Ongoing engineering design studies at Oak Ridge National Laboratory are exploring the feasibility of converting the High Flux Isotope Reactor (HFIR) from highly enriched uranium (HEU) to low-enriched uranium (LEU) fuel. HFIR is a pressurized light water-cooled and moderated research ... En savoir plus

Ultrasonic flow-cell reactors are used for many industrial applications, where fluid substrate is sonicated in a small region, where very high ultrasonic acoustic power is present. The electromechanical transducer (converter) that drive the sonotrode inside the flow-cell is designed in ... En savoir plus

Mist chemical vapor deposition (mist-CVD) has recently attracted interest as a facile, cost-effective, and environmentally friendly method for depositing thin films of various materials. In this method, mist droplets containing the reactant solution are injected into the reactor and ... En savoir plus

Many industrial processes involving chemical reactions rely on heat addition, which accounts for approximately 50% of all energy consumed in the United States' industrial sector. Examples include metallurgical processes, chemical processing, and heating process fluids. Traditionally, ... En savoir plus

In the nuclear fuel industry, the dry conversion process is employed to transform crystalline UF6 to UO2 powder, in order to produce fuel pellets. The quality of the finished product highly depends on the process input parameters, and it is imperative to understand accurately the full ... En savoir plus

The transition to sustainable production includes the reduction of fossil material usage. Vegetable oil can be used as a reagent to form polyurethane by epoxidation through three major reaction steps, epoxidation, carbonation, and aminolysis. Many attempts have been made to model these ... En savoir plus

Integrating exothermic and endothermic reactions within a single reactor offers a promising strategy to enhance overall thermal efficiency. However, existing systems often suffer from limited heat transfer performance due to design and heat transfer constraints. To overcome this ... En savoir plus

The reversible storage of hydrogen in metal hydrides represents an attractive technology for hydrogen-based energy systems. In addition to their application as pure hydrogen storage media, metal hydrides can also be used to develop thermochemical hydrogen compressors, which can be ... En savoir plus

Induction heating (IH) [1] is a good candidate for decarbonization of chemical processes: energy savings, process intensification and production costs reduction [2-5]. Heat can be generated directly into the reactor at the surface in contact with the gas flux passing through a specific ... En savoir plus

The significance of electrification of industry increases with the growing influence of renewable electricity as a primary energy source on earth. In this sense, microwave heating is a well-established electricity-based and market-mature technology employed on the commercial scale in ... En savoir plus
