Numerical studies of stepwise radial fuel shuffling in a traveling wave reactor
Science China Technological Sciences, 2014The concept of travelling wave reactor (TWR) applies the mechanism of self-sustaining and propagating nuclear fission travelling waves in fertile media of 238U and 232Th to achieve very high fuel utilization. Based on this concept, a stepwise radial fuel shuffling strategy was proposed and applied to a sodium-cooled fast reactor (SFR) loading metallic ...

Study of traveling wave reactor (TWR) and CANDLE strategy: A review work
Progress in Nuclear Energy, 2014Abstract TWR applies the mechanism of self-sustainable and propagating nuclear fission traveling waves in fertile material. Natural uranium or depleted uranium can be used as fresh fuel to achieve very high burn-up without enrichment and reprocessing and TWR has been theoretically and numerically investigated due to these important merits. CANDLE ( C

Using SERPENT Monte Carlo and Burnup code to model Traveling Wave Reactors (TWR)
SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo, 2014This paper is mainly devoted to the proof-of-principle implementation of the SERPENT code for the simulation of traveling wave reactors. The investigation of SERPENT 1.1.19 code for multiprocessor tasks with long burnup steps was performed. The investigation of SERPENT 2 code for multiprocessor tasks with long burnup steps was performed.

Abstract An experimental study of axial temperature profiles in a nonadiabatic tubular fixed bed reactor has been made under the transient operation. The catalytic carbon monoxide oxidation occuring on a Pt/alumina catalyst has been used. Unlike the adiabatic conditions the velocity of a traveling temperature wave in a nonadiabatical arrangement ...
