一体化压水堆蒸汽发生器的热工水力瞬态特性分析

一体化压水堆的设计是将蒸汽发生器及稳压器等一回路所有部件都放入压力容器内，以提高安全性，采用可以精确模拟直汉蒸汽发生器二次侧水的饱和点，蒸干点位置等重要参数随时间变化的可移动边界并分法，选用适合各中换热工况的一整套换热关系式，建立了可以模拟一体化压水堆直流蒸汽发生器的稳态及瞬态热工不特性的物理及数学模型，并编制了计算程序，经对Ｂａｂｃｏｃｋ和Ｗｉｌｃｏｘ公司１９管直流蒸汽发生器实验装置进行了计算有

Thermal Hydraulic Transient Behavior Calculation of Once through Steam Generator of Intergrated PWR

Once of the design aspects to improve reactor safety is the integration of the steam generators(SG) and all the reactor components including pressurizer into the vessel.Utilizing a movable boundary spatial discretization technique and choosing suitable heat transfer correlation,the physical mathematical model and calculating code to predicate the thermal hydraulic behavious of once through SG are established.Through calculation to once through 19 tube SG experiment of Babcock and Wlcox company,the calculational results shows that this calculational results are in agreement with the experimental data and other computational prediction.
