The Aqueous Coordination Chemistry of Beryllium and its Relation to Fuel Processing - a Literature Survey

Description: A survey of the aqueous coordination chemistry of beryllium is given. The possible use of coordination chemistry in the separation of beryllium from fission products is discussed, outlining methods for separation processes.

The Irradiation Behaviour of Hot-Pressed Dispersions of (U, Th)Be13 in Beryllium :Second Irradiation Experiment

Description: Fuel specimens having uranium—thorium beryllides as the fissile bearing phase were irradiated at 400 to 700 ºC to burn—ups between 7 and 11a/0 uranium in a predominantly thermal flux, two specimens of massive (U;Th)Be13 exhibited good dimensional stability and low fission gas release. Dispersion specimens containing 20, 35, and 50v/o (U,Th)Be13 swelled by 3 to 18 per cent, and released up to 33 per cent, of the gaseous fission products. The results indicate that the mixed beryllide is an inhere… more

A Comparative Study of Two Grades of BeO

Description: Pechiney and Brush UOX BeO differ markedly in fabrication behaviour, only Brush UOX being readily sinterable. A comparative study of the two powders has shown few outstanding differences in powder properties. Both are of high purity but contain free and combined moisture to the extent of about 1.5 per cent. Pechiney BeO has a larger mean crystallite size (0.2 — 0.3μ) than Brush UOX (0.1 — 0.15μ) and a larger range of crystallite size, and both contain a small proportion of crystallites of size … more

Determination of the Stability Constants of Salicylato-Beryllium Complexes by a Distribution Method

Description: An investigation of the solvent extraction behavior of salicylato- beryllium complexes is reported. A simplified method for calculating the stability constants has been developed. The values obtained are beta /sub 1/ = 4.0 x 10/sup 12/ and beta /sub 2/ = 4 3 x 10/sup 22/ in 0.15 M sodium perchlorate. (auth)

Fuel Element Transient Temperature Studies

Description: A method is presented for the analysis of transient temperatures in a homogeneous circular cylindrical fuel element in a coolant channel with no axial conduction and no heat loss to the channel wall. In addition, some results were obtained for mean fuel element temperatures in power transients for a simpler model, but accounting for details of the axial coolant temperature distribution in the unsteady state.

Further Examination of H.T.G.C.R. Fuel Cycle Costs

Description: The equation for the H.T.G.C. reactor fuel costs developed previously in AAEC/TM141 has been modified and applied to "heterogenous" fuel systems. Fuel costs are reduced by 20-25 per cent in these systems relative to the "homogeneous" systems; these advantages arise from the longer life which may ben assumed for the unfueled beryllia and cheaper fabrication costs. The effects of reduced beryllia costs on fuel cycle costs are also examined.

Numerical Solutions of the Double P(sub)3 Equations in Slab Geometry

Description: The numerical solution of the double P/sub 3/ equations in slab geometry, by a forward-elimination back-substitution process, is described and is illustrated by application to a slab self shielding problem and by comparison with the results obtained by analytical solution of the equations.
