The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is a high performance research reactor used to produce transuranium isotopes and perform material irradiation studies. HFIR was operated for about 20 years prior to its shutdown in November 1986 and has remained shutdown while the results of safety studies are completed and reviewed. This paper highlights results from ongoing studies which have revisited system thermal-hydraulic safety limits with present day analytical tools and experimental investigations. Long term decay heat removal requirements have been examined as well as the response of the system to small break loss of coolant accidents (SBLOCA). 10 refs., 1 fig.
