Each of the two units has an installed capacity of 700 MW. Both have been shut down since August due to low Danube flows.
Unit 1 was restarted three days ago but shut down again shortly afterwards due to technical problems at the conventional block. Attempts to resume operations at Unit 2 failed on the same day because of low Danube levels.
“Regarding Unit 1, the Cernavodă NPP specialist teams are currently carrying out specific assessments and implementing plans to remedy the situation, in order to reconnect to the SEN as soon as possible. At this time, the intervention and fault remediation period is estimated at 2–4 days, followed by specific procedures for synchronisation and restart,” Nuclearelectrica said on November 10, as reported by Economedia.ro.
The Cernavodă NPP has two CANDU nuclear reactors with a capacity of 700 MW each. Both are currently shut down. Danube flows were so low this summer that there was insufficient water available for cooling.
The shutdown of the nuclear power plant has had significant effects on the energy market, as it removed the country’s largest source of dispatchable electricity generation from the grid. Romania became more dependent on imports during evening hours, contributing to higher spot-market prices, which have increasingly been reflected in consumer bills.
