Unit 1 of the Kudankulam NPP was successfully connected to the power grid after a scheduled preventive maintenance (SPM). Rusatom Service JSC, despite the restrictive measures associated with the spread of coronavirus infection COVID-19, provided the customer with a full range of services for the timely implementation of complex technological operations. In particular, for the first time in 24/7 mode, remote technical support was provided to an Indian customer during refueling. This became possible thanks to the professionalism and well-coordinated work of Russian and Indian specialists.
