Another issue with using nuclear power, especially in the western US. I originally saw this in an article about an Arizona nuclear power plant which is behind a paywall. A Google search turns up some numbers. From a UK article.
“A large nuclear power plant may use up to 1 billion gallons of water a day and, for this reason, they are often built next to rivers, lakes or oceans to utilise the bodies of water.”
