Research & Development
Scanscot Technology participate in national and international Research & Development (R&D) undertakings on a regular basis, and is today heavily involved in several state-of-the-art projects. This include projects directed to the Nuclear Power Industry, but also projects managed by Regulatory Bodies and International Organizations.
R&D projects include interpretation and development of design requirements and guidelines, validation and improvement of structural analysis and simulation methods, and development of testing and evaluation methods.
Scanscot Technology is heavily engaged in various committees and projects related to development of requirements for structural design.
- Member of the American Society of Mechanical Engineers (ASME) Committee,
- Member of the American Concrete Institute (ACI) Committee,
- Member of the European Organisation of Standardisation (CEN) Workshop,
- Author of Design of Nuclear Buildings (DNB).
DNB is a new Design Guidance for safety-related concrete structures at nuclear power plats and other nuclear facilities. The guide include detailed sections e.g. for the design of reactor containments and design for seismic events. The publisher of DNB is the Swedish Radiation Safety Authority (SSM).

Scanscot Technology is also the author of other reports and design guidelines on reactor containments, missile impact, seismic design and anchoring to concrete.
Scanscot Technology has been involved in several R&D projects and benchmark studies with the purpose to validate existing simulation methods and to develop new or enhanced methods for structural modeling and analysis.
Examples on studied fields:
- Static and quasi-static accidental loading, e.g. increased pressure and temperature inside reactor containments
- Dynamic vibrational accidental loading, e.g. seismic response analysis and vibrations induced by missile (aircraft) impact
- Local dynamic accidental effects, e.g. damage caused by impacting missiles
- Local failure of concrete structures, e.g. anchoring to concrete
- Time-dependent losses of pre-stressed concrete structures, e.g. pre-stressed reactor containments
Examples of benchmark studies:
- ISP 48 (reactor containments, ultimate capacity – OECD NEA)
- SPE 3 (reactor containments, leak-tightness – USNRC and AERB)
- Vercors (reactor containments, time-dependent effects – EDF)
- SMART (seismic response – CEA)
- IRIS (missile impact – OECD NEA)
- ANKARM (anchoring to concrete – SSM)
- ASCET (degradation of concrete – OECD NEA)
Scanscot Technology continuously participate in research & development projects with the purpose to develop, or gain confidence in using, combined methods for testing of concrete structures including numerical simulations.
Examples of such projects include:
- Aging of reactor containments
- Non-destructive testing of concrete reactor containments
- Extraction of structural modal dynamic characteristics from experimental test data
- Updating of numerical models using experimental test data
For applications related to non-destructive testing, we work closely with leading experts such as Force Technology and BAM.
