Reactor design is an iterative process among various disciplines such as reactor physics, thermal fluid dynamics, mechanics, reactor and plant dynamics, fuel behavior, and instrumentation and control, and requires a wide range of modeling and simulation tools that can accurately predict key system performance and safety characteristics. Most code systems for fast reactor design were initiated m...

In some nuclear reactors the core is cooled by means of liquid metal alloy, for example, lead-bismuth eutectic alloy. For safety and licensing reasons, an imaging method for evaluation of status of the interior of reactor has thus to be developed. There are no any other physical means except ultrasonic, which would enable to inspect inner reactor parts submerged in the opaque hot liquid metal. ...

This work investigated the steady state and dynamic simulation of a fixed bed industrial naphtha reforming reactors. The performance of the reactor was investigated using a heterogeneous model. For process simulation, the differential equations are solved using the 4th order Runge-Kutta method .The models were validated against measured process data of an existing naphtha reforming plant. The r...
