Generation III and III+ of nuclear reactors are most often operated in the world. Reactor safety issues are the most important part of designing nuclear power plants. This article presents the current accident protection systems in power plants. Among other things, the so-called "defense in depth" was presented, which minimizes the risk of the spread of nuclear fission products and the associated passive safety and reactor protection systems.

This paper focuses on the analysis of technical possibilities of a nuclear combined heat and power (NCHP) unit. The possibility of implementing a cogeneration unit in the cooperation with a typical PWR (Pressurized Water Reactor) is assessed by means of the numerical modelling of a process. The base for the model are operational parameters of Ascó Nuclear Power Station in Spain. The power plant employs a PWR reactor with more than 1000 MWe capacity. It is similar in size to a power plant which is planned to be built in Poland. Economic analysis of Tricity region have shown that the optimal amount of heat to be extracted is approximately 270 MWt. The investigated possibilities of heat extraction were the by-pass of a turbine, steam bleeding and partial removal of heat from the network of regenerating heat exchangers. Each of the methods has been assessed based on the criteria of electric power production drop, utilisation factor, weighted utilisation factor and interference with the base operational parameters. It was observed that the extraction of heat may lead to the increase of a power plant economy and fuel utilisation factor.

tom z. 54 [266]

47-52

Paper represents perspectives for wider usage of nuclear power as one of the alternative sources. Paper studies nuclear reactions and their general principles, classification of various radioactive isotopes and chain reactions. Here are given calculations of thermal power, radioactive products power, changes of neutron current in reactor and irregularity factor of neutron current. Power reactors are classified: by neutron energy that initiates decomposition reaction as thermal reactors and speed ones; by usage of fuel as multiply reactors and converters: by their structure as heterogeneous and homogeneous reactors; by cooling and moderating types as water, heavy water, water-graphite, gas, channel and complex reactors.

The article summarizes the main findings regarding a study on global problems, with an emphasis on global energy problems and possible solutions. To find solutions to global problems, the conditions of the new industrial revolution were taken into account, the features of technological development of economies in countries worldwide were investigated and, namely the essence of economic paradigms aimed at solving global problems was determined. Convergence of NBIC-technologies as a key factor of the new industrial revolution were characterized, and the process of converging knowledge, technologies and society as a mechanism for solving global problems was studied. Trends in the development of scientific and technical, innovative activities in Ukraine and countries worldwide were determined. In particular, the main directions for development of converging and advanced production technologies that are most promising for developed countries, developing countries and Ukraine are presented.
