Recent neutronics developments for reactor safety studies with SIMMER code at KIT

Rineiski, A.; Marchetti, M.; Andriolo, L.; Gabrielli, F.

Abstract:
The SIMMER family of codes is applied for safety studies of sodium fast reactors and reactors of other types. Both neutronics and fluid-dynamics parts of SIMMER are under development. In the paper new neutronics capabilities are presented. In particular developments for neutron transport solvers and a new technique for taking into account thermal expansion effects are described. These new capabilities facilitate 3D simulations and improve accuracy of modelling for the initiation transient phase during a hypothetical severe accident.
