You dolt there was never a problem with cooling the plants. The issue was that there is red tape that limits how much water the plant can discharge into the Rhine. That could have easily been addressed if the plants were just allowed to cycle more water. The higher the flow rate the colder the water will come out the other end . The water is put through a heat exchanger and then cycled back to the river. If more water can be piped through then the reactor can maintain lower temperatures.
