Approach to design for accident conditions

The design objectives for accident conditions are to limit to acceptable levels (1) the risks to the pubhc from possible releases of radioactive material from the nuclear power plant and (2) the risks to site personnel from these releases and from direct radiation exposure. These design objectives should be achieved by means of high quality design and special features, such as safety systems and protection systems, that are incorporated into the design of the 

To achieve the design objectives mentioned, the necessary design provisions and procedures (e.g. for access to the control room, maintenance of essential equipment or process sampling) should be such as to enable the plant operators to manage the situation adequately in an accident. Recommendations on how to protect site personnel under accident conditions are provided in Section 10. 

Practices that are similar to those used for operational states should also be used to ensure that proper plant design is achieved to provide adequate radiation protection for site personnel and the public under accident conditions. A safety culture should be established to ensure that safety matters are given the highest priority and that regulatory requirements on releases of radioactive material under accident conditions are met with adequate margins.
