The model of the pseudo-homogeneous, one-dimensional, cooled tubular reactor is applied to two consecutive, irreversible first order reactions. A criterion is derived to obtain a desired integral yield. Based on this criterion three requirements are formulated, which enable us to choose the relevant design and operating conditions. If any of the requirements are met, the reactor is also safe wi...

The use of heavy liquid metals, and especially of lead-bismuth eutectic (LBE) or lead for accelerator-driven systems (ADS) and lead-cooled (Pb) or lead-alloy-cooled (primarily Pb-Bi) fast reactor (FR) concepts of Generation IV requires an assessment of their compatibility with structural materials. Their deployment requires that the materials compatibility issue will be resolved, with and witho...

A High Temperature Gas-cooled Reactor (HTGR) is one of the renewed reactor designs to play a role in nuclear power generation. This reactor design concept is currently under consideration and development worldwide. The combination of coated particle fuel, inert helium gas as coolant and graphite moderated reactor makes possible to operate at high temperature yielding a high efficiency. In this ...

A design window concept is developed for a He-cooled fusion reactor blanket and divertor design. This concept allows study of a parameter regime under which a possible design exists with different design requirements, such as allowable pumping fraction. The concept identifies not only the required parameter regime, but also investigates the robustness of the design, i.e., the validity of the de...
