钠冷快堆中喷雾钠火的计算分析

根据钠冷快堆中喷雾钠火的特点建立了理论模型，编制了SSPRAY程序。该程序模拟钠喷雾燃料过程中钠滴的运动、钠和氧气的燃烧反应、热量传递和质量传递等瞬态过程。用该程序计算了气体和墙壁温度、气体压力、氧气摩尔份额、喷雾流燃烧速率和热量热递速率等主要参数。利用AI实验数据和美国SPRAY－3A的计算结果对程序进行了验证，结果符合较好。

Sodium Spray Fire Analysis of Sodium-Cooled Fast Reactor

The theoretical model of sodium spray fire was established according to the character-istic of sodium-cooled fast reactor,and the code SSPRAY,which modeled the transient processes in sodium spray fire such as the motion of sodium droplet,combustion reaction between sodium and oxy-gen,transfer of mass and heat,was created independently.Some important parameters were calculated in the code,including the temperature of gas and wall,gas pressure,oxygen molecule fraction,com-bustion rate of sodium spray.The code SSPRAY was validated well with experimental data of Atomics International and some calculation results of the code SPRAY-3A.
