From introduction: In conventional safety analyses, a suitable design basis, including redundancy, is specified to assure a minimum level of operability of ESFs, and the likelihood or consequences of total failure of ESFs are not considered further. In this study all failures are considered possible, but appropriate probabilities are assigned to them. Thus, many potential accident sequences are described in the following discussions as if they will surely occur, with no reservations expressed as to their likelihood or significance. However, most of these sequences have such low probability that they do not contribute to the overall risk from reactor accidents. In fact, in order to make an overall risk assessment, a major task of this study was to identify the sequences that are the dominant contributors to risk. In this study the initial failures or initiating events that could lead to significant consequences were examined to varying degrees. Those that seemed to contribute significantly to potential risks were analyzed in considerable detail; those that did not, received less detailed consideration. This is discussed more fully in section 3 of this appendix.

From section 1: In the quantitative system probability estimates performed in this study, component behavior data in the form of failure rates and repair times are required as inputs to the system models. Since the goal of this study is risk assessment, as opposed to reliability analysis, larger errors (e.g. order of magnitude type accuracy) can be tolerated in the quantified results. This has important implications on the treatment of available data. In standard reliability analysis, point values (i.e., "best-estimates") are generally used for both data and results in quantifying the system model. In risk assessment, since results accurate to about an order of magnitude are sufficient, data and results using random variable and probabilistic approaches, can be usefully employed. The base of applicable failure rate data is thus significantly broadened since data with large error spreads and uncertainties can now be utilized. The data and associated material that were assembled for use in this study and that are presented here are to be used in the random variable framework (which will be described). The data and the accompanying framework are deemed sufficient for the study's needs. Care must be taken, however, since this data may not be sufficiently detailed, …

Partial abstract: The purpose of this study is to define the reliability with which results of tests conducted in a physical model of the Delaware River Estuary can be used to predict the effects of modifications to the estuary. The Delaware River model at the Waterways Experiment Station was used to conduct tests to predict the effects of the navigation channel enlargement between Philadelphia and Trenton, and the results of the tests are compared with subsequent prototype data to determine the accuracy of the model predictions.

Introduction: This report presents the results of a subsurface uranium favorability study of the Morrison Formation in southwestern Colorado and southeastern Utah. The project began November 1, 1974 and was concluded April 11, 1975. The study was carried out under the auspices of the Grand Junction Office of the Energy and Research Development Administration (ERDA).

From introduction: This report covers the results of an ERDA-sponsored study to provide a preliminary evaluation of the uranium potential of the central portion of the Great Plains. It was carried out by the University of Kansas under contract number AT (05-1)-1642. This work is part of the ERDA National Uranium Resource Evaluation (NURE) Program. Texas Instruments Incorporated contributed to the study as a subcontractor.

"This study constitutes a determination of the extent to which it is feasible to use airborne, high-sensitivity gamma-ray spectrometer systems for uranium reconnaissance in the State of Alaska, and specification of a preliminary plan for surveying the entire state of the 1975-1979 time frame."--Page iii.

This report of figures and tables is the first on the entirety of aquifers in Mississippi.

From purpose and scope: The purpose of this investigation is to 1) study the hydrologic system in a glaciated terrain typified by numerous lakes, with particular focus on the effects of lake-ground-water interchange, 2) simulate the natural system by using two digital modeling methods--areal (map view) and vertical section, and 3) evaluate the utility of the models and determine the kinds and amount of basic data needed to obtain reasonable simulations.

Abstract: An intensive study was made of a 24-square mile (62-square kilometer) area surrounding the South Bend wastewater treatment plant to document the effects of dewatering about 40 feet (12 meter) of the 130-feet (40-meter) thick aquifer during construction at the plant, define the hydrologic system in order to allow development of a predictive model and select and evaluate one possible water-supply development plan as a model demonstration. Model-simulated water levels agree very well with those observed, both before and during dewatering. Model results indicate that the hydrologic system can sustain withdrawal of 28 million gallons per day (106,300 cubic meter per day) indefinitely with little effect on ground-water levels. The quantity that would be diverted from the St. Joseph River is less than 10 percent of the estimated minimum daily flow.

Introduction: This report summarizes the results of the study and presents technical information on the water resources of the basin for hydrologists, engineers, planners, and water managers who need this knowledge to guide their endeavors. A brief lay-reader report describing this study is also in preparation for those who may be interested in the general findings and highlights of the investigation without the detail and data compilations contained in this report.

From introduction: The purpose of this report is to describe the hydrologic system in the Lake Wingra basin, with particular emphasis on the hydrolic budget of the lake itself.

From introduction: A large amount of information is available on the aquifers of Mississippi. Reports resulting from various areal studies have described the ground-water resources of the areas concerned, but no reports dealing specifically with statewide occurrence of individual aquifer systems have been prepared previously. A series of "aquifer atlases" was deemed the most effective way to point out the character, the potential, and the extent of development of the aquifers and thereby provide water managers with data needed for efficient utilization of available resources. This report on Miocene aquifer system is the first in the series.

Abstract: The various components of inflow and outflow to and from the lake and their relative magnitudes were identified. In 1972 water year the total inflow to the lake was 200,000 acre-feet, but it was only 75,000 acre-feet in 1973 water year. In 1972 water year the Donner and Blitzen River contributed 55 percent of the inflow, with Silvies River, direct precipitation, and Sodhouse Spring contributing 28, 13, and 4 percent respectively. Om 1973 the Donner and Blitzen River contributed 61 percent of the inflow. The Silvies River, direct precipitation, and Sodhouse Spring contributed 1, 25, and 12 percent respectively. Ground-water inflow, other than Sodhouse Spring, appears to be negligible. In 1972 water year, 81 percent of the outflow was by evapotranspiration and 19 percent was surface outflow through The Narrows. In 1973, 96 percent of the outflow was by evapotranspiration and 4 percent was surface outflow through The Narrows. Ground-water outflow is negligible.

Abstract: The Viking Basin consists of six glacial outwash areas in Douglas, Ottertail, and Todd Counties, west-central Minnesota. Total area is 340 square miles (880 square kilometers). Soils are sandy and excessively well-drained. Crops grown on the outwash would benefit from supplemental irrigation. Irrigation supplies can be obtained from wells in the surface outwash aquifer in significant parts of the large outwash areas near Carlos and Parkers Prairie and the small outwash area near Clotho. Irrigation supplies are unlikely in the outwash areas near Alexandria, Urbank, and Rose City. Major use of ground water for irrigation may lower ground-water levels sufficiently to affect lake and marsh levels and streamflow out of the irrigation areas. Water from the outwash is of excellent chemical quality for irrigation.
