“…Nuclear power plants (NPP) are source of radionuclides contamination and potential risk to humans and the environment. Identification of the main dose-forming atmospheric discharges of NPP was carried out in [1,2], which showed that the level of contamination depends on the type and design of nuclear reactor. This work aims to summarize the raw data on atmospheric discharges of pressurized water reactors (PWR) and their Russian analogs known as VVER (abbreviation of Russian term "Vodo-vodyanoy energeticheskiy reactor") nuclear reactors in Europe and Russia.…”

Abstract.Comparison of radionuclide specific indicators in airborne discharges to atmosphere from European and Russian nuclear power plants was carried out. The performed analysis allows determining airborne discharge structure and the environmental impact of nuclear power plant with different types of reactor. Analysis of experimental data on radioactive airborne discharges from Russian nuclear power plants is carried out. The nuclear power plants with three different kinds of reactors are investigated. The performed analysis allows determining the list of radionuclides in airborne discharges, which give from 84 to 99 % of radiation exposure population.

“…The results of Monte-Carlo simulation in 4π measurement geometry in the form of calculated theoretical spectra allowed to determine the relation of detection efficiency to the energy of gamma-radiation for spectrometer based on NaI(Tl) scintillation crystal of Ø 63 × 63 mm and Ø 63 × 160 mm size (Figure 2), which is used for calculation of specific activity of most dose-forming radionuclides [20]. One of the most important spectrometer's parameters in any geometry is sensitivity to measured radionuclide or relation of detection efficiency to energy of gamma-radiation.…”

Приборы и методы измерений 2016 , 11, 220030, Minsk, Belarus Received 06.10.2016 Accepted for publication 25.11.2016 Abstract In order to solve the problem of continuous or periodic monitoring of water areas affected by radioactive contamination in the result of scheduled emissions in nuclear power plants or in the result of emergency situations in nuclear fuel cycle plants we need to develop measurement instruments with advanced mathematics and program support to assess the level of radioactive contamination with required accuracy. The aim of theoretical research was to optimize detection device construction, estimate spectrometer metrological parameters in given measurement geometries, and determine effective position of detection device in the process of in situ measurements.This device consists of spectrometric scintillation probe packed into sealed container (detection device) based on NaI(T1) crystal of Ø 63 × 63 mm or Ø 63 × 160 mm size, cable reel with deep-sea cable and a tablet PC for data processing and displaying. The container withstands static hydraulic pressure up to 5 MPa and can be used for measurements at depths of 500 m maximum. Probe measures energy distribution of gammaradiation with energy from 70 keV to 3000 keV. The implemented three-dimensional system for detection device position and orientation determination allows automatic operation of the device (without operator) for water areas or bottom sediment scanning. The spectrometer can output measurement results with threedimensional geographical coordinates as index maps of distribution with necessary resolution and accuracy. Monte Carlo models of spectrometer and controlled objects are developed in order to determine the detector response functions to given radionuclides in given measurement geometries without use of expensive standard measures of activity.Multifunction gamma-spectrometer for in situ radiation monitoring of water areas and bottom sediments was developed and constructed. In the result of theoretical researches the response functions have been calculated in the form of theoretical spectra of monitored radionuclides in definite measuring geometries. The results of mathematical modeling of the gamma-emitting transfer process allowed to estimate effective position of detection device for in situ measurements of specific activity radionuclides 2016 , vol. 7, no. 3, pp. 256-261 Zhukouski A. et al.

“…An important practical way to confirm the safe operation of nuclear power plants in the field of environmental protection is monitoring of radionuclide emissions into the atmosphere [2]. More than 90% of European NPPs included tritium and carbon-14 in the emissions monitoring program [3] due to the main contribution to the population dose of these radionuclides [4] (Fig. 1).…”

The production of electricity by European nuclear power plants with various types of reactor installations in the period from 1995 to 2017 was considered. For each nuclear power plant in Europe, the median specific emission indicators of tritium and carbon-14 (GBq/GWh) were calculated. Depending on these indexes, all stations were divided into 3 types: with the best, stable and the worst emission practices. A conservative estimate of the contribution of various reactor facilities to the activity of tritium and carbon-14 in the atmosphere was made. To assess the activity of tritium and carbon-14 entering the atmosphere as a result of emissions from the research nuclear reactor an experimental stand was developed.
