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.

In Cu-30 Zn alloys during irradiation with 2-MeV electrons from a Van de Graaff generator, the electrical resistivity first decreases due to radiation-enhanced ordering and then increases due to the formation of very small interstitial clusters. The activation energy during irradiation for both processes is approximately Qirr = 0.37 eV and is interpreted as half of the migration energy of freely migrating interstitials. For irradiation temperatures below 75°C, a second resistivity increase is found that is attributed to the formation of stable interstitial clusters. The observed radiation-enhanced diffusion rates below ambient temperature are many orders of magnitude smaller and larger than those predicted by the one- and the two-interstitial models, respectively, and these rates are in agreement with the predictions of the modified two-interstitial model.
