Near stoichiometric bulk polycrystalline CdSiAs/sub 2/ has been synthesized by two techniques: (1) direct fusion of the elements and (2) direct fusion of the binaries SiAs, Cd/sub 3/As/sub 2/ and CdAs/sub 2/. The latter technique resulted in denser ternary material with good homogeneity. The above binaries melt congruently and were also formed by direct fusion. Sputtered ternary films were formed using a bulk CdSiAs/sub 2/ target, and a composite target of CdAs/sub 2/ discs in a Si plate. Composition of the CdSiAS/sub 2/ target changed with sputtering time. Amorphous films deposited from that target were heat treated, and became crystalline and near stoichiometric but with poor mechanical properties. It appears that films deposited from the composite target (Si + CdAs/sub 2/) can be adjusted to stoichiometry by means of sputtering power and target geometry. As deposited, these films also were amorphous. With respect to evaporated films, the study of thermal decomposition of CdSiAs/sub 2/ in vacuum was completed. The decomposition is preferential toward Cd between 570/sup 0/ and 710/sup 0/C, and toward As in the 710 to 1010/sup 0/C range. It is concluded that evaporation of the ternary is not a suitable method for forming CdSiAs/sub 2/ films. Plans for …

In March 1979, ETEC published as ETEC-TDR-78-19 a search which updated earlier NRC studies of saturated or subcooled water flow through relief valves, under ATWS conditions. This Supplement expands upon that search to include supercritical steam-water flow. No applicable data for the supercritical conditions was found, nor were any newer data on saturated or subcooled conditions uncovered. The Supplement also updated a look for facilities currently capable of simultaneously imposing all ATWS conditions upon test relief valves. Results confirmed the negative findings of ETEC-TDR-78.19.

In designing a plutonium-uranium core with thorium internal blankets there are several parameters that must be investigated to identify the design with the best performance. Choices include: the amount of moderation in the blanket, whether moderation is incorporated from the outset or added after an assembly is shuffled to the external blanket, and the cycle length both for the core and internal blanket assemblies. To investigate the effect of these parameters several core and blanket burnup analyses were performed.
