Experimental electro-thermal method for nondestructively testing welds in stainless steel pipes

Description: Welds in austenitic stainless steel pipes are notoriously difficult to nondestructively examine using conventional ultrasonic and eddy current methods. Survace irregularities and microscopic variations in magnetic permeability cause false eddy current signal variations. Ultrasonic methods have been developed which use computer processing of the data to overcome some of the problems. Electro-thermal nondestructive testing shows promise for detecting flaws that are difficult to detect using other… more

New applications of high-temperature solar energy for the production of transportable fuels and chemicals and for energy storage

Description: The solar fuels and chemicals study was limited to the examination of processes requiring temperatures in excess of 1000/sup 0/K since lower temperature processes had already been examined in studies concerned with the application of waste heat from nuclear power plants to industrial processes. In developing the carbon cycle processes, the primary activity included an extensive literature search and the thermodynamic evaluation of a number of candidate chemical cycles. Although both hydrogen an… more

Tabular equation of state of lithium for laser-fusion reactor studies

Description: A tabular lithium equation of state was formulated from three separate equation-of-state models to carry out hydrodynamic simulations of a lithium-waterfall laser-fusion reactor. The models we used are: ACTEX for the ionized fluid, soft-sphere for the liquid and vapor, and pseudopotential for the hot, dense liquid. The models are smoothly joined over the range of density and temperature conditions appropriate for a laser-fusion reactor. We also fitted the models into two forms suitable for hydr… more

Proliferation resistance design of a plutonium cycle (Proliferation Resistance Engineering Program: PREP)

Description: This document describes the proliferation resistance engineering concepts developed to counter the threat of proliferation of nuclear weapons in an International Fuel Service Center (IFSC). The basic elements of an International Fuel Service Center are described. Possible methods for resisting proliferation such as processing alternatives, close-coupling of facilities, process equipment layout, maintenance philosophy, process control, and process monitoring are discussed. Political and institut… more

Clastic dikes of the Pasco Basin, Southeastern Washington. Final report

Description: Clastic dikes are planar features, commonly wedge shaped in cross section, with their apices mostly downward. They are filled with clastic sediments from clay to gravel in size. Three days were spent in the Pasco Basin examining clastic dikes in 10 localities. It was clear from the field observations, summarized in the text, that the features called clastic dikes are multigenetic. Previously proposed theories of origin of the initial fractures, involving earthquakes, desiccation, deep frost cra… more

Calculations of the transverse spatial distribution of NE102 scintillation light made by recoil protons from collimated 14-MeV neutrons

Description: A calculation has been made of the spatial distribution of NE102 scintillation light produced by recoil protons from collimated 14-MeV neutron illumination. Results were then averaged over offset circles of various radii, thus determining the fraction of the total scintillation light created inside cylindrical scintillators for uniform neutron illumination over the front face of the scintillator. The results are useful in sensitivity considerations for neutron-imaging camera design.
