The comment you replying to was trying to not so subtly point out this is a business plot and little else. Nobody is going to pay a subscription fee to have a tree in front of their business, but they might cough up money for a third party to maintain a tank of algae out front if it was sold right

Or free if you do it in the military like I did

Not how reactors work, they are very much closed systems specifically to avoid this problem.

Think of it like and air conditioner or refrigerator. The the attempt that cool the inside by dumping heat outside uses a closed loop and the two mediums do not directly interact or mix, which is why your home isn’t full of pollen when running an air conditioner all day if your windows and doors all properly seal.

The steam you see coming off a cooling tower is not the water than went through the reactor or turbine, a secondary cooling loop is used specifically cause the plants are not allowed to release radioactive material in any form, including the cooling processes.

The real reason this idea would not work is the same problem desalination has, making clean and safe drinking water is the easy part, it’s what are you doing with all the contaminants and water products left behind that quickly becoming a concentrated pool of filth and toxins at the bottom of your heat exchanger.
