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.

To obtain a fast estimation of the total impurity density distribution in a poloidal cross section from soft X-ray (SXR) measurements during quasi-stationary phases, the possibility that ionization equilibrium may have little influence on the emissivity profile of Ni and Fe in the core region of tokamak plasmas is investigated. Preliminary and encouraging results that support this assumption under certain conditions are found. A simplified approach aimed at computing a satisfactory estimation of the total density of a unique and identified impurity directly from an absolutely calibrated SXR tomographic inversion is implemented. An example of application to a previously and independently performed transport simulation of a Ni injection in Tore Supra is then given.
