The thread here is centered around vanilla IC2 reactors only. The thorium cells come from a
infamous or awesome addon named GregTech.
If it's centered around vanilla IC2 designs, how come there's been a discussion abput thorium-reactors ON THIS VERY PAGE?
EDIT: Okay, not on this very page, but the page that you posted on. And BTW pageclaim for plutonium-reactors.
