Two Kudankulam NPP power units connected to India’s power grid

The task for scheduled preventative maintenance preparation was set at the first meeting of the Joint Coordination Council held on October 15, 2019.

The second Kudankulam NPP power unit is stably working after undergoing scheduled preventative maintenance on March 14, 2020.

“The scheduled preventative maintenance was completed ahead of schedule, which proves the fact that NPCIL and ASE specialists not only have a common language, but also can work together as a coordinated team,” noted Igor Korolchenko, Head of Technical Support Directorate for Blocks 1 and 2. “We were working against an approved schedule, but due to good mutual understanding have completed tasks ahead of schedule. For example, works on the generator stator were completed in 75 days instead of 84.”

The task for scheduled preventative maintenance preparation was set at the first meeting of the Joint Coordination Council held on October 15, 2019. Pursuant to the decision taken by the JCC the parties have organized a series of bilateral meetings where they have worked out and approved the schedule taking into account ASE’s experience of doing similar jobs on other power units.

The scheduled preventative maintenance was started on December 15, 2019. In addition to works on the generator stator the scope of maintenance included metal stress control, components servicing, repairs and testing of main and auxiliary equipment of the power unit in accordance with the schedule.

The unit start-up after the scheduled preventive maintenance is an essential stage on the roadmap to sign the final acceptance act of power unit 2.
