The HFR at Petten has operated for more than 30 years, and has been continually updated during that period. The initial power has been increased from 20 to 45 MW, and the reactor vessel was replaced in 1984. Since then, the process of upgrading and replacement of ageing components has continued. The primary and pool heat exchangers, the beryllium reflectors, the nuclear instrumentation channels, the off-gas and gas monitor instrumentation, the ion exchanger drain and storage tanks have been replaced. The original overpower protection system has been renewed. Peripheral systems such as the outlet-line for the secondary cooling and the guaranteed power supply for the reactor have been repaired and refurbished, and the chlorine injection system has been replaced by the hypochlorite one. A stepwise upgrade of the control room is presently underway.
