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.

A research program to control tritium in supercritical CO2 (SC-CO2) gas-cooled reactors is presented. This type of reactor is attractive because it offers higher thermal efficiency and lower reactivity with the primary coolant. This program consists of two activities; development of tritium permeation barriers in the heat exchanger tubes and development of tritium removal method from the SC-CO2. For permeation reduction, a glassy coating was developed as the tritium permeation barrier for the SC-CO2 system. Experimental results showed the physical and chemical integrity of the coating for 100 hours soaking in the SCCO2. Significant permeation reduction of 1/20 to 1/60 are obtained. But, further permeation reduction is desired through a new coating technique development, since the permeation reduction at lower temperatures is small.
