Abstract:
The underground nuclear power plant researched in China after FUKUSHIMA nuclear accident is a more safe and more acceptable style of nuclear power plant. The containment of underground nuclear power is buried about 180 meters underground, while the pool full of cooling water is equipped on the ground. The driving head of nature circulation of passive heat removal system of secondary side is sufficient due to the height difference of steam generator and cooling pool. The functional requirement, system components, equipment character and operating of the passive heat removal system of secondary side in underground nuclear power plant are presented in this paper.
