The production of prismatic dislocation loops in nuclear reactor core materials results hardening because the impede motion. Yielding often occurs by a localised clearing through interactions with gliding dislocations called channeling. cleared channels represent softer material within which most subsequent deformation is localized. Channeling associated hypothetical pileup and intergranular cr...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...

Recent advances in supercomputers and parallel solver techniques have enabled users to run large simulations problems using millions of processors. Techniques for multiphysics nuclear reactor core simulations are under active development in several countries. Most of these techniques require large unstructured meshes that can be hard to generate in a standalone desktop computers because of high...

This study investigates the anaerobic treatability of reactive Red2 in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaerob...
