DOIAbstract
JT-60SA high-beta steady-state scenario at 2.3MA, 1.7T with 30 MW and 17 MW of NBI heating, respectively, and 7 MW of ECRH power has been investigated with the integrated suite of core / SOL / divertor codes JINTRAC. Various fuelling rates/locations were investigated and it was found that high values of beta, and acceptable levels of power load on the divertor outer-target, can be achieved without impurity seeding for separatrix densities above 2 x 1019 m-3 and in conditions of partial divertor detachment. The 0D plasma parameters of the above reduced-power advanced scenario are discussed along with comparison against the reference values of the highest beta scenario in the JT-60SA research plan
