研究了辐照后的TRIO包覆燃料颗粒的抗压强度。为了比较，对17种辐照样品和10种未辐照样品进行了破碎试验。观察到紧凑制造后和辐照后的抗压强度都有所下降。结果表明，随着快中子注量和辐照温度的增加，材料的抗压强度降低。丙烷基PYC和丙烯基PYC包覆的颗粒由于辐照而产生的压碎强度变化的性质没有差别。辐照后抗压强度的下降不能很好地解释，但这可能是由于缓冲层从核层或IPyC层剥离造成的。
The crushing strength of irradiated Triso coated fuel particles was studied. The crushing tests were carried out on 17 kinds of irradiated samples and on 10 kinds of unirradiated samples for purposes of comparison. It was observed that the crushing strength decreased after compact fabrication as well as after irradiation. The crushing strength was found to decrease with increasing fast neutron fluence and irradiation temperature. No difference was seen in the nature of the change of the crushing strength as a result of irradiation between the particles coated by propane-derived PyC and propylene-derived PyC. The decrease in the crushing strength after irradiation could not be explained clearly, but it might have been caused by the debonding of the buffer layer from either the kernel or the IPyC layer.
