This study was undertaken to answer questions asked regarding the required rod stroke for control of modified Tory II-C reactors. All problems described were solved with the Angie code and based on Tory-II-C design problems, RZ 501 and RZ 502, representing hot and cold reactors respectively.

Abstract: Because of the outstanding heat transfer efficiency of sodium, it is necessary in sodium-cooled reactors to consider and attempt to prevent the occurrence of adverse stresses as a result of thermal transients in the system.

Abstract: A 3000 kw (thermal) bayonet duplex tube model steam generator was performance-tested in a liquid metal test loop at MSA Research Corporation, Callery, Pennsylvania, under the cognizance of Atomics International.

From introduction: This report is one of three volumes of the first annual progress report on the GE-NMPO high-temperature materials program conducted during calendar year 1961.

The diffusion of lithium in aluminum was measured at various temperatures with diffusion couples of aluminum-LiAl. The activation energy, E, is 33.3 kcal/mol, and the diffusion factor, Do, is 4.5 cm{sup2}/sec. (auth)

A model is proposed which depicts the sources of elutriatable fines in the fluidized bed calcination process as being in two major groups, spray drying mechanisms and attrition mechanisms. Based on this model, equations are derived which express the rate of change of the concentration of a chemical tracer material in the elutriated fines, following introduction of the tracer into the feed and following its removal from the feed. This system has been simulated on an analog computer, and by matching the computer simulation to results from an actual calciner run, the rates of generation of fines by each of the two groups of mechanisms has been determined; the same technique results in an estimate of the amount of these fines remaining in the fluidized bed. Agreement between postulated results and results of actual experimental tests lends credence to the usefulness of this analytical technique. (auth)

A survey and re-evaluation of previous work on polyurethane and polyurethane--epoxy copolymer systems was initiated to determine which phases are more productive than others. The effects of varying excess polyol content were studied. Work was carried out to define the amounts of butamediol that the system Adiprene L-213-ferric acetyl acetonate can tolerate and still be thoroughly cured. An experimental diallyl phthalate formulation was made and tested. A survey is being made of potential sources of kilogram quantities of Th/ sup 2//sup 3//sup 0/ in the United States. Analyses of various samples indicated concentrations almost three times as great as previously reported. The half-life of Rain was recalculated to include new data, and the results are reported as a function of the resolution time of the gas flow proportional counter. A method is being developed for determining the coincidence correction in porportional alpha counters by following the decay of a short-lived isotope. Additional determinations were made on the density of liquid cerium by the vacuum pycnometer method using tantalum pycnometers of about 0.5 cm/sup 3/ capacity. The viscosity of molten plutonium metal was investigated from 648 to 950 deg C with a cup viscometer. The construction of the hightemperature colorimeter was …

Isostatic-pressing techniques using reversible gels as the pressing medium were studied for improving the uniformity in density and structure of UC-- ZrC bodies. Control of powder-size fraction was studied as a means for controlling the pore distribution. Control of the carbon content by thermal treatment in a mixture of H/sub 2/ and hydrocarbon was also studied. Near stoichiometric 30 UC--70 ZrC powder was prepared by gas-metal reaction. Assembly of an apparatus for study of the thermochemical vapor-deposition of tungsten is near completion. The vaporization and fission product release rates of a hot- pressed high-density 30 UC -70 ZrC sample were measured from 1800 to 2000 deg C. A low-pressure gas adsorption apparatus was set up for measuring the true surface area of UC-ZrC samples. The cell used for the study of fission product diffusion through tungsten was fabricated. Samples are being prepared for fuel-clad compatibility and refractory-metal interdiffusion studies. Diffusion-emission studies were made on a rhenium-clad UC sample at 1800 deg C. The molybdenum pedestal of the loading device of a high-temperature mechanical testing furnace was modified. Thermionic emission microscopy showed that areas of high work function can co-exist with betteremitting UO/sub 2/ dispersions on the surface of a W-UO/sub …

The development of instruments for controlling reactor operation is reported. A shim-scram actuator was designed incorporating an electromagnetic dnlve for shim and scram, a shim speed limiting device, and a force feedback position indicator. A three-channel trip circuit and a two-out-of-three logic circuit using controlled switches in place of transistors was designed, built, and tested. A capacitance-type temperature sensor was operated in an inert atmosphere at temperatures up to 3782 deg F. Models of a gridded and a compensated a-c ionization chamber were tested in both thermal neutron and gamma environments. The compensated a-c ionization chamber demonstrated better than 98% gamma compensation at a thermalneutron flux of 5 x 10/sup -11/ nv and 1 Mw reactor power. Unpowered charged-fragment neutron detectors using boron-10 or uranium-235 as the emitter coating were demonstrated to respond linearly to changes of thermalneutron flux. Potentials, developed within the detecting circuit, possibly due to contact potentials, are suspected to be the cause of detector output-current instability as a function of time. Fission counter operation at 816 deg C was demonstrated to be feasible, but operation was not entirely satisfactory. Adequate reactor power range neutron sensing to 535 deg C is feasible using uncompensated d-c ionization chambers. …

Generalized computer codes were devised for solving stress problems of some complexity. These codes were applied to stress problsms relating to the graphite moderator elements in the Experimental Gas-cooled Reactor. The stress relief obtained by aubdividing the moderator elements was evaluated. The distontion and bending moments of the elements were also determined. (auth)
