It connects all the primary loop components, including the reactor, steam generators and main circulation pumps that force the coolant (water) to flow through the circuit and transfer heat away from the reactor core. Earlier a new record was set by construction workers at the second unit of Novovoronezh II with a similar VVER-1200 reactor as they completed welding on the main circulation circuit in just 72 days. “This is a reference time for EnergoSpetsMontazh that is to weld the main circulation circuit of the Belarus NPP,” a report says. It is explicitly mentioned though that installation of the circuit will fully comply with all quality and safety requirements. The Belarus NPP is constructed near Ostrovets (Astravets), a small town in the Grodno Region of Belarus. The plant will have two VVER-1200 reactor units with a total capacity of 2,400 MWe. Unit 1 is scheduled for commissioning in 2019, to be followed by Unit 2 in 2020.
