高温气冷堆球形乏燃料处置策略及容量探讨

Discussion on the Disposal Strategy and the Capacity Analysis for the Spherical Spent Fuel of High Temperature Gas-cooled Reactor

核电作为清洁高效能源形式,在使用时也带来了高放射性乏燃料妥善处置问题,而目前全世界只有不到1/3的乏燃料进行了后处理,与传统轻水堆乏燃料处理处置研究相比,高温气冷堆乏燃料相关研究更加匮乏。本文梳理了高温气冷堆乏燃料处置的情况,分析了直接整体处置、分离石墨处置及后处理燃料核芯处置三种处置策略,计算了高温气冷堆示范工程平衡堆芯后年产生乏燃料的容量,并进行了分析及优缺点比较。

Nuclear energy is a clean and efficient energy,but also brings about the problem of proper disposal of spent fuel when in use.At present,less than 1/3 of the spent fuel has been reprocessed in the world.Compared with the study on spent fuel treatment and disposal of light water reactors,that of high-temperature gas-cooled reactors is even more scarce.This paper sorts out the situation of spent fuel treatment and disposal of high-temperature gas-cooled reactor,and analyzes the corresponding the direct overall disposal,separated graphite disposal and reprocessing core disposal strategies,and then calculates the capacity of spent fuel produced in the year after the core balance of the high-temperature gas-cooled reactor demonstration project in detail,finally carries out the analysis and comparison of advantages and disadvantages of different strategies.
