The High Flux Reactor (HFR) at Petten is a 45 MW light water cooled and moderated research reactor which has been in operation for more than 30 years. The aluminium reactor vessel was replaced in 1984; since then low-cycle fatigue testing has been carried out on non-irradiated specimens from stock material of the new vessel, and fracture mechanics (crack growth and fracture toughness) and tensile strength testing programmes have been performed on materials from both old and new vessels. An irradiation damage surveillance programme (SURP) was also set up in 1985, testing material specimens taken from selected irradiation positions regularly during the operating life of the new vessel.
