Basic Safety Principles For Nuclear Power Plants

The present report is a revision of Safety Series No. 75-INSAG-3 (1988), updating the statements made on the objectives and principles of safe design and operation for electricity generating nuclear power plants. It includes the improvements made in the safety of operating nuclear power plants and identifies the principles underlying the best current safety policies to be applied in future plants. It presents INSAG's understanding of the principles underlying the best current safety policies and practices of the nuclear power industry.

This publication is out of print and superseded by INSAG Series No. 12, Basic Safety Principles for Nuclear Power Plants, 75-INSAG-3 Rev. 1. (STI/PUB/1082)

The basic safety approach of defence in depth and high functional system availability is addressed in this guide. Attention is also paid to the safety implications of operator actions and their consideration in the design.

On the basis of the principles included in the Fundamental Safety Principles, IAEA Safety Standards Series No. SF-1, this Safety Requirements publication establishes requirements applicable to the design of nuclear power plants. It covers the design phase and provides input for the safe operation of the power plant. It elaborates on the safety objective, safety principles and concepts that provide the basis for deriving the safety requirements that must be met for the design of a nuclear power plant. Contents: 1. Introduction; 2. Applying the safety principles and concepts; 3. Management of safety in design; 4. Principal technical requirements; 5. General plant design; 6. Design of specific plant systems.

Establishes requirements applicable to the design of nuclear power plants and elaborates on the safety objective, safety principles and concepts that provide the basis for deriving the safety requirements that must be met. It will be useful for organisations involved in design, manufacture, construction, modification, maintenance, operation and decommissioning of nuclear power plants.

This publication identifies the fundamental safety objective and associated safety principles that underpin the IAEA's safety standards and its related safety programme. They provide the basis for requirements and measures for the protection of people and the environment against radiation risks, the safety of facilities and activities that give rise to radiation risks, including, in particular, nuclear installations and uses of radiation and radioactive sources, the transport of radioactive material and the management of radioactive waste.
