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.

Activation analysis was performed for the outboard (o/b) and inboard (i/b) blanket and shield of ITER. The options of using PCA or Tenelon were assessed. The o/b blanket and shield qualify as class C LLW. If Tenelon is used, it qualifies as class A waste. The i/b shield by itself qualifies as class C waste only if Tenelon is used. If PCA is used, then class C qualification can be realized if the i/b and o/b shields are disposed of together. The total amount of 14C produced in the coolant is 4650 Ci for LiNO3 and 54 Ci for LiOH. The Be/SS/W i/b shield results in a decay heat much less than that in an all W shield. Under adiabatic heat-up conditions, the PCA structure can withstand a L0CA and after one day the temperatures do no exceed 700°C.
