WebSensitive detectors constantly monitor different aspects, like temperature, pressure and the reactor power level. When necessary, CANDU reactors can safely and automatically shut down within seconds. Shutdown systems. All nuclear power reactors in Canada have two independent, fast-acting and equally effective shutdown systems. WebUnenriched natural uranium is appropriate fuel for a heavy-water reactor, like a CANDU reactor. On rare occasions, earlier in geologic history when uranium-235 was more abundant, uranium ore was found to have naturally engaged in fission, forming natural nuclear fission reactors.
