What we do in nuclear

New build

We are one of the largest providers of project and engineering services to the UK nuclear market and have been involved with some of the UK’s largest nuclear construction projects. We support reactor vendors and developers from green-field site to power generation to ensure new build facilities are well planned, designed and constructed, complying with the complex industry legislation.
