24170186406_cf0073efc6_kThe High Flux Isotope Reactor, as it looked on Sept. 4, 1967, about a year after it attained full power — 100 megawatts at the time — at Oak Ridge National Laboratory. The research reactor’s power level was scaled back to 85 megawatts following concerns in the late 1980s about embrittlement of the pressure vessel.
