Molten Salt Reactor in the Overview and Perspective of Technological Assessment

Full text: A Molten Salt Reactor (MSR) is unique in its characteristics that offer safer operation, deliver efficient power output that can assure in the sustainable energy production without CO₂ emissions. Several concepts of this kind of reactor have been proposed by stake holder with different design and configuration and up to date they are exasperating to obtain an optimum workable solution to the fuel salt composition in the foresee of neutronic properties, operating temperature, actinide and fission products solubility, chemical control and processing, materials compatibility and handling of waste. Hence, these key issues are wide open as the potential Research and Development in the specific areas of studies. In addition to that, concern arise in the viewpoint of socioeconomic, politics, public acceptance, safety and security, proven technology, proliferation resistance and physical protection that also need to give special attention in problem solving. The worldwide collaboration through Gen IV International Forum has discussed the potential of MSR and addresses on the issues globally. Recently, Malaysia has taken an initiative aiming to participate in MSR studies due to its potential as an energy source using thorium. Therefore, this paper is focusing on the technology assessment for Thorium-breeding Molten Salt Reactor (TMSR) especially on the ability of utilizing thorium as fuel. This assessment also will help to enhance the understanding of thorium beneficiation to cater for the energy demand. (author)
