At Leningrad NPP-2 began loading fuel into the reactor of the new unit
The staff of the Leningrad NPP-2 began loading nuclear fuel into the reactor of the new power unit. This was reported by the press service of the concern "Rosenergoatom".
So the unit began the so-called stage of the physical start-up. Only the VVER-1200 reactor will load the 163 fuel assemblies with nuclear fuel. The researchers then launch it self-sustaining controlled nuclear chain reaction — the start, and then hold the power start-up — the issuance of a unit of electricity in the network, trial operation and complex testing of the unit at rated power. All this planning to perform in the course of this year.
The first stage of the cycle takes about two months, the concern noted.
The new power plant scheduled to enter commercial operation in 2021.
"Fitpack is only the first step, we have a long, long way: this fall we will connect the unit to the network and develop the first kilowatt-hours of electricity, gradually mastering the levels of reactor power to 100%. We will perform hundreds of tests to verify the reliable and secure operation of all technology systems and security unit to have in early 2021 to introduce a new unit in commercial operation", — noted the Director of Leningrad NPP Vladimir Pereguda.
With the launch of this unit in Russia will complete the construction of the first series of nuclear power units with reactors VVER-1200 in the modern Russian project NPP-2006, developed in the twenty-first century. Nuclear power plant of this project have now become the main export product of Rosatom.
Leningrad nuclear power plant — branch of JSC Concern Rosenergoatom (part of Rosatom). The station is located in the town of Sosnovy Bor, 40 kilometers West of St. Petersburg on the Gulf of Finland.
SELA is the largest in Russia with total installed electrical power (4200 MW) and the only two types of reactors: in operation there are three operating unit RBMK-1000 (uranium-graphite nuclear reactors of channel type on thermal neutrons electrical capacity of 1000 MW) and one unit of the current generation 3 VVER-1200 (water-water energetic reactor with capacity of 1200 MW) are also classified as unit No. 1 of Leningrad NPP-2.
Leningrad nuclear power plant produces the most electricity in the North-West of Russia. Its share in total generation is 30%. Thanks to the work of the four power units of LAES in Saint-Petersburg and Leningrad region burning every second light bulb.
