Hinkley Point C nuclear power station

Hinkley Point C nuclear reactor, UK, still under construction - AP

Looking at the thumbnail for this puzzle, I thought it might be a stadium, but it's not. I didn't know anyone (except maybe the French) were building nuclear reactors these days, but here we are.

Hinkley Point C nuclear power station is under construction in Somerset, England. The project is financed by EDF Energy and China General Nuclear Power Group. EDF is a French company. China General Nuclear Power Group is a Chinese state-owned energy corporation. Is the UK becoming a colony?

EDF has several pictures of this project. This one caught my eye:

The cranes are placing a 5,000-tonne water intake head onto the seabed

There are tunnels leading from the power plant out into the bay and the intake (and outlet) heads are placed on the seafloor to preserve the integrity of the opening into the tunnel. The concrete block suspended between the two cranes is the intake head. To give you a sense of scale of this scene, the intake head is 150 long and 25 feet tall.
