EVALUATION OF ASEISMIC INTEGRITY IN HTTR CORE-BOTTOM STRUCTURE .3. STRUCTURAL INTEGRITY OF CORE SUPPORT POST COMPONENT

Component testing of the core support post for the high temperature en gineering test reactor (HTTR) was carried out to verify its structural integrity using full-scale and 1/2-scale models. The compressive frac ture load was measured at room temperature under the conditions of pos t inclination up to about 1 degree, cyclic load up to 200 times and ox idation up to about 30% of oxidation weight-loss. In this paper, the e ffects of post inclination angle, cyclic load and oxidation weight-los s of this component on the compressive fracture load were discussed an d the fracture load was compared with the design load of the HTTR.
