Park a nuke plant next to the ocean waste heat from cooling the reactors distills pure water.
Yes this is the way...

A nuke puts out 2 units of heat into it’s cooling heat sink for every one unit of electricity. Using waste heat you can make a medium sized river worth of fresh water with rapid spray desal, or low temp vacuum desal or go triple win and do adsorption cooling to sea ice, melt that now fresh water ice with loops of propylene glycol to melt it at 32F and take all that cold glycol and send it to a district cooling system. You get cheap electricity, loads of fresh melt water, and tons of cooling which is 75% of your electric load in hot climates so you just multiplied the number of buildings that nuke can power by not running HVAC units and district cooling them instead. It’s win win win. Ask GE Hitachi for the ESBWR in 1600 MW form. They built the more complex older brother the ABWR in 39 months from first concrete to first fueling twice in Japan. The ESBWR has 50% LESS concrete and no active cooling systems it’s all passive cooling and natural convention driven no pumps in the reactor vessel, no large pipes and it cannot melt down it’s under the gravity driven flood tanks that open as soon as it scrams and vents to the suppression pool. You only need to add water to the top pool after 7 days and you can do that with a probable hand carried 3 inch gas driven pump. That’s assuming your triple redundant feed water systems, double redundant fire suppression systems, and on site gravity driven water tower pressure system are all compromised. There is hose hook ups for fire truck water and you could use a hand carried pump to fire hose water from your cooling tower basins or cooling pond directly to the triple diverse external hose points that lead to the top gravity pool, from there it flows down to the core, fuel storage pool, and containment cooling condensers all by physics humans don’t even need to be there just get the water to the top pools one of three and physics does the rest. It’s the safest reactor humans have ever designed by core damage frequency. I would gladly live inside the plant gates sleeping the sleep of babes knowing my air is clean , my water is pure and my house is 65F all while the wonderful machine hums away a few hundreds of feet from my bedroom.
