“…1) consists of a plasma source of D-T neutrons and a blanket part. The blanket part is based on the concept of the core of a multi-purpose high-temperature gas-cooled reactor facility of low power (Shamanin et al 2015, Bedenko et al 2019a) with a near-axial region modified for the plasma neutron source (Arzhannikov et al 2016). The modified core (Yurov et al 2016, Bedenko et al 2021b) is a blanket composed of prismatic graphite fuel and non-fuel blocks containing dispersed ( weapons-grade(wg) Pu-Th)O 2 -fuel in cylindrical channels (Bedenko et al 2019a).…”

The PNS is a plasma vacuum chamber with a linear configuration (Anikeev et al 2015, Yurov et al 2016, in which the high-temperature plasma is contained by a magnetic field.…”

“…The ongoing research (Arzhannikov et al 2016, 2019, Prikhodko and Arzhannikov 2020, Bedenko et al 2021a) is aimed at the development of small generation and has the prospect of entering the field of energy use in a shorter period. The facility under study is a hybrid reactor, the core (blanket) of which consists of an assembly of prismatic graphite blocks (Shamanin et al 2015, Bedenko et al 2019a) and an extended plasma source of additional D-T-neutrons of a linear configuration (Anikeev et al 2015, Yurov et al 2016.…”

The current state of research in the field of nuclear and thermonuclear power aimed at creating power generation plants makes it possible to predict the further development of modern power industry in the direction hybrid reactor power plants. Such hybrid systems include a tokamak with reactor technologies, worked out in detail in Russia, and systems with an additional source of neutrons. Power generation plants using tokamaks and accelerators with the required level of proton energy will be of exceptionally large size and power, which will postpone their construction on an industrial scale to the distant future. The ongoing research is aimed at the development of small generation and has the prospect of entering the field of energy use in a shorter period. The hybrid reactor facility under study consists of an axisymmetric assembly of fuel blocks of a high-temperature gas-cooled reactor and a linear plasma source of additional neutrons. The paper demonstrates the results of optimization plasma-physical, thermophysical and gas-dynamic studies, the purpose of which is to level the distortions of the power density field, which are formed in the volume of the multiplicating part of the facility due to the pulsed operation of the plasma source of D-T-neutrons. The studies on increasing the “brightness” of the source and modeling its operating modes were carried out using the DOL and PRIZMA programs. The thermophysical optimization and gas-dynamic calculations were performed using the verified SERPENT and FloEFD software codes. The calculations were made on a high-performance cluster of the Tomsk Polytechnic University.

“…As, Gao, Nam, Jang, and Ko (2019) stated that Gen IV technology nuclear reac-tors are cost-effective reactors which provides nuclear fuel cycle and uranium utilization. Bedenko, Ghal-Eh, Lutsik, and Shamanin (2019) tested that Gen IV technology reactors are economical with thorium-plutonium nuclear fuel cycle and computational developments will solve nuclear power engineering. Also, Belokrylov, Bol'shukhin, Komissarov, Petrunin, and Poverennov (2020) denoted that computational system will provide fast business process and outcome from nuclear reactor.…”

Nuclear energy investments are important for the social and economic development of countries. Thanks to these investments, no carbon gas is released into the atmosphere while providing energy. This situation prevents the environmental pollution problem. On the other hand, nuclear energy contributes to countries to obtain uninterrupted electricity. However, the installation of nuclear power plants is now difficult. A serious technological infrastructure is required to build these facilities. This situation is especially important for countries that do not yet have nuclear power plants. In order to increase the use of nuclear energy in these countries, support from nuclear energy companies is required. However, nuclear energy investors may not want to invest in every country. In this study, the factors that affect the investment decisions of nuclear energy investors are analyzed. In this framework, a detailed literature analysis was performed, and 4 different criteria were determined. An analysis was carried out using the Entropy method to determine the most important factor among these factors. According to the results of the analysis, it is determined that the socio-political factors in the country have the most importance in the decisions of nuclear energy investors. Considering these issues, it is understood that countries should pay attention to public acceptance to attract the attention of nuclear energy investors.

“…Nuclear isotopes, distinguished by their unique neutron numbers, play a pivotal role in various sectors [ 1 ], including medicine [ 2 , 3 ], energy [ 4 , 5 ], and environmental studies [ 6 ]. Their distinct characteristics, such as radioactivity and half-life, render them invaluable in a range of applications from diagnostic procedures [ 7 ] and therapeutic interventions [ 8 ], to serving as a clean energy source [ 9 ].…”
