The Plasma Fusion Reactor, typically called simply Plasma Reactor, is small nuclear power plant capable of generating large quantities of electrical energy without any release of radioactive waste.
Invented by Noriko Null by reverse-engineering the power core of a Talos robot, it was first commercialized by Leiko Tanaka who stole its design. The source of much of Noriko's income, the Plasma Reactos have rapidly replaced all other types of nuclear reactors.
A miniaturized version, small enough to be fit on a belt, is not available to the public and is used to power other technologies like the Phoenix and the Excess and Overkill suits.
