【摘要】 本文针对压水堆发生主管道“双端断裂”的大破口失水事故而提出了一种安全装置,对其工作原理及工程上实现的可能作了浅析,对其原理性实验过程及结果作了介绍。实验表明:这种安全装置结构简单,原理正确,工程上易实现,造价低廉。它在大破口失水事故发生初期(约数十毫秒)就能充分发挥其作用。对于防止堆芯熔化具有重要意义。更多还原

【Abstract】 To guard against the PWR LOCA,a safety device is proposed in this article.The principle of the device and its application in engineering are analysed.And the principle experiments on the device and the results are also introduced.The experiments show that this safety device’s structure is very simple, its principle realizable and it is also very economic.The safety device can work effectively to protect the PWR’s core from melting in the early stage of the PWR LOCA.更多还原
