Unit 2 of Cernavoda NPP automatically disconnected from the grid on the evening of May 4 due to a malfunction in an insulator associated with the power output transformer, which required replacing the Cernavoda NPP Unit 2 transformer with a spare unit.
„Work to replace the electrical transformer is a complex operation that involves isolating, dismantling, and relocating the original transformer, as well as complex testing and calibration of the new transformer, in strict compliance with nuclear industry standards. During the repair work and replacement of the transformer with the spare unit, the Unit 2 reactor was kept safely shut down, with no impact on nuclear safety, personnel, the public, or the environment, in strict compliance with applicable procedures,” reads the company’s statement.
Normally, Cernavoda secures 20% of Romania’s energy.
