Abstract

The High Flux Reactor (HFR) in Petten has been in continuous and successful operation for over 30 years. Used mainly in material testing, the installation has been kept up-to-date by the replacement of ageing components. In 1984, for example, the HFR was shut down for the replacement of the aluminium reactor vessel which had been irradiated over the previous 20 years. The new reactor vessel concentrated on the requirement that the reactor should be able to operate provided no critical defects are in evidence. In order to assess the HFR vessel integrity, knowledge of both material properties and likely defect presence and size must be obtained. Material property testing is carried out to obtain data on fatigue life, fatigue crack growth, fracture toughness and hardness, strength and ductility, while an in-service inspection (ISI), performed on a 3-yearly basis, incorporates ultrasonic, eddy current, dimensional and visual testings.
