Abstract: The invention relates to a reactor with a system or systems for controlling the regulation and the cutoff of a power output on the basis of neutron absorption using motile neutron absorber bodies. The invention also relates to a method of regulating the output of a nuclear reactor, and to absorber bodies that are adapted to the method and to a regulating system. According to the invention, spherical absorber bodies such as SAS are used in guides in the reflector in such an arrangement that a maximum neutron absorption is achieved adjacent to areas of a maximum output of the core and a reduced or zerovalent absorption in areas where the output of the core is reduced.

Abstract: The invention relates to a pebble bed reactor with a core cavern filled with fuel element pebbles and bounded by reflector material. Fuel element pebbles traverse the core cavern due to the effect of gravity. There is downward or upward flow of cooling gas through the core cavern. The cooling gas pipes provided for this purpose extend laterally above the base of the cavern bottom. Cooling gas can be conveyed without problems through the fuel-element pebble bed for long periods of operation.
