Static Benchmarks for G4-STORK, a Time-Evolution Monte Carlo Code for the Simulation of Multiplying Media

Abstract

The GEANT-4 toolkit was used to develop G4-STORK, which allows one to study the timedevelopment of a neutron population in a multiplying media such as a nuclear reactor core. The code has a number of additional attractive features such as on-the-fly Doppler broadening, modification of material properties during a run, “real-time” treatment of delayed neutrons, 3-D representation of the geometry including particle tracks, and the ability to track particles in a magnetic field. The GEANT-4 toolkit has parallel processing options and the capability of importing and exporting geometries to CAD programs. This paper gives the current status of the G4-STORK project, including static applications to a SLOWPOKE and the SCWR conceptual design.
