Constitutional studies on carbide nuclear fuels for fast breeder reactors: I. The uranium-yttrium-carbon ternary system

The ternary system U-Y-C has been investigated at 1400°C using X-ray, electron probe microanalysis and reflected light microscopy. Arc-melted and annealed alloys of various compositions were examined and the major phase fields established. Extensive solid solubility occurs within the system and the solubility limits are reported.     

Compatible Extended Use of the CAMAC Dataway

A study Group of the ESONE Cmmittee has prepared proposals for extensions to the CAMAC Dataway. These extensions allow modules and controllers to exploit microprocessor technology by providing a greatly extended addressing range, logical addressing and handshake timing in a manner that is compatible with existing CAMAC equipment. This paper describes the specifications that have been prepared by the COMPEX Study Group and relates the potential application areas to those of "standard" CAMAC.     

Constitutional studies on carbide nuclear fuels for fast breeder reactors: III. The uranium-barium-carbon ternary system at 1400°C,with observations on the uranium-strontium-carbon system

The ternary system U-Ba-C has been examined at 1400°C and the solid-state compatibility lines established. No compound formation was found to occur and solubility effects were found to be minimal. A tentative examination of compositions in the U-Sr-C system indicates that it is of a similar form to that of the U-Ba-C system.     

Constitutional studies on carbide nuclear fuels for fast breeder reactors: II. The uranium-praseodymium-carbon ternary system

Investigations have been carried out at 1400°C on the ternary system U-Pr-C and the major phase fields have been established. A considerable degree of solid solubility was found and the limits established are reported.
