堆内辐照在线产氚氦冷陶瓷氚增殖剂包层球床组件热工流体力学计算分析

在研究堆内进行辐照在线产氚试验是ITER计划专项国内配套研究项目之一。本工作主要针对研究堆内辐照氦冷陶瓷氚增殖剂包层（简称陶瓷）球床组件的试验技术要求，评估辐照陶瓷球床组件设计方案的可行性。通过对不同的陶瓷球床组件结构参数和组件在堆内的不同辐照位置，进行热工流体力学设计计算，得到满足要求的入堆辐照陶瓷球床组件设计方案。

Thermal-hydraulic Calculation and Analysis on Helium Cooled Ceramic Breeder Pebble Bed Assembly for In-pile Irradiation & In-situ Tritium Extraction

In-pile irradiation & in-situ tritium extraction experiment is one of associated domestic research projects in ITER special program. According to the technical requirements of in-pile irradiation experiment of helium cooled ceramic breeder (ceramic) pebble bed assembly in a research reactor, the feasibility of the design for the in-pile irradiation & in-situ tritium extraction experiment of ceramic pebble bed assembly was evaluated. By conducting thermal-hydraulic design calculation with different in-pile irradiation channels, locations and structure parameters for ceramic pebble bed assembly, a reasonable design scheme of ceramic pebble bed assembly satisfying the design requirements for in-pile irradiation was obtained.
