Abstract
A thermal model for the LS-VHTR (Liquid-Salt-Cooled High Temperature Reactor) has been developed using the RELAP5 code. The reactor operates at 2400 MW(t) and it is cooled by liquid Li2BeF4 (Flibe) salt. Two initial thermal analysis of the LS-VHTR was performed in a previous work where the simulation of only one unit cell was considered. In the present work, the RELAP5 model was increased to represent the complete core with all hexagonal blocks with two sensitivity analysis. Also the salt recirculation has been simulated. The LS-VHTR core inlet and outlet coolant temperatures, heat structures temperature and pressure drop have been simulated. The results have been compared with the available data and demonstrate that the developed model is capable to reproducing the thermal behavior of the reactor in steady state operation
