| 摘 要： | 为了研究钠冷快堆的固有安全性,研究了适用于钠冷快堆系统分析的理论模型,根据钠冷快堆的特点开发了SAC程序。针对钠池温度计算不准确问题,提出了两区模型。利用三维模型计算钠池主流区,采用提出的两区模型计算钠池温度的瞬态响应。选取了美国实验增殖反应堆(EBR-II)的无保护失流事故实验进行计算对比分析,采用三维钠池模型对钠池流场进行计算和分析,采用两区模型有效地计算了钠池温度瞬态响应。程序计算的事故瞬态结果与实验结果符合较好,验证了SAC程序进行快堆瞬态计算的准确性,同时证明了利用金属燃料的钠冷快堆的固有安全性。

| Abstract: | In order to research the inherent safety of SFR, the model suitable for SFR was researched and SAC code was developed according to the characteristics of SFR. In order to solve the problem of inaccurate temperature calculation of sodium pool, a two-zone model was proposed. Three-dimensional model is used to calculate flow pattern in the sodium pool and two zone model is used to calculated sodium temperature. The Loss of Flow Without Scram accident experiment of EBR-II is selected to validate the code. The three-dimensional sodium pool model is used to calculate and analyze flow pattern in the sodium pool and two-zone model accurately simulates the main flow phenomenon. The results calculated by the code have a good agreement with experiment and the code is validated to be effective for safety analysis of SFR. The inherent safety of SFR which adopts metal fuel is validated. |
