Multi-physics Codes for Safety and Dynamics of Nuclear Systems

Codes developed by KIT/TRANS

• COUPLE fast running analyses for core layout and operational conditions
• KIN3D neutron kinetics model for ultrashort transients in subcritical systems included in ERANOS
• KORIGEN and C4P/TRAIN used for long-term phenomena, burn-up, radioactive decay, decay heat, radio-toxicity, preparation of cross-sections

Codes, where KIT/TRANS contributes to development

• PARTISN code for neutron transport, coupled to SIMMER
• SIMMER-III/IV codes for simulation of severe accidents for GEN-IV reactors

Other codes used

• ERANOS, MCNP deterministic codes for neutron transport
