00:04Welcome back to Hinkley Point C for the latest update from the power station that will meet
00:09around 10% of Britain's current electricity demand. Winter and summer, night and day for
00:14decades to come. Above me is a lid of our first nuclear reactor. It needs to be kept extremely
00:20clean and is now inside the reactor building being prepared for installation. It's an incredible
00:25piece of engineering. Let's go and see what's been happening around the site since our last tour.
00:31At Hinkley Point C we're building two identical units side by side. Civil construction teams have
00:37nearly finished all unit one's buildings and have now turned their attention to unit two,
00:42using all their experience to do the job even better second time around. That means here in unit
00:48one new teams have moved in to fit the huge amount of equipment, supports, pipes, valves and cables
00:55needed to make a nuclear power station work. It's what we call the MEH phase.
01:02Since our last visit we've installed all four steam generators. They're 520 tons each
01:08and they'll use the reactor's heat to make steam for our turbine. We've also installed the pressurizer,
01:15another essential piece of kit that allows water to be superheated without boiling.
01:19We're now welding this into what we call our primary circuit. Thank you, good morning.
01:26While there are lots of giant components, we're also fitting thousands of smaller components.
01:32Like these supports, just some of the 220,000 that we're installing. All this section of pipe,
01:38just six meters of the 700 kilometers needed across both units. All this cable, we're installing 10,500
01:47kilometers like it, enough to go a quarter of the way around the world. Getting MEH underway after
01:54civil construction is a big logistics and organizational challenge in any project and the start has been
02:00tough going. Now we're really getting moving and gaining momentum by adopting an industrial mindset,
02:05taking the process that work best and scaling them up. You all right? You want to show us into bunker
02:11six?
02:12So this is where we're doing all the clamps and our last. Yeah. This is the welding bays.
02:18That means opening on-site factories like this and new logistics centers where we organize everything
02:23we need. We're making access easier and doing more modular work off-site that allows us to build as
02:29safely and efficiently as possible. Let's go and look at the turbine hall.
02:39Here we're installing the giant parts needed for the world's largest turbine, the Arabelle. Behind me,
02:45we're installing the rotor, one of its first spinning parts. But before this power station can generate
02:51electricity for the country, it first needs electricity of its own. And that's where the electrical building
02:56comes in. Here we're well on with the cables, systems and equipment needed to start taking electricity
03:08from the national grid. That will happen later this year, bringing the plant and machinery to life.
03:14Allowing us to ramp up testing and make sure everything works as it should. Our cooling water
03:20comes from the Bristol Channel through the tunnels we've now finished. When we're ready to introduce
03:25the cooling water onto the site, we'll release these 250 ton plugs at the end of each of the three
03:30tunnels.
03:32We'll be the first power station on the Severn to have fish protection with three separate systems,
03:36more than any other power station in the world. We're now tunnelling our fish return system and
03:42testing of our fish deterrent shows it works even better than we had hoped. So what about Unit 2?
03:50On Unit 2 we're getting ready to install our second reactor pressure vessel, which arrived on site in
03:55January. But this time around we'll use our huge crane big car to do the job. It's another of the
04:00innovations that are helping us to move 20 to 30 percent faster. Like these huge modular buildings
04:06that we're lifting in, with equipment already installed, all the more efficient ways we've found
04:11to build the turbine hall. So that's the latest from Hinkley Point C. We're at peak construction.
04:17There's so much happening here and we're really looking forward to a summer of fantastic engineering
04:22and building, as we work to get this power station online for Britain to give us the reliable homegrown
04:28power we all need. See you next time.
04:33We'll see you next time.
04:34We'll see you next time.
04:39We'll see you next time.
04:39We'll see you next time.
