Superstructure takes shape in turbine hall
After 36 hours of continuous concrete pouring, the project team responsible for the turbine generator table at conventional island Unit 1 ended last year’s construction programme on a high note. With the large reinforced concrete structure in place 20m above the turbine hall base, the focus now is to complete the superstructure that will hold the turbine responsible for generating low carbon electricity for millions of UK homes. The project team will now construct the lower and upper retaining walls surrounding the building, while steelwork will be erected by Bylor’s contractor, William Hare Ltd. Once completed, the building will be handed to GE for the installation of the components and associated equipment required for electricity generation.
MEH Alliance working on water tanks
The MEH Alliance, which is delivering the Mechanical, Electrical and HVAC (heating, ventilation and air-conditioning) works on site, is continuing with the installation of pipework and supports within the raw water storage liaison gallery and temporary works for the next level of the electrical building. With the recent handover of the Unit 1 safeguard building, the site team has started the installation and welding of the mechanical supports to the embedment plates, with more than 30 completed to date. Preparation works are currently under way to begin the installation of the balance of plant tanks, which will house demineralised water for the operation of the power station. The first phase of work will include the MEH team laying out the tank floor, which comprises 32 different floor plates and 10 backing straps.
Ceiling completed on key safety feature
Close collaboration between EDF, Bylor and Teesside-based contractor Darchem has helped successfully complete the installation of the ceiling on the emergency feedwater system tank within the Unit 1 safeguard building, marking another significant safety landmark on the project. The metal ceiling was fabricated and welded on site, before being carefully lifted into the. The next phase of work will involve welding the tanks into position and constructing the reinforced concrete walls around them, so they’re fully enclosed within the safeguard building.
