Although the purchase price of cellulosic feedstocks is competitive with petroleum on an energy basis, the cost of lignocellulose conversion to ethanol using today's technology is high. Cost reductions can be pursued via either in-paradigm or new-paradigm innovation. As an example of new-paradigm innovation, consolidated bioprocessing using thermophilic bacteria combined with milling during fer...
With growing demands for commercial nuclear power, there is also a growing need for better energy efficiency from nuclear power reactors. In order to reach a high burnup up to 100 MWd/kg, previous research has examined the use of thorium-plutonium mixedoxide fuel as a potential candidate for this high-burnup goal. Though the neutronics studies have looked upon this fuel type favorably, the purp...
Like for any power plant, refuelling will be one key issue in a future fusion reactor. It has to safe and efficient; due the operational principle, it also needs occur steady state. From previous investigations, became clear that injection of pellets - mm-size solid bodies produced from frozen fuel – is only possible technically realistic solution this task. Beyond their capability fuelling, ha...
The nuclear reactors themselves are complex systems whose responses driven by interactions between different physics phenomena within the reactor core. Traditionally, have been analyzed separately and its interaction considered via boundary conditions or closure models. However, in parallel with development of computational technology, multi-physics coupled simulations being used to obtain accu...
