TJ, I'm not sure about that nuclear inhibiter thing. I don't see anything about in memory alpha, so as far as Trek canon goes, it's a fuel type.
I am sorry IGard, I was thinking of TriLithium in the Star Trek Universe...
I think Tom Clancy mentioned it as an inhibitor in Sum of all Fears.
Shame on me, I got my universes mixed up.
