Shape Optimization of Inlet Plenum in a PBMR-Type Gas-Cooled Nuclear Reactor

Effects of Furnace and Inlet Gas Mixture Temperature on Growing Carbon Nanotube in a CVD Reactor

Carbon nanotubes (CNTs), nowadays, are one of the important nanomaterials that can be produce with different methods such as chemical vapor deposition (CVD). Growing of CNTs via CVD method can be influenced by several operating parameters that can affect their quality and quantity. In this article, the effects of inlet gas mixture temperature on CNT’s local growth rate, total production, and le...

Experimental Approach to Flow Field Evaluation in Upper Plenum of Reactor Vessel for Innovative Sodium Cooled Fast Reactor

In Japan Atomic Energy Agency, an innovative sodium cooled fast reactor of 1500MWe class, JSFR, has been investigated on the Fast Reactor Cycle Technology Development project. A compact reactor vessel (R/V) and a column type upper inner structure with a radial slit for an arm of a fuel-handling machine are adopted. These result in increase of the spatial-averaged velocity on the horizontal cros...

Dynamic optimization of a gas-liquid reactor

A dynamic gas-liquid transfer model without chemical reaction based on unsteady film theory is considered. In this case, the mathematical model presented for gas-liquid mass-transfer processes is based on mass balances of the transferred substance in both phases. The identificability property of this model is studied in order to confirm the possible identifiable parameters of the model from a g...
