Fusion energy is an area of active development and innovation worldwide, with many design concepts studied, each exhibiting a range of technical challenges. A significant portion of technical challenges will be unique for a given design concept; however, there are several overarching challenges that any design must address to some degree. These include tritium handling and the tritium cycle; materials and their survivability in the high-energy neutron environment of D-T fusion; neutronics and the validation of nuclear data; remote handling and maintenance activities; and integrated holistic approaches to fusion plant design. This paper provides an overview of these aspects for magnetic and inertial fusion approaches with a view to highlighting commonality and the benefits of shared knowledge that this may bring. This article is part of a discussion meeting issue 'Prospects for high gain inertial fusion energy (part 2)'.
聚变能是全球积极发展和创新的领域，有许多设计概念正在研究中，每个概念都展示了一系列技术挑战。许多技术挑战将是特定设计概念所独有的；然而，任何设计都必须在一定程度上解决几个总体挑战。这些挑战包括氚的处理和氚循环；材料及其在 D-T 聚变高能中子环境中的生存能力；中子学和核数据的验证；远程处理和维护活动；以及融合工厂设计的整体综合方法。本文概述了磁约束和惯性约束聚变方法的这些方面，以期突出共性和共享知识的好处。本文是讨论会议议题“高增益惯性聚变能的前景（第 2 部分）”的一部分。
