Stock neighbor bonus just gives nuclear reactors energy out of thin air - fix that! Now the radiation from neighboring units speeds up the decay of fuel instead. Not that it is a problem, given how plentiful uranium really is, just build more! That's a plus in my book. You never really have much incentive to scale enrichment in the base game, so maybe now?

You don't have to change your blueprints, reactors will still produce the same power, just consume cells faster. Just make sure to check the "safe deletion" option if you want to disable the mod later in game. Known issues: Reactors get bonus even when their neighbors are off. I think that's acceptable if you don't deliberately exploit it.
