Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

The application in TEXTOR of an externally controlled radial electric field Er, imposed by means of an electrode, has allowed to ascertain many aspects of the physics of the creation of Er and of its effect on radial transport. Radial conductivity was shown to depend on parallel viscosity with the latter's nonlinear response to Er providing the basic ingredient for Er bifurcation, typical for L- to H-mode transitions. Simultaneous time and space resolved measurements of Er and of the plasma flows in the edge by means of a newly developed inclined Mach probe have allowed to further substantiate the role of parallel viscosity and of neutral collisions in the damping of rotation. The causal role of grad Er in bringing about the transport changes has been proven by showing that the field shear is spatially correlated with and temporally leads the density gradient, as well as by comparison with theoretical modeling.
