Circular 30/2012/TT-BKHCN stipulates 05 requirements for designs of nuclear power plants in Vietnam, including:

* Requirements of systems that contain fissile materials and radioactive materials

The systems in the nuclear power plant designed to contain fissile materials and radioactive materials shall be able to:

- Prevent the occurrence of events that could lead to a loss of control and radioactive release to the environment;

- Prevent criticality and overheating;

- Keep the radioactive releases below acceptable limits and as low as reasonably achievable in any situation;

- Mitigate the radiological consequences of accidents.

* Requirements of radioactive waste management and the decommissioning of the nuclear power plant

The requirements of radioactive waste management and the decommissioning the nuclear power plant must be consider at the design stage, including:

- The selection of materials to minimize the generation of radioactive waste;

- The facilities necessary for the treatment and storage of radioactive waste generated during the operation and decommissioning of the nuclear power plant;

- The easy access and the means for handling.

* Requirements of escape routes

- The nuclear power plant must be provided with a sufficient number of escape routes, clearly marked, with emergency lighting, ventilation and other conditions essential to the safe use of these escape routes in an emergency.

- The escape routes from the nuclear power plant must satisfy the requirements of competent State management agencies for radiation zones, fire protection, industrial safety, and nuclear power plant security.

- At least one escape route shall be available from a workplace or an occupied area in an accident or even simultaneous accidents.

* Requirements of access to the nuclear power plant and prevention of unauthorized acts

- The nuclear power plant shall be isolated from its surroundings with a suitable zoning. Various structural systems shall be provided so that access to the plant can be controlled.

- The zoning prescribed in Clause 1 of Article 29 of Circular 30/2012/TT-BKHCN ust take due account of access to the nuclear power plant in accident conditions for taking emergency response measures.

- The zoning prescribed in Clause 1 of Article 29 of Circular 30/2012/TT-BKHCN must take due account of the control of access to the plant and prevention of unauthorized access to or interference with the equipment of the plant, especially the items important to safety.

More details can be found in Circular 30/2012/TT-BKHCN, which comes into force from February 11, 2013.
