Russian nuclear utility Rosenergoatom has reconnected unit 1 of the Rostov NPP to the grid after it was shutdown for some seven due to an equipment malfunction. The unit was automatically disconnected “due to a false alarm of the generator protection system, Rosenergoatom said, adding that the equipment had been checked. During its temporary outage, schedules for limiting energy consumption were introduced in the south of Russia. “In the energy system of the south of Russia, due to a malfunction of the generating equipment at the Rostov NPP in conditions of increased loads on the energy system, temporary schedules limiting consumption by 1.5 GW have been introduced in order to maintain the stability of the energy system,” the Ministry of Energy reported.
During the outage units 2&4 at the plant continued normal operation. Unit 3 was closed for scheduled repair and maintenance. The Rostov NPP with four VVER-1000 reactors is the largest energy-generating facility in southern Russia with a total capacity of 4,071 MWe. It provides around 75% of the power generation in the Rostov region and is connected to the grid of other southern regions. The south of Russia has been affected by an abnormal heatwave, which has caused power outages in several regions.
