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.

This study was conducted to explore the feasibility of rapid setting cement (RSC) as an agent of immobilization for certain elements such as fission products or radioactive materials through evaluation of the setting time, apparent porosity, bulk density, pH value, conductivity, compressive strength, and compositions. Two different cylindrical sample groups were created. The first group was a mixture of the cement powder with deionized water (DIW) and different concentrations of Ce (0, 2, 5, 7.5, and 10 wt%). The second group included the cement powder, artificial seawater (ASW), and same Ce concentration patterns. Samples were analyzed by X-ray diffraction (XRD), fluorescence analysis (XRF), and scanning electron microscopy including energy-dispersive X-ray spectroscopy. The results showed that the final setting time and compressive strength of RSC with both solutions (DIW and ASW) decreased as Ce content increased while opposite trends were observed for the apparent porosity and bulk density of RSC under the same concentration effect. As salt contents increased, the pH decreased while the conductivity increased gradually. The XRD patterns revealed that two newly identified phases were reported, namely CeAl11O18 and Ce4.667 (SiO4)3O. The XRF results showed uniform distribution of Ce concentrations within RSC with both solutions (DIW and ASW). The morphology of matrix samples showed that the existence of Ce distributed on the pore wall or clustered with Si, Al, Mg, K, P, Fe, and O.
