A method is described how a quantitative measure for the robustness of a given transport theory code for coarse network calculations can be obtained. A code, that performs this task automatically and at only nominal cost, is described and has been implemented for slab geometry. This code generates also user oriented benchmark problems which exhibit the analytic behavior at interfaces.

Two modeling programs, SCEPTRE and CSMP, are used to solve the point-kinetics equations - - seven coupled nonlinear differential equations - - with a linear-feedback function. The constants used are appropriate for EBR-II; therefore the computational accuracy may be tested against the experimental rod drops. Run-time, versatility, programming ease, and accuracy are criteria used to evaluate the two programs. SCEPTRE is found to be more efficient in run time and CSMP more versatile. The ease of programming is about the same for both programs. The accuracy is nearly equivalent if the optimum integration routines are used.

Ultrasonic inspection of large-grain stainless steel and stainless steel welds is difficult, and the results obtained are not easily interpreted. In the present study, the effects of stainless steel microstructure on ultrasonic test results are described, and several signal-processing techniques for enhancing ultrasonic flaw signals are discussed.

Technology utilization/commercialization is the process of applying technology to satisfy a preexisting need. The present report examines the organizational relationships involved, the controlling factors, and the role of the technology agent. Included is a brief assessment of the technology commercialization activities currently under way as part of specific research and development projects at Argonne National Laboratory. In addition to the usual supporting references, an appendix is devoted to a sampling of the relevant literature.

Abstract: This report summarizes the criteria for selection of those to be investigated, the investigation procedures, and the accident data obtained for the 33 in-depth investigations.

The reactor physics studies performed in the gas cooled fast reactor (GCFR) mockup on ZPR-9 are covered. This critical assembly, designated Phase II in the GCFR program, had a single zone PuO₂-UO₂ core composition and UO₂ radial and axial blankets. The assembly was built both with and without radial and axial stainless steel reflectors. The program included the following measurements: small-sample reactivity worths of reactor constituent materials (including helium); ²³⁸U Doppler effect; uranium and plutonium reaction rate distributions; thorium, uranium, and plutonium alpha and reactor kinetics. Analysis of the measurements used ENDF/B-IV nuclear data; anisotropic diffusion coefficients were used to account for neutron streaming effects. Comparison of measurements and calculations to GCFR Phase I are also made.

Map and survey information of the the Aravaipa Valley area in Arizona, including information on well depths, irrigated areas, approximate boundaries, and arbitrary boundaries of ground-water area, as well as general hydrologic data and selected references.

Abstract:Data were collected and summarized on the hydrology and hydrogeology of 949 lakes, 10 acres (4 hectares) or larger, in the Minneapolis-St. Paul metropolitan area, Minnesota. Eight tables totaling over 100 pages present data on location, depth, area, lake level, ecological and game-management classification, inflowing and outflowing streams, soils, bedrock type, water added to or take from lake, and reported lake-related problems. SYSTEM 2000, a generalized computer data-base management system, was used to organize the data and prepare the tables. SYSTEM 2000 provides powerful capabilities for future retrieval and analyses of the data. The data base is available to potential users so that questions not implicitly anticipated in the preparation of the published tables can be answered readily, and the user can retrieve data in tabular or other forms to meet his particular needs.

Abstract: WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1). With but a few exceptions, the thermochemical data, speciation, activity coefficients, and general calculation procedure of WATEQF is identical to the PL/1 version. This report notes the differences between WATEQF and WATEQ, demonstrates how to set up the input data to execute WATEQF, provides a test case for comparison, and makes available a listing of WATEQF.

Report and Geographical Survey. Report uses a streamflow-routing model to simulate the daily flow at Park Falls over the next ten years and includes several illustrations and tables.

Purpose and scope: The purpose of this report is to determine, as far as possible, the occurrence of buried aquifers and to describe their hydrologic characteristics and water-yielding capability. The evaluation is based mainly on 44 test holes drilled specifically for this investigation. These test holes are too widely spaced to correlate individual aquifers. Such correlation must await more detailed closely spaced test drilling. Forty-two test holes were drilled in the Brooten-Belgrade area; hence the mapping is restricted to this part. Two test holes were drilled in the Lake Emily area, allowing only one geologic section to be presented. PIan-view mapping would require considerable additional test drilling.

Abstract: Laguna La Torrecilla, Laguna de Pinones, Laguna San Jose, and Laguna del Condado, in the San Juan, Puerto Rico area, are located within a metropolitan area of more than 1 million people. Bathymetric maps made during the study, in 1973, showed that Lagunas La Torrecilla, San Jose, and del Condado have been modified by dredging and filling; whereas, Laguna de Pinones has remained in a near natural state. Laguna La Torrecilla has been dredged to a depth, in places, of about 18 metres, and Lagunas San Jose and del Condado, in places to about 11 meters. Dredging in the San Juan lagoons has been harmful, beneficial, and in a few instances has had little or no noticeable effect on the water quality. Usually, dredging in the connecting canals has been beneficial if the water entering the lagoons through the canals was of better quality than the water in the lagoon. Dredging in the mouths of lagoons has been beneficial; whereas, filling or blocking the mouths has been harmful.
