3-D transient eddy current calculations for the FELIX cylinder experiments
The three-dimensional eddy current transient field problem is formulated first using the U-V method. This method breaks the vector Helmholtz equation into two scalar Helmholtz equations. Null field integral equations and the appropriate boundary conditions are used to set up an identification matrix which is independent of null field point locations. Embedded in the identification matrix are the unknown eigenvalues of the problem representing its impulse response in time. These eigenvalues are found by equating the determinant of the identification matrix to zero. When this initial forcing function is Fourier decomposed into its spatial harmonics, each Fourier component can be associated with a unique eigenvalue by this technique. The true transient solution comes through a convolution of the impulse response so obtained with the particular external field decay governing the problem at hand. The technique is applied to the FELIX cylinder experiments; computed results are compared to data. A pseudoanalytic confirmation of the eigenvalues so obtained is formulated to validate the procedure.

Aerosols generated by spills of viscous solutions and slurries
Safety assessments and environmental impact statements for nuclear fuel cycle facilities require an estimate of potential airborne releases caused by accidents. Aerosols generated by accidents are being investigated by Pacific Northwest Laboratory to develop methods for estimating source terms from these accidents. Experiments were run by spilling viscous solutions and slurries to determine the mass and particle-size distribution of the material made airborne. In all cases, 1 L of solution was spilled from a height of 3 m. Aqueous solutions of sucrose (0 to 56%) gave a range of viscosities from 1.3 to 46 cp. The percent of spill mass made airborne from the spills of these solutions ranged from 0.001 to 0.0001. The mass of particles made airborne decreased as solution viscosity increased. Slurry loading ranged from 25 to 51% total solids. The maximum source airborne (0.0046 wt %) occurred with the slurry that had the lightest loading of soluble solids. The viscosity of the carrying solution also had an impact on the source term from spilling slurries. The effect of surface tension on the source term was examined in two experiments. Surface tension was halved in these spills by adding a surfactant. The maximum weight percent airborne from …

Analyses of operational times and technical aspects of the Salton Sea scientific drilling project: (Final report)
The Deep Salton Sea Scientific Drilling Program (DSSSDP) was conducted in Imperial County of California at the Southeastern edge of the Salton Sea. Emphasis was on the acquisition of scientific data for the evaluation of the geological environment encountered during the drilling of the well. The scientific data acquisition activities consisted of coring, running of numerous downhole logs and tools in support of defining the geologic environment and conducting two full scale flow tests primarily to obtain pristine fluid samples. In addition, drill cuttings, gases and drilling fluid chemistry measurements were obtained from the drilling fluid returns concurrent with drilling and coring operations. The well was drilled to 10,564 feet. This report describes the field portions of the project and presents an analysis of the time spent on the various activities associated with the normal drilling operations, scientific data gathering operations and the three major downhole problem activities - lost circulation, directional control and fishing.

Animal mortality resulting from uniform exposures to photon radiations: Calculated LD/sub 50/s and a compilation of experimental data
Studies conducted during the 1950s and 1960s of radiation-induced mortality to diverse animal species under various exposure protocols were compiled into a mortality data base. Some 24 variables were extracted and recomputed from each of the published studies, which were collected from a variety of available sources, primarily journal articles. Two features of this compilation effort are (1) an attempt to give an estimate of the uniform dose received by the bone marrow in each treatment so that interspecies differences due to body size were minimized and (2) a recomputation of the LD/sub 50/ where sufficient experimental data are available. Exposure rates varied in magnitude from about 10/sup -2/ to 10/sup 3/ R/min. This report describes the data base, the sources of data, and the data-handling techniques; presents a bibliography of studies compiled; and tabulates data from each study. 103 refs., 44 tabs.

Annealing of cold worked hypostoichiometric Ni/sub 3/Al alloys using positron lifetime spectroscopy
Hypostoichiometric Ni/sub 3/Al alloys of composition 76.2 Ni:23.8 Al containing impurity levels of boron and hafnium were either cold rolled or pressed. Rolled and pressed samples were deformed by 20% and 10% thickness reductions, respectively. Samples were annealed isochronally at approximately 50/sup 0/C intervals up to 1050/sup 0/C. Two major annealing stages were apparent in all three alloys studied. These could be attributed to vacancy migration to sinks and annealing of dislocations and(or) recrystallization. The onset of vacancy migration occurred at approximately 200/sup 0/C in all three alloys. Annealing of dislocations started at 650/sup 0/C to 700/sup 0/C and was complete at 1000/sup 0/C for alloys which contained boron and or hafnium impurities. In the pure alloy the onset of dislocation annealing occurred at 800/sup 0/C and was incomplete at the highest (1050/sup 0/C) annealing temperatures reached.

Assessment of ceramic composites for multimegawatt space nuclear power systems
A calculational thermodynamic equilibrium analysis of the compatibility of ceramic-ceramic composites and a nonequilibrium assessment based on the literature of their use in proposed multimegawatt space nuclear power systems was performed. The five candidate composites included Al/sub 2/O/sub 3/-reinforced Al/sub 2/O/sub 3/, SiC-whisker-toughened Al/sub 2/O/sub 3/, SiC-whisker-toughened Si/sub 3/N/sub 4/, SiC-fiber-reinforced ZrC, and carbon-fiber-reinforced ZrC. The reactor concepts included Brayton cycle (continuous and burst mode) and Rankine cycle. It was determined that Al/sub 2/O/sub 3/-reinforced Al/sub 2/O/sub 3/ and carbon-fiber-reinforced ZrC are compatible in the Brayton-cycle continuous-mode system and that Al/sub 2/O/sub 3/-reinforced Al/sub 2/O/sub 3/, SiC-fiber-reinforced ZrC, and carbon-fiber-reinforced ZrC are compatible in the Rankine-cycle system. None of the candidate ceramic composite systems was likely to be sufficiently stable under Brayton-cycle burst-mode conditions.

Calculation of fast-neutron induced-fission multiplication in large PuO/sub 2/ samples
Fast-neutron multiplication in large PuO/sub 2/ samples has been studied using both Monte Carlo computer codes and the coincidence correlation equations developed by K. Boehnel and N. Ensslin. Samples covering the mass range from 0.1 to 7.2 kg of plutonium have been measured and the multiplication results were compared with the theoretical predictions. The results are in agreement within the uncertainties in the sample characteristics. A parametric study was performed to determine the effect of sample density and moisture variation on the neutron multiplication.

Castor-1C spent fuel storage cask decay heat, heat transfer, and shielding analyses
This report documents the decay heat, heat transfer, and shielding analyses of the Gesellschaft fuer Nuklear Services (GNS) CASTOR-1C cask used in a spent fuel storage demonstration performed at Preussen Elektra's Wurgassen nuclear power plant. The demonstration was performed between March 1982 and January 1984, and resulted in cask and fuel temperature data and cask exterior surface gamma-ray and neutron radiation dose rate measurements. The purpose of the analyses reported here was to evaluate decay heat, heat transfer, and shielding computer codes. The analyses consisted of (1) performing pre-look predictions (predictions performed before the analysts were provided the test data), (2) comparing ORIGEN2 (decay heat), COBRA-SFS and HYDRA (heat transfer), and QAD and DOT (shielding) results to data, and (3) performing post-test analyses if appropriate. Even though two heat transfer codes were used to predict CASTOR-1C cask test data, no attempt was made to compare the two codes. The codes are being evaluated with other test data (single-assembly data and other cask data), and to compare the codes based on one set of data may be premature and lead to erroneous conclusions.
