Stellaria applies to build a molten salt reactor prototype in France
French advanced reactor developer Stellaria has formally submitted an application with the French government for authorization to build a prototype of its fast breeder molten salt reactor concept, known as Stellarium.
The company, which spun out of the country’s Alternative Energies and Atomic Energy Commission (CEA) and Schneider Electric, filed an application for authorization to create (DAC) for the reactor with the government minister in charge of nuclear safety, making it the first French start-up to submit an application with the authorities for a fast-neutron reactor.

In the last three years, fuel failures have been experienced in research reactors at Oak Ridge National Laboratory (ORNL) and the National Institute of Standards and Technology (NIST). The first of the events occurred in November 2018 at the ORNL High Flux Isotope Reactor (HFIR) resulting in the deformation of several fuel plates in the outer fuel element. The second related event occurred in February 2021 at the NIST Center for Neutron Research (NCNR) Reactor where damage occurred in a single fuel element. While neither event resulted in significant radiological exposure, each of the affected reactor facilities paused operations to review fuel fabrication, training, operations, quality assurance, and other aspects potentially contributing to the events. This session will be a panel that will discuss these events, the associated causal analyses, planned corrective actions, and lessons learned.
