Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Description: Partial abstract: "This report is based: (1) on information developed in earlier high explosive experiments which determined the optimum spacing and burial depth of charges in a row to produce a channel uniformly wide and deep, and (2) on the Sedan and Danny Boy experiments, which provided data on dimensions of nuclear craters in both soil and basalt rock. This information has been combined with the 1947 route surveys of the Panama Canal company, and estimates have been made not only of the num… more

MIT extraction method for measuring average subchannel axial velocities in reactor assemblies

Description: The MIT extraction method for obtaining flow split data for individual subchannels is described in detail. An analysis of the method is presented which shows that isokinetic values of the subchannel flow rates are obtained directly even though the method is non-isokinetic. Time saving methods are discussed for obtaining the average value of the interior region flow split parameter. An analysis of the method at low bundle flow rates indicates that there is no inherent low flow rate limitation on… more

Physical Hydraulic Models: Assessment of Predictive Capabilities; Report 1: Hydrodynamics of the Delaware River Estuary Model

Description: 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 th… more

The Effects of Hearsee/Say and Hearsee/Write on Acquisition, Generalization and Retention.

Description: This study examines the effects of training in two yoked learning channels (hearsee/say and hearsee/write) on the acquisition, generalization and retention of learning. Four fifth-grade participants were taught the lower-case letters of the Greek alphabet. Twelve letters were taught in the hearsee/say channel and twelve letters taught in the hearsee/write channel for equal amounts of time. The see/say channel reached higher frequencies at the end of training and showed higher acquisiti… more

Effect of power on demand surface and flow instability for annular geometry fuel elements with upflow of coolant

Description: Analytical studies of the effects of power on flow instability in parallel channels with upward flow of coolant, have predicted that the Ledinegg flow instability, encountered as flow is decreased for typical operating power levels, would not be experienced at low power levels. For a system in which the flow of coolant is upward, the increased buoyancy enhances flow in the channel, so that as the void increases, the overall pressure loss decreases. Under this condition, flow instability does no… more
