Terrestrial Energy, Schneider partner on molten salt reactor
Terrestrial Energy and Schneider Electric are teaming to deploy Terrestrial Energy's integral molten salt reactor (IMSR) to provide zero-emission power to industrial facilities and large data centers.
The companies signed a memorandum of understanding in April to jointly develop commercial opportunities with high-energy users looking for reliable, affordable, and zero-carbon baseload supply. Terrestrial Energy said that working with Schneider “offers solutions to the major energy challenges faced by data center operators and many heavy industries operating a wide range of industrial processes such as hydrogen, ammonia, aluminum, and steel production.”

Magnetic divertors have been proven successful in minimizing plasma/wall interactions and in leading to high-confinement regimes in tokamaks. This suggests that similar benefits may occur in a reversed-field pinch (RFP) fitted with a divertor. Previous experiments using divertors in an RFP have used a poloidal field divertor configuration such as those used in tokamaks. This study investigates another approach, a toroidal field divertor (TFD). A simple model of a poloidally symmetric TFD is presented and used in a three-dimensional magnetohydrodynamic code to study the response of the plasma to the large poloidal m = 0 perturbations caused by the divertor coils. It is found that the topology of the RFP-TFD system is much more complex than had been expected. The three-dimensional DEBS code shows that the divertor will not hinder the formation of a reversed toroidal field in the plasma, although the dynamics of its formation is altered when toroidal effects are considered. The plasma develops flows and currents in the throat of the divertor in response to the vacuumlike divertor fields. These flows and currents tend to restore the force-free character of the plasma.
