About 600 experiments and roughly 500 users were affected by the nearly year-long shutdown of the High Flux Isotope Reactor at Oak Ridge National Laboratory, the lab said Thursday.
HFIR, which is used for research and isotope production, restarted October 29, 2019. It had been shut down since November 13, 2018, after an elevated radiation level was detected in the reactor’s primary cooling system.
Reactors users who had approved proposals when HFIR was shut down have been running those experiments since it restarted in the fall, according to a response to questions provided by ORNL spokesperson Morgan McCorkle on Thursday. The backlog is expected to be completed by the spring.
The shutdown did not affect the production of plutonium-238, but it did delay the production and distribution of some medical and industrial isotopes, the lab’s response said.[Read more…]
