INL's Advanced Test Reactor has a unique serpentine fuel arrangement, which allows researchers to simultaneously test materials under varied conditions. The characteristic blue glow is due to Cherenkov radiation, which is emitted when a charged particle such as an electron passes through the cooling water at a speed faster than the speed of light in the water.

    Excellent picture! I have seen "the glow" in real life only once at the High Flux Reactor Petten, Netherlands. Hope to see it again some time.
