Chemical reactions of Zircaloy-4 and zirconium with (i) dicaesium telluride, Cs2Te, (ii) caesium tellurite, Cs2TeO3, and (iii) tellurium, under different oxygen potentials

Autor: Richard J. Pulham, M.W. Richards, D.R. Kennard

Publikováno v: Journal of Nuclear Materials. 223:277-285

Although Zircaloy-4 and Zr foil are inert to solid Cs2Te at 948 K, reaction occurred when O2 was admitted from buffers in sealed systems over 168 h. The products consisted of a zirconium telluride (or caesium zirconium telluride) sandwiched between t

Publikováno v: Journal of Nuclear Materials. 223:180-185

The rates of reaction of the alloy 12R72HV (essentially 65.9% Fe, 15.3% Cr and 14.8% NO with Cs2Te under a constant O2 potential set by a Ni/NiO couple have been measured from 898 to 983 K. An electrical resistance method was used to determine the re

Chemical reactions of dicaesium telluride, Cs2Te, and of dicaesium telluride/caesium mixtures with zirconium and with Zircaloy-4

Autor: M.W. Richards, Richard J. Pulham

Publikováno v: Journal of Nuclear Materials. 218:143-150

Zircaloy-4 foils, zirconium foils and zirconium powder have been immersed in molten dicaesium telluride Cs 2 Te (m.p. 1094 ± 3 K) at 1123 K, in the telluride plus liquid caesium at 1023 K, and in the solid compound Cs 2 Te at 1023 K. The components

Solutions of aluminum in liquid lithium: contribution to the Li-Al phase diagram

Autor: Peter Hubberstey, P. Hemptenmacher, Richard J. Pulham

Publikováno v: Journal of Phase Equilibria. 15:587-590

The Li-rich (up to 15.8 at.% Al) region of the Li-Al phase diagram has been determined by resistivity-temperature and thermal analytical methods. The eutectic lies at 180.5 ± 0.4 °C (453 ± 0.4 K) and 0.57 ± 0.04 at.% Al. The hypereutectic liquidu

The effect of gaseous CsTe mixtures on nickel

Autor: Richard J. Pulham, Martyn W. Richards

Publikováno v: Journal of Nuclear Materials. 210:30-33

Nickel capsules which were used to contain Cs-Te mixtures with Cs:Te ratios of 1:1, at 948 K for 168 h during corrosion tests on Fast Nuclear Reactor fuel cladding materials were themselves severely embrittled by the vapour of the liquid mixtures. Th

Autor: Richard J. Pulham, M.W. Richards

Publikováno v: Journal of Nuclear Materials. 209:122-127

The rates of reaction of the alloy PE16 with Cs2Te under a constant O2 potential set by a Ni/NiO couple have been measured from 873 to 1038 K. An electrical resistance method was used to determine the resistivity of the alloy which is given by ρ μ�
