[en] The techniques are described of power generation with regard to their effectiveness which depends on the efficiency of the conversion of thermal energy into electric energy. The magnetohydrodynamic conversion of energy is based on the use of induced electromotive force which results from the movement of the conductor in the magnetic field. The use of liquid metal as the working medium makes it possible to increase the initial temperature of the magnetohydrodynamic cycle to the limit of the highest technically attainable temperatures. The total efficiency of energy conversion in magnetohydrodynamic converters is 2 to 6%. (J.B.)

[en] Full text: Now liquid metals find more and more wide application in reactor and chemical technologies, in metallurgy. Last years the opportunities of development of development breeders-reactors on fast neutrons with homogeneous fuel, as alternatives solid-fuels reactors are considered, hi offered reactors of such type the nuclear fuel circulates in an active zone or zone of reproduction as suspension, liquid melt or solution in the heat-carrier, which the liquid metal is. Optimum variant of working bodies of the appropriate installations are binary and multicomponent liquid-metal systems having a complex unique warmly and nuclear-physical properties. Naturally, experimental way of creation, and, then to measure of properties of composites - exactest, however it very expensive and labour-consuming. In this connection the important meaning gets forecasting properties unexplored systems. The authors of the given work have made attempt to generalize the data, available in the various references, on account thermal physical of the characteristics of liquid metals and to apply them to forecasting properties liquid-metal of alloys, as melts component of metal with nuclear weight average on all components of an alloy in view of their mass shares

[en] Thermal Hydraulics Aspects of Liquid Metal cooled Nuclear Reactors is a comprehensive collection of liquid metal thermal hydraulics research and development for nuclear liquid metal reactor applications. A deliverable of the SESAME H2020 project, this book is written by top European experts who discuss topics of note that are supplemented by an international contribution from U.S. partners within the framework of the NEAMS program under the U.S. DOE. This book is a convenient source for students, professionals and academics interested in liquid metal thermal hydraulics in nuclear applications. In addition, it will also help newcomers become familiar with current techniques and knowledge. (authors)

[en] This publication presents both an overview and detailed information on more than 150 experimental facilities being used for developing and deploying innovative liquid metal-cooled (sodium, lead and lead-bismuth) fast neutron systems, both critical and subcritical. Facilities, both under construction and those in operation are considered. It is expected that by providing the end users with detailed information on existing and future experimental facilities able to support innovative liquid metal cooled fast neutron systems, the publication will facilitate cooperation between organizations and knowledge transfer. An overview of the existing and future experimental facilities is presented in the body text of this publication. The profiles of all facilities in the form of individual papers are available on the attached CD-ROM and in the related on-line database maintained by the IAEA Catalogue of Facilities in Support of Liquid Metal-cooled Fast Neutron Systems (LMFNS Catalogue).

[en] The valve system is located axially movable in a housing and therein surrounded by a siphon (bellows). Before the siphon and between stem and housing is provided a slit. The siphon is surrounded by a heating coil, the slit may be cooled e.g. by cooling ribs provided in the outer wall of the slit. (P.K.)
