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.
Upcoming in Russia, the launch of the new power unit No. 2 of Leningrad NPP-2 will be a landmark for several reasons, the chief editor of the information portal on nuclear energy AtomInfo.ru Alexander Uvarov.
AES-2006 is designed in the XXI century the nuclear power plant project so-called generation 3 with improved technical and economic indicators. The units of this project have now become the main export product of the state Corporation "Rosatom" - they already planned to build in different countries.
Regardie took custody of the power unit No. 2 of Leningrad NPP-2 in anticipation of the beginning of loading of nuclear fuel in its reactor, the Agency said the information and public relations of the LNPP.
Start loading nuclear fuel into the reactor is scheduled for mid-July, the report says. This will be the start of the so-called stage of physical start-up of the unit. Then followed the beginning of a controlled self-sustaining nuclear chain reaction in the reactor - the actual physical start, then energy start - start the issuance of a unit of electricity in the network, trial operation and complex testing of the unit. Commissioning of power unit No. 2 of Leningrad NPP-2 into commercial operation is scheduled for 2021.
Concern Rosenergoatom (the operator of all nuclear power plants in Russia, included in the state Corporation "Rosatom") denied reports by several foreign media, including the Ukrainian, about the incident at unit 2 of the Leningrad nuclear power plant.
According to these publications, supposedly last Saturday in the turbine building of the second unit of LNPP radioactive steam.
No deviations from safe operation conditions in nuclear power plants in Northwest Russia in June was not a radiation environment consistent with normal values reported RIA Novosti, the official representative of the concern "Rosenergoatom" (the operator of all nuclear power plants in the Russian Federation, member of the state Corporation "Rosatom").
Earlier on Friday, some media reported that in early June, the authorities of nuclear and radiation safety in Sweden, Norway and Finland recorded in the atmosphere over the territory of Northern Europe a slight increase in the concentrations of radioactive isotopes with so-called reactor origin. It was also reported that, according to calculations by the National institutes of health and the environment (RIVM) of the Netherlands, these isotopes allegedly received from Russia, and that the cause of the incident may be the depressurization of the fuel element in a reactor of any nuclear power plant.
Russian NPP started the gradual lifting of restrictions which were introduced in April this year on the background of the situation with coronavirus infection, said Tuesday the Department of communication of JSC "concern Rosenergoatom" (which is included in the electric power division of Rosatom).
The corresponding order was signed on 23 June 2020, the General Director of "Rosenergoatom" Andrei Petrov.
