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

Chemical reactions of caesium, tellurium and oxygen with fast breeder reactor cladding alloys Part VII — The kinetics of the corrosion of 12R72HV steel by Cs2Te at a constant 02 potential; comparison with rates for PE16 alloy

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

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

Chemical reactions of caesium, tellurium and oxygen with fast breeder reactor cladding alloys Part VI—The kinetics of the corrosion of PE16 alloy by Cs2Te at a constant O2 potential

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�

Chemical reactions of caesium, tellurium and oxygen with fast breeder reactor cladding alloys Part V — The corrosion of 12R72HV steel by Cs2Te under constant O2 potentials

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

Publikováno v: Journal of Nuclear Materials. 187:39-42

The depth and nature of the corrosion of 12R72HV steel by Cs2Te at 948 K after 168 h in sealed capsules has been determined. The depth of corrosion increases from 60 μm to ⩾ 140 μm on increasing the O2 potential from ΔGO2 = − 417 (Mo/MoO2 buff

Chemical reactions of caesium, tellurium and oxygen with fast breeder reactor cladding alloys

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

Publikováno v: Journal of Nuclear Materials. 172:304-313

The corrosion of the alloys PE16, M316 and FV448 by liquid Te in sealed capsules has been studied after 168 h at 948 K both with and without a buffer of Mo/MoO2. This buffer sets the thermodynamic oxygen potential at Δ G o 2 = −417 kJ mol −1 O 2

Publikováno v: Journal of Nuclear Materials. 172:206-219

The corrosion of the alloys PE16 and M316 by Cs : Te mixtures (1:1, 2:1 and 4:1) has been studied in sealed capsules under partial pressures of O2 set by metal/metal oxide couples at 948 K for 168 h. The alloys suffered severe intergranular corrosion

Publikováno v: Theriogenology. 34:1185-1193

Twenty-nine dairy heifers and 27 postpartum beef cows were utilized to determine if pregnancy rate following synchronization and artificially insemination (AI) was influenced by the presence of a functional corpus luteum (CL) prior to the induced est
