Why would you not build new reactors at sites that account for the changed climate, maybe with adjacent cooling lakes? Yes, Uranium is imported but fuel costs

Why would you not build new reactors at sites that account for the changed climate, maybe with adjacent cooling lakes? Yes, Uranium is imported but fuel costs and volume is a pretty irrelevant factor with nuclear energy. You can buy it somewhere else in strategic quantities and store it at home. But sure, there can be short term difficulties.
