Nuclear reactions at low and intermediate energies

Oral

Understanding and predicting the dynamic behaviour of nuclear reactors is of paramount importance for reactor safety. This time-dependent behaviour is primarily driven by the emission of beta-delayed neutrons and photoneutrons following the decay of neutron-rich fission products. It is the production of these delayed neutrons which allows for a system-dependent “sluggishness” during power...

Energy applications

Oral

Acceletator driven system (ADS) is simulated by the Geant4 tools - the mass layered geometry and scoring. The ADS target was simulated with different geometries of cooling layers. The neutron output spectra as well as energy deposition profiles are shown. The ADS power (and other parameters) dependence on driver thickness are shown. The medical isotope production is simulated in the batch mode...

60. Adaptation of GEANT-4 to Criticality Calculations for Nuclear Reactors

Energy applications

Oral

GEANT-4 is well suited for criticality calculations in nuclear reactors, thanks to its ability to track particles, in this case neutrons, in time as well as in space. This sets it apart from traditional Monte Carlo codes such as MCNP, which treat neutrons on a generation-by-generation base. The latter gives inherently incorrect results, in particular for systems that are far from critical. ...
