Probability based load criteria for the design of nuclear structures: a critical review of the state-of-the-art

Description: Structures for nuclear power plant facilities must be designed to withstand safely and effectively all kinds of loads and load combinations that may be expected to occur during their lifetime. The traditional methods of structural design attempt to account for the inevitable variability in the loads, material strengths, in-service environments, and fabrication process, etc., through the use of safety factor, allowable stresses or load and resistance factors. These approaches may result in an un… more

Polarized negative ions

Description: This paper presents a survey of methods, commonly in use or under development, to produce beams of polarized negative ions for injection into accelerators. A short summary recalls how the hyperfine interaction is used to obtain nuclear polarization in beams of atoms. Atomic-beam sources for light ions are discussed. If the best presently known techniques are incorporated in all stages of the source, polarized H/sup -/ and D/sup -/ beams in excess of 10 ..mu..A can probably be achieved. Producti… more

Infiltration measurements in audit and retrofit programs

Description: A model that relates fan pressurization measurements to infiltration values during the heating season is the basis for infiltration estimates in several different audit programs. The model is described and validation results are presented. The model is used in three different audit strategies. The first is an energy audit to determine economically optimal retrofits for residential buildings, based on actual, on-site measurments of key indices of the house. Measurements are analyzed on a micropr… more

Application of microfabrication technology to thermionic energy conversion. Final report, 1 April 1979-31 March 1981

Description: The first-year effort emphasized study of the kind of microstructures that could improve the performance of thermionic converters. Two ideas considered to have a fair chance of success emerged from this study: (1) use of a very closely spaced diode to eliminate the space-charge limitation of electron flow from emitter to collector, cesium vapor being used to control the work function of the emitter; and (2) use of field emission electrons, injected into a relatively large diode gap from microca… more

MT2D: an interactive two-dimensional magnetotelluric and line source modeling program (user's guide and documentation for Rev. 3)

Description: MT2D.REV3 is the latest revision of a 2-dimensional, finite-element, interactive MT-line source modeling program. The original program was a batch-mode program developed by John Stodt. An interactive program was developed based on Stodt's program for a UNIVAC 1108. The program uses linear interpolation of the unknown field over triangular sub-domains of the region where a solution is sought in conjunction with the Galerkin technique to derive a system of linear equations which approximate the g… more
