Nuclearelectrica is trading 4.5% up at RON 67.50 after the Romanian army launched an emergency operation to redirect Danube river flow and secure cooling water for the Cernavoda nuclear plant. - Unit 1 of the Cernavoda plant was temporarily shut down on July 28 due to record-low Danube levels, while Unit 2 was kept online after a technical assessment. - The military operation, which includes blasting rock formations and scuttling barges, aims to maintain critical water levels for the plant's cooling systems. - Investors are responding to ongoing efforts to manage the drought's impact on energy security, alongside a positive broader market sentiment.
