The 2nd 1,000 MW unit at the Kudankulam Nuclear Power Project (KNPP) will restart generation soon, said a senior official of the Nuclear Power Corporation of India Ltd (NPCIL) on June 27, 2017.
The unit was under outage since June 25 afternoon due to control circuit malfunction, said Power System Operation Corporation Ltd (Posco).
The unit most probably would restart generation on June 28, a senior official told.
In May only, the unit was shut down due to water and steam leakage. It was reconnected to the grid several days later.
The 1st unit was shut down on April 13, for annual maintenance and refuelling, a process that would take around 2 months.
Every year, one third of the reactor's 163 fuel assemblies, or 54 assemblies, would be replaced.
This was the 2nd refuelling cycle for Unit 1.
