Join the heroes in nuclear

The climate change is one of the greatest challenges of our time. We must cut down on fossil emissions. At the same time, we need to electrify our society even more.

That is why we need nuclear – the most effective fossil free energy source there is.

And we need to keep developing the nuclear industry. We need to innovate. We need to digitize. We need to apply breakthrough technologies.

So we are joining our forces to find the heroes we need for all of this to happen. The heroes in nuclear.

We hope that you are one of these heroes. Your engineering skills, your enthusiasm and your ability to team up with us may be just what the future generations need.

Welcome to our trainee program.
