The Department of Energy today released its final environmental assessment (EA) and a proposed finding of no significant impact (FONSI) for the design, construction, and operation of the Molten Chloride Reactor Experiment (MCRE) at Idaho National Laboratory. The draft EA was released earlier this year, in March, for four weeks of public comments.

A tiny 200-kWt reactor the Department of Energy says would be the first critical fast-spectrum circulating fuel reactor and the first fast-spectrum molten salt reactor (MSR) could be built and operated inside the Zero Power Physics Reactor (ZPPR) cell at Idaho National Laboratory’s Materials and Fuels Center (MFC). Details included in the Molten Chloride Reactor Experiment (MCRE) draft environmental assessment (EA)released on March 16 for two weeks of public comment (later extended to four weeks, through April 14)—covered the potential environmental impacts associated with the development, construction, operation, and decommissioning of MCRE at INL, facilitated by the National Reactor Innovation Center (NRIC).

Orano, TerraPower get vouchers to study LEU+ transport and chlorine chemistry

The Gateway for Accelerated Innovation in Nuclear (GAIN) awarded vouchers to Orano Federal Services and TerraPower on June 22, giving them access to specialized facilities and expertise at Department of Energy national laboratories. Orano is partnering with Oak Ridge National Laboratory on a new technical study that updates the physical chemistry limits for the safe transport of uranium hexafluoride (UF6) gas enriched up to 10 percent in existing shipping containers, and TerraPower is turning to Los Alamos National Laboratory’s neutron testing capabilities to measure the properties of chlorine isotopes and determine how they will behave in the Molten Chloride Reactor Experiment (MCRE).
