Description
The research of new nuclear reactors is gaining urgent importance worldwide due to the need for continuous improvement of technologies to ensure safety, efficiency, and emissions reduction. This is crucial in the context of climate change and rapid technological development, which demand constant updating and improvement of nuclear energy. The objective of the study was to analyse next-generation reactors worldwide and identify their advantages and potential prospects for the future. The research utilized statistical, comparative, and analytical methods. The results of the analysis considered contemporary technological and safety parameters related to the operation of such reactors, including their ability to optimize fuel usage, enhance operational safety, and effectively manage radioactive waste. As a result of the study, fourth-generation nuclear reactors were analysed, including fast neutron reactors using gas cooling, very high-temperature reactors, reactors using sodium as a coolant, fast neutron reactors with lead cooling, reactors where the reaction occurs in molten salt, and supercritical water-cooled reactors. Each of these reactors has its unique features that make them distinctive in their application. For example, gas-cooled reactors have high productivity due to their ability to achieve high temperatures without significant pressure. On the other hand, molten salt reactors offer flexibility in using different types of fuel, including spent fuel, and can help reduce the level of radioactive waste through the use of special materials. During the analysis, it was noted that fourth-generation reactors, using various cooling and reaction-slowing technologies, are characterized by high efficiency, low accident risk, and the ability to produce stable electricity. Improved methods of reaction control open up new possibilities for the efficient production of electricity and increased safety in nuclear energy. The practical significance of the research lies in the opportunity to enhance modern electricity production technologies and ensure greater safety and efficiency in the field of nuclear energy
