Management Of Nuclear Power Plants For Safe Operation

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.

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 Safety Guide provides recommendations and guidance on controlling activities relating to modifications at nuclear power plants so as to reduce risk and to ensure that the configuration of the plant is under control at all times and that the modified configuration conforms to the approved basis for granting an operating licence. The recommendations cover the whole process from conception to completion for modifications to structures, systems and components, operational limits and conditions, procedures and software, and the management systems and tools for plant operation. The Safety Guide recommends how to meet the requirements established in Safety Standards Series No. NS-R-2, The Safety of Nuclear Power Plants: Operation (2000).

Provides recommendations on setting up an operating organisation for nuclear power plants so as to facilitate their safe operation, and on the organisational elements necessary for a strong safety culture and an international level of performance.

Written for use by regulatory bodies and the operating organizations of nuclear power plants, this Safety Guide addresses the commissioning, operation and preparation for decommissioning stages for a nuclear power plant. The role of the operating organization in the siting, design, manufacturing and construction of a nuclear power plant is outside the scope. In most States, the operating organization is the legal entity responsible for safety, financial and commercial obligations, as well as other obligations that are connected with the operation of a nuclear power plant. This Safety Guide is solely concerned with those responsibilities and obligations that are necessary to ensure the safe operation of the nuclear power plant(s) under the control of the operating organization.
