摘　　要：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流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差分法，选用适合各种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水力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的计算表明：本程序的计算结果与相应的实验数值及其它计算程序的计算结果相比较，符合很好。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.
