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 nonmechanical beam steering with phase conjugate (PC) mirrors, the scattered and reflected beams from a foam target are utilized. A scattering and reflection model has been made that coincides with the experimental results with an error between ±15%. In the case where four probe beams irradiated a foam target, the three-dimensional intensity distribution was simulated. The peak-to-minimum variation of the reflected plus the scattered energy per unit solid angle was [approximately]20% of the average energy.The PC beam direction needs to compensate for target motion (v [approximately] 300 m/s) to accurately irradiate an injected target with laser beams in the method of beam steering with PC mirrors. The compensation with four-wave mixing utilized as a PC mirror is shown. A PC beam can be adjusted by properly setting the angle between two pump beams.
