Fabricating vanadium sheet to improve symmetry of drawn parts

Description: The degree of anisotropy in vanadium sheet determines the amount of earing in formed parts and relates to the roundness of the formed part. Experiments with annealing and rolling practices to produce vanadium sheet were undertaken to reduce the earing tendencies of the metal. Earing in formed vanadium hemishells was reduced by cross rolling; and for unidirectionally rolled sheet, increased reduction per rolling pass and proper selection of intermediate annealing temperature reduced the earing. … more

The reaction of synthetic nuclear waste glass in steam and hydrothermal solution

Description: Glass monoliths of the WVCM 44, WVCM 50, SRL 165, and SRL 202 compositions were reacted in steam and in hydrothermal liquid at 200{degree}C. The glass reaction resulted in the formation of leached surface layers in both environments. The reaction in steam proceeds at a very low rate until precipitates form, after which the glass reaction proceeds at a greater rate. Precipitates were formed on all glass types reacted in steam. The assemblage of phases formed was unique to each glass type, but se… more

The kinetics of sulfation of calcium oxide

Description: Studies of the sulfation rate behavior show an initial fast rate followed by a rate decrease. This behavior has generally been interpreted as product layer diffusion limitations taking over after an initial kinetic rate regime. Many investigators tried to model this observed rate change. As pore diffusion was a limiting phenomenon in most of the experiments, authors have used several pore models to described this complication, more or less successfully. Product layer diffusivity has been assume… more

Development and application of a mathematical model for the benzene stripping columns in the In-Tank Precipitation (ITP) process

Description: A mathematical model characterizing the operation of the benzene stripping columns in the In-Tank Precipitation (ITP) process has been developed. The model was verified using operations data of two stripping columns, and the model predicted reasonable, conservative values of the height of a transfer unit (HTU) and outlet solute concentrations. The model was applied to predict general operating efficiency of the ITP strippers, and predictions indicate that the stripping columns will be able to s… more

An Economic Impact Analysis of the Proposed Yakima/Klickitat Fishery Enhancement Project; Preliminary Design Report, Appendix D.

Description: The objective of this study is to estimate the economic impact of the proposed Yakima/Klickitat Production Project on the local economies of the Yakima and Klickitat subbasins. The project, when operating at planned maximum production, will augment the total number of salmon and steelhead returning to the subbasins by 77,600 and will increase the sustainable terminal harvest by 55,160. These estimates do not include fish harvested in the ocean or in the mainstem Columbia. In addition to evaluat… more

Novel supports for coal liquefaction catalysts

Description: Cold model studies of the liquid fluidized bed microreactor are essentially complete. This report documents experimental data obtained for the optimum (60{degrees} blade angle) axial flow impeller in Gas/Liquid/Solid service. Dimensionless correlations are presented for the critical stirrer speeds corresponding to incipient fluidization, S{sub 1}, and particle carryover, S{sub 2}. Under some circumstances bed expansion ceases prior to particle carryover due to cavitation in the impeller. A corr… more

Hydrothermal pretreatment of coal

Description: We have examined changes in Argonne Premium samples of Wyodak coal following 30 min treatment in liquid water at autogenous pressures at 150{degrees}, 250{degrees}, and 350{degrees}C. In most runs the coal was initially dried at 60{degrees}C/1 torr/20 hr. The changes were monitored by pyrolysis field ionization mass spectrometry (py-FIMS) operating at 2.5{degrees}C/min from ambient to 500{degrees}C. We recorded the volatility patterns of the coal tars evolved over that temperature range, and in… more

Numerical error in electron orbits with large. omega. sub ce. delta. t

Description: We have found that running electrostatic particle codes relatively large {omega}{sub ce}{Delta}t in some circumstances does not significantly affect the physical results. We first present results from a single particle mover finding the correct first order drifts for large {omega}{sub ce}{Delta}t. We then characterize the numerical orbit of the Boris algorithm for rotation when {omega}{sub ce}{Delta}t {much gt} 1. Next, an analysis of the guiding center motion is given showing why the first ord… more

Configuring the SLC linac for injection into PEP

Description: From time to time the normal SLC physics program is to be interrupted so that beam can be delivered to PEP. In order that the switch to PEP injection (and the switch back again) can be accomplished quickly and easily, the gun, the damping rings, the linac phase ramp, the energy profile of the linac klystrons for the scavenger bunch, and the entire positron production system are to be kept the same as in the SLC configuration. What mainly remains to be changed is the linac klystron profile for t… more

Final summary report for 1989 inservice inspection (ISI) of SRS (Savannah River Site) 100-P Reactor tank

Description: The integrity of the SRS reactor tanks is a key factor affecting their suitability for continued service since, unlike the external piping system and components, the tanks are virtually irreplaceable. Cracking in various areas of the process water piping systems has occurred beginning in 1960 as a result of several degradation mechanisms, chiefly intergranular stress corrosion cracking (IGSCC) and chloride-induced transgranular cracking. IGSCC, currently the primary degradation mechanism, also … more
