CORONA code

KAERI has been developing the CORONA code (Tak et al., 2014) for a core thermo-fluid analysis of a prismatic VHTR. The CORONA code is targeted for a whole core thermo-fluid analysis of a prismatic VHTR with fast computation and reasonable accuracy. The computational efficiency was achieved by combining the 3-D sohd heat conduction with a one-dimensional fluid flow network and adopting a block-wise parallel computation.

For a high fidehty core multiphysics analysis, KAERI has been developing a coupled code system using DeCART and CORONA (Lee et al., 2012a,b). DeCART transfers the power density and the fast neutron fluence to CORONA. On the other hand, CORONA transfers the temperature to DeCART. A separate computer code named CDECCO was developed for communication between DeCART and CORONA. No mapping is required in this coupled code system because the two codes use the same stmcture of the computational grids.
