多年来，欧洲(欧盟)聚变方案已经认识到，对未来聚变动力反应堆所用材料的鉴定需要中子源。该设施的建设和开发目前被认为处于示范的关键阶段。这一问题促使欧盟在IFMIF/EVEDA(工程验证和工程设计活动)项目中取得的成果的基础上开展了IFMIF-DONS(国际聚变材料辐照设施--演示定向中子源)设施的设计和工程活动，并利用在IFMIF/EVEDA(工程验证和工程设计活动)项目中取得的成果，该项目目前是在欧盟-日本关于更广泛的聚变方法的双边协定的框架内进行的。IFMIF-DONS工厂的这些活动和研发工作目前正在与聚变能源组织直接合作的EUROFusion联合体的工作包框架内进行。这些活动的主要目标是巩固设计和基础技术基础，以便尽快为IFMIF-DONS建设做好准备。本文介绍了在设计工作的头几年获得的主要工程成果，如最近发布的IFMIF-DONS初步工程设计报告所示，重点强调了设计从以前阶段的演变和在不久的将来需要进一步发展的关键问题。还简要介绍了拟议的欧洲设施所在地(西班牙格拉纳达)。
The need of a neutron source for the qualification of materials to be used in future fusion power reactors have been recognized in the European (EU) fusion programme for many years. The construction and exploitation of this facility is presently considered to be in the critical path of DEMO. This issue prompted the EU to launch activities for the design and engineering of the IFMIF-DONES (International Fusion Materials Irradiation Facility-DEMO Oriented Neutron Source) facility based on and taking profit of the results obtained in the IFMIF/EVEDA (Engineering Validation and Engineering Design Activities) project, presently conducted in the framework of the EU-Japan Bilateral Agreement on the Broader Approach to Fusion.These activities and R&D work for the IFMIF-DONES Plant are presently taking place in the framework of a work package of the EUROfusion Consortium, in direct collaboration with the Fusion for Energy Organization. The main objective of these activities is to consolidate the design and the underlying technology basis in order to be ready for IFMIF-DONES construction as early as possible.The paper presents the main engineering results for a generic site obtained during the first years of design work, as indicated in the recently released IFMIF-DONES Preliminary Engineering Design Report, making emphasis on the design evolution from previous phases and on the critical issues to be further developed in the near future. The proposed European site to host the facility (Granada, Spain) is briefly introduced as well.
