A nuclear plant located alongside Megakat Bay. Dr. Viper planned to make its reactor go critical by having his giant scarab and grub worms breach it by tunnelling into the reactor core. However, the SWAT Kats flooded the facility by opening a valve in one of the cooling towers that led directly to Megakat Bay. This managed to cool down the breached reactor and drown the giant insects in the process, saving the city, although the plant suffered major structural damage.
The thermonuclear plant only appears in the outline for the unfinished season two finale The Doctors of Doom. It’s possible Glenn Leopold was referring to the regular Megakat Nuclear Plant, especially given the facility’s proximity to the bay, however this is unknown at this time.
