Have you gone to the kett base? They pull power from the radiation.
They possibly optional, given some things in this game trigger due your own exploration, instead of laid bare and explained all the time. The first time I played, I went to that fortress before doing anything else for Massani, so his conversation was already fixed for that situation.
Actually Massani's dialogue is bugged in that convo. On my first playthrough, I killed Invictor before speaking to Massani and his dialogue still pointed out that I hadn't taken the "crown jewel."
