钠冷快堆中池式钠火的计算分析

文章论述了根据池式钠火的特点建立了理论模型 ,编制了SPOOL程序。该程序模拟钠燃烧过程中钠和氧气的化学反应 ,钠燃烧热在各种介质中不同方式的传递 ,钠气溶胶的产生、沉积 ,以及在各种通风条件下多种介质的质量和能量交换等瞬态过程 ,描述了钠燃烧过程中各种特征参数随时间的变化。其主要的计算参数包括房间内气体的压力和温度、房间建筑结构的温度、钠气溶胶质量浓度等等。用俄罗斯别洛雅尔斯克核电站实验和法国卡桑德拉 3号实验的数据 ,对SPOOL程序进行验证的结果表明 ,该程序的计算结果可信。该程序为国内钠冷快堆中池式钠火事故的安全分析提供了分析方法

Sodium Pool Fire Analysis of Sodium-cooled Fast Reactor by Calculation

Theoratical models were established according to the characteristic of sodium pool fire,and the SPOOL code was created independently.Some transient processes in sodium pool fire were modeled,including chemical reaction of sodium and oxygen;sodium combustion heat transter modes in several kinds of media;production,deposition and discharge of sodium aerosol;mass and energy exchange between different media in different ventilating conditions.The important characteristic parameters were calculated,such as pressure and temperature of gas,temperature of building materials,mass concentration of sodium aerosol,and so on.The SPOOL code,which provided available safety analysis tool for sodium pool fire accidents in sodium cooled fast reactor,was well demonstrated with experimental data.
