We have developed a self-consistent integrated modelling of core and SOL/divertor transport. Thereby it enables us to investigate operation scenarios to be compatible with high confinement core plasma and detached divertor plasmas. A 1.5D core code TOPICS-IB and a 2D divertor code SONIC were coupled successively with a Multiple Program Multiple Data parallel computing system. For an integrated code including Monte-Carlo calculations, this system makes it possible to perform efficient simulations. The dynamic simulation for the L/H transition in JT-60SA is carried out by this integrated code with a CDBM transport model including the EB shearing effect. Impacts of SOL/divertor transport on the L/H transition is studied.
