考虑核电厂独立非能动应急反应堆设施冷却系统新方案。核电站考虑采用水慢化能源反应堆WWER（NPP with WWER）。应急系统采用低温热管换热器，在整机长期停电情况下排出衰变热。提出了基于两相热虹吸管或热管的“热”反应堆设施独立紧急冷却系统方案。考虑了WWER核电厂独立非能动应急堆冷却系统低温热管换热器在整机长期停电条件下的新回路。给出了应急反应堆冷却系统和应急抢修冷却系统的电路。
The new schemes of NPP independent passive emergency reactor facility cooldown systems are considered. Nuclear power plant is considered with water-moderated energy reactor WWER (NPP with WWER). There are low-temperature heat pipes heat exchangers for decay heat rejection under conditions of complete unit long-term loss of station power as used in the emergency system. Schemes of independent systems of emergency cooldown of “hot” reactor facility based on two-phase thermosiphons or heat pipes are presented. The new circuits of WWER NPP independent passive emergency reactor cooldown systems with low-temperature heat pipes heat exchangers under conditions of complete unit long-term de-energization are considered. The circuits of emergency reactor cooldown systems and emergency repair cooldown are presented.
