The use of gamma-ray imaging spectrometers at nuclear power plants and other facilities for the purpose of understanding the source term environment has grown sharply in the past 10 years. The primary instrument used at nuclear power plants in the United States is the H-Series unit made by H3D, Inc. The instrument uses 3D-CZT detectors, which are able to provide 1% energy resolution along with...
There is an increasing international focus on the need to optimize decommissioning strategies of nuclear facilities, especially considering the radiological impacts on workers, the general public, and the environment. Assessing and optimizing occupational radiation exposure during the decommissioning of nuclear facilities is important to ensure the safety and health of workers. A major effort...
During the operation, maintenance, decommissioning of nuclear facilities, workers often need to work directly in the radiation environment. Considering the personal dose limit principle in the radiation protection, specific planning is usually carried out prior to the implementation of the work, which requires the radiation protection personnel to obtain the radiation field data of the entire...
More than 80% of occupational exposure in PWR nuclear power plants comes from overhaul, γ Deposition source term is the main source of occupational exposure during nuclear power plant overhaul. As the third generation advanced PWR nuclear power plant, it is necessary to measure and analyze its deposition source term during overhaul, so as to understand the main components of radionuclides in...
In recent decades, China's nuclear power industry has developed rapidly, but the increase in the number of workers has also posed a serious challenge to radiation protection. The visualization and simulation technology of 3D radiation field can construct the radiation field through the measurement data, and carry out 3D visualization of the radiation field, which is an important means of field...
Abstract:
The main objective of this paper is to identify both the importance of and the major factors relevant to, radiation protection procedures during radiological characterization of reactor pool IRT-5000 in order to support the decommissioning planning effort. There are many difficulties and challenges that faced technical Iraqi workers in carrying out this task for several reasons:...
The collective dose of nuclear power plant workers mainly comes from the outage period of nuclear power plant. The corrosion activation products deposited in the pipelines and the radiation dose field formed are the main sources of occupational exposure of workers in the nuclear facilities, and the changes of their numerical value also reflect the operating state of the NPP unit. Therefore, it...
The entry into the new millennium was marked by a new stage in the development of nuclear energy. The revival of global nuclear energy is directly related to the solution of such problems as:
- increase in energy consumption by the population of the planet;
- problems of ecology and climate change.
It is obvious that the above problems require more environmentally friendly energy sources,...
FBTR is a research reactor operating at Kalpakkam, India, with an installed capacity of 40 MWt. The reactor serves as a test bed for irradiation of fuels and materials and provides experience in handling of sodium and reactor operation. It has attained the design power level of 40 MWt in March 2022. The reactor containment building is divided into four zones and further subdivided into cells....
This paper foregrounds that in labour law and labour relations, the main focus of the law and policy drivers is to ensure occupational health and safety. This includes the promotion and maintenance of safe working environment ensuring capacity building and sound employee’s health; improvement of working environment; development of work cultures and organizations to support health and safety in...
Nuclear technology and application in Nigeria is fast developing; Nigeria and many other developing countries use nuclear application in everyday activities, in health sector, agricultural sector, oil and gas Industries, Construction industries, Manufacturing Industries, Education and training. The Federal Government of Nigeria has proposed to construct its first nuclear power plant by...
The international nuclear industry has for many years had an impressive record of controlling and reducing occupational exposure, as measured by average individual exposure and collective dose. Current average worker doses are around 1 mSv per year for the whole nuclear fuel cycle, which is within the variability of natural background radiation. We hope for regulatory acknowledgement of this...
NAC Kazatomprom JSC is the national operator of the Republic of Kazakhstan for the import and export of uranium, rare metals, and nuclear fuel for nuclear power plants. Since 2009, Kazakhstan has been the world leader in natural uranium mining. Kazatomprom, together with subsidiaries, affiliates and joint organizations, is developing 26 sites on the territory of the Republic of Kazakhstan,...
Occupational radiation protection is an area of vital importance during the lifecycle of Nuclear Power Plants (NPPs). Radiation workers are likely to receive exposure mainly during the routine maintenance activities as well as the refueling outages (RFOs). This exposure can be controlled by taking some tangible measures. These measures include regulatory control, licensee's mechanism to...
An adequate radiation protection programme must be established for a nuclear fuel fabrication plant with low enriched uranium in order to ensure the protection of people and the environment from the harmful effects of ionizing radiation. Such a programme should include the establishment of radiation protection groups, dose limitation systems, an adequate classification of working areas, the...
The lessons learned from the Covid-19 Epidemic show that the risk of an epidemic is associated with a rapid spread and unpredictable impact in the future. Large-scale emission events that trigger radiationenter code here emergency response structures and programs can occur at the same time. In fact, the simultaneous occurrence of effective radiological scenarios during an epidemic is quite...
