Questions on NEA program for OMB budget presentation

Description: The questions asked and answered include: Why was the program renamed from PNE (Peaceful Nuclear Explosives) to NEA? Why are storage cavities needed? Why can`t existing caves and mines be used? Isn`t a mined cavity safer for radioactive disposal? Why can`t one tolerate asymmetry between the US and USSR PNE capability? Why do we need PNE execution capability to support verification capability? Why shouldn`t the money go directly to verification? What is the priority of PNE research compared to other energy technology research? What is the US obligation under Article V of the NPT if it is determined that PNE`s are not worthwhile? What new information is available which shows that PNE`s will be politically acceptable? How much has been spent to develop PNE`s to date? What viable technology has resulted? The remainder of the paper discusses research programs being carried out on nuclear explosion technology and one technology that has resulted from the PNE program, namely, stimulation of oil and gas extraction.

LLL comments on The Ultimate Catastrophe

Description: This correspondence provides a discussion of purported hazards of nuclear energy production and weapons research. The possibility of atmospheric burn and oceanic burn are discounted, and the cross sections of Nitrogen are investigated and the concentration of D[sub 2]O in the oceans are considered. In conclusion, extremely conservative calculations demonstrated that it is completely impossible for either the earth`s atmosphere or sea to sustain fusion reactions of either thermonuclear nuclear chain reaction type. And, in particular, such reactions cannot be triggered by the explosion of nuclear weapons, even those having unrealistically high yield and impractical high yield-to-weight.

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 the accuracy of the model predictions.

Investigation of Nonmetallic Waterstops Report 9: Final Report of Effect of Exposure

Description: Final report describing the results of experiments to test samples of rubber, synthetic rubber, and polyvinylchloride (PVC) to determine their suitability for use in nonmetallic waterstops. During the tests, each of the samples was exposed to various conditions and environments before evaluation. This report discusses longer exposures of materials, to follow the previous report in the series discussing an evaluation of the same tests.

Experiment DTA report for semiscale transparent vessel countercurrent flow tests

Description: Steady state air-water tests were performed as part of the Semiscale Blowdown and Emergency Core Cooling (ECC) Project to investigate downcomer countercurrent flow and downcomer bypass flow phenomena. These tests were performed in a plexiglass representation of the Semiscale pressure vessel which allowed changes to be madein the geometry of the upper annulus and downcomer for the purpose of investigating the sensitivity of downcomer and bypass flow to changes in system geometry. Tests were also performed to investigate the effects of two-phase inlet flows and different initial system pressures on countercurrent and bypass flow. Results for each test are presented in the form of computer printout of the measurements and of a summary of the pertinent calculated flow rates, pressures, and dimensionless volumetric fluxes. Descriptions of the test facility, instrumentation, operating procedures, and test conditions are also presented. An error analysis is presented for selected volumetric flux calculations. 10 references. (auth)

Quantitative evaluation of the RETIMAC system

Description: One means of raising the degree of protection afforded strategic special nuclear materials against theft and diversion is the installation of Real Time Material Control (RETIMAC) systems. The ability of RETIMAC to detect any covert attempt to steal special nuclear materials in a time frame that is adequate to contain subcritical quantities of special nuclear material within the boundaries of the material protection system and to maintain current knowledge of the quantity and location of all strategic special nuclear material was tested. A commercial-scale mixed oxide fuel fabrication plant was chosen for the study. (LK)

Porous body model for predicting temperature distributions in wire wrapped fuel and blanket assemblies of a LMFBR

Description: Existing methods of thermal analysis of a wire wrapped rod bundle of a Liquid Metal Fast Breeder Reactor are based on the principle of subchannel analysis. A model for thermal transport in wire wrapped rod bundles is developed here. The model is similar in principle to the one which has long been successfully used in chemical engineering for heat and mass transfer in fixed beds of packed solids. By dividing the bundle into two predominant regions and applying the model of a porous body to a LMFBR assembly a simple procedure for calculating temperature distributions in LMFBR fuel and blanket assemblies has evolved. The results obtained were found to predict available data with as good a precision as do the more complex analyses. Correlations for the two empirical constants were obtained as functions of geometric parameters based on an extensive analysis of existing data. The LMFBR fuel assemblies operate in forced convection (negligible natural convection) under steady state conditions whereas the blanket assemblies may operate in forced or mixed convection (combined forced and free convection). Two different formulations of equations, corresponding to these two convection regimes, were developed using the same basic model. The calculation procedure for assemblies in forced convection (called ENERGY I) is considerably simpler than that (ENERGY II, ENERGY III) in mixed convection, where buoyancy effects become important. Therefore it is desirable to use ENERGY I for forced convection (although ENERGY II, III can also be used in forced convection, the computational times are fifteen fold greater). In order to determine when buoyancy effects become important a new criterion is developed. Given the power, the power skew, the operating and geometric characteristics of the bundle, the critical modified Grashof Number predicts when buoyancy effects become important. (auth)
