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

18.03.2020
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.

For reference:
Implementation of Kudankulam NPP project in Tamil Nadu state in southern India involves construction of 6 power units with VVER-1000 reactors.
The developer - the technical customer of the facility - is Nuclear Power Corporation of India.
The general designer and supplier of equipment is ASE EC JSC.
A Protocol on final takeover of power unit 1 was signed on April 5, 2017.
A Certificate on acceptance of power unit 2 was signed on January 19, 2018 upon the results of guarantee tests.
Currently, power units No. 1, 2 of Kudandulam NPP are operating at the capacity established by the operation schedule.
In January 2016, the Indian regulator granted permission for starting the construction of power units 3 and 4 of Kudankulam NPP.
On October 23, 2017 first concrete pouring was implemented at power unit 4.
On June 1, 2017 General Framework Agreement for the construction of stage three of Kudankulam NPP in Tamil Nadu state (India), as well as Intergovernmental Credit Protocol required for the project implementation, were signed.
