OSTI ID:6495177
Disclosed is a core reactor and method of operating same, according to which fuel elements, preferably of ball shape, are provided with an envelope of graphite and are passed in downward direction through reflector means of graphite which is simultaneously passed through by a heat transfer means and includes a ceiling reflector, a side reflector and a bottom reflector so that the fuel elements after once passing through the reactor core have reached the desired end burn-off conditions. Within or in the vicinity of that portion of the wall of the ceiling reflector and/or of the upper portion of the wall of the side reflector there are provided neutrons absorbing substances or additional substances reducing the speed of the neutrons.
