5MW低功率堆固有安全性研究

Inherent Safety Research of 5MW Low Power Reactor

理论计算和堆上试验表明,5MW 低功率堆(LPR)具有较好的固有安全性。在失去外电源事故停堆工况下,靠本身自然循环和大水池的储热能力,不依靠任何其它安全设施就可导出堆芯余热,保证反应堆的安全。

It is proved by theory analysis and some tests relative to in-herent safety that the 5MW LPR has favourable inherent safety.When Loss-of-pump power accident take place and the reactorscramed simultaneously,the reactor can be ensured,and thedecay heat is removed out of the reactor core only by naturalcirculation.
