Conversion of High Flux Isotope Reactor at Oak Ridge delayed until 2020

Frank Munger reports that the High Flux Isotope Reactor at the Oak Ridge National Laboratory will continue to use HEU fuel until February 2020. Earlier, the conversion date for the reactor was set to September 2016, and earlier yet - to 2014. Explaining the delay, ORNL referred to the challenge of developing all-new high-density LEU fuel and budget constraints.
