A team of six Russian specialists from turbine manufacturer Power Machines have come to Kudankulam Nuclear Power Project (KNPP) to complete the vibration adjustment of the new generator stator in the second unit, a Russian state atomic corporation Rosatom official said.
India’s atomic power plant operator Nuclear Power Corporation of India Ltd (NPCIL) has two 1,000 MW power units supplied by Rosatom.
The second unit was stopped on Thursday afternoon so that the high vibration in the generator is set right.
“In March 2020, preventive maintenance was completed at Block 2 (Unit 2), in the framework of which the generator stator was successfully replaced,” the Rosatom official told IANS.
The unit was operated at a lower capacity due to the need to complete the vibration adjustment of the new stator.
“This is a common world practice for this type of electrical machines,” he added.
