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 millimeter-wave system of the remote steering launcher at the upper port level is composed of beamlines that are rated for 2-MW continuous-wave operation at 170 GHz. In each beamline, a torus window is located between the entrance to the in-vessel square corrugated waveguide and the steerable mirrors in the launcher back end. In the reference design, the maximum steering angle of 12 deg imposes a 27-mm off-center beam shift to the window disk center, which in turn leads to asymmetrical heating of the window. This raises particular concerns of enhanced thermomechanical stresses in the window and in the metallic window cuffs. In order to qualify the optical, mechanical, and thermohydraulic design, high-power short-pulse and thermohydraulic tests were performed using a prototype chemical vapor deposition diamond torus window developed and manufactured at Forschungszentrum Karlsruhe. It was proven that arcing did not occur even under maximum millimeter-wave power levels available (up to 0.53 MW) and that the millimeter-wave beam profile was fully maintained. A test facility allowed thermohydraulic studies of the window cooling system with parameters characteristic for component cooling water loops at ITER (pw = 1.0 MPa, Tw = 40°C).
