Well back in the thread, I said I didn't think there were any rules for that.

I wasn't entirely right about that.

The external radiator design switch includes rules (not very involved or realistic, likely, but rules) for ships overheating when the radiators are retracted, and for using heat sinks to hold off that event. These could provide a starting point to build on.

While I don't see any rules about how that interacts with detection, it would be reasonable to suggest that reactors have reduced heat signature when radiators are shut down. (Rockets probably shouldn't, because of hot exhaust, but that doesn't matter if you're using reactionless.)

If you give that a -2 to signature, fission reactors are compatible with stealth. If you gave a -3 or more, all reactors would be.
I don't know any 3e, so there is no chance that I am talking about 3e rules by accident.
