This publication 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 for the design
of a nuclear power plant. It will be useful for organizations involved in design, manufacture, construction, modification,
maintenance, operation and decommissioning of nuclear power plants, as well as for regulatory bodies. A review of Safety Requirements
publications was commenced in 2011 following the accident in the Fukushima Daiichi nuclear power plant in Japan. The review
revealed no significant areas of weakness and resulted in just a small set of amendments to strengthen the requirements and
facilitate their implementation, which are contained in the present publication.
