Progress in heavy-ion drivers for inertial fusion (open access)

Progress in heavy-ion drivers for inertial fusion

Heavy-ion induction accelerators are being developed as fusion drivers for ICF power production in the US Inertial Fusion Energy (IFE) program, in the Office of Fusion Energy of the US Department of Energy. In addition, they represent an attractive driver option for a high-yield microfusion facility for defense research. This paper describes recent progress in induction drivers for Heavy-Ion Fusion (HIF), and plans for future work. It presents research aimed at developing drivers having reduced cost and size, specifically advanced induction linacs and recirculating induction accelerators (recirculators). The goals and design of the Elise accelerator being built at Lawrence Berkeley Laboratory (LBL), as the first stage of the ILSE (Induction Linac Systems Experiments) program, are described. Elise will accelerate, for the first time, space-charge-dominated ion beams which are of full driver scale in line-charge density and diameter. Elise will be a platform on which the critical beam manipulations of the induction approach can be explored. An experimental program at Lawrence Livermore National Laboratory (LLNL) exploring the recirculator principle on a small scale is described in some detail; it is expected that these studies will result ultimately in an operational prototype recirculating induction accelerator. In addition, other elements of the US …

Progress toward uranium scrap recycling via Electron Cold Hearth Refining (EBCHR) (open access)

Progress toward uranium scrap recycling via Electron Cold Hearth Refining (EBCHR)

A 250 kW electron beam cold hearth refining (EBCHR) melt furnace at Lawrence Livermore National Laboratory (LLNL) has been in operation for over a year producing 5.5 in.-diameter ingots of various uranium alloys. Production of in-specification uranium-6% - niobium (U-6Nb) alloy ingots has been demonstrated using virgin feedstock. A vibratory scrap feeder has been installed on the system and the ability to recycle chopped U-6Nb scrap has been established. A preliminary comparison of vacuum arc remelted (VAR) and electron beam (EB) melted product is presented.

F-Area Acid/Caustic Basin Groundwater Monitoring Report. Fourth Quarter 1994, Groundwater Monitoring Report (open access)

F-Area Acid/Caustic Basin Groundwater Monitoring Report. Fourth Quarter 1994, Groundwater Monitoring Report

During fourth quarter 1994, samples from the FAC monitoring wells at the F-Area Acid/Caustic Basin were collected and analyzed for herbicides/pesticides, indicator parameters, metals, nitrate, radionuclide indicators, volatile organic compounds, and other constituents. Piezometer FAC 5P was dry and could not be sampled. New monitoring wells FAC 9C, 10C, 11C, and 12C were sampled for the first time during third quarter.

Nondestructive testing of ceramic components: Cooperative research and development agreement completion report (open access)

Nondestructive testing of ceramic components: Cooperative research and development agreement completion report

In a joint Cooperative Research and Development Agreement (CRADA) between Martin Marietta Energy Systems (MMES) and an industrial partner, Y-12 has been evaluating nondestructive evaluation (NDE) techniques to identify the quality of high strength aluminum oxide tubes used in laser applications. In Phase I, several NDE techniques were developed to inspect the tubes. In Phase II a correlation between detected defects, actual failure mode and strength of the tubes was developed. In Phase II the industrial partner supplied tubes manufactured under a variety of conditions and containing material defects expected from process control variations. The tubes were inspected at MMES utilizing a variety of available acoustic techniques. After inspection, ring tensile specimens were fabricated to determine the tensile strength. The data were evaluated utilizing Weibull statistics to determine the statistical impact of the defects upon strength and correlate the data with the nondestructive evaluations of the tubes and observed defect distribution.

Inductive Double-Contingency Analysis of UO2 Powder Bulk Blending Operations at a Commercial Fuel Plant (U) (open access)

Inductive Double-Contingency Analysis of UO2 Powder Bulk Blending Operations at a Commercial Fuel Plant (U)

An inductive double-contingency analysis (DCA) method developed by the criticality safety function at the Savannah River Site, was applied in Criticality Safety Evaluations (CSEs) of five major plant process systems at the Westinghouse Electric Corporation`s Commercial Nuclear Fuel Manufacturing Plant in Columbia, South Carolina (WEC-Cola.). The method emphasizes a thorough evaluation of the controls intended to provide barriers against criticality for postulated initiating events, and has been demonstrated effective at identifying common mode failure potential and interdependence among multiple controls. A description of the method and an example of its application is provided.

Marshak waves: Constant flux vs constant T-a (slight) paradigm shift

We review the basic scaling laws for Marshak waves and point out the differences in results for wall loss, albedo, and Marshak depth when a constant absorbed flux is considered as opposed to a constant absorbed temperature. Comparisons with LASNEX simulations and with data are presented that imply that a constant absorbed flux is a more appropriate boundary condition.

Documentation concerning KKP development work (open access)

Documentation concerning KKP development work

Fabrication has been completed on a 16 level KPP on a 5-inch diameter aperture fused silica using lithographic techniques and wet etching of fused silica in a buffered hydrofluoric acid solution. The experimentally measured far-field intensity pattern displays the desired top-hat envelope and has a superimposed speckle on it. The far-field contains 90% of the incident energy inside the 640 {mu}m region. This is a significant improvement over the binary RPP`s in terms of the far-field profile control and energy concentration. Sources contributing to the energy loss are identified and efforts are underway to overcome these limitations.

Project W-236A multi-function waste tank facility waste feed projections

A review of Hanford Underground Waste Storage Tank Chemistry, coupled with planned remediation actions and retrieval sequences was conducted in order to predict the chemistry of the waste to be stored in the MWTF tanks. All projected waste solutions to be transferred to the MWTF tanks were found to be in compliance with current tank chemistry specifications; therefore, the waste and the tank materials of construction are expected to be compatible.
