Analysis of x-ray production in TMX upgrade

Description: TMX Upgrade (TMX-U), a tandem mirror experiment at LLNL, will use high power microwaves for electron cyclotron resonant heating (ECRH). As demonstrated on Elmo Bumpy Torus (EBT) and related experiments which use similar heating techniques, high energy electron populations are created. In these devices, which run CW, significant x-ray production occurs and adequate shielding must be provided for personnel protection. TMX-U is a pulsed experiment; however, significant x-ray production is expected… more

Simple scaling model for exploding pusher targets

Description: A simple model has been developed which when normalized by experiment or Lasnex calculations can be used to scale neutron yields for variations in laser input power and pulse length and target radius and wall thickness. The model also illucidates some of the physical processes occurring in this regime of laser fusion experiments. Within certain limitations on incident intensity and target geometry, the model scales with experiments and calculations to within a factor of two over six decades in … more

A method to estimate the concentration of elements in smoke from burning vegetation growing in contaminated soil

Description: The Savannah River Site has areas where soil is contaminated with metals and/or radionuclides. Many of these areas are surrounded by native vegetation which is growing adjacent to the area and where the roots have penetrated into the contaminated soil of the area. In some cases vegetation has actually invaded the contaminated area. Even though the volume of contaminated vegetation is small, there are problems associated with its disposal. Vegetation decomposes quickly after burial and the volum… more

Assessment of a small pressurized water reactor for industrial energy

Description: An evaluation of several recent ERDA/ORNL sponsored studies on the application of a small, 365 MW(t) pressurized water reactor for industrial energy is presented. Preliminary studies have investigated technical and reliability requirements; costs for nuclear and fossil based steam were compared, including consideration of economic inflation and financing methods. For base-load industrial steam production, small reactors appear economically attractive relative to coal fired boilers that use coal… more

Potassium vapor topping cycle. Technical progress report, April 1--June 30, 1977

Description: The potassium vapor topping cycle is a concept for increasing the efficiency of the Rankine vapor cycle by raising the peak temperature by employing a potassium vapor cycle with a turbine inlet temperature of 1500 to 1600/sup 0/F (815 to 870/sup 0/C) in which the waste heat rejected from the condensing potassium vapor is transferred to boiling water and steam in a conventional steam cycle. An efficiency of about 50% is calculated for this cycle with a natural circulation potassium boiler fired … more

Preliminary evaluation of fluid chemistry in the East Mesa KGRA

Description: One of the major problems needing consideration when bringing a geothermal field into production is the anticipation and control of mineral precipitation in both the producing formations and production equipment. Prediction of the chemical interactions between natural multicomponent thermal fluids and the minerals comprising a producing formation can be accomplished by the study of equilibrium models approximating the natural system. Models are constructed from theoretically and experimentally … more

Proton decay: 1982

Description: Employing the current world average ..lambda../sub MS/ = 0.160 GeV as input, the minimal Georgi-Glashow SU(5) model predicts sin/sup 2/theta/sub W/(m/sub W/) = 0.214, m/sub b//m/sub tau/ approx. = 2.8 and tau/sub p/ approx. = (0.4 approx. 12) x 10/sup 29/ yr. The first two predictions are in excellent agreement with experiment; but the implied proton lifetime is already somewhat below the present experimental bound. In this status report, uncertainties in tau/sub p/ are described and effects of… more

Equation of state of vanadium. [To 3. 39 Mbar and 5 x 10/sup 4/ eV temperature]

Description: A new, wide-range equation of state (EOS) for vanadium is presented. The generation of this EOS was of a fast-response nature. That is, the data base was constructed very rapidly, the analysis was very cursory, and it was inserted into the Bi-linear Logorithm (BLL) EOS library in 3 to 5 days. The composite theoretical model incorporates condensed matter, ionization equilibrium, and multiphase physics. The theoretical EOS was compared with all available high-temperature and high-pressure data fo… more

Geometric perturbation theory and plasma physics

Description: Modern differential geometric techniques are used to unify the physical asymptotics underlying mechanics, wave theory and statistical mechanics. The approach gives new insights into the structure of physical theories and is suited to the needs of modern large-scale computer simulation and symbol manipulation systems. A coordinate-free formulation of non-singular perturbation theory is given, from which a new Hamiltonian perturbation structure is derived and related to the unperturbed structure.… more

Evaluation of regional effects of effluents from uranium production in New Mexico

Description: The Grants Uranium Region is a 2500 mile area of northcentral New Mexico which has produced about 40 percent of all domestic uranium, and holds over one-half of the current reserves. The increasing demand for uranium to fuel commercial nuclear power plants is resulting in rapid growth of the uranium industry and economic, social, and environmental changes are occurring. One of the environmental issues of this region is the concern for eventually unacceptable levels of air and water pollution fr… more

Vacuum system for the Tandem Mirror Experiment

Description: The Tandem Mirror Experiment (TMX) under construction at LLL is a Q-enhancement experiment using two mirror fields to ''plug'' a central solenoid field. Neutral beam injection supplies the energetic neutrals to the plug regions with attendant quantities of cold gas. The vacuum vessel consists of two large stainless steel tanks, which house the plug coils, joined by an aluminum central cell tank, which fits inside the existing solenoid coils from the 2XIIB experiment. The plug tanks are subdivid… more
