System for Active Removal of the Residual Heat Released in Vver-1000

  • Published:
Atomic Energy Aims and scope

A variant of the combination of an NPP with a continually operating low-capacity additional steam turbine is proposed and analyzed. In the event of an accident with total blackout, the proposed setup makes it possible to supply electricity to first- and second-category consumers and circulation pumps. In addition, the residual heat released is used to maintain the require power of the additional turbine. A probabilistic safety evaluation of an NPP combined with an additional continually operating steam turbine is presented. The proposed setup makes it possible to increase considerably the reliability of the electricity supply in emergency situations associated with a blackout and reduce the probability of accidents in which the core is damaged.
