The VVER-1200 block reaches 90% of its capacity

12 August 2019

On July 29, 2019, the innovative VVER-1200 reactor power block No.2 of the Novovoronezh NPP-2 (the Novovoronezh NPP 7th power block) reached 90% of its capacity. This means that the new 3+ generation power block has entered its next phase of low-power testing during the pilot production stage.

The pilot production is the final step before the power block is launched. The low-power testing includes trials at 40, 50, 75, 90 and 100% of the capacity.

Once the nominal capacity is reached, the power block undergoes warranty, which is then followed by the power block’s commissioning.

Since its power start-up, the power block has delivered over 683.5 M kilowatt-hours of electric power, which is compatible with the annual output of a modern wind farm. Besides, this amount of electric power is enough to power 43 high-tech small nuclear power cities like Novovoronezh for three months.

The new power block will be launched operational in late 2019.
