“…It is being created by UOL (University of Liverpool). Simplified coupled reactor physics at the fuel assembly are delivered by the customized coupling software environment after transferring via itself the homogenized fuel assembly cross sections from the spectral code SCALE [36][37][38] to the nodal code DYN3D [39][40][41]. Improved coupled reactor physics at the fuel pin level are delivered by the customized coupling software environment either after transferring via itself the homogenized fuel pin cross sections from SCALE to DYN3D or after performing fuel pin power reconstruction in DYN3D.…”

Traditionally, the complex coupled physical phenomena in nuclear reactors has resulted in them being treated separately or, at most, simplistically coupled in between within nuclear codes. Currently, coupling software environments are allowing different types of coupling, modularizing the nuclear codes or multi-physics. Several multiscale and multi-physics software developments for LWR are incorporating these to deliver improved or full coupled reactor physics at the fuel pin level. An alternative multiscale and multi-physics nuclear software development between NURESIM and CASL is being created for the UK. The coupling between DYN3D nodal code and CTF subchannel code can be used to deliver improved coupled reactor physics at the fuel pin level. In the current journal article, the second part of the DYN3D and CTF coupling was carried out to analyse a parallel two-way coupling between these codes and, hence, the outer iterations necessary for convergence to deliver verified improved coupled reactor physics at the fuel pin level. This final verification shows that the DYN3D and CTF coupling delivers improved effective multiplication factors, fission, and feedback distributions due to the presence of crossflow and turbulent mixing.
