This Mod was made for Biomass modpack, but should work standalone.
It reworks nuclear to be more powerfull than bio-fuel generators, to serve as a viable lategame option to replace those.

Because Uranium is much harder to come by in the modpack, there was no incentive to use reactors ever.

Features

• Rebalances Nuclear to be more powerfull, but also more lategame
• Incorporates it into true nukes research tree
• Reactors now explode with a 20t nuke instead of vanilla explosion
• Increases Fuelcell Energy to 100GJ, Breeder cells to 20/10Gj
• Increases Reactor output to 1GW
• Decreases Neighbour bonus to .25
• High temperature Heat exchangers and Turbines to keep up
