It would have to be something other than bronze to be used in nuclear power plants. Copper alloys are verboten now, and even a lot of fossil plants are getting rid of copper alloys as the copper tends to leach out and foul steam generators and boiler tubes.
This research merely proves that they can break this ‘law’ under certain conditions. The metal used was just the beginning. If it can be done with this metal combo, then it most likely can be done with other metal combos as well...................
I guess the cupronickel tubes and tubesheets in heat exchangers would be out of the question then. Unfortunately most nuclear plants have dozens of these style of shell and tube heat exchangers in operation. Stainless steel doesn’t conduct heat nearly as well as most copper alloys.
Not to step on your toes or anything, but I built a lot of replacement parts for those heat exchangers.
