Tony/Raven
Before we switched tracks (before I understood what could happen to weapons out of my hands), I held nearly all the government weapons contracts. If the United States shot it, it was likely Stark Industries.
Then I got kidnapped. Long story short, I can pull an element out of the core of the warhead and build a reactor with the spare parts. It won't be pretty but if you give me space and a forge, I can fashion them, then we can set them up. Since the settlements will be further from the dam, it will afford them self-sustaining energy. No plug-in required.
