摘要： A gas-cooled high temperature reactor is provided having a core filled with spherical fuel elements, in combination with a graphite side reflector including at least one nose-like projection protruding radially into the reactor core from said graphite said reflector, the at least one nose-like projection including at least one vertically disposed cavity adapted to receive discrete absorber material elements introduced into said reactor core as well as a vertically disposed continuous opening which permits communication between said cavity and the core of the reactor, said opening having a maximum width adjacent said cavity which is less than the minimum dimension of said discrete absorber material elements in order to prevent passage of said elements into said continuous opening from said cavity.

摘要： An automatic switch of this type includes a switch latch for interrupting current, an overload tripping device and a short-circuit current tripping device for acting on the switch latch to trigger a current interruption. Generally there is also included at least one main contact device having at least one stationary contact and at least one movable contact, a movably supported contact lever attached to the at least one movable contact, and at least one arc quenching device associated with each main contact device. The improvement according to the invention includes a combination of an additional armature system having a magnet coil, a magnet core, a magnet armature and a striker pin. The striker pin is operable for directly striking the at least one movable contact lever and for lifting the at least one movable contact from the at least one stationary contact for a given limited time in the event of short-circuit currents, and the short-circuit current tripping device is in the form of a selective protection tripping device.
