Pyroprocessing was originally developed for the recycling of the metal fuel from a fast reactor. It was noted that pyroprocessing can be modified by an oxide reduction process enabling treatment of spent nuclear fuels from a commercial light water reactor (LWR) which is in an oxide form. Pyroprocessing treatment can reduce the volume, radioactivity, and heat load of the LWR spent fuels [1]. In ...

Reactor noise, caused both by the probabilistic nature of the fission chains and external reactivity noises, is one of the basic topics in nuclear science and engineering, both in theory and practice. Modeling reactor noise (and neutron flux fluctuation in general) is traditionally performed by two main approaches: the stochastic transport equation for the probability generating function and th...

This theoretical article investigates an industrial emulsion copolymerization of acrylonitrile (A) and butadiene (B), for the production of grades BJLT and AJLT of a nitrile rubber (NBR). The simulated process involves a train of eight continuous stirred-tank reactors operating at 10 ◦C. The product quality is determined by its molecular structure (average copolymer composition, average molecul...

Biological phosphorus removal (BPR) techniques offer a number of advantages over chemical addition, including enhanced treatment, reduced energy consumption, and reduced sludge production. A rapid, low-cost method for determining the feasibility of biological phosphorus removal should allow these techniques to be more widely used. A simple test is proposed to determine the amount of phosphorus ...

The aim of the paper was to introduce an algorithm by which a production method any complex liquid solution can be done using multistage plug flow reactor from “Innovative Engineering”. example given in is modified nutrition for Paulownia with increased sequestration potential carbon polygon environment. designed continuously mix liquids order create consistent up 7 components if only one used....

Despite their sustainability, the potential of biocatalytic processes in industrial production is far from being realized. The main challenges this field are development highly active, robust, and stable biocatalysts, efficient regeneration cofactors, prevention biocatalyst deactivation under harsh conditions. In addition to engineering, enzyme cell immobilization plays a crucial role process f...

Fusion and advanced fission power plants require nuclear materials to function under new, extreme environments. Understanding the evolution of mechanical functional properties during radiation damage is essential design commercial deployment these systems. The shortcomings existing methods could be addressed by a new technique - intermediate energy proton irradiation (IEPI) using beams 10–30 Me...
