【摘要】 以200 kW空间快堆RAPID-L为对象,建立瞬态分析模型,分析在尤保护超功率事故UTOP和无保护失流事故ULOF下的瞬态特性。计算结果表明：快速型锂膨胀模块(LEM)可随冷却剂温度变化自动快速响应,能够在不停堆情况下保证反应堆的安全,因此,RAPID-L具有固有安全特性。更多还原

【Abstract】 The transient analysis model for the 200 kW Advanced Space Fast Reactor RAPID-L was developed.The unprotected transient overpower(UTOP) and unprotect- ed loss of flow(ULOF) were analyzed by this model.It is demonstrated that the quick lithium expansion module(LEM) can response promptly according to the coolant tem- perature variation and safeguard the reactor without shut-down,so RAPID-L has the characteristics of inherent safety.更多还原
