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

Chapter 1. Scope

1. This technical regulation "Nuclear and Radiation Safety of Nuclear Power Plants" (further - the Technical regulation) is developed according to the subitem 8) of part one of article 6 of the Law of the Republic of Kazakhstan "About radiation safety of the population" and establishes requirements to ensuring nuclear and radiation safety of nuclear power plants (further - AS).

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 AS developers at stage of development of the project documentation EXPERT.

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 of AS, 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 of AS.

6. Sources of external radiation scale, beta radiators of different energies is nuclear fuel and products of its division, induced the activity of the heat carrier, designs, details of the reactor, products of their corrosion irradiated in active zone the materials and samples contaminated by radioactive materials of surface of rooms, production equipment and tools, packagings, overalls and additional resources of individual protection.

7. Source of neutron radiation is the active zone of the reactor in which, all range of neutrons - from bystry to thermal is implemented. Impact of neutrons is possible in the reactor hall during the operation of the reactor and near experimental channels in case of conclusion of neutron bunches for protection. On the stopped reactor starting sources, and also ampoules with transuranium isotopes in case of their destruction in case of audit and repair of processing equipment can be source of neutrons.

8. Sources of radioactive aerosols are nuclear fuel, the activated heat carrier, the irradiated materials placed in technology contours.

9. Sources of radioactive gases are:

1) the argon-41, which is formed in case of the radiation of the argon-40, which is airborne, filling constructive cavities of systems of the reactor or the attendee as impurity in the gases used for the technology purposes, liquids and heat carriers;

2) fragmental gaseous and easily flying fission products such as xenon, krypton, iodine and so on. The active zone of the reactor, contour of the heat carrier and gas systems is source of their allocation in the atmosphere of the working area in case of violation of hermeticity of designs or in case of insufficiently effective system operation of technology ventilation;

3) products of activation of the heat carrier and decelerator.

10. In this Technical regulation terms according to legislations of the Republic of Kazakhstan in the field of technical regulation and use of atomic energy, and also the following terms and determinations are applied:

1) accident - breakdown of service of nuclear power plant in case of which there was exit of radioactive products and (or) ionizing radiation for the borders provided by the project for normal operation in the quantities exceeding the set limits of safe operation. Accident is characterized by initial event, ways of course and effects;

2) emergency - the condition of nuclear power plant which is characterized by violation of limits and (or) conditions of safe operation, did not turn into accident;

3) administration of nuclear power plant - heads and other officials who are given the rights, obligations and responsibility for operation of nuclear power plant;

13) body of impact on reactivity – the device in the form of elements with firm filler which change of provision provides change of reactivity of the nuclear reactor;

14) reactor installation - the complex of systems and elements of nuclear power plant intended for transformation of nuclear energy in thermal, which is turning on the reactor and directly related systems necessary for its normal operation and maintenance in safe condition;

15) physical start-up - the stage of input of the nuclear reactor in operation including loading of the reactor nuclear fuel, achievement of critical condition of the reactor and accomplishment of necessary physical experiments on power level in case of which the heat sink from the reactor is performed due to natural heatlosses (dispersion);

16) energy start-up - the stage of input of nuclear power plant in operation in case of which nuclear power plant begins to make energy according to the project documentation and is performed check of work of nuclear power plant on power levels up to the level established for commercial operation;
