The objectives of the work are to develop mathematically and computationally founded for the design of highly efficient and reliable multidimensional neutron transport codes to solve a variety of neutron migration and radiation problems, and to analyze existing and new methods for performance. As new analytical insights are gained, new numerical methods are developed and tested. Significant results obtained include implementation of the integer-preserving Gaussian elimination method (two-step method) in a CDC 6400 computer code, modes analysis for one-dimensional transport solutions, and a new method for solving the 1-T transport equation. Some of the work dealt with the interface and corner problem in diffusion theory. (RWR)

From purpose and scope: The purpose of the present study by the U.S. Geological Survey in cooperation with the Division of Water Resources of the New Jersey of Environmental Protection is to make a quantitative hydrologic analysis of the known buried valley-fill aquifer in southwestern Essex and southeastern Morris County Counties in order to provide water-resources planners with the hydrologic bases to plan ground-water development and to allocate available water.

Abstract: Flow in the unconsolidated glacial deposits near the city of Carmel in central Indiana was simulated by a digital-computer model in a study of hydraulic characteristics of the deposits. The study shows that 21 • 3 million gallons per day (933 liters per second) of additional water could be withdrawn from the aquifer for an indefinite period of time. This pumpage is approximately 5 million gallons per day (219 liters per second) above the projected water needs of Carmel for 1990. Saturated thickness, transmissivity, and storage coefficient of the outwash aquifer along the White River east of Carmel were determined, using available data supplemented by test drilling . The saturated thickness of the aquifer ranges from 10 to 110 feet 0 to 34 meters ); transmissivity ranges from 1,000 feet squared per day (93 meters squared per day) to 24 ,000 feet squared per day (2 ,230 meters squared per day); and the average storage coefficient is 0.11.

Abstract: Annual pumpage for both the Memphis Sand ("500-foot" sand) and Fort Pillow Sand ("1400-foot" sand) from the time of initial pumping from these aquifers to 1975 is presented in both tabular and graphic forms . The Memphis Sand supplied 188 million gallons per day in 1975 or 95 percent of the total water used in the area . Pumpage from the Fort Pillow Sand has decreased in recent years and in 1975 was about 4 million gallons per day. Pumping increases from the Memphis Sand have caused an almost continual decline of water levels as shown by graphs , tables, and a series of potentiometric-surface maps. Water-level-change maps show the fluctuations in water levels for two periods of high water use. Water levels in the Fort Pillow Sand are also shown by tables and graphs and a potentiometric-surface map . These graphs illustrate a rise of water levels since 1963, coincidental with pumping reductions. The data presented suggest that a constant pumping rate will cause little water-level decline and that the water levels can be altered for efficient resource management by areally varying the distribution of pumping . The references listed support the information presented in this report .

This report details the federal and state laws regarding animal baiting and fighting. In general, this report found three types of state statutes on this matter: specific legal prohibition aimed at stamping out a practice considered either distasteful, immoral, or a nuisance; general animal cruelty provisions enacted into law which may or may not be held applicable to baiting and fighting or any or all animals, and which may be not be enforced against those involved in such activities; and the absence of statutory restraints due either to open acceptance of animal baiting and fighting as a harmless activity or due to lack of concern over the matter.

Highly accurate finite difference schemes are developed for Laplace's equation with the Dirichlet boundary condition on general bounded regions in R/sup n/. A second order accurate scheme is combined with a deferred correction or Richardson extrapolation method to increase the accuracy. The Dirichlet condition is approximated by a method suggested by Heinz-Otto Kreiss. A convergence proof of his, previously not published, is given which shows that, for the interval size h, one of the methods has an accuracy of at least O(h/sup 5/./sup 5/) in L/sub 2/. The linear systems of algebraic equations are solved by a capacitance matrix method. The results of our numerical experiments show that highly accurate solutions are obtained with only a slight additional use of computer time when compared to the results obtained by second order accurate methods.

Data are reported on the cycling of /sup 36/Cl-labeled DDT in an old field ecosystem. Data are included on the content of DDT retained in samples of soil, plants, invertebrates, and tissues of small mammals. The body burden of DDT in both earthworms and slugs decreased during the six-year period whereas that of isopods increased, indicating that the food chain sources of the compound differ among soil invertebrates.

Report on the Ogallala Aquifer in Lamb County, Texas, with a focus on the fact that the area currently uses 10 times more water than the aquifer can replenish per year.

The BSR operated at an average power level of 1,996 kw for 31.93 percent of the time during the report period. Water-quality control in both the reactor primary and secondary cooling systems was satisfactory. An unscheduled shutdown occurred on October 31, 1975, because of water loss from the pool at a rate of 1.6 gpm, apparently due to several small leaks. The reactor fuel was transferred to the OGR Canal Storage and the pool water level lowered to the pool floor. Defective areas in the concrete pool walls and floor are being chipped, grouted and sealed in preparation for applying fiberglass and repainting. Pool repairs accounted for 98 percent of the downtime reported. The PCA was not used during this report period and remains in a secured condition.

The BSR operated at an average power level of 1,878 kw for 38.00 percent of the reporting period. Water-quality control in both the reactor primary and secondary cooling systems was satisfactory. There were two unscheduled shutdowns during the quarter. The PCA was not used during the report period and remains in a secured condition.

Several new or poorly characterized neutron-rich nuclides were produced and studied at the Brookhaven Medium Energy Intense Neutron facility, MEIN. /sup 190/W decays with T/sub 1/2/ = 30.0 +- 1.5 min, E/sub beta/ = 0.93 +- 0.07 MeV, and ..gamma..'s of 157.6 and 162.1 keV. /sup 196/Os decays with T/sub 1/2/ = 35.0 +- 0.4 min and ..gamma..'s at 126.1, 200.7, 207.0, 257.0, 315.3, 407.6, 522.2, and 628.9 keV. /sup 230/Ra decays with T/sub 1/2/ = 93 +- 2 min to 122 +- 3 sec /sup 230/Ac; ..gamma..-ray energies and intensities are tabulated. A decay scheme is proposed for /sup 190/W, and many of the transitions following the decay of /sup 230/Ac are between known levels in /sup 230/Th.

Various factors that can affect thermal blooming in stagnation zones are examined, including stagnation-zone motion, longitudinal air motion in the neighborhood of the stagnation zone, and the effects of scenario noncoplanarity. Of these effects, only the last offers any reasonable hope of reducing the strong thermal blooming that normally accompanies stagnation zones; in particular, noncoplanarity should benefit multipulse more than cw beams. The methods of treating nonhorizontal winds hydrodynamically for cw and multipulse steady-state sources are discussed. Pulse ''self-blooming'' in the triangular pulse approximation is discussed in the context of both single and multipulse propagation. It is shown that self-blooming and multipulse blooming cannot be treated independently.

Commercial refractories of alumina, magnesia, zirconia, and silica, as well as samples of graphite, thoria, beryllia, boron carbide, and quartz, were tested for compatibility with high-temperature and boiling sodium. Samples were exposed either to static sodium at 850/sup 0/C for five hours or to boiling sodium for about an hour. Graphite, thoria, beryllia, boron carbide, and refractories with high alumina or magnesia contents, but with low silica and chromic oxide contents, were found to be compatible with high-temperature and boiling sodium. Sample compatibility with sodium decreased with an increase in the silica content of the sample. Samples with large silica content failed completely. Bricks with high zirconia content did not withstand exposure to boiling sodium, but high-fired zirconia crucibles appeared to be in good condition after sodium exposure. Except for the results with the high-zirconia bricks, the results of the ANL experiments with refractory bricks are in good agreement with those obtained in sodium compatibility experiments done at Westinghouse Advanced Reactors Division. 36 Figs.
