Nuclear Safety

Fuel cycle plants, research facilities, civil and defense nuclear programs: we have a comprehensive understanding of nuclear safety in all its forms and requirements.

 Need support?

The experience we have gained in risk management in the nuclear sector enables us to offer project management services to all operators in the civil and defense nuclear sectors.
