INL makes first fuel for Molten Chloride Reactor Experiment
Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.

Several methods for sampling the Klein-Nishina distributions for scattered photon secondary energy are studied to determine an optimum sampling technique useful from 1 keV to 100 MeV. A commonly used approximate inverse method is evaluated for accuracy by analytically comparing the exact and approximate sampling distributions. This method, several rejection methods, and an exact direct sampling method are evaluated for computing speed on several different computers.
