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.
