U.K. consents to Hinkley Point B decommissioning
The U.K. government’s Office for Nuclear Regulation has granted EDF Energy formal consent to decommission the Hinkley Point B nuclear power plant in Somerset, England. The two-unit advanced gas-cooled reactor was permanently shut down in August 2022, and site owner EDF applied to ONR for decommissioning consent in August 2024.

The influence of a few parameters on the possibility of reaching ignition in the Ignitor device is analyzed using a 1½-dimensional equilibrium transport code. The models adopted for electron and ion thermal diffusivities scale with the net power input to the plasma components. No auxiliary heating is considered besides that due to alpha particles. In the operative scenario examined, the plasma current (Ip = 10 MA) and the toroidal field (BT = 11.1 T) are maintained for 4 s. The importance of density profile shaping is pointed out together with the influence of current density peaking. Sensitivity to specified assumptions is also analyzed and the limit values, still guaranteeing ignition, for different parameters are determined.
