  The department of mathematical simulation and research into the nuclear processes has been established on the base of computer-aided design (CAD) laboratory in 1993.
  The department activity was aimed to developing calculation methods using mathematical and simulation modeling. As a result, a great number of works on the nuclear process simulation and experimental data processing were carried out.
  The methods developed can also be used for solving applied problems in various fields of solid-state physics, plasma physics, energetics and medicine. A not quit complete list of problems that the researchers of the department have been dealing with recently is given below.
  1. Application of mathematical simulation techniques for developing experimental installations and studying the nuclear processes (Figure 1)
  2. Development of effective models and techniques for evaluating the environmental impact of radiation hazardous objects, including the spent fuel storage and transport facilities, spent fuel and radioactive waste storage containers of various types (Figure 2)
  3. Mathematical methods for diagnosis and prediction of the state of nuclear power engineering (Figure 3)
  4. Development of effective models and techniques for the purpose of applying advanced radiotechnologies in medicine for medical isotope production, cancer detection and treatment and to ensure radiation and environmental safety of available nuclear medical equipment (Figure 4, 5, 6)
  5. Development of cooling/conditioning systems for a compact lithium-ion battery module (Figure 7)
  6. Development of effective techniques to ensure the radiation and nuclear safety of next- generation nuclear installations and other radiation hazard facilities (Figure 8)
  7. Development of effective neutron- and gamma radiography techniques to detect nuclear weapons and to perform the non-destructive control of solid-fuel accelerators with expired guaranteed storage (Figure 9)
  8. Development of theoretical operation methods and mathematical simulation of high- performance nuclear radiation detectors based on the latest semiconductor and scintillation materials for use in scientific research and nuclear medicine
  9. Development of mathematical models, methods and technologies for simulation modeling of toroidal magnetic systems
  10. Applying mathematical modeling techniques to study the heat condition of surface in the process of coating deposition
  11. Development of effective techniques for localization of an unauthorized access to the gas condensate and petroleum pipe line using the neutron-nuclear method
  12. Mathematical simulation of a robotic parachute system in a controlled flight
  13. Development of a procedure for determining the efficiency of the decontamination of adsorbent, used in ventilation and air purification systems at NPP of Ukraine, from methyl iodide by applying non-radioactive materials
  14. Development of a technique for measuring the efficiency of the high-performance air (aerosol) filters, installed in the NPP ventilation systems, during routine inspections
  The researchers of the department have implemented more than 100 research and development projects. According to the results of the research carried out in the department, more than 400 scientific papers have been published in domestic and foreign scientific journals, 7 patents have been obtained, 5 Ph.D. dissertations have been defended. Currently, among the department's staff there are: 1 Dr. in Techn. Sci, 5 Ph.D. in Phys.-Mat. Sci, 2 Ph.D. in Techn. Sci.
