Abstract：
Materials applied in nuclear environments such as fission or fusion power-plants face severe conditions. The irradiation by neutrons induces thermal loads and irradiation damage. Furthermore, coolants in contact with the materials induce corrosion, which is particularly challenging for liquid salts intended for the next generation of fission reactors. A new device (DICE) is installed at the 3.5 MV accelerator at DIFFER for the accelerated testing of such materials under combined irradiation and corrosion conditions. The DICE enables irradiation of samples at temperatures of up to 1050 K and in contact with liquid salts. An integrated shielding and a low power temperature control concept based on radiation cooling enables high-duty cycle application in a standard accelerator laboratory. Ion currents of up to 30 µA are possible with continuous irradiation. This work outlines the technical concept of the device and presents the first data.
摘要：
在核裂变或聚变发电厂等核环境中使用的材料面临严峻的条件。中子辐照会引起热负荷和辐照损伤。此外，与材料接触的冷却剂会引起腐蚀，这对于用于下一代裂变反应堆的液体盐尤其具有挑战性。在DIFFER的3.5MV加速器处安装了新设备（DICE），用于在辐照和腐蚀组合条件下对此类材料进行加速测试。DICE能够在高达1050K的温度下照射样品，并与液体盐接触。基于辐射冷却的集成屏蔽和低功率温度控制概念可在标准加速器实验室中实现高占空比应用。在连续辐照下，离子电流可能高达30µA。这项工作概述了设备的技术概念，并提供了第一个数据。
