Unclassified reports on processing of enriched UF₆ into U metal, U-base alloys, UO₂, and UO₂SO₄ for use a reactor fuels are annotated. Recovery of enriched U scrap, methods of isotopic analysis, health physics, criticality problems, and materials management are emphasized. A few references to papers presented at the Geneva Conference, 1955, and other recent nonreport literature are included. 254 references.

On February 18, 2011, Caterpillar Tractor Company, Inc. (CAT) was notified by the Woodford County Emergency Management Agency that residents along Ten Mile Creek had noticed a fuel odor. CAT personnel checked outfalls on the bluff below and the Proving Grounds fuel station and discovered some diesel fuel seeping into a ravine which continues to Ten Mile Creek. An initial investigation around the fueling facility revealed a diesel leak in an underground line that feeds the fuel dispensers. Diesel fuel is used on the Proving Grounds property to power the earth-moving equipment being tested there. At the time the leak was found, CAT began excavating to remove the source and to find the extend of the leak. The fuel had followed a down-hill slope to a ravine on CAT property, ran down the ravine and impacted Ten-Mile Creek (about one-half mile away) with a visible sheen of diesel fuel on top of the water.

The Illinois Environmental Protection Agency (Illinois EPA) was asked by the Illinois General Assembly to examine whether the State should address further potential restrictions on power plant pollution. This request was made under Section 9-10 of the Environmental Protection Act (Act). This is a report of the Illinois EPA's findings. The Illinois EPA has prepared this report of its findings to date based on consideration of a broad spectrum of issues including health benefits, the impact of the reliability of the power grid, the impact on consumer utility rates and the impact on jobs and Illinois' economy. It provides an overview of the principal issues, presents a review of the information we have gathered that addresses those issues, lists information gaps, and uncertainties and finally, lists the work that remains to develop a solution that does not create unintended adverse economic consequences for the people of Illinois.

Diesel trucks and buses account for approximately 50 percent of the particulate matter (PM) and oxides of nitrogen (NOx) air pollution from on-road vehicles in Illinois. PM and NOx may contribute to a variety of health effects, including nausea, headaches, increased risk of asthma attacks, lung cancer, and premature death. Children and people with lung and heart conditions, are generally the most sensitive to diesel exhaust. Millions of tons of air pollution are emitted every year in the U.S. by trucks and buses that idle while parked.

The operation of polymer electrolyte membrane fuel cells (PEMFCs) with dry feeds has been examined with different fuel cell flow channel designs as functions of pressure, temperature and flow rate. Auto-humidified (or self-humidifying) PEMFC operation is improved at higher pressures and low gas velocities where axial dispersion enhances back-mixing of the product water with the dry feed. We demonstrate auto-humidified operation of the channel-less, self-draining fuel cell, based on a stirred tank reactor; data is presented showing auto-humidified operation from 25 to 115 degrees C at 1 and 3 atm. Design and operating requirements are derived for the auto-humidified operation of the channel-less, self-draining fuel cell. The auto-humidified self-draining fuel cell outperforms a fully humidified serpentine flow channel fuel cell at high current densities. The new design offers substantial benefits for simplicity of operation and control including: the ability to self-drain reducing flooding, the ability to uniformly disperse water removing current gradients and the ability to operate on dry feeds eliminating the need for humidifiers. Additionally, the design lends itself well to a modular design concept. (c) 2005 Elsevier B.V. All rights reserved.
