Voronezh Region, February 20 - Neftegaz.RU. Fuel loading began right on schedule at the Novovoronezh Nuclear Power Plant II, unit No. 2 equipped with the VVER-1200 reactor.
The 1st batch of 163 fuel assemblies were successfully installed with the remaining assemblies to be loaded within 5 days. The initial fuel loading marks the beginning of the reactor start-up.
The reactor will then achieve 1st criticality - the moment when a chain reaction is launched in the reactor for the 1st time and the core parameters required for the reactor’s further operation are established. The next stages include connection to the grid, power ascension testing and the commencement of commercial operations.
«This operation marks the beginning of the reactor start-up, which means that all operations related to the construction of unit No. 2 at the Novovoronezh-2 have been accomplished. Further operations will prepare the unit for first criticality and electricity production. The unit is scheduled to begin commercial operation by the end of this year,» Andrey Petrov, the Rosenergoatom’s director general said.
The VVER-1200 is the flagship of Rosatom’s generation III+ PWR-type reactor and the world’s only generation III+ design in series construction. Unit No. 2 at the Novovoronezh-2 NPP is going to be the 3rd in the series following unit No. 1 at the same NPP, launched in 2016, and unit No. 1 at the Leningrad-2 NPP, launched in 2017. Unit No. 1 at the Novovoronezh-2 has generated 16,841 bln KWt/h so far.
