We have developed a self-consistent integrated modelling of core and SOL/divertor transport, i.e. a 1.5D core code TOPICS-IB and a 2D divertor code SONIC have been successfully coupled. The dynamic simulations are carried out for JT-60SA with this integrated code including a CDBM transport model, where particle and heat transports are suppressed by the EB shearing effect. The L/H transition is successfully demonstrated based on the turbulent suppression transport model and the self-consistent boundary condition. It is interesting to note that the fluctuating nature appears in the divertor plasma after the transition.
