Restricting nuclear reactor's and terraformers

[Shiny]

How can I restrict the use of nuclear reactors and terraformers? I'm not seeing them in the IC config file. Preferably I'd like to completely disable terraformers and add reactors to a PEX group.

Try NoItem.

the setting are in the file, I just turned down the blast radius of the nuke reactors to make it same as tnt
