FROM A VARIETY OF GRAPHITE BLOCKS SUPPORTING FLOOR FOR THE CORE OF A CORE REACTOR WITH SPHERICAL FUEL ELEMENTS

摘要

A supporting floor for the core of a nuclear reactor utilizes a plurality of independent support columns forming the floor of the reactor and resting on the bottom layers of the reactor. The support columns are surrounded by a side reflector which is in turn surrounded by a thermal side shield. Between the thermal side shield and the side reflector are disposed retaining means for maintaining the columns close together and preventing the formation of large gaps during operation.
