Redox flow batteries (RFBs) have the potential for economical storage of electrical energy than other battery chemistries. They use high-cost ion exchange membranes as separators between anolyte and catholyte, which prevent broad market penetration. Proton exchange membranes (e.g., Nafion) are poorly selective, allowing undesired cross-diffusion of active species in solution electrolytes across t ...

THE PROPOSED RESEARCH IS TO ADVANCE THE STATE-OF-THE-ART OF DETERMINISTIC RISK ANALYSIS AND FIRE PROTECTION METHODOLOGY OF NUCLEAR POWER PLANTS. A COMPUTER CODE, BASED ON THE USE OF A FIELD (DISCRETIZATION) MODELING TECHNIQUE, WILL BE DEVELOPED THAT HAS SUFFICIENT FLEXIBILITY FOR ACCURATE/REALISTIC REPRESENTATIONS OF GEOMETRY, VENTILATION AND OTHER CONDITIONS PRESENT IN CABLE ROOMS AND CONTROL ROO ...

Abstract Ion cyclotron range of frequency (ICRF) power is anticipated to be a primary auxiliary heating source in next step tokamak experiments like ITER. From a technological perspective, electrical breakdown is a significant challenge for ICRF utilization in present experiments and will become more challenging for future devices like ITER and other reactors. An ICRF system utilizes an antenna to ...

This Small Business Technology Transfer (STTR) Phase 1 project will lead to the development of a simple, cost effective technology which can recover helium from gas reservoirs containing helium concentrations too low to permit economic recovery at present. This will enable helium recovery from fields currently producing natural gas but considered uneconomical for the recovery of the contained heli ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

A STEAMFLOODING/STEAM GENERATION SYSTEM IS PROPOSED FOR DEEP, HEAVY OIL RESERVOIRS. THIS CONCEPT MINIMIZES THE DOWNHOLE HEAT LOSSES, IMPROVES RELIABILITY AND REDUCES THE COST OF STEAM GENERATION. ITS FEATURES WILL MAKE STEAMING OF VERY DEEP WELLS (BELOW 7500 FEET) TECHNICALLY AND ECONOMICALLY FEASIBLE, AND WILL IMPROVE THE ECONOMICS OF SHALLOWER WELL STEAMFLOODING. THIS NOVEL CONCEPT SUPPLIES HEAT ...

TO ACHIEVE PRECISE SHAPING OF DENSITY PROFILES IN FUSION REACTORS WITH PELLET FUELING, INJECTION VELOCITIES OF UP TO 10 KM/SEC MAY BE REQUIRED FOR PELLETS OF A FEW MILLIGRAMS IN MASS. PRESENT PELLET INJECTORS BASED ON THE PNEUMATIC GUN OR CENTRIFUGE PRINCIPLES ARE CAPABLE OF ATTAINING VELOCITIES OF ABOUT 2 KM/SEC, AND THE BASIC CONCEPTS DO NOT APPEAR TO BE EASILY SCALABLE TO HIGHER PERFORMANCES. A ...

Increased use of hydrogen as a fuel can provide benefits to our nations energy security, the environment and economic growth. Toward hydrogen economy, an innovation in hydrogen separation technology is needed in the production of hydrogen. Current separation technologies for industrial hydrogen production mainly include pressure swing adsorption process and the cryogenic separation process, which ...
