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 multiplication of 14-MeV neutrons in bulk beryllium has been measured using the manganese bath technique. Values of the multiplication have been obtained for beryllium samples of four thicknesses. Detailed calculations of the multiplication and all the systematic effects were made, utilizing a highly detailed three-dimensional model with the Monte Carlo program MCNP. The Young and Stewart and the ENDF/B-VI evaluations for beryllium were utilized in the analysis. Both data sets produce multiplication values that are in excellent agreement with the manganese bath measurements for both raw and corrected values of the multiplication. We conclude that there is no real discrepancy between experimental and calculated values for the multiplication of neutrons in bulk beryllium.
