Abstract: This paper describes selected equipment and expertise on fuel irradiation testing at the High Flux Reactor (HFR) located in Petten, The Netherlands which is in use for next generation reactor concepts such as the six Generation IV International Forum systems. The HFR is owned by the European Commission which also uses it for its scientific R&D programs. Reactor operation and commercial exploitation are performed by NRG who has become also the license holder in 2005. The reactor went first critical in 1961 and holds an operating license up to at least 2015. While in the past the HFR was obviously focusing on Light Water Reactor (LWR) fuel and material irradiation tests in support of safety assessments and later service life extension programs of LWR, it also played a decisive role since the 1970s in the licensing process of High Temperature Reactor fuel, notably in the German HTR development program. A variety of tests related to fast reactor development in Europe was also carried out. Over the past ten years, the HFR was progressively used for next generation fuel and material tests, in particular for V/HTR fuel, fuel for closed fuel cycles (U-Pu and Th-U fuel cycle) and transmutation, as well as for other innovative fuel types. As such, the HFR constitutes a significant European infrastructure tool for the development of next generation reactors and serves for the licensing of fuel and materials of planned next generation demonstrator projects. Experimental facilities addressed here comprise V/HTR fuel tests, a coated particle irradiation rig, and tests on fast reactor, transmutation and thorium fuel. The rationales for these tests are given, results are provided and further work is outlined.
