SN Nuclearelectrica SA announces 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. This situation poses no risk to nuclear safety.

Furthermore, following on from its most recent update, SNN states that a rise of approximately 10 cm in the water level measured in the pump intake basin at Cernavodă Nuclear Power Plant has recently been achieved, as a result of the rise in the level of the Danube. This is a localised rise, which is not, as yet, accompanied by a general rise across the entire Danube River basin upstream of Cernavodă. This development is positive and reflects a current improvement in hydrological conditions compared with previous days.

At present, although the conditions are favourable, current forecasts do not indicate that all the criteria required to make the decision to reconnect at least one of the units will be met.

The water level in the power station’s intake basin remains below the threshold considered necessary for the reconnection of one or both units. The level required for the safe reconnection of the units must be maintained over a period of several days and must show an upward trend.

“Once we reach the level required for the safe reconnection and operation of the Cernavodă Nuclear Power Station, we will request, as a matter of priority, that the plant be connected to the National Energy System. 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. Nuclear safety and the safety of the plant are Nuclearelectrica’s absolute priorities.” – Mihai Gioară, CEO of Nuclearelectrica

SNN is closely monitoring all hydrological data and is collaborating with the relevant authorities. SNN is prepared to reconnect the Cernavodă Nuclear Power Plant, as soon as the forecasts become favourable and the necessary conditions are met, thereby supporting the National Energy System.

SNN will communicate any changes in the status of the Cernavodă Nuclear Power Plant, in accordance with the legal requirements applicable to a listed company.
