Workshop on "Radiological characterisation for decommissioning", Studsvik, Sweden 17-19 April 2012

Publicerad: 8 november 2011
The OECD Nuclear Energy Agency (NEA), in co-operation with Studsvik Nuclear AB, the Swedish Radiation Safety Authority (SSM), Swedish Nuclear Fuel and Waste Management Co (SKB) and AB SVAFO, is arranging a workshop on Radiological characterisation for decommissioning and dismantling

Relaterat material

The objective of the workshop is to highlight, examine and discuss strategic issues related to radiological characterisation of nuclear facilities to facilitate their safe and efficient decommissioning. The workshop will be a forum for

  • learning about current practices,
  • exchange of experiences of both successful and less successful projects,
  • discussion of best practice and needs for improvement, and
  • development of networks in the area of radiological characterisation, waste management and decommissioning.

The workshop is arranged in coordination with an ongoing NEA WPDD project on radiological characterisation for decommissioning. The outcome of the workshop will be captured in workshop proceedings and in the final NEA WPDD project report.


A three-day programme is planned. A short introduction by representatives from Studsvik and OECD/NEA will start the workshop followed by presentations by invited speakers from international organisations.

Four topical sessions will cover issues relating to

  • Characterisation of materials and systems
  • Characterisation of rooms and buildings 
  • Characterisation of land and groundwater
  • Software support, record keeping, quality assurance and logistics

Each session will contain 3 - 5 presentations and group discussions. Each session will be concluded with a short analysis of the presentations and the outcome of the group discussions.

The workshop will also hold a poster session with topics as above.

After the formal closing of the workshop, half a day is dedicated for guided tours at the Studsvik and SVAFO facilities. It will be possible to visit waste management facilities, the reactor decommissioning project and materials technology laboratories.
