[en] In this article availability information contained within the Centralized Reliability Data Organization (CREDO) liquid-metal reactor (LMR) data base is presented, and the availability critical items lists are developed. Individual components are ranked in prioritized lists from worst to best performers from an availability standpoint. Availability, as used here, is assumed to be an inherent characteristic of the component and is not necessarily assumed to be related to plant operability

[en] The roof slab has a metallic annular envelope made of two shell rings and two plates filled with concrete. Cylindrical spaces are provided in the slab for the passage of the reactor components. A truncated shell ring is welded to the metallic envelope and constitutes the reinforcement element of this envelope. One shell ring separates the inner volume of the envelope in two parts; it is design with apertures to allow the passage of the reactor components. The invention can be applied more particularly to fast reactors cooled by liquid sodium

[en] The reactor concepts addressed in this section are the SSTAR and STAR-LM small lead cooled reactors without on-site refuelling, developed in the Argonne National Laboratory and other national laboratories of the USA. Detailed descriptions of these concepts are presented; short summaries of the concepts are given. The inherent safety features and passive safety design options of the STAR-LM are similar to those of the SSTAR. Because it would be redundant to list them, they are not reproduced below; the reader is referred to the sections on SSTAR

[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] This invention relates to a non-destructive testing apparatus and, in particular, to a vehicle that can be moved at will, for transporting instruments for testing against a surface remote from the operator. Under this invention a vehicle is intended, for instance, for testing the vessel of an installation containing a liquid metal cooled nuclear reactor of the pond type. Such an installation includes a nuclear reactor comprising an assembly containing a nuclear fuel immersed in a pond of liquid metal coolant, located in a vessel which is itself placed in a concrete containment vessel
