And if it is just cooling, why aren't datacenters built on the coast pumping sea water for cooling?

High cost of the land on the coasts?

[cm2187]

And I guess you wouldn't even need to use sea water as a primary cooler, just as a secondary cooler. I.e. the primary cooler flows through your datacenter and the secondary cooler cools that primary cooler. So fewer pipes are exposed to sea salt.

So, same procedure as power plants.

Yeah. Instead of trying to protect the environment from what's inside (radioactivity), you are trying to protect what's inside from the environment (sea salt)!
