There have been reports explaining how some reactors have been forced to reduce power output, as their cooling ponds, lakes, or coastal ocean water temperatures increase on account of climate change, exceeding the original design heat rejection capabilities of the cooling water / heat-exchangers.
Also, warming seas are amplifying jellyfish populations, which are clogging the cooling water inlets of coastal nuclear power plants.
And nuclear-powered British Royal Navy ships have been forced to leave the Persian Gulf area at times, because their onboard reactors cannot reliably reject reactor heat to the increasingly-the hotter ocean water.
