Sampling and characterization of sodium-water reaction products
Sodium-water reaction products (SWRP) which had accumulated in the bottom of the reaction products tank (RPT) of the Large Leak Test Rig (LLTR) were sampled and characterized. Analysis showed that the SWRP consisted of NaOH, Na/sub 2/O, NaH, and Na, as expected, in varying proportions. The unreacted sodium in the samples examined ranged from 32 to 60% by weight. The SWRP reacts (dissolves) rapidly and completely with ethanol, and somewhat less rapidly and completely with Dowanol PM. A magnetic, metallic residue was left, originating in the Croloy of the test article in the LLTR. These solvents should be investigated further as possible agents for cleaning sodium systems that are highly contaminated with water reaction products. The SWRP does not completely liquefy with heating to 800/sup 0/F (427/sup 0/C). Although it softens to a consistency similar to that of wet sand, it is unlikely that it would flow or could be pumped even at such elevated temperature. The presence of highly corrosive molten NaOH. (above 606/sup 0/F, 319/sup 0/C) also makes the hot draining of SWRP unattractive.

A fast large-area position-sensitive time-of-flight neutron detection system
A new position-sensitive time-of-flight neutron detection and histograming system has been developed for use at the Intense Pulsed Neutron Source. Spatial resolution of roughly 1 cm {times} 1 cm and time-of-flight resolution of {approximately}1 {mu}sec are combined in a detection system which can ultimately be expanded to cover several square meters of active detector area. This system is based on the use of arrays of cylindrical one-dimensional position-sensitive proportional counters, and is capable of collecting the x-y-t data and sorting them into histograms at time-averaged data rates up to {approximately}300,000 events/sec over the full detector area and with instantaneous data rates up to more than fifty times that. Numerous hardware features have been incorporated to facilitate initial tuning of the position encoding, absolute calibration of the encoded positions, and automatic testing for drifts. 7 refs., 11 figs., 1 tabs.

Research and Development Activities Fixation of Radioactive Residues Quarterly Progress Report, July-September 1961
Progress is reported on research and development work in pot calcination and radiant-heat spray calcination studies of synthetic Purex high-level wastes; and sorption studies using synthetic minerals and resins as well as natural minerals. The calcination studies are discussed in terms of batch calcination, melting of pot calcination products, spray calcination, and off-gas treatment; and sorption studies in terms of mineral reactions, fixation chemistry, and condensate wastes.

Mathematical modeling and economic analysis of membrane separation of hydrogen from gasifier synthesis gas
Investigators are studying hydrogen purification by membrane technology as a means to make the coal-to-hydrogen route economically attractive. To allow prediction of membrane performance and to facilitate comparisons between membrane and other technologies (cryogenic distillation, pressure swing adsorption), they developed a mathematical model to describe the permeation process inside a membrane module. The results of this model were compared with available experimental data (separation of CO{sub 2}/O{sub 2}/N{sub 2} mixtures). The model was first used to calculate the gas permeabilities from one set of mixed-gas experiments; the resulting permeabilities were then used to predict the results of the other mixed-gas experiments. The agreement between these predictions and the experimental data was good. However, model predictions using gas permeabilities obtained in pure gas experiments did not agree with the mixed gas experimental data. This disagreement is believed to be due to plasticization of the membrane by contact with CO{sub 2}. These results indicate that data obtained from experiments with mixed-gas feeds are necessary to adequately predict membrane performance when CO{sub 2} is present. The performance of different system configurations, including one and two stages of membrane modules, was examined. The different configurations examined were single module (SM), single module with recycle …
