Control room after Leningrad 5 was connected to the gridThe new reactor is "equipped with Rosatom’s flagship Generation III+ VVER-1200 reactor" technology, Rosatom said. It was connected to the grid and reached the power capacity of 240 MW.

Before its connection to the grid, Unit 6 underwent a power start-up, which entailed a large number of tests designed to assess the readiness of the main equipment and systems to produce both thermal and electric power, as well as a step-by-step increase in thermal capacity from 1 percent to 35 percent. Reaching 35 percent of thermal capacity, the turbine generator was connected to the grid and started generating and transmitting electricity to the country’s unified power system.

Following the trial operation, Unit 6 will be shut down for an additional equipment inspection by a state commission before being put into commercial operation scheduled for 2021.

“There are two important milestones in the power unit setup process. One is the first bringing the reactor to a critical state at the minimum-controlled power level when it “awakens”. The second, which is even more important is the first connection to the grid, when the power unit begins to perform its function and produce electricity., said Rosatom First Deputy Director-General for Operations Management Alexander Lokshin.. "The country received another 1200 MW unit and strengthened its credibility as a leading power in the field of nuclear energy," he said.
