The High Flux Isotope Reactor (HFIR) is a nuclear research reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, United States.Operating at 85 MW, HFIR is one of the highest flux reactor-based sources of neutrons for condensed matter physics research in the United States, and it has one of the highest steady-state neutron fluxes of any research reactor in the world.
It operated from 1966 until 1969 (with six months down time to move from U-235 to U-233 fuel) and proved the viability of molten salt reactors, while also producing fuel for other reactors as a byproduct of its own reaction. [22] The High Flux Isotope Reactor built in 1965 had the highest neutron flux of any reactor at the time. [22]
In the last few years, samples of low-enriched uranium fuels have been tested for naval use at the High Flux Isotope Reactor at ORNL, according to a National Nuclear Security Administration report ...
The protons pass into a ring-shaped structure, a proton accumulator ring, where they spin around at very high speeds and accumulate in "bunches." Each bunch of protons is released from the ring as a pulse, at a rate of 60 times per second (60 hertz). The high-energy proton pulses strike a target of liquid mercury, where spallation occurs.

A High Flux Reactor is a type of nuclear research reactor. High Flux Isotope Reactor (HFIR), in Oak Ridge, Tennessee, United States of America, High Flux Australian Reactor (HIFAR), Australia's first nuclear reactor, High-Flux Advanced Neutron Application Reactor (HANARO), in South Korea. The High Flux Reactor at Institut Laue–Langevin in France.
Neutron science, using the Spallation Neutron Source, and the recently upgraded High Flux Isotope Reactor. Synthesis science, also called “science-driven synthesis,” facilitated by extensive and novel synthesis capabilities in the CNMS' first five scientific themes (described below) and by a new nanofabrication research laboratory.
