In the south of Slovakia, between the towns of Nitra and Levice, there are four WWER 440/V-213 pressurised water reactors of Mochovce NPP.
The Unit 1 have supplied electricity to the grid since the summer of 1998, the Unit 2 since late 1999. In 2008, gross power output of each unit was uprated from 440 to 470 MW by 7% increase of the reactor power, and in 2020, the Unit 2 electrical output was uprated again to 505 MWe by replacement and modification of the secondary circuit components. The same electrical output uprate of the Unit 1 is planned in the spring of 2021.
Construction of Units 3 and 4 in in the final stage and the reactors shall be put in operation in 2021 and 2023, respectively.
The Mochovce units have passed through a design evolution with a number of improvements evaluated and approved by Slovak and international experts, and meet all international nuclear safety standards.
