Modeling of radionuclide movement in the groundwater system beneath the Hanford Reservation requires mathematical simulation of the two-dimensional flow in the unconfined aquifer. This was accomplished using the nonlinear, transient Boussinesq equation with appropriate initial and boundary conditions, including measured Columbia River stages and rates of wastewater disposal to the ground. The heterogeneous permeability (hydraulic conductivity) distribution was derived by solution of the Boussinesq equation along instantaneous streamtubes of flow employing a measured water table surface and a limited number of field-measured hydraulic conductivity values. Use of a successive line over-relaxation technique with unequal time steps resulted in a more rapid convergence of the numerical solution than with previous techniques. The model was used to simulate the water table changes for the period 1968 through 1973 using known inputs and boundary conditions. A comparison of calculated and measured water table elevations was made at specific well locations and the quality of the verification simulation was evaluated using a data retrieval and display system. Agreement between the model results and measured data was good over two-thirds of the Hanford Reservation. The capability of the model to simulate flow with time-varying boundary conditions, complex boundary shapes, and a heterogeneous distribution of aquifer …

Experimental studies in which the perturbations of gamma-ray angular correlations were used to observe and measure the interactions of nuclear moments with chemically generated electric field gradients are reported. Such quadrupole interactions can provide detailed information on molecular structure and chemical bonding. Experiments were completed with /sup 181/Hf binding to Vitamin B/sub 12/ and /sup 181/Hf and /sup 111/Ag probes in DNA, as well as /sup 181/Hf studies of several inorganic compounds containing Hf--oxygen and Hf--phosphate bonds. Experimental research programs in heavy-ion nuclear reactions studies were initiated at several major accelerator facilities. The energetic fragments from heavy-ion transfer reactions on medium mass targets were investigated by using a counter telescope with element and mass resolution. Some results from /sup 65/CU + /sup 12/C at 130 MeV are presented. The emissions of H and He in hard grazing collisions of /sup 86/Kr with /sup 197/Au are being measured at the SuperHILAC. In this experiment, both singles measurements of the light charged particles and coincidence observations with deep inelastic processes are in progress. In a related, but distinct, experiment the fusion, fission, and charged-particle-emission probabilities for /sup 194/Hg compound nuclei excited to 97.5 MeV by different reactions using matched heavy-ion beams are …

A new approach for the solution of the Vlasov equation for complex magnetic field geometries has been developed using operator techniques. The general approach is illustrated by determining the perturbed distribution function and density operator for the problem of shear stabilization of drift waves for transverse and arbitrary directions of propagation. The ensuing corrections to stability criteria of current theories are obtained for certain domains of physical parameters. Preliminary work on the integral equation approach to the dispersion relation has been initiated. As a prelude to the study of particle orbits in complex mirror geometries, the adiabatic and non-adiabatic behavior of a harmonic oscillator has been studied using operator methods. High-..beta.., high shear plasma sheath configurations have been studied with the full ion dynamics taken into account and electrons treated in the zero and first order approximation, in the ratio of the electron Larmor radius to the scale length. The resulting sheath structure equation in the lowest order approximation has been solved for certain entering ion distributions, and prepared for computer analysis for others. In this approximation the electron current parallel to magnetic field lines has to be assumed suppressed or predetermined. Equations in the next order approximation include the …

In a nuclear reactor, tubes are pressurized from interior by coolant, while externally no pressure is applied on them. The pressure that causes any of the tubes to burst is random and has certain distribution. By using the presently available data from stress-strain experiment, mathematical procedure for finding the distribution form of the ultimate stress is made and is justified theoretically and empirically. The distribution function obtained is important in analyzing the problem of loss of coolant in the reactor.

A third successful well in Raft River was completed, to 6000 ft, striking a 149/sup 0/C (300/sup 0/F) reservoir, at less cost than either of the other two wells, despite being drilled in a formation of lower productivity. This well employed a special multiple channel drilling technique, which in retrospect was necessary to make the well useful for production of fluids. Two successful wells of shallow depth (1200 ft) were also finished in Boise this summer, both producing artesian flows of the predicted temperature, 75/sup 0/C (167/sup 0/F). The sources in tapping both the Raft River and Boise geothermal reservoirs was followed by an extensive reservoir monitoring program. By-product uses of the Raft River geothermal water received season long testing for irrigation of crops and for fish culture. Both results were highly encouraging. In Boise, the success of the two shallow wells and some design innovations lead to the conclusion that providing geothermal space heat to the capitol and other state-owned buildings could be a major economic success if double or triple the number of buildings could be served.

Continued fundamental studies are proposed on both the formation and properties of new materials for high-energy, gas-phase lasers. As originally proposed, attention will be focused mainly (but not wholly) on systems which have bound excited states but unbound ground states. An important class of such excimer/exciplex systems has a van der Waals dimer/oligomer as its ground state. In the original proposal for this work, a new method for the preparation of excimers and exciplexes was presented in which van der Waals complexes are formed as intermediates. Systems under study include the excited states of dimers, oxides and halides of inert gases.

This study compared TIE's and TIR's to determine if any important differences exist between them. Salaries, performance ratings, supervisors' opinions, schools, and amount of time to advance from one PEP level to another were compared for the TIE's and TIR's. No statistically significant differences were found. The TIE program provides an important opportunity for members of minority groups and females to move into ESA/SAT level work. 6 figures, 13 tables.

A summary is presented of studies of the heat transfer and pressure drop characteristics of extended surfaces. The summary is based on data that were compiled and analyzed with the objectives of determining the effects of geometrical configurations of an extended surface tube bank on its heat transfer and pressure drop characteristics. A generalized correlation of heat transfer and friction losses was developed on the basis of this analysis. These correlations can be used to predict the performance of an extended surface tube bank of specified geometry and flow conditions.

It is concluded that the direct effects of an ideal form of fusion technologies would be socially more desirable than those of the alternatives. This is particularly true of the second generation fusion power plant. However, given our technological inputs, this was a trivial result. Less trivial was consideration of the negative effects that might accrue through the availability of potentially unlimited supplies of low cost energy. It is concluded that while there may be reasonable humanist argument both for and against such abundance, in a democratic society control of energy development for its own sake is likely to be unacceptable. However, if the indirect effects of pollution, despoilment, and resource depletion through ever expanding energy use become sufficiently disturbing to the well-being of the majority, unlimited energy may come to be seen as undesirable by the society. To this extent successful research and development for unlimited sources such as the fusion or mixed solar alternatives might be judged from some point far in the future to have been a mistake. This could occur even though advances in the technology of pollution control and resource use greatly reduce the pollution and hazard accompanying a much higher rate of energy utilization.
