We ended up next to Wylfa nuclear power station on Anglesey, the island off North Wales. We had been looking at the data on nuclear power stations in class. Wylfa is given as having half the power of the other power stations. I have found out that it is because one of the two reactors has been shut down already and the other will shut next year. It is the oldest nuclear power station still operating in the UK. There are no cooling towers. The reason is that it is beside the sea, so the water needed to run the turbine system can be taken from the sea. It is thought that the sea is such a vast pool of cold water that the thermal energy in the water that is put back will give such a small share to each individual water molecule that you won't notice a rise in the temperature. This is not the case with rivers, so a nuclear power station inland by a river would have to have cooling towers.
