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.

A neutron spectrometry system is proposed to provide information about the ion plasma temperature profiles in the International Thermonuclear Experimental Reactor (ITER) cross section. The system consists of two fanlike arrays of spectrometers and collimators positioned horizontally (20 channels) and vertically to the machine (10 channels). The devices are intended for use in both the deuterium-deuterium (D-D) (physical) and deuterium-tritium (technology) phases of ITER operation. For the D-D phase of operation, a system using NE-213 liquid scintillators and a 3He ionization chamber is proposed. A new high-performance neutron spectrometer based on recoil-proton energy measurements by means of a semiconductor detector and neutron spectrum unfolding is proposed for the technology phase.
