Description

VTT is a broad-scope contributor in international nuclear research. We provide contract services internationally - about 20% of commercial assignments are coming from abroad. VTT is independent and has a solid reputation as the leading Technical Support Organisation of the Finnish nuclear safety authority (STUK) for more than 30 years.

The VTT Centre for Nuclear Safety facility executes a wide range of research and testing activities on materials utilized in nuclear power plants and spent fuel final repository systems, particularly activities involving radioactive substances.A portfolio of standardized and accredited methods as well as sophisticated tools and techniques are available.Nuclear power plant operators and suppliers can have their materials tested for mechanical and chemical performance, and analysed for compositional and microstructural characteristics, both in the new, unused condition, as well as after operation in the plant environment or after accelerated aging or radiation exposures.

The Centre for Nuclear Safety in Espoo hosts our brand-new multi-disciplinary laboratories, research facilities and expertise, all under one roof.:

  • 200 professional staff members offering international-class research and broad technological backgrounds
  • Nuclear-focused knowledge, methods and software for safety analysis, engineering, simulation, testing, and training
