摘要:10MW高温气冷堆的乏燃料贮存在具有屏蔽功能的乏燃料贮罐内,乏燃料贮罐置于乏燃料贮存库内的水泥屏蔽套内,贮罐采用干式贮存方式,通过通风冷却排出乏燃料的余热,本文通过详细的分析,并采用有限元分析程序ANSYS对温度场进行数值计算,验证乏燃料贮罐余热排出的安全性,以保证乏燃料及贮罐的最高温度低于安全限值。本文通过计算表明,忙露内球床中心溢度最高,沿径向逐新衰减,贮罐罐体内的温度分布比较均勾,温差不大,混凝土屏蔽套内的温度沿径向向外逐渐减小,内外壁温差较大。计算表明采用自然通风的方式排出乏燃料的余热从技术上和安全性上均是可行的,在自然通风工况下,乏燃料元件和贮罐的最高温度均满足安全要求,这为高温堆乏燃料元件余热排出方式的选挥择提供了理论依据。

Abstract: The spent fuel of 1oMWHigh Temperature Gas Cooled Reactor (HTR-10) could be stored in the shielded tank, and the tank is stored in the concrete shielded canister in spent fuel storage room, the residual heat of the spent fuel could be removed by the air. The ability of residual heat removal is analyzed in the paper, and the temperature field is numerically calculated through FEA program ANSYS, the analysis
