    There are a number of 6-8GWe nuclear plants that dump 15+GW into the nearby sea (or in the case of Bruce, Lake Huron). I don’t see it being much of an issue. Better than virtually any other cooling option.

    The issues are maintenance, energy source, and equipment supply.

      The plants on the lakes so monitor the water temp so they don’t affect the ecosystem during the warmer seasons still.

      But I doubt the one in NB had to worry about that when more water flows by it than all the rivers in the world combined.

      But yes, much better source of cooling at the cost of maintenance and equipment. Just like tidal power but with fewer moving parts.

        Yeah, but look at the magnitudes of the heat units involved. Modern nuclear plants generate 0.6-4.5 GW at around 30% thermal efficiency (so they generate between 2-15GW of heat). These underwater data centers are looking at 25 MW (0.025 GW) while surrounded by water in 5 of the 6 3-dimensional directions.

        There is some risk to local ecosystems, but we’re literally talking 2 or more orders of magnitude difference compared to nuclear plants or other thermal plants.

          Oh 100% And I was thinking of extreme examples with the Pickering Nuclear station having (once up to) 8 550MW reactors dumping heat into a fairly shallow part of the lake and the NB reactor having no chance to remotely affect the bay of Fundy temps lol.

          Lil halicination farms on the seafloor are a dumb idea but not because of heat affecting the environment beyond the thousands of organisms that would live directly on them.
