2MW TMSR-SF关键物理参数计算

2 MW Thorium-based Molten Salt Reactor with Solid Fuel (TMSR-SF) designed by Shanghai Institute of Applied Physics (SINAP) as a test reactor was designed. The neutronic investigation is conducted by developing a 3-D model for the reactor with MCNP-4C. The core model includes the pebble fuel, control rod, reflector, fluoride salt coolant, boron absorption pebble. Core physics parameters of TMSR-SF including the effective multiplication factor, the initial excess reactivity, shutdown margin, control system worth, power density distribution, and kinetics parameters are obtained, which are used as input parameters for neutronic optimization and the thermal-hydraulic analysis of the TMSR-SF.
