We all know that when an atom splits, it releases a lot of energy, so I think that when Plutonium releases neutrons on TPT, it should make far more pressure than it currently does. This will make nukes on TPT a lot more effective and realistic. Right now nukes on PT just seem too weak.
You should have seen it on the original PT, Simon gave it a MAJOR boost in power a long time ago. I don't really think it needs to be more powerful, try using a distilled/compressed DEUT bomb, those have a good amount of power.
When you build a DEUT bomb fill it with -273.15 DEUT, when it's ABSOLUTELY FULL heat the DEUT to 9725.15. When the bomb goes off the pressure and density of the DEUT cause tendrils of DEUT to shoot out.
