IN JUNE, EDF ENERGY ANNOUNCED it had completed the 49,000-metric-tonne concrete basemat for the second EPR reactor at Hinkley Point C in Somerset. The milestone was achieved “on schedule”, despite the coronavirus pandemic and a reduction of “more than half” in the number of workers on site since March. Completion came less than a year after the basemat was finished for the first 1630MW reactor at the Hinkley Point. C power plant, which is owned by EDF Energy (66.5%) and China General Nuclear Corporation (33.5%). The target date for this first key milestone (referred to as J0) was set four years ago. Completion now marks the transition from below- ground activity to the construction of permanent reactor buildings above ground. EDF Energy says Hinkley Point C2 benefited from experience gained on the first identical unit, which “led to significant increases in productivity through steps such as increased use of prefabrication.” This approach is expected to benefit the proposed follow-on project at Sizewell C in Suffolk, which has recently applied to the UK government for planning permission.
