Recent developments in nuclear reaction theories and calculations
A brief review is given of some recent developments in the fields of optical model potentials; level densities; and statistical model, precompound, and direct reaction codes and calculations. Significant developments have occurred in all of these fields since the 1977 Conference on Neutron Cross Sections, which will greatly enhance the ability to calculate high-energy neutron-induced reaction cross sections in the next few years. 11 figures, 3 tables.

Model for H/sup -/, D/sup -/ production by hydrogen backscattering from alkali and alkali/transition-metal surfaces
A model for H/sup -/, D/sup -/ production by energetic particles reflecting from metal surfaces is discussed. The model employs the energy and angular distribution data derived from the Marlowe code. The model is applied to particles incident normally upon Cs, Ni, and Cs/Ni surfaces.

Environmental control technology survey of selected US strip mining sites. Volume 2B. Alabama. Water quality impacts and overburden chemistry of Alabama study site
As part of a program to examine the ability of existing control technologies to meet federal guidelines for the quality of aqueous effluents from coal mines, an intensive study of water, coal, and overburden chemistry was conducted at a surface coal mine in Alabama from May 1976 through July 1977. Sampling sites included the pit sump, a stream downgrade from the mine, the discharge from the water treatment facility, and a small stream outside the mine drainage. Water samples were collected every two weeks by Argonne subcontractors at the Alabama Geological Survey and analysed for the following parameters: specific conductance, pH, temperature, acidity, bicarbonate, carbonate, chloride, total dissolved solids, suspended solids, sulfate, and 20 metals. Analysis of the coal and overburden shows that no potential acid problem exists at this mine. Water quality is good in both streams sampled, and high levels of dissolved elements are found only in water collected from the pit sump. The mine effluent is in compliance with Office of Surface Mining water quality standards.

Seismic hazard analysis for the NTS spent reactor fuel test site
An experiment is being directed at the Nevada Test Site to test the feasibility for storage of spent fuel from nuclear reactors in geologic media. As part of this project, an analysis of the earthquake hazard was prepared. This report presents the results of this seismic hazard assessment. Two distinct components of the seismic hazard were addressed: vibratory ground motion and surface displacement. (ACR)

Proceedings of the workshop on program options in intermediate-energy physics. Volume 1. Summary and panel reports
A Workshop on Program Options in Intermediate-Energy Physics sponsored by the US Department of Energy was held at Los Alamos Scientific Laboratory, August 20 to 31, 1979. The scope of the workshop included all laboratories in intermediate-energy physics, worldwide, and all of these sent representatives to the workshop. The workshop addressed itself to the critical questions on nuclear and particle physics and how they can best be investigated by intermediate-energy accelerators. Among the questions that the workshop members considered were: (1) what are the important physics topics which might be understood through research on these accelerators in the next 10 years. These topics include, but are not restricted to, fundamental interactions and symmetries in particle physics, and nuclear modes of motion, structure, and reaction mechanisms; (2) what experiments should be undertaken to carry out the program. What are the kinematical conditions, accuracies, resolutions, and other parameters required to obtain the desired knowledge; (3) which accelerators are best suited for each experiment. What work at other laboratories (low-, intermediate-, or high-energy) could be undertaken to complement and/or supplement the proposed LAMPF program; and (4) what new facility capabilities should be explored for the long-term future. The workshop was divided into small …

Workshop on instrumentation and analyses for a nuclear fuel reprocessing hot pilot plant
In order to assist in the study of instrumentation and analytical needs for reprocessing plants, a workshop addressing these needs was held at Oak Ridge National Laboratory from May 5 to 7, 1980. The purpose of the workshop was to incorporate the knowledge of chemistry and of advanced measurement techniques held by the nuclear and radiochemical community into ideas for improved and new plant designs for both process control and inventory and safeguards measurements. The workshop was athended by experts in nuclear and radiochemistry, in fuel recycle plant design, and in instrumentation and analysis. ORNL was a particularly appropriate place to hold the workshop since the Consolidated Fuel Reprocessing Program (CFRP) is centered there. Requirements for safeguarding the special nuclear materials involved in reprocessing, and for their timely measurement within the process, within the reprocessing facility, and at the facility boundaries are being studied. Because these requirements are becoming more numerous and stringent, attention is also being paid to the analytical requirements for these special nuclear materials and to methods for measuring the physical parameters of the systems containing them. In order to provide a focus for the consideration of the workshop participants, the Hot Experimental Facility (HEF) being designed …

Theoretical Evaluation of Thermal Imaging for Detection of Erosive Wear of Internally Refractory-Lined Transfer Lines
Infrared scanning has potential use in detecting erosive wear (thickness change) of the refractory surface of large-diameter steel pipes internally lined with refractory concrete, which are typical of those used in coal-conversion processes. An analytical study was conducted to determine the viability of this method. Heat-transfer models were developed to predict surface-temperature distributions on the outer metal surface for various erosive-wear conditions on the inner surface, assuming uniform inner-surface temperature. Variables investigated included thermal conductivity of the refractory concrete, thermal contact resistance between the steel shell and the refractory, outer-surface convective coefficient, outer-surface radiative properties, and refractory-lining thickness and composition. The study used two- and three-dimensional heat-transfer models and various well-defined rectangular cavities on the inner surface. Temperature resolution, and thus calculation of cavity sizes from surface-temperature profiles, is better when the convective coefficient is small and the interfacial contact resistance is uniformly low. The presence of dual refractory-concrete liners using a layer of insulating concrete between the hot-face lining and the steel shell, together with thick steel (t > 25 mm), tends to smear temperature patterns and reduce the temperature gradient so that calculation of cavity shapes becomes impractical.

Comprehension of Prose: Strategies Affecting Good and Poor High School Readers
The problem of this study was to investigate how good and poor comprehenders utilize passage structure and task instructions to acquire information from a prose passage. To give a more detailed picture of what type of information processing occurred during reading, both verbatim and paraphrase items were used to assess comprehension.There were two strong but nonsignificant patterns in the data for task instructions. Poor readers were sensitive to both attribute and relation instructions. Good readers, however, were not affected by attribute instructions, but were sensitive to relation instructions. The results for good readers tentatively suggest that they encode attributes as a natural part of reading, but only encode relationships when they are specifically instructed to do so. Based on these results, three observations were made. First, good readers appear not to be easily affected by text organization, but poor readers may be aided in comprehension by slight improvements in the organization of the text. Second, all students need more assistance and practice in drawing inferences from the text. Third, written instructions may be a weak aid for increasing the comprehension of poor readers and may help good readers attend to information they would normally miss.
