Abstract Lead-cooled fast reactors represent the forefront of Generation IV reactor concepts thanks to the technological development that has taken place over the last 20 years. Lead technology is object of steady attention in many Countries thanks to several development projects and an exponentially increasing industrial interest in recent years. One of the most advanced European projects is focused on the development of ALFRED (Advanced Lead-cooled Fast Reactor European Demonstrator) and is supported by the FALCON (Fostering ALfred CONstruction) international consortium. The goal is to construct a technology demonstrator which is also prototypic for a lead-cooled-based small modular reactor. To reach this ambitious goal, an important research, development and qualification infrastructure is planned in Romania, leveraging on the know-how cumulated within European and nationally funded endeavors. In particular, the infrastructure will support the scientific program with experimental campaigns dedicated to bridging the technological and scientific gaps, as well as to support the design and licensing of the reactor. This paper presents the configuration of the ALFRED reactor coolant system showing its present state of development and technological innovations. The current plant architecture provides for a thermal power up to 300 MWth and a coolant temperature range from a minimum of 390 °C to a maximum of 520 °C.

ALFRED 反应堆冷却剂系统设计

摘要 由于过去 20 年的技术发展，铅冷快堆代表了第四代反应堆概念的前沿。近年来，由于多项开发项目和工业兴趣呈指数级增长，铅技术一直是许多国家关注的对象。欧洲最先进的项目之一是专注于 ALFRED（先进铅冷快堆欧洲演示器）的开发，并得到 FALCON（Fostering Alfred CONstruction）国际财团的支持。目标是建造一个技术演示器，它也是基于铅冷却的小型模块化反应堆的原型。为了实现这一雄心勃勃的目标，罗马尼亚计划进行一项重要的研究、开发和认证基础设施，利用在欧洲和国家资助的努力中积累的专业知识。特别是，基础设施将通过致力于弥合技术和科学差距的实验活动支持科学计划，并支持反应堆的设计和许可。本文介绍了 ALFRED 反应堆冷却剂系统的配置，展示了其发展和技术创新的现状。当前的工厂架构提供高达 300 MWth 的热功率和从最低 390 °C 到最高 520 °C 的冷却剂温度范围。以及支持反应堆的设计和许可。本文介绍了 ALFRED 反应堆冷却剂系统的配置，展示了其发展和技术创新的现状。当前的工厂架构提供高达 300 MWth 的热功率和从最低 390 °C 到最高 520 °C 的冷却剂温度范围。以及支持反应堆的设计和许可。本文介绍了 ALFRED 反应堆冷却剂系统的配置，展示了其发展和技术创新的现状。当前的工厂架构提供高达 300 MWth 的热功率和从最低 390 °C 到最高 520 °C 的冷却剂温度范围。
