Radiological safety

Staff radiation exposure The radioactivity level to which the staff is exposed is very low for several reasons the pool design of the reactor which coniine the primary drcuit, the near absence of fission products because of the small number of cladding lures and early detection, identification and extraction from the core good protection conditions for handling not only fuel but also components like pumps or IHXs The main dose exposures result from specific inspections (storage drum, reactor vessel,. .) or maintenance operations (fuel transfer device, primary circuit, IHX.) Since 1974, the total dose equivalent integrated by the plant staff and contractors is 1,33 manSv (133 man.rem). 

Radioactive wastes. These are also very low. (1) solid waste, essentially parts of fuel subassembly frames after dismantling, (2) liquid waste coming from subassembly pump and IHX cleaning (these are not released directly from the plant but are transported to and treated at the COGEMA MARCOULE Center nearby), and (3) gaseous waste which follows the activity released from cladding failures, and so is very low. Most of the time, the activity is at background level.

Spent fuel casks are of type B. For the movement of spent fuel, computer tracking systems are used. State radiological safety units are informed of shipments of spent fuel and other high activity radioactive materials so that these units may respond in case of accident. 

The licensing process consists of two steps construction and operating license that must be completed before fuel loading. Licensing covers radiological safety, environmental protection, and antitru,st considerations. Activities not defined as production or utilization of special nuclear material (SNM), use simple one-step. Materials Licenses, for the possession of radioactive materials. Examples are uranium mills, solution recovery plants, UO fabrication plants, interim spent fuel storage, and isotopic separation plants. 

An issue with equal significance for the Dnepropetrovsk district is the provision of radiological safety for the population. 

The sanitary and epidemiological service of the Dnepropetrovsk district also provides supervision for the observance of radiological safety rates during operation of ionizing radiation sources in public health, industry and other industrial branches. It carries out studies on food products, drinking water, construction material, gamma-survey of the territory.

The Notification Convention applies in the event of any accident involving facilities or activities of a State Party, or those under its jurisdiction or control, from which a release of radioactive material occurs or is likely to occur, and which has resulted or may result in an international transboundary release that could be of radiological safety significance for another State. A State Party involved in an accident covered by the Convention is obliged to immediately notify, directly or through the IAEA, those States which are or may be physically affected. 

Process Operation—Considerations from Radiological Safety Point of View.846... 

In view of the radiological safety the personal contact with operating installation should be minimized. The location of data acquisition and control systems has to be planned in separate room, away from places of potential contamination. However, the necessity of eventual periodic sampling has to be taken into account, too. The sampling points have to be located in the places with easy operator access and arranged in a way eliminating leaks and contamination. 

This group forms the nucleus and is considered a minimum. Others with special skills may need to be involved for some reviews, such as the Site Industrial Hygienist, the Site Radiological Safety Officer, an instrumentation engineer, or a person experienced with explosion hazards.

A thermionic space reactor system does not suffer a radiological safety disadvantage compared with a thermoelectric space reactor system since both systems are laimched cold and neither reactor is started until a nuclear safe orbit has been achieved. The radiological hazards associated with the launch of a cold reactor system without a fission product inventroy are significantly less than those of a launch of a radioisotope thermoelectric generator.

While such doses would no longer be acceptable, the adequacy of the current radiation level limits, in terms of radiological safety, has been confirmed by a number of surveys where radiation exposure of transport workers has been determined [29-32] and by an assessment performed by the IAEA in 1985 [33]. However, it is recognized that the permitted radiation levels around packages and conveyances do not alone ensure acceptably low doses, and the Regulations also require the establishment of radiation protection programmes (para. 301) and the periodic assessment of radiation doses to persons due to the transport of radioactive material (para. 304).
