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.

The n = 2 mode rotational instability, which appears on a field-reversed configuration plasma produced by a theta pinch, is stabilized by a helical quadrupole field. The critical strength of the field to stabilize the instability is obtained as a function of pitch angle of the helical coil a rad/m. Typically, the plasma in the α = 6 winding field is stabilized by about one-fifth of α = 0 field strength. To physically explain such a good effectiveness of the helical field, the rotation speed of the plasma iso measured by a Doppler shift of a carbon V 2270.9-Å line. However, the clear explanation to the helical effect is not yet given.
