Simulations of future Thailand tokamak plasmas are carried out using a CRONOS integrated predictive modelling code. The design of the reactor is based on nominal parameters of HT-6M tokamak. The code consists of a 1D transport solver with general 2D magnetic equilibria, and includes several heat, particle and impurities transport models as well as heat, particle and momentum sources. In this work, a combination of a mixed Bohm/gyro-Bohm anomalous transport model and an NCLASS neoclassical transport model are used to calculate plasma core diffusivities. The boundary condition of the simulations is taken to be at the top of the pedestal which is calculated based on an international multi-tokamak scaling. Sensitivity analyses on plasma performance of the future Thailand tokamak are investigated by varying plasma current, toroidal magnetic field and external heating schemes. It is found that the performance in H-mode plasmas such as transport barrier at plasma edge and central temperatures are found to be sensitive to heating schemes and their magnitudes. Additionally, ICRH and LH methods appear to be the most effective scheme of heating for ion and electron temperatures, respectively. Central ion temperature in the range of 120 - 750 eV and central electron temperature in the range of 1,100 - 2,750 eV with heating are expected.
