Concreting of the foundation slab was finished at Unit 1 of Kursk II nuclear power plant.
Over 16,000 cubic meters of self-compacting concrete were poured into the foundation. The use of self-compacting concrete helped perform the task faster and with higher quality. After the concreting was completed, work began to build containment walls and internal containment structures.
“Kursk-II is based on the advanced VVER-TOI design. This plant will be a reference for all subsequent nuclear plant construction projects in Russia and other countries,” said Alexei Deriy, ASE Vice President for Russian Projects.
Kursk II with its two 1,255 MW reactor units is designed to replace the existing Kursk Nuclear Power Plant. The new plant is based on the VVER-TOI design concept involving VVER-1200 reactor solutions and providing for increased capacity and improved safety. VVER-TOI units will be able to withstand a 9 magnitude earthquake and direct crash of a 20-ton fighter jet. The crash of a 400-ton airplane (like Boeing-747) is also taken into account. Reactor units will remain absolutely safe in severe accidents, such as a loss-of-coolant accident (LOCA) or total power outage. If the both of these accidents occur simultaneously, power units will be able to operate standalone for up to 72 hours.
The VVER-TOI design provides for the development of a data model for power units. Information accumulated in the engineering data management system will be used at different stages of the plant’s life cycle, from developing a design concept to decommissioning.
