Technical regulation "Nuclear and Radiation Safety"

Chapter 1. Scope

1. This technical regulation "Nuclear and Radiation Safety" (further – the Technical regulation) establishes requirements to nuclear and radiation safety for nuclear, radiation and electrophysical installations (further – YaREU).

2. Radiation-hazardous factors for personnel, the population and the environment in the conditions of normal operation of YaREU, in case of accidents and in case of mitigation of consequences of accidents are external x-ray, 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 YaREU.

3. On degree of radiation hazard of YaREU are subdivided into four categories:

1) installations on which in case of accident perhaps radiative effects on the population outside their sanitary protection zone belong to the 1st category;

2) installations on which in case of accident the radiative effects are limited to the territory of their sanitary protection zone belong to the 2nd category;

3) installations which radiative effects are limited to the platform of their placement belong to the 3rd category;

4) installations which radiative effects are limited only to rooms or workplace where the works connected with implementation of activities with use of atomic energy are carried out belong to the 4th category.

4. The category of radiation hazard and safety of installation is proved in the YaREU project.

5. If installation consists of several objects within the YaREU platform, the category of radiation hazard is established on the highest of reasonable categories of radiation hazard of each of objects.

6. For the purpose of differentiation of the quality requirements shown to systems and the YaREU elements and reliability four classes of safety of the YaREU elements are established:

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. 3 belong to the class of safety: the elements which are not carried to classes 1 and 2; 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.

4) Class of safety 4. The elements of normal operation of YaREU which are not influencing safety and are not carried to safety classes 1, 2 or 3 belong to the class of safety 4.

The elements used for management of accident, which did not enter safety classes 1, 2 or 3, also belong to the class of safety 4.

7. If any element at the same time contains signs of different classes, then it needs to be carried to higher class of safety. The welded connections, locking bodies and safety devices dividing elements of different classes of safety need to be referred to higher class.

8. Belonging of elements to safety classes 1, 2 and 3 and the requirements applied to them needs to be specified in documentation development, production and delivery of systems and the YaREU elements.

9. Classification designation reflects element belonging to safety class – 1, 2, 3.

10. Classification designation will be added with the symbol reflecting purpose of element:

N – element of normal operation;

З – protective;

L – localizing;

About – providing;

And – the initiating security system element.

If the element has several appointments, then all of them enter its designation. For example, 2H – element of normal operation, class of safety 2.

11. 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 YaREU 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) management of accident - the actions directed to transfer of YaREU in controlled safe condition, prevention of development of project accidents in beyond design basis and on alleviation of the consequences of beyond design basis accidents;

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

4) way of course of accident - the sequence of conditions of systems and the YaREU elements in accident development;

5) systems, elements of normal operation – the systems, elements intended for implementation of normal operation;

6) initial event - single refusal in the YaREU systems, the external event or human error which lead to violation of normal operation and can lead to violation of limits and (or) conditions of safe operation. The initial event includes all dependent refusals which are its consequence;

7) the principle of variety - the principle of increase in reliability of systems by application in different systems (or within one system in different channels) the different means and (or) similar means based on the different principles of action for implementation of the set function;

8) hermetic cover - set of elements of building and other constructions which, protecting space around YaREU, form the border provided by the project and interfere with distribution of radioactive materials to the environment in the quantities exceeding the set limits. The space closed by hermetic cover can form one or several hermetic rooms;

9) the passive device, element - the device, element, with mechanical moving parts or without mechanical moving parts which functioning is connected only with the event which caused its work and does not depend on operation of other, active device;

10) refusals for the general reason - the refusals of two and more systems (elements) arising owing to the same reason;

11) refusal single - refusal, failure of one element of system;
