    摘要： A CORE CLAMPING SYSTEM FOR USE WITH NUCLEAR REACTORS WHEREIN BIMETALLIC ELELMENTS ARE PLACED AROUND A CORE SO THAT AT HIGH TEMPERATURE A FLUX CONDITIONS THEY ACT TO EXERT AN INWARDLY DIRECTED CLALMPING FORCE ON A PREDETERMINED CLAMPING PLANE THEREBY CONTERACTING THE TENDENCY FOR THE CORE TO EXPAND UNDER THOSE CONDITIONS AND MAINTAINING CONSTANT CORE GEOMETRY.

    摘要： A core clamping system for a nuclear reactor that utilizes a cylinder connected to a core support structure of the reactor and which is slotted axially to develop a plurality of cantilever beam-spring segments that act upon the core elements at a determined clamping plane to accommodate for expansion and contraction of the reactor core and thereby induce a negative contribution to the power coefficient of the nuclear reactor.

    摘要： A nuclear reactor core-locking device which holds the fuel assembly loosely for refueling and tightly against vibration or other adverse movement under operating conditions. A coreretainer band surrounds and is spaced from the core at assembly. The retainer band is made from material having a lower coefficient of thermal expansion than the core structural material so that when operating temperatures are reached the core expands into contact with the band and becomes effectively locked into place.
