Hungary’s Paks nuclear power station has reduced electricity generation to one unit operating at 50% capacity and faces a full halt in production if water levels in the Danube River fall further, operator MVM said.

MVM said the shutdown of the still operating turbine generator at Unit 4 was due to begin at 01:30 local time on 2 August, leaving only Unit 2 in operation at half capacity. The company said this production level can be maintained only as long as the water level allows safe operation of the pump impellers used to cool the unit.
