The design of future Engineering Test Reactor (ETR) to demonstrate ignition is complicated by the uncertainties in the projected database for ignited plasmas. Application of uncertainty analysis to ETR design utilizing a figure-of-merit defined as the probability of ignition is presented. Performance evaluation from the uncertainty analysis in density-temperature space can locate an optimum operating window for ignition. 11 refs., 5 figs., 3 tabs.

This in the third quarterly technical progress report for DE-AI2287PC79660 covering the period between 1 May and 31 July 1988. During this reporting period, the firing test of Dry Ultrafine Coal (DUC) in the 0.15 MB/H exploratory model has continued. Sufficient experience and insight have been accumulated to help finalize the design of the 0.6 MB/H experimental model. Fabrication of the 0.6 MB/H model in 33% complete. A Coal-Water Fuel (CWF) loop for firing tests and an apparatus for testing CWF nozzle spray patterns are also 33% complete. A now test facility which includes the flue gas cleaning facility (described in our first quarterly progress report) is operational. We are now able to conduct independent tests on both the 0.15 and 0.6 MB/H models without disruption to either model. Current efforts have been concentrated in permanently installing test apparatus/equipment in the now test facility area. CWF tests in the 0. 15 MB/H model and DUC tests in the 0. 6 MB/H model are expected to begin in September 1988.

The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full-scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO and NO emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintained at levels existing prior to LIMB retrofit, and (c) technical difficulties attributable to LIMB operation, such as additional slagging and fouling, changes in ash disposal requirements, and an increased particulate load, can be resolved in a cost-effective manner. The primary fuel to be used will be an Ohio bituminous coal having a nominal sulfur content of 3 percent or greater.

This report describes several new applications of laser-produced plasmas that have arisen in the last few years. Most of the applications have been an outgrowth of the active research in laser/matter interaction inspired by the pursuit of laser fusion. Unusual characteristics of high-intensity laser/matter interaction, such as intense x-ray and particle emission, were noticed early in the field and are now being employed in a significant variety of applications outside the fusion filed. Applications range from biology to materials science to pulsed-power control and particle accelerators. 92 refs., 23 figs., 4 tabs.

This study examines potential hazards to human health from the ingestion of chemicals in ground waters beneath and adjacent to four abandoned uranium mill-tailings sites: Gunnison, Colorado; Lakeview, Oregon; Monument Valley, Arizona; and Riverton, Wyoming. Chemicals of concern in the ground water near these sites include arsenic, cadmium, chromium, lead-210, molybdenum, nitrate, polonium-210, radium 226 and radium 228, selenium, sulfate, thorium-230, uranium and vanadium. Hazards to health were evaluated by implementing the method outlined in the Environmental Protection Agency's (EPA's) Superfund Public Health Evaluation Manual. Conservative assumptions in the method, and the effect of these on the risk estimates and EPA's indices of harm are discussed. Because the method has a number of built-in conservatisms, the estimated risks and indices only indicate sites and chemicals requiring further analysis. The chemicals and sites identified as presenting risk in this first screening step should be investigated in more detail. Necessary steps are given. Sites and chemicals identified as harmless in this initial screening can be eliminated from further consideration. 9 refs., 4 figs., 4 tabs.

Radiation detection surveys are used at the US Department of Energy's Hanford Reservation near Richland, Washington, to determine areas that need posting as radiation zones or to measure dose rates in the field. The relationship between measurements made by Sodium Iodide (NaI) detectors mounted on the mobile Road Monitor vehicle and those made by hand-held GM P-11 probes and Micro-R meters are of particular interest because the Road Monitor can survey land areas in much less time than hand-held detectors. Statistical regression methods are used here to develop simple equations to predict GM P-11 probe gross gamma count-per-minute (cpm) and Micro-R-Meter ..mu..R/h measurements on the basis of NaI gross gamma count-per-second (cps) measurements obtained using the Road Monitor. These equations were estimated using data collected near the 116-K-2 Trench in the 100-K area on the Hanford Reservation. Equations are also obtained for estimating upper and lower limits within which the GM P-11 or Micro-R-Meter measurement corresponding to a given NaI Road Monitor measurement at a new location is expected to fall with high probability. An equation and limits for predicting GM P-11 measurements on the basis of Micro-R- Meter measurements is also estimated. Also, we estimate an equation that may …

The basic physical processes associated with collisionless magnetic reconnection are investigated using the implicit PIC code AVANTI. The code is based on a 2.5-D fully electromagnetic direct implicit algorithm which has proven stable for arbitrary time step. This stability makes it possible to separate out the respective roles of the highly magnetized electrons and the un-magnetized ions for large ion-electron mass ratios. It is found that the inclusion of a guide magnetic field (magnetic shear) severely slows the initial stages of reconnection and damps out the electrostatic ringing if local values of the guide field are above a threshold determined by questions of electron mobility. 9 refs., 6 figs.
