Sorption and chemical transformation of PAH`s on coal fly ash (open access)

Sorption and chemical transformation of PAH`s on coal fly ash

The major objective of this work was to characterize the interactions of coal fly ash with polycyclic aromatic hydrocarbons (PAHS) and their derivatives, and to attempt to understand the influence of the surface properties of coal ash (and other atmospheric particles) on the chemical transformations of polycyclic aromatic compounds. Our studies have concentrated on the photochemical behavior of PAHs sorbed form the vapor phase on coal fly ashes, and compositional subfractions obtained therefrom. The PAHs are deposited onto the fly ash substrates from the vapor phase, using apparatus and techniques developed in this laboratory in order to simulate, as closely as possible under laboratory conditions, the processes by which PAHs deposit onto fly ash particles in the atmosphere. In this report phototransformation of pyrene sorbed on fly ash fractions, and phototransformations of 1-nitropyrene sorbed on fly ash fractions are discussed.

Effects of ethanol on small engines and the environment (open access)

Effects of ethanol on small engines and the environment

With the support of the Missouri Corn Merchandising Council and the Department of Energy, Northwest Missouri State University conducted an applied research project to investigate the effects of the commercially available ethanol/gasoline fuel blend on small engines. The study attempted to identify any problems when using the 10% ethanol/gasoline blend in engines designed for gasoline and provide solutions to the problems identified. Fuel economy, maximum power, internal component wear, exhaust emissions and engine efficiency were studied.

Position paper: Live load design criteria for Project W-236A Multi-Function Waste Tank Facility (open access)

Position paper: Live load design criteria for Project W-236A Multi-Function Waste Tank Facility

The purpose of this paper is to discuss the live loads applied to the underground storage tanks of the Multi Function Waste Tank Facility, and to provide the basis for Project W-236A live load criteria. Project 236A provides encompasses building a Weather Enclosure over the two underground storage tanks at the 200-West area. According to the Material Handling Study, the Groves AT 1100 crane used within the Weather Enclosure will have a gross vehicle weight of 66.5 tons. Therefore, a 100-ton concentrated live load is being used for the planning of the construction of the Weather Enclosure.

Feasibility of organo-beryllium target mandrels using organo-germanium PECVD as a surrogate (open access)

Feasibility of organo-beryllium target mandrels using organo-germanium PECVD as a surrogate

Inertial Confinement Fusion capsules incorporating beryllium are becoming attractive for use in implosion experiments designed for modest energy gain. This paper explores the feasibility of chemical vapor deposition of organo-beryllium precursors to form coating materials of interest as ablators and fuel containers. Experiments were performed in a surrogate chemical system utilizing tetramethylgermane as the organometallic precursor. Coatings with up to 60 mole percent germanium were obtained. These coatings compare favorably with those previously reported in the literature and provide increasing confidence that a similar deposition process with an organo-beryllium precursor would be successful.

105-KE Basin isolation barrier leak rate test analytical development. Revision 1 (open access)

105-KE Basin isolation barrier leak rate test analytical development. Revision 1

This document provides an analytical development in support of the proposed leak rate test of the 105-KE Basin. The analytical basis upon which the K-basin leak test results will be used to determine the basin leakage rates is developed in this report. The leakage of the K-Basin isolation barriers under postulated accident conditions will be determined from the test results. There are two fundamental flow regimes that may exist in the postulated K-Basin leakage: viscous laminar and turbulent flow. An analytical development is presented for each flow regime. The basic geometry and nomenclature of the postulated leak paths are denoted.

Dose rate estimates in the first optical enclosure due to particle beam loss in the insertion device transition region during injection (open access)

Dose rate estimates in the first optical enclosure due to particle beam loss in the insertion device transition region during injection

The particle beam, during injection into the storage ring, can be partly lost in one of the transition regions between the storage-ring vacuum chamber and the insertion-device (ID) straight section. The transition region is a copper interface between a standard aluminum vacuum chamber and an insertion-device vacuum chamber. This can be a problem, at least in the first few insertion devices where the injected beam is still unstable. It may create higher photon and neutron dose rates in the first optical enclosures of the upstream ID beamlines adjacent to this region. This report presents the results of the dose rate estimates for such an event and some recommendations for mitigation.
