This report talks about Calculations of Flow Oscillations During Reflood Using Relap4/MOD6

The known electronic configurations of simple elements in Laves compounds are correlated with those of the more complex systems to determine their electronic configurations and gaseous state promotion energies.

Exploratory hot-cell tests were made to determine the amounts of fission products released by high-temperature oxidation (voloxidation) of irradiated fuel, initially (Th/sub 0/ /sub 96/U/sub 0/ /sub 04/)O/sub 2/, and whether the treatment would affect the subsequent dissolution of the oxide. Fifteen-year-decayed fuel rods were sheared to dislodge the (Th,U)O/sub 2/ from its cladding, sieved to determine the size range, and an aliquot was oxidized in flowing air at 600/sup 0/C for approx. 2 h while tumbling at 12 rpm. The voloxidation released only 0.2% of the /sup 85/Kr and 6% of the /sup 3/H contained in the (Th,U)O/sub 2/. The oxidized and unoxidized portions were leached three times in a 95/sup 0/C Thorex reagent to dissolve the fuel. The voloxidation apparently had no effect on the dissolution of the mixed oxide. The presence of cladding slowed the dissolution by limiting the amount of fuel exposed to the acid.

A subcode (FVAPRS) is described which calculates fuel vapor pressure. This subcode was developed as part of the fuel rod behavior modeling task performed at EG and G Idaho, Inc. The fuel vapor pressure subcode (FVAPRS), is presented and a discussion of literature data, steady state and transient fuel vapor pressure equations and estimates of the standard error of estimate to be expected with the FVAPRS subcode are included.

This report summarizes the research and development on 0.5-mm-diameter, compacted, metal sheathed thermocouples. The objectives of this research effort have been: to identify and analyze the sources of temperature measurement errors in the use of 0.5-mm-diameter sheathed thermocouples to measure the surface temperature of the cladding of fuel-rod simulators in the Core Flow Test Loop (CFTL) at ORNL; to devise methods for reducing or correcting for these temperature measurement errors; to estimate the overall temperature measurement uncertainties; and to recommend modifications in the manufacture, installation, or materials used to minimize temperature measurement uncertainties in the CFTL experiments.

The determination of the change in chemical composition of the diluted drill fluid and its separation from the chemical background contributed by the drill fluid, drill mud, and other aquifer leakage is the essence of the chemical log. Samples of the drill fluid were collected for chemical analysis at certain times during the drilling operations. The chemical logging study of the geothermal wells is described. (MHR)

The heat capacity, C/sub p/ (T = 298-1000 K), and the thermal diffusivity, ..cap alpha..(T = 623-773 K), of ScD/sub x/ and ErD/sub x/ (x = 0-1.83) have been measured. C/sub p/ of ScD/sub x/ increases with x for x = 0-1.59 over the entire temperature range, but then declines for x = 1.83. ErD/sub x/ shows a monotonic increase of C/sub p/ with x, and exhibits a sharp positive anomaly at 910 K for x = 1.82. Both materials display an excess heat capacity which is attributed to disorder in the deuterium sublattice. A minimum in ..cap alpha.. is observed for ScD/sub x/ and ErD/sub x/ at mid-range values of x where disorder is greatest; ..cap alpha.. for all samples is fairly constant with T in this limited temperature range.

This report is a combination of monthly progress reports submitted by AiResearch Manufacturing Company. It contains a summary of activities and progress made from November 1, 1978, to February 28, 1979. AiResearch Manufacturing Company is developing prototype solar heating/cooling systems under NASA Contract NAS8-32091. This effort calls for the development, manufacture, test, system installation, maintenance, problem resolution, and performance evaluation.

Two existing hydrotreating units were redesigned to increase their operating range, and the necessary parts ordered. A new microactivity testing (MAT) unit was designed, and the parts ordered. Base-line testing procedures were improved, and the effect of unit parameters on catalytic activity was studied with borrowed Filtrol testing units. Synthesis and characterization of various catalytic components and matrix modifications was carried out. Sodium-Y zeolites with different silica-alumina ratios and different crystal sizes are being synthesized. Synthetic montmorillonite micas (SMM) in the ammonium (SMM-NH/sub 4/) form have been prepared with silica-alumina ratios from 2.16 to 2.58, and cation exchanged with Co and Ni. Lattice-substituted SMM (SMM-M) have been prepared on a laboratory scale with Ni/sup 2 +/, Co/sup 2 +/, and Fe/sup 3 +/ substituted for Al/sup 3 +/ in the octahedral coordination position. A series of relatively large pore size alumina supports with varying pore size distributions, and good strengths, have been prepared. These alumina supports have been made into hydrotreating catalysts by impregnation with different concentrations of CoO/MoO/sub 3/ and NiO/MoO/sub 3/.

This package contains information that is intended to be a guide for installation, operation, and maintenance of the various Solaron Solar Subsystems. The subsystems consist of the following: collectors, storage, transport (air handler) and controller for heat pump and off-peak storage. Two prototype residential systems have been installed at Akron, Ohio, and Duffield, Virginia.

The applicability of madern signal processing techniques to the safeguards problem for a plutonium nitrate storage tank and concentrator is addressed. The techniques involve mathematical modeling, optimal estimation of process variables, and the detection of abnormal changes in these variables due to adversary diversion. The performance of these techniques is preesented for various diversion scenarios.

Most of the wood pulp in the U.S. is produced by cooking, or digesting, wood chips in a chemical solution. These pulping processes have effluent streams which contain dissolved lignins, lignin breakdown products, and carbohydrates. There is a substantial economic incentive to use these materials as feedstocks for the production of high-valued micellar flood chemicals. The pulp and paper industries have practiced chemical recovery for almost a century. The largest chemical recycle processes are the internal recycle of inorganic salts for reuse in pulping. This is coupled with the use of waste organic compounds in the liquor as a fuel for directly-fired evaporation processes. Diversion of effluent and low valued streams for chemical recovery using fermentation, purification, or synthesis methods appears technically feasible in several cases. The use of new recovery processes could yield a variety of different wood-effluent based products. Some of the sugar acids in pulping liquors might be used as sequestering agents in reservoirs where there are large amounts of multivalent cations in flood brines. Fermentation production of high viscosity polymers, sequestering agents, and coagent alcohols appears worth further investigation. Tall oil acids and their derivatives can be used as surfactants in some reservoirs. Some waste constituents …

The analysis used the TRUMP computer code to evaluate the thermal fields for six repository scenarios that studied the effects of room ventilation, room backfill, and repository thermal diffusivity. The results for selected nodes are presented as plots showing the effect of temperature as a function of time. 15 figures, 6 tables.

Ballooning modes are found to possess a second stable regime for high beta. The range of unstable beta values depends on the details of the equilibrium, and in particular, on shear, which can be strongly stabilizing.
