SGTR事故并发碘尖峰研究

Study on Accident-initiated Iodine Spiking during an SGTR

结合实际电厂运行经验数据,提出了一种新的蒸汽发生器传热管破裂事故并发碘尖峰分析方法,并对新方法的合理性和保守性进行了分析。最后,将现有方法和新方法运用到实际电厂进行案例分析,结果表明,新方法得到的剂量结果可以满足我国国标的剂量验收准则。

This paper introduces the current methods for iodine spiking analysis then presents a new method based on the data collected from PWR plants feasibility and conservativeness. At last, through case study and comparison, it SGTR accident doses based on the new method can satisfy the Chinese limits. during an SGTR, and with discussions on its is demonstrated that the
