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.

An experiment on the separation of hydrogen isotopes has been carried out by using a thermal diffusion column with a “cryogenic-wall” cooled by liquid nitrogen. The separation factor was compared with that of a ordinary column cooled by water, and the separation factor for the “cryogenic-wall” column is higher than that for the “water cooled wall” column. Moreover, the separation factor obtained by a 473 K operation of the hot wire in the “cryogenic-wall” system was found to be greater than that by 1073 K operation. Probably because the isotopic exchange reaction between H2 and D2 was suppressed in 473 K operation; there was no HD component observed in this case, while an equilibrium amount of HD component was immediately detected in 1073 K operation.
