieve the foundation for a high level of safety throughout the entire lifetime of the nuclear power plant@ including safety in the associated management of radioactive waste and spent fuel@ and safety in decommissioning. This Safety Guide is intended to contribute to the building of leadership and management for safety and of a safety culture. It is intended for use as guidance for self-assessment by all organizations involved in the development of a safety infrastructure. The government@ through the legal system@ establishes national policy for safety by means of different instruments@ statutes and laws. The regulatory body@ as designated by the government@ is charged with the implementation of policies through a regulatory programme or a strategy set forth in its regulations or standards. The government@ through the legal system@ determines the specific functions of the regulatory body and the allocation of responsibilities. For example@ the government establishes laws and adopts policies pertaining to safety@ whereas the regulatory body develops plans and promulgates regulations in execution of such laws or policies. In addition@ the government establishes laws and adopts policies specifying the responsibilities and functions of different governmental entities in respect of safety and emergency preparedness and response@ whereas the regulatory body establishes a system to provide for effective coordination. The recommendations made in this Safety Guide are to be understood in the context of these respective functions@ although some flexibility may be necessary in following them@ depending on the particular national circumstances.
