Study on Neutronics Design of an Accelerator Driven Subcritical Reactor

Thorium fueled Accelerator Driven Subcritical Reactors
have been proposed as a more comprehensive alternative
to conventional nuclear reactors for both energy production
and for burning radioactive waste. Several new classes
have been added by the authors to the GEANT4 simulation
code, an extension which allows the state-of-the-art
code to be used for the first time for nuclear reactor criticality
calculations. In this paper we investigate the impact
of the subcriticality and injected proton beam energy on
the ADSR performance for novel ADSR configurations involving
multiple accelerator drivers and associated neutron
spallation targets within the reactor core.
