英文摘要: To guarantee the safety of nuclear reactor, the stress analysis and structural integrity evaluations of the reactor pressure vessel (RPV) are very important for Thorium-based Molten Salt Reactor (TMSR), whose design temperature and design pressure are 700 degrees C and 0.5MPa respectively. In this paper, the structural analysis is firstly carried out by using a 3D coarse model of the RPV. Secondly, the reactor core support are recalculated by a sub-model with a fine mesh and the analysis results are evaluated according to ASME NH code, including stress evaluation, strain and deformation evaluation and creep fatigue evaluation. It was found that the initial structural did not meet the requirements of creep-fatigue limits. Finally, structural optimization designs are proposed, such as T-shaped modified structure and fillet design, whose results can satisfy the requirements of creep-fatigue limits. These analysis methods and results provide some practical engineering guidance to the structural design and safety evaluation of the RPV in TMSR.
