Preimpoundment Water Quality of Raystown Branch Juniata River and Six Tributary Streams, South-Central Pennsylvania

Description: Abstract: The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometers) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary streams in the basin. Specific conductance values varied inversely with water discharge. The pH values were extremely low only at the Shoup Run site. Dissolved oxygen concentrations observed at all sites indicat… more

Geology and Ground-Water Resources of Camden County, New Jersey

Description: From introduction: The purpose of this investigation is to collect and interpret the basic hydrologic and geologic data and to appraise and report on the ground-water resources of Camden County. The objectives were to define the thickness and areal extent of the hydrologic units, evaluate the hydraulic characteristics of the aquifers, determine the effect of pumpage on the water levels of the area, define the source of recharge of the aquifers, and to evaluate the chemical quality of the ground… more

Technical Manual For Estimating Low-Flow Frequency Characteristics of Streams in the Susquehanna River Basin

Description: Abstract: This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided into two types major and minor. Major streams are the Susquehanna, West Branch Susquehanna, Juniata, and Chemung Rivers. Points on these streams with drainage areas of more than 2,000 square miles (5,180 kilom… more

Nitrogen and Phosphorus Uptake in the Everglades Conservation Areas, Florida, with Special Reference to the Effects of Back-pumping Runoff

Description: From purposes and scope: The purposes of this investigation are to make a qualitative assessment of the effects on water quality of pumping water into the conservation areas, and specifically to evaluate the uptake by sediment and biota of nitrogen, phosphorus, and selected trace elements contained in the water.

The Changeable Interaction between Soils and Pressure Cells: Tests and Reviews at the Waterways Experiment Station

Description: Partial abstract: "The principal subjects of the report are the often neglected changes in the interaction of soil and pressure cells with consequent changes in relative errors in cell registrations. The report contains (a) a brief account of the development and use of soil pressure cells; (b) a review of proposed theories for soil-cell interaction; (c) a delayed account of tests with Waterways Experiment Station pressure cells placed in a large triaxial device; and (d) tentative conclusions pl… more

Finite-Element Analysis of a Thick-Wall Tube Containing a Crater-Like Surface Flaw

Description: A three-dimensional finite-element elastic analysis is carried out for a thick-wall tube (as sued in typical LMFBR steam generators) that contains a surface flaw in the form of a paraboloid of revolution. Effects of the depth and aspect ratio of the flaw on the stress distribution and stress concentration in the tube are explored.

Investigation of Reactivity Anomalies in EBR-II

Description: A data-collection and advisory team was formed to investigate observations of power reactivity decrement (PRD) and reactivity loss rate (RLR) obtained during EBR-II reactor run 74, because both the PRD and RLR were judged to be high during that run. This report describes the efforts to develop a realistic model explaining the reactivity observations for run 74 and presents recommendations for additional diagnostic information in the event of a recurrence of off-normal behavior of reactivity.

Reactivity and Power Shape Control : Theory and Numerical Applications

Description: An optimization method, based on linear programming, has been developed which determines the enrichment distribution in a multizone reactor such that the desired power distribution is achieved at BOL, as well as the poison distribution during reactor operation such that the reactor is kept critical and the desired power distribution is retained. For the numerical implementation of the method, the CYPRUS code has been written. Results of the application of the method are presented and input spec… more

A Summary on Experimental Methods for Statistical Transient Analysis of Two-Phase Gas-Liquid Flow

Description: Much work has been done in the study of two-phase gas-liquid flows. Although it has been recognized superficially that such flows are not homogeneous in general, little attention has been paid to the inherent discreteness of the two-phase systems. Only relatively recently have fluctuating characteristics of two-phase flows been studied in detail. As a result, new experimental devices and techniques have been developed for use in measuring quantities previously ignored. This report reviews and s… more

Fuel Dynamics Loss-of-Flow Test L3 : Final Report

Description: The behavior of FTR-type, mixed-oxide, pre-irradiated, ''intermediate-power-structure'' fuel during a simulation of an FTR loss-of-flow accident was studied in the Mark-IIA integral TREAT loop. Analysis of the data reported here leads to a postulated scenario (sequence and timing) of events in the test. This scenario is presented, together with the calculated timing of events obtained by use of the SAS code.

Theory of Ionization by Electron Collisions

Description: The problem of calculating comprehensive sets of cross sections for ionization of atoms and molecules is reviewed. Emphasis is put on targets that are already ionized and lower-energy collisions for which the incident electron must be treated on a par with target electrons. The physical circumstances are discussed in which perturbation methods should be adequate, and special investigations are recommended to identify the relevant ranges of parameters more precisely and dependably. A new R-matri… more

Automatic Measurement of Network Parameters: A Survey

Description: Report issued by the Bureau of Standards over a survey conducted on measurement methods of network parameters. As stated in the introduction, "this paper is concerned with the development of automatic methods of measuring basically the magnitudes and phase differences, or the complex ratio of two sinusoidal voltages, and applications of this capability to determining complex reflection coefficients and transmission coefficients and group delay times of electrical networks" (p. 1).
