对陶瓷球床组件的堆内辐照情况进行物理计算分析有助于改进辐照装置的设计，完善辐照方案。按照堆内辐照陶瓷球床组件的实验技术要求，采用MCNP程序对陶瓷球床组件在不同孔道内的辐照情况进行了产氚量、产氚速率、发热量等计算。计算结果表明：采用天然丰度6 Li的陶瓷球床组件在考验孔道内以半功率辐照能满足实验技术要求；如要采用满功率辐照，则需将组件中心位置提升至活性区中平面以上23 cm处。

In-pile irradiation facility design of ceramic pebble bed assembly and irradiated scenario could be improved with physical calculation and analysis . According to the experimental and technical requirement of in-pile irradiation ,tritium production ,rate of tritium production and nuclear heat were calculated for ceramic pebble bed assembly in different vertical tubes with MCNP code . The results show that the pebble bed assembly with natural enrichment of 6 Li which is irradiated in test tube with half power or with full power at the location of 23 cm above reactor core mid-plane could satisfy the experimental and technical requirement .
