Mathematical aspects of remote assessment of the radiation state of contaminated areas

The article examines global trends in the development of the nuclear power industry. It includes the following: extending the operating life of nuclear power units; development of atomic energy in the context of the Paris Agreement; development of nuclear-hydrogen energy; synergistic interaction of renewable energy sources and nuclear power plants; introduction of new reactor technologies. The attitude of different countries of the world to atomic energy is described. It is determined that China and India are the leaders in developing nuclear power. It was determined that small modular reactors are considered transformative reactors that will contribute to the further development of atomic energy in the world. The advantages of small modular reactors in comparison with reactors of large capacity are described, and recommendations for selecting small modular reactors for Ukraine are formulated. Installation of small modular reactors at the operational sites of the NPPs of Ukraine can reduce the financial costs of their construction. Therefore, it will contribute to the sustainable development of the nuclear energy industry of Ukraine.

“…Presented studies can be used for organizing the monitoring of the territories with man-made radioactive waste, for instance affected by accidents at nuclear NPPs [14]. As is well known [6], the territory of the Chornobyl Exclusion Zone contains huge amounts of spent nuclear fuel, radioactive waste, and its temporary localization. These storage facilities consist of complex "Vector", radioactive waste disposal points "Buryakivka", "Pidlisnyi", "ChNPP Stage III", nine temporary radioactive waste confinement sites with a total area about 10 hectares and include nearsurface disposal facility, trenches, and mound storages.…”

Mathematical tools of solving the problem of restoring the surface distribution of radiation pollution based on remote measurement data

et al. 2023

The modern achievements in the construction of small flying machines cause the active development of remote monitoring, in particular geophysical airborne gamma-ray spectrometer surveying. Such observations are important, since large amounts of man-made radioactive materials get into the environment, especially during accidents like at the Chornobyl or Fukushima nuclear plants. On the other hand, the natural distribution of radioactive sources is inhomogeneous and can provide us with useful information about the soil structure. One of the problems appearing at the handle of information collected with unmanned aerial vehicles concerns the correction of readings to identify the peculiarities of gamma-ray fields. To perform this, the analytical method based on the solution of the inverse problem formulated in terms of integral relation is used. In this research, to reconstruct the surface distribution of the gamma-ray field, the Tikhonov and Landweber techniques are applied. It is shown that these algorithms allow one to distinguish radioactive hot-spots located closely.

“…The first sub-section focuses on radiation pollution caused by war and nuclear power plants. The talks in this sub-section present mathematical tools for restoring the surface distribution of radiation pollution based on remote measurement data [252,253], a conceptual scheme for creating environmentally friendly Gd-containing neutron-absorbing nanocomposites [254], a factor-criterion model for selecting the optimal option for transforming the "Shelter" object into an environmentally safe system [255], and the formation of the carbonate system of circulating cooling water of the Rivne NPP and its influence on the surface waters pH levels of the Styr River [256]. These talks provide novel approaches and techniques for reducing the radiation exposure and contamination of humans and the environment.…”
