由于铅冷快堆（LFR）的概念已经在第四代国际论坛（GIF）的框架，极大的兴趣集中在开发和测试的新技术，有关重液体金属（HLM）核反应堆。在此框架内，ENEA开发了欧洲较大的实验设施实验舰队之一，旨在研究HLM热工水力学，冷却剂化学控制，结构材料的腐蚀行为，并开发组件，仪器和创新系统，目前的工作旨在突出ENEA迄今为止在液态金属框架内开发的能力和竞争力GEN-IV LFR的技术。特别是，将考虑实际的设施群来描述正在进行的研发实验计划的概述：CIRCE、NACIE-UP、LIFUS 5、LECOR和HELENA。CIRCE（CIRColazione Eutettico）是目前在全球运营的最大HLM池设施。全尺寸组件测试，热分层研究，核安全和SGTR的运行和事故瞬态及整体试验可以研究大型水池系统中的蒸汽发生器管破裂事件。NACIE-UP（自然循环实验-升级）是一个回路，具有HLM初级和加压水次级侧以及在自然和混合对流中工作的250 kW功率燃料针模拟器。（用于聚变的锂）是一个专门用于HLM/水相互作用的分离效应设施。HELENA（HEAVY液态金属实验回路先进核应用）是一个纯铅回路与机械泵的高流量实验。LECOR（LEad CORrosion）是一个装有氧气控制系统的腐蚀回路装置，本文描述了在这些装置上进行的所有实验，描述了它们在GEN-IV LFR开发中的作用。
Since Lead-cooled Fast Reactors (LFR) have been conceptualized in the frame of Generation IV International Forum (GIF), great interest has focused on the development and testing of new technologies related to Heavy Liquid Metal (HLM) nuclear reactors. In this frame, ENEA developed one of the larger European experimental fleet of experimental facilities aiming at investigating HLM thermal-hydraulics, coolant chemistry control, corrosion behavior for structural materials, and at developing components, instrumentations and innovative systems, supported by experiments and numerical tools.The present work aims at highlighting the capabilities and competencies developed by ENEA so far in the frame of the liquid metal technologies for GEN-IV LFR.In particular, an overview on the ongoing R&D experimental program will be depicted considering the actual fleet of facilities: CIRCE, NACIE-UP, LIFUS5, LECOR and HELENA.CIRCE (CIRColazione Eutettico) is the largest HLM pool facility presently in operation worldwide. Full scale component tests, thermal stratification studies, operational and accidental transients and integral tests for the nuclear safety and SGTR (Steam Generator Tube Rupture) events in a large pool system can be studied.NACIE-UP (NAtural Circulation Experiment-UPgraded) is a loop with a HLM primary and pressurized water secondary side and a 250 kW power Fuel Pin Simulator working in natural and mixed convection.LIFUS5 (lithium for fusion) is a separated effect facility devoted to the HLM/Water interaction. HELENA (HEavy Liquid metal Experimental loop for advanced Nuclear Applications) is a pure lead loop with a mechanical pump for high flow rates experiments. LECOR (LEad CORrosion) is a corrosion loop facility with oxygen control system installed.All the experiment actually ongoing on these facilities are described in the paper, depicting their role in the context of GEN-IV LFR development.
