Research On The Location Of Low-carbon New Energy Demonstration Base On Thorium Molten Salt Reactor Nuclear Energy System

The Low-carbon New Energy Demonstration Base on Thorium Molten Salt Reactor Nuclear Energy System base consists of a bismuth-based molten salt reactor system,a nuclear-based high-temperature and high-efficiency hydrogen production system,and an ultra-high-temperature molten salt energy storage and heat storage system.The bismuth-based molten salt reactor adopts anhydrous cooling,which can provide electricity for drought-deficient areas;high output temperature can realize carbon-free high-efficiency hydrogen production,centralized heating,etc.,and can also realize greenhouse gas emission reduction by utilizing carbon dioxide resources..The ultra-high temperature molten salt energy storage and heat storage system can be combined with abundant solar energy and wind energy resources in the western region to form a multi-energy complementary system,which greatly improves the efficiency of new energy technology.Therefore,how to determine the optimal site of the demonstration base based on the relevant factors of the candidate site becomes the primary problem for the construction and promotion of the low-carbon new energy demonstration base of the sulphide-based molten salt reactor.In order to optimize the site selection of the low-carbon new energy demonstration base of the sulphide-based molten salt reactor,this paper analyzes the technical requirements of the location of domestic nuclear power plants and the characteristics of the sulphur-based molten salt reactor low-carbon new energy demonstration base.Factors affecting the location of the carbon new energy demonstration base.Based on the characteristics of each specific index,the analytic hierarchy process is used to establish the set of influencing factors,and the judgment matrix is constructed by expert scoring to determine the relative importance degree between the indicators.According to the determined index weights,the sub-criteria layer membership degree matrix is constructed by expert scoring method,and the candidate comprehensive site is evaluated by fuzzy comprehensive evaluation method,and the final evaluation value is calculated.The establishment of the site evaluation index system for the low-carbon new energy demonstration base of the sulphide-based molten salt reactor makes it possible to systematically and standardize the site selection of the demonstration base,and to optimize the site selection of the same type of demonstration base and the promotion of industrialization projects.It has certain guiding significance,making the location of the low-carbon new energy demonstration base of the bismuth-based molten salt reactor more scientific and more universally applicable.Finally,using the location example of the demonstration base,using the evaluation method selected in this paper,the relevant indicators of the candidate sites in the example are comprehensively evaluated,and the optimal site in the candidate site is determined through the visual and visual evaluation.The candidate site is verified with the actual situation.In the theoretical and practical operation,the project decision makers are provided with certain site selection basis.
