Computer-based simulations of fossil fuel processing plants can help make significant improvements to plant efficiency, as well as with procedures to reduce emissions, e.g. of CO2. The Barracuda engineering software is in wide spread usage for such applications at DOE Labs and with industry because of its demonstrated success for high-fidelity predictions of the multiphase flows. Simulation of the ...

The strontium-82/rubidium-82 biomedical generator (brandname Cardiogen) provides a radioactive, positron emitting tomography (PET) isotope, used for myocardial perfusion imaging. The only indigenous, US, manufacturers of active pharmaceutical ingredient (API) grade strontium-82(Sr-82) parent material are Los Alamos (LANL) and Brookhaven National Laboratories (BNL). Manhattan Isotope Technology h ...

ELECTRO-DEPOSITION OF SILICON FILMS FROM LIQUID-METAL SOLUTIONS WILL BE INVESTIGATED. THE OBJECTIVE IS TO DEVELOP A LOW-COST PROCESS FOR THE PRODUCTION OF HIGH-EFFICIENCY THIN-FILM PHOTOVOLTAIC DEVICES. SPECIFICALLY, CURRENT-CONTROLLED GROWTH OF A SILICON FILM ON A SUBSTRATE IS ACCOMPLISHED USING A LIQUID-METAL SOLUTION, SUCH AS TIN, AND A SILICON SOURCE ELECTRODE. THE QUALITY OF SILICON GROWN FRO ...

HIGH POWER TRANSIT-TIME AMPLIFIERS ARE A NEW CLASS OF RF SOURCE THAT CONVERTS THE KINETIC ENERGY OF AN ELECTRON BEAM INTO RF RADIATION IN A VERY EFFICIENT WAY. WHEN THE BEAM CROSSES THE CAVITY OF PROPER DIMENSIONS, IT WILL INTERACT WITH A SINGLE CAVITY MODE THEREBY RADIATING COHERENTLY AT THE MODE'S FREQUENCY. MODE GROWTH CONTINUES UNABATED UNTIL THE RF FIELDS ARE LARGE ENOUGH TO MODIFY THE BEAM O ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

THE OBJECTIVE OF OUR PROJECT IS TO DEVELOP NEW MEANS OF PRODUCING SHORT LIVED RADIOISOTOPES FOR POSITRON EMISSION TOMOGRAPHY (PET). THIS MEDICAL DIAGNOSTIC TECHNIQUE IS CAPABLE OF DISCERNING AND IMAGING MEDICALLY INTERESTING PHENOMENA, SUCH AS THE ACTIVITY OF VARIOUS PARTS OF THE BRAIN, OXYGEN FLOW IN THE BODY, AND OTHER QUANTITIES WHICH ARE IMPOSSIBLE TO DETERMINE BY ANY OTHER DIAGNOSTIC TECHNIQU ...

METHANE PLAYS AN IMPORTANT ROLE IN THE CHEMISTRY OF BOTH THETROPOSPHERE AND STRATOSPHERE, AND ITS INCREASING CONCENTRATION MAY HAVE IMPORTANT EFFECTS ON THE GLOBAL ENVIRONMENT. THE DEVELOPMENT OF IMPROVED LOW COST INSTRUMENTATION FOR REAL-TIME MEASUREMENT OF METHANE FLUXES IS CRUCIAL TO CHARACTERIZING THE SOURCES AND SINKS OF THIS IMPORTANT ATMOSPHERIC SPECIES. THIS PROJECT WILL DEVELOP NEW INSTRU ...

WE DESCRIBE A NOVEL LEAK DETECTOR FOR XENON THAT HAS DIRECT APPLICATION TO TESTING RADIO-ISOTOPE-POWERED THERMOELECTRIC GENERATORS. SUCCESSFUL DEMONSTRATION OF OUR INNOVATION WILL ALLOW IMPROVED EFFICIENCY IN THERMOELECTRIC GENERATORS BY REMOVING THE HELIUM THAT IS NOW ADDED TO THE XENON BUFFERGAS FOR LEAK CHECKING PURPOSES. THE PHASE I RESEARCH PROGRAM WILL PROVIDE THE CRITICAL DESIGN INFORMATION ...
