According to the requirement of nuclear power developing in our country, we studied the manufacturing of fuel pellets with central hole: we determined the elastic after-effect of green pellets and the shrinkage after sintered through experiments; Based on it, we designed the manual model for pellets with cent.
根据我国核电发展的需要,对中孔环形燃料芯块的制造进行了研究:通过试验确定了生坯成形后的弹性后效,烧结后的收缩率;在此基础上设计了制备符合VVER项目技术条件要求的中孔芯块的手动模具;根据手动模具成形试验的结果,设计了适合批量生产,与旋转成形压机配套的自动成形模具。
