WebYou do not state which reactor you are using, but this page says ReactorBase is the base class for Reactors. Also on the same page, it mentions an instance variable running that is further explained here. It says. running = A bool which is True from during startup to during shutdown and False the rest of the time. WebThe reactor core, and all associated support and ali gnment devices, are housed within the reactor vessel (cutaway view on page 4-10). The major components are the reactor vessel, the core barrel, the reactor core, and the upper internals package.
