Absorption corrections for x-ray fluorescence analysis of environmental samples

Description: The discovery of a very simple and useful relationship between the absorption coefficient of a particular element and the ratio of incoherent to coherent scattering by the sample containing the element is discussed. By measuring the absorption coefficients for a few elements in a few samples, absorption coefficients for many elements in an entire set of similar samples can be obtained. (auth)

Advance notice of proposed rulemaking. Chapter II, subchapter D. Energy conservation; Part 440. Weatherization assistance for low-income persons

Description: Proposals to amend Appendix A of Part 440 of Weatherization Assistance for Low-Income Persons are described. The proposals establish new specifications for the materials purchased for utilization in the weatherization of dwellings which qualify for assistance under Part 440. These proposed regulations prescribe the minimum requirements which must be met or exceeded by each type of material and the Federal standards to which they must conform. In addition, these regulations include installation … more

Algorithms and FORTRAN programs to calculate classical collision integrals for realistic intermolecular potentials. [Classical transport integrals; SCAN; Coll]

Description: Numerical methods and computer programs are given to evaluate, for an arbitrary intermolecular potential, the classical transport collision integrals which appear in the kinetic theory of dilute gases. The method of Gaussian quadrature was employed to integrate the triple integral. A detailed discussion is given of the mathematics necessary to determine the boundaries of the individual integrations as well as a detailed analysis of errors introduced by the numerical procedures. Results for a re… more

Analytical study of TATB preheating methods

Description: TATB (1,3,5 - triamino 2,4,6 - Trinitrobenzene) is a very stable explosive that is remarkably insensitive to severe impact and thermal environment. Experiments on its initiation and detonation characteristics have found it difficult to initiate under the energy transfer of thin flyer plates accelerated by electrically exploded metal foils. Figure 1 shows the propagation of a detonation front in such an experiment. Generally, the detonation waves are confined in the region directly in front of t… more

Automated explosive pellet manufacturing using a PDP-14 programmable controller

Description: A Digital Equipment Corporation PDP-14 Industrial Programmable Controller was employed to provide automatic, closed-loop control for an explosive pellet manufacturing system at Mound Laboratory. Programmable controllers allow the application of sophisticated and flexible control, through programming. Advantages of the PDP-14 controller are ease of installation and maintenance, capability for modular expansion, and immunity to electrical noise. Safety requirements were met by using new technique… more

Calculated and measured efficiency of a man-portable /sup 3/He neutron detector

Description: A small man-portable neutron detector was constructed using 18 /sup 3/He proportional counters arranged in three layers within a polyethylene moderator. Each counter is 25 mm in diameter by 340 mm long (sensitive length) and is filled with highly-purified /sup 3/He to a pressure of 400 kPa (4 atm). Efficiency measurements were made using a /sup 252/Cf neutron source. Detailed calculations of the detector efficiency were done using the TART Monte Carlo transport code. Calculations and measuremen… more

Case studies of geothermal leasing and development on federal lands

Description: In response to a widely expressed need to examine the impact of the federal regulatory system on the rate of geothermal power development, the Department of Energy-Division of Geothermal Energy (DGE) has established a Streamlining Task Force in cooperation with appropriate federal agencies. The intent is to find a way of speeding development by modification of existing laws or regulations or by better understanding and mechanization of the existing ones. The initial focus was on the leasing and… more

Coil winder for the magnet of the mirror fusion test facility

Description: A coil winder was designed for the purpose of fabricating the superconducting magnets of the Mirror Fusion Test Facility. The superconducting magnets are a displaced ying-yang pair, each having major and minor radii of 2.5 and 0.75 m, respectively, and cross section of 0.42 m by about 1.03 m. The superconductor cross section is a square, 13 mm on a side, and consists of a core of niobium-titanium embedded copper and a solid copper stabilizer. Conceptual studies made at Lawrence Livermore Labora… more

Compact 80-keV neutral-beam module

Description: A compact and maintainable source of 80-keV neutral beams that focus to a high power density is required for the Mirror Fusion Test Facility (MFTF). In the new source being designed and built to meet these requirements, the cross-sectional area is reduced in two ways: by immersing the source in a vacuum where high voltage can be held over smaller distances and by redesigning grid supporting structures. Reliability is increased by reducing the electric fields everywhere else below those present … more

Computational features of the CACECO containment analysis code. [LMFBR]

Description: A code, CACECO, has been written to assist in the analysis of containment situations peculiar to sodium cooled reactors. Typically, these situations involve relatively slow energy release processes and chemical reaction heat. Two examples are given to illustrate some of the code's features. These particular cases illustrate the potential for hydrogen formation in the containment building, but show that time is available to take corrective action. The code is suitable for other problems involvin… more
