<p><P>PROBLEM TO BE SOLVED: To provide a reactor core restriction mechanism of a high temperature gas reactor with excellent heat resistance capable of stably keeping on giving fastening force to a fixed reflector block for over a nuclear reactor life period without causing deterioration of the fastening force resulting from creep even under a high temperature environment. <P>SOLUTION: In a reactor core restriction mechanism 100 for tightening a fixed reflector block 60 arranged in the surroundings of a reactor core 64 of a high temperature gas reactor, a restriction band 10 consisting of a ceramic long fiber material is provided in the outer periphery of the fixed reflector block 60. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
