Abstract In the conceptual design activity of advanced fusion neutron source A-FNS, a variety of test modules for fusion DEMO reactor are planned. In these modules, progresses of design activities on Blanket Nuclear Property Test Module (BNPTM) and Diagnostic and Control Device Test Module (DCDTM) were reported. The BNPTM is a module in order to evaluate accuracies of nuclear analyses of the DEMO blanket such as tritium production rate. The influences of the cooling water and test cell wall were evaluated in order to decide its design. The DCDTM is one to achieve irradiation data of functional materials on diagnostic and control devices such as mirror and window. It was clarified from its nuclear analysis that the neutron fluence obtained in the DCDTM was enough to investigate the accumulated irradiation effects on the materials. In addition to the irradiation tests on the fusion reactor materials, various neutron applications are planned at A-FNS. One of the applications is medical isotope production. We clarified that enough amount of the medical isotope molybdenum-99 could be produced in comparison with the demand in Japan by using Radio-Isotope Production Module (RIPM). The RIPM affects little influence on the fusion reactor material irradiation tests.

用于 A-FNS 的演示毯、诊断设备和 RI 生产的测试模块的概念设计

摘要 在先进聚变中子源A-FNS的概念设计活动中,规划了多种聚变DEMO反应堆的测试模块。在这些模块中,报告了全面核特性测试模块(BNPTM)和诊断和控制装置测试模块(DCDTM)的设计活动的进展。BNPTM 是一个模块,用于评估 DEMO 覆盖层的核分析精度,例如氚产率。评估冷却水和测试单元壁的影响以确定其设计。DCDTM 是一种在诊断和控制设备(如镜子和窗口)上获取功能材料的辐照数据。从其核分析中澄清,在 DCDTM 中获得的中子注量足以研究对材料的累积辐照效应。除了对聚变反应堆材料的辐照测试外,A-FNS 还计划进行各种中子应用。其中一项应用是医用同位素生产。我们澄清,与日本的需求相比,使用放射性同位素生产模块 (RIPM) 可以生产足够数量的医用同位素钼 99。RIPM 对聚变堆材料辐照试验影响不大。
