Centrale nucléaire de Hinkley Point C
La centrale nucléaire de Hinkley Point C (HPC) est l’un des projets les plus importants et les plus complexes technologiquement en Europe.
HPC est la première centrale nucléaire construite au Royaume-Uni depuis une génération, et sa construction nécessite une main-d'œuvre hautement qualifiée et les meilleures solutions de construction et d'ingénierie.
The HPC Project is located in Somerset, South West England, and will consist of two nuclear reactors capable of generating 3.2GW of low-carbon electricity.
The new power station is being constructed in the same area as the existing Hinkley Point A and B stations. The former has ceased operation for quite some time, while the latter is decommissioning in 2022.
Dextra s'est vu confier la fourniture d'épissures mécaniques de renfort en béton pour des pièces du HPC, notamment la coque de protection contre les chocs aéronautiques du réacteur.
More than 2.5 million Griptec couplers are supplied for the construction of HPC.
Griptec is designed to comply with the most stringent project specifications, and has proven to be a popular system of choice for EPR nuclear power stations, having been used for the construction of the Flamanville 3, Taishan 1, and Taishan 2 power stations.
The Griptec mechanical splice consists of two steel sleeves which are swaged onto the end of the reinforcing bars by a specific machine that was designed and patented by Dextra.
Cette machine à sertir intègre un test de traction non destructif systématique. Griptec est le seul système de coupleur qui assure un contrôle qualité automatique de chaque barre traitée.
Besides Griptec couplers, Dextra is also supplying 3 million headed bars to the project. These are reinforcing bars that are bent on one side and fitted with an anchorage head on the other side and are used for the transverse reinforcement of concrete slabs, rafts, and walls. They allow a much faster and safer site installation than conventional double-bend bars.
When complete, HPC will provide low-carbon electricity for around six million homes.
