The disconnect occurred due to the activation of a protection control system at the electric generator. The reactor was disconnected from the grid on March 9, 2013, around 8:45 am, due to signals received from its excitation system.
The reconnect activities took place respecting the plant procedures, as well as the rules of protection and security, with no adverse impact on population, personnel, installations and environment, reads the release.
