  1. First delivery of permanent equipment for Hinkley Point C made via Combwich Wharf

    November 15, 2019

    Combwich Wharf has facilitated the delivery of four large tanks. The tanks are a part of the design for the diesel generators and formed the first piece of permanent equipment to arrive at Hinkley Point C via Combwich Wharf.

    Constructed in a factory in the Czech Republic, the tanks set off on their journey in mid-September, travelling by a combination of sea and road to arrive at their final destination, Hinkley Point C, at the end of October. Along the way, the tanks passed through Slovakia, Bratislava and Rotterdam.

    The marine leg of the journey was undertaken by Osprey – a specialist logistics business based in Portishead, Bristol. John O’Connor, Osprey’s Commercial Director, said: “Our team has been on site, on hand, and on board from start to finish. Getting the equipment delivered safely was our priority; getting the right people involved from the outset meant we were working in real partnership, all the way.”

    As each tank is 6.5m in diameter and 10m long, the final leg of their journey involved being carefully delivered under escort between the village of Combwich and Hinkley Point C site.

    Seawall completed at HPC

    The seawall structure is now complete end to end. It’s taken teamwork, innovation, working around high tides, strong winds and wintery heavy swells to complete it.

    The team often had to stagger their working hours to make progress within tidal windows. The logistics of working on a narrow platform with limited working room or laydown also presented challenges – this was solved by developing schemes for cranes to work on the foreshore and using ramps to aid access.

    Nigel Clarke, KierBAM Engineer, said: “I’ve been involved in the construction of the seawall from the start, when we were still working on the beach. It’s been one of the most exciting projects I’ve worked on during my career.”

    The seawall in numbers

    • Total volume of material excavated was 180,000m3
    • 50,000m3 of concrete poured
    • Largest single pour of 1,404m3
    • Total of 308 pre-cast wave return units installed

    Unit 1 Nuclear Island progress

    Good progress continues to be made on the first unit’s nuclear island structure, with the construction of the fuel handling building now well underway. The structure will comprise of 10 main levels and will house nuclear safety class systems and mechanical systems.

    The first concrete pour has been completed for one of the largest sections – a 30m-high, free-standing structure. Some 38 tonnes of rebar has been placed and more than 126m3 of concrete poured so far.  In total it will need 123 tonnes of rebar and 386m3 of concrete.

    Construction of the two independent emergency diesel buildings has also started, with 550 tonnes of rebar placed for slab one and 150 tonnes placed for slab two.


  3. New apprentices at Hinkley Point C push total to more than 500

    November 7, 2019

    Today we mark another important milestone for the Hinkley Point C Project with 500 apprentices being trained so far.

    The latest group of 12 apprentices joining Hinkley Point C have helped push the total number of apprentices on the project beyond 500.

    Hinkley Point C Apprentice, Lauren Withers.

    They include Lauren Withers, aged 23 from Bridgwater. She said: “I grew up in Bridgwater so it’s fantastic to have the opportunity on my doorstep to stay in the area and develop my career without having to move away.  My previous job was at a local bank branch and now my apprenticeship will take my skills to the next level and help me progress into management accounting.”

    Hinkley Point C has already helped to create over 8,500 jobs with thousands more to follow over the coming years.  Today’s milestone shows the project is on track to create 1,000 apprenticeships during construction. The experience will be repeated for people in Suffolk and East Anglia at the proposed follow-on project at Sizewell C.

    The latest intake of apprentices are also benefitting from EDF Energy’s award winning support to many of its contractors via direct transfer of its apprenticeship levy. Working with the National Apprenticeship Service, EDF Energy is now able to use 25% of its apprenticeship levy funds to help Hinkley Point C contractors like HOST create new apprenticeship programmes.

    Work starts on first intake tunnel

    The first of the Hinkley Point C’s (HPC) three tunnel boring machines, operated by Balfour Beatty, has successfully started the construction of intake tunnel 1.

    There will be three water cooling tunnels which will feed water to the power station when its operational.

    Balfour Beatty is using its factory at Avonmouth to create the 38,000 segments that will make up the 6,000 rings needed for the three tunnels.

    When built, the intake tunnels will be 6m in diameter and 3.5km long and draw 120,000 litres of water in from the Bristol Channel every second.

    The tunnel boring machine working on tunnel 1 has been named Mary by local primary school children after Lyme Regis palaeontologist Mary Anning.

    Twelve operators, including a pilot, run the 1,200-tonne machine, with support teams based at the surface. The multi-discipline team includes apprentices, graduates, quantity surveyors, ground surveyors and temporary works engineers.

    Laying the foundations for new electricity substation

    Work is now underway to create the new electricity substation that will plug HPC into the National Grid. Led by National Grid, a team from Linxon has been working on the building’s foundations. As part of the wider project to bring power from HPC to UK homes and businesses, National Grid will use new T-pylon designs for the first time anywhere in the world for the 57km connection between Bridgwater and Avonmouth. In total, 13 new pylons will be built nearby to connect the power station to the national network. James Goode, National Grid Senior Project Manager, said: “We’re pleased and proud to be bringing HPC’s electricity to the network. This is also a fantastic opportunity to inspire the next generation of engineers and young people across the region to take up STEM careers.”

    Fourth concrete batching plant completed

    The fourth and final batching plant has been set to work, mixing high-quality nuclear standard concrete. Mechanical and electrical works on the batching plant were completed at the end of September. Since then, the team responsible for delivering the huge volumes of concrete needed have put it through its paces and it’s now supplying concrete that is Quality Related Activity (QRA) approved. Peter Abel, Chief Materials Officer at Bylor, said: “We’ve done a lot of the learning with the first three plants and we’ve got it down to a rapid process now with plant 4.”

    Like its fellow batching plants, the fourth can produce 70m3 of concrete per hour. Plants 1, 2 and 3 have supplied more than 450,000m3 of concrete to the Project so far. Peter added: “Having a fourth plant now gives us total flexibility.”

    Big Carl ready for next big milestone

    Sarens SGC-250

    The world’s largest crane is ready to start work at the Hinkley Point C nuclear power station site. Able to stand up to 250m tall, “Big Carl” can reach higher than the tallest tower at London’s Canary Wharf and can carry 5,000 tonnes in a single lift.

    The new Sarens SGC-250 crane was shown off on-site at Hinkley Point C today where it will be used to lift large prefabricated sections of the power station into place. The crane was developed to support the growing trend towards modularisation in big construction – and its deployment allows Hinkley Point C to exploit this innovation on a large scale.

    The crane’s huge size and capacity allows large components to be built in covered factory conditions on site, improving quality and saving time. The success of prefabrication has already been proved during construction of the two operational EPRs built by EDF and CGN at Taishan in China. Its use at Hinkley Point C is another example of the innovation made possible by experience gained and applied from other nuclear construction projects.

     

    Pipes in progress

    Hinkley Point C’s Tier 1 contractor Socea Denys completed its biggest concrete pour to date in August, placing 1,900m3 of concrete for the Unit 1 inlet cooling water pipe. Construction of the cooling pipe means Bylor can start building the Unit 1 turbine building later in the year. The name ‘CRF’ comes from the French term ‘Circuit de Refroidissement’, meaning cooling water circuit.

    Balfour Beatty has made significant progress in the construction of the cooling water tunnels, as the first permanent segment ring has been installed into intake tunnel 1. The ring is made up of six segments, all of which have been built by the Balfour Beatty team in the Avonmouth segment factory.

     

    Liner cup takes shape

    A specialist welding machine was used to perform 36 plasma welds for the first liner cup. The liner cup forms one of the five parts of the the first reator’s containment liner.

    The high-quality welding process ensures the liner cup bottom is completely flat. Plates are then cut to complete the circular cup.

     

    Pump House progress

    The Bylor Heat Sink team is making progress constructing the Pump House. More than 9,000m³ of concrete has been poured to complete the first raft slab, which will reinforce and strengthen the Pump House and its cooling water system. A network of steel cylinder concrete pipes (SCCP), which will eventually transport seawater from the Bristol Channel to the condenser via the Pump House, has arrived on Site. The first concrete pour for the Unit 2 raft in the Heat Sink has begun and walls are being constructed for the 54m-high Pump House.
