氦冷卵石床 (HCPB) 毯是为欧洲 DEMO 动力堆进一步开发的两个概念之一。由于渗透主要结构材料而导致的氚泄漏是聚变技术的主要问题之一。在目前的工作中，已经评估了等离子体和第一壁冷却剂之间的第一壁中的氚渗透和存量。考虑了温度梯度、表面条件、同位素效应以及离子和中子引起的缺陷捕获对氢同位素渗透和库存的影响。
The Helium Cooled Pebble Bed (HCPB) blanket is one of the two concepts to be further developed for a European DEMO power reactor. Tritium leakage due to the permeation through the main structural materials constitutes one of the main problems of the fusion technology. In the present work, the tritium permeation through and inventory in the first wall between the plasma and the first wall coolant has been evaluated. The influence of temperature gradient, surface conditions, isotopic effect, and trapping in ion- and neutron-induced defects on the hydrogen isotope permeation and inventory has been considered.
