On NVNPP-2 started installation of the thrust ring of the reactor vessel

In the reactor building unit number 1 Novovoronezh NPP-2 (general designer and general contractor — JSC "AEP", Moscow) started assembling the thrust ring of the reactor vessel, which is using the polar crane mounted on a regular place in the reactor cavity at the level of + 16.5 meters.

Thrust ring (weight — more than 18 tons, height — 0.6 meters in diameter — about 5 meters) is part of the equipment of the reactor shaft and is designed to hold the body of the reactor on the displacements of the thermal expansion.

Installation of the equipment — one of the most important steps that precede welding of the main circulation pipeline, which connects the primary circuit equipment (reactor vessel, steam generators, reactor coolant pumps). Commissioning of the first unit of Novovoronezh NPP-2 is scheduled for 2014.
