High-Temperature Nuclear Reactors (Overview. Part 1) / Augstas Temperatūras Kodolreaktori (Pārskata raksts) 1. daļa

At the Generation IV International Forum (GIF) of 2001 the measures were approved which are necessary for the development of future generation nuclear reactors (NRs). Six best high-temperature NR technologies were selected, with the main criteria being the safe and economically profitable operation, long-term use, protection against the employment of nuclear material for military purposes and terroristic attacks as well as technologies of fuel close cycle in order to increase the amount of fission material and decrease the amount of highly radioactive waste. In four of the technologies, apart from electricity production also hydrogen is obtained. Part 1 presents a generalized description of the high-temperature NRs, their comparative characteristics and history, with the stopped and operational HTNRs outlined. The properties of different type nuclear fuels are described in detail
