200MW 供热堆余热排出过程的分析

Study for Residual Heat Removal Process of200MW Heating Reactor

２００ＭＷ供热堆采用自然循环的余热排出系统，具有非能动安全的特点。程序ＴＲＡＣＰＦ１采用了带有不可凝气体场的两相二流体非平衡态的流体动力学模型，被用于余热排出系统的分析。但是，供热堆系统和压水堆核电站不完全相同，在将这部程序用于供热堆分析时，做了一些修改和补充，例如补充了流体横掠冲刷管束的传热计算式和阻力损失计算式等等。分析结果表明：自然循环的余热排出系统能够保证供热堆的停堆安全。

A residual heat removal system (RHRS) with natural circulation is used in 200 MW Heating Reactor.It is a passive safety system.Due to its two phase two fluid hydro dynamic model with an in condensable gas field,TRAC PF1 cods is used to analyzes the transient performance of this system.But there are some difference between heating reactor and PWR,some modify and supplement have to be done,such as supplementing the heat transfer and fraction loss formulations of crossing bundle et al.The analyzed result show:the shutdown is safety for the 200MW heating reaetor used RHRS with natural circulation.
