The Unit 3 and Unit 4 reactors at the Dukovany nuclear power plant in the Czech Republic have been shutdown after a leak was discovered on Monday in the cooling water system which cools technical and safety equipment at the plant.
The leak was found near where ongoing construction of new cooling towers was taking place, but no information was released inferring the construction activities had caused the leak. Utility workers are examining what role the construction activities may have played in the leak.
The reactor cooling system has been reconfigured to use a secondary cooling system. The reactor could operate for a few days using the alternative configuration, but the repair would take longer to complete, leading the utility to commence with an unplanned shutdown.
The Dukovany nuclear power plant was constructed by Czechoslovakia and Russia in the mid-1980s.
