Key facts
- Reconnection requires the intake level held over several days with an upward trend
- Rise is localized; no general rise yet across the Danube upstream of Cernavodă
- CEO Mihai Gioară says grid connection will be requested as a priority once the level is reached
- No risk to nuclear safety from the shutdown, Nuclearelectrica says; monitoring hydrological data with authorities
Nuclearelectrica said on October 29 that Units 1 and 2 of the Cernavodă nuclear power plant are being kept in a safe shutdown state, in accordance with nuclear safety regulations and standards, and that the situation poses no risk to nuclear safety.
The water level in the plant's pump intake basin has risen by approximately 10 cm as the level of the Danube has risen. Nuclearelectrica described the increase as localised and said it is not yet accompanied by a general rise across the entire Danube River basin upstream of Cernavodă.
The level in the intake basin remains below the threshold considered necessary to reconnect one or both units. The required level must be maintained over several days and show an upward trend. Nuclearelectrica said current forecasts do not indicate that all the criteria for a reconnection decision will be met.
CEO Mihai Gioară said the company will request, as a matter of priority, that the plant be connected to the National Energy System once the required level is reached. "At present, against the backdrop of a volatile, as yet unsustainable rise in the water level in the intake basin, we are acting strictly in accordance with the applicable operating procedures of the Cernavodă Nuclear Power Plant," he said.
Nuclearelectrica said it is monitoring hydrological data and working with the relevant authorities, and will communicate any change in the plant's status as required of a listed company.
