Abstract
HIFAR has now operated safely for more than 30 years, well beyond the original design expectations, with excellent availability for research and production of radioisotopes. The main reason for the longevity of HIFAR is the degree of conservatism of the design in the 1950's. The key components that affect the estimate of the useful life of HIFAR are presented. They include: the reactor aluminium tank (RAT), the graphite reflector and the reactor steel tank (RST) and shield cooling coils. An assessment of these components indicates that there are no foreseeable technical limitations to the operating life for the continued operation of HIFAR to 2025 at 10MW, in full compliance with safety requirements, provided that attention is paid to operating regimes, regular maintenance and replacement of other components. The costs of refurbishment of HIFAR and its facilities to the year 2025 are considerable. The paper concludes that the main risk from life extension is economic.
