Technical regulation "Nuclear and Radiation Safety of Nuclear Power Plants"

1. Scope

1. This technical regulation "Nuclear and Radiation Safety of Nuclear Power Plants" (further - the Technical regulation) establishes requirements to ensuring nuclear and radiation safety of nuclear power plants (further - the EXPERT).

2. The equipment and pipelines to which requirements of this Technical regulation extend enter the following classes of safety:

1) class of safety 1. Elements which refusals can be initial events of the beyond design basis accidents leading to radiation of personnel and (or) the population, emission (dumping) of radioactive materials in the environment over the limits set for project accidents belong to the class of safety 1;

2) class of safety 2. Elements which refusals can be the initial events leading to project accidents belong to the class of safety 2;

3) class of safety 3. The elements which are not carried to the classes 1 and 2 belong to class of safety 3; the elements containing radioactive and (or) toxic materials which intake to rooms and (or) the environment in case of refusals can exceed the levels established according to regulating documents; the elements performing functions of control of ensuring radiation protection of personnel and the population.

3. The specific nomenclature of the equipment and pipelines with indication of their belonging to classes of safety is established by EXPERTS developers on project stage.

4. The equipment and pipelines, which part products are (details, assembly units), of different groups, concern to group with higher requirements.

5. Radiation-hazardous factors for personnel, the population and the environment in the conditions of normal operation the EXPERT, in case of accidents and in case of mitigation of consequences of accidents are external scale, beta, neutron radiations, inhalation receipt in the organisms of radioactive gases and aerosols contaminated by radioactive materials of surface of rooms, production equipment and tools, packagings, overalls and additional resources of individual protection and also the gaseous, liquid and solid radioactive waste which is formed in case of operation the EXPERT.
