核技术的鉴定和验证对于聚变示范 (DEMO) 和发电厂来说是一项艰巨的任务。对于涉及 14 MeV 中子和高温工作条件的恶劣辐射环境的先进设计尤其如此。本文概述了美国开发的独特资格和验证流程，提供了进入完整聚变环境的唯一途径，重点关注美国最著名的毯式概念（双冷却 PbLi (DCLL)）以及在专用测试模块中测试新一代结构和功能材料。此类活动的场所是拟议的聚变核科学设施（FNSF），该设施被视为美国聚变路线图的重要组成部分。已开发出分阶段的毯子测试策略，以在 FNSF D-T 操作的每个阶段测试和增强 DCLL 毯子性能。 FNSF 中包含的材料测试模块 (MTM) 对于在相关聚变环境中测试未来更先进的材料的广泛样本至关重要。 MTM 最重要的属性是相关的 He/dpa 比率 (10-15) 以及与国际聚变材料辐照设施 (IFMIF) 和欧洲演示中子源 (DONES) 中提供的 10-500 mL 范围相比更大的样本体积。
The qualification and validation of nuclear technologies are daunting tasks for fusion demonstration (DEMO) and power plants. This is particularly true for advanced designs that involve harsh radiation environment with 14 MeV neutrons and high-temperature operating regimes. This paper outlines the unique qualification and validation processes developed in the U.S., offering the only access to the complete fusion environment, focusing on the most prominent U.S. blanket concept (the dual cooled PbLi (DCLL)) along with testing new generations of structural and functional materials in dedicated test modules. The venue for such activities is the proposed Fusion Nuclear Science Facility (FNSF), which is viewed as an essential element of the U.S. fusion roadmap. A staged blanket testing strategy has been developed to test and enhance the DCLL blanket performance during each phase of FNSF D-T operation. A materials testing module (MTM) is critically important to include in the FNSF as well to test a broad range of specimens of future, more advanced generations of materials in a relevant fusion environment. The most important attributes for MTM are the relevant He/dpa ratio (10–15) and the much larger specimen volumes compared to the 10–500 mL range available in the International Fusion Materials Irradiation Facility (IFMIF) and European DEMO-Oriented Neutron Source (DONES).
