Decision analysis of clean-up actions in inhabited areas;Concluding report of the nine facilitated workshops conducted in seven European countries in the EVATECH project

Nine facilitated workshops on selection of strategies to clean-up of contaminated inhabited environments were run in seven European countries within the EVATECH project undertaken as part of the key action Nuclear Fission in the fifth EURATOM Framework Programme (FP5). The Aim of the workshops was to clarify the information and decision support needs of decision makers a few days after a radioactive release from a nuclear accident when considering the choice and implementation of recovery actions in inhabited areas. The workshops were conducted in 2003 and 2004 in UK, Germany, Denmark, Poland, Slovak Republic, Belgium and Finland.

The workshops, in which relevant stakeholders together focused on the same problem, were the first attempt, on a European scale, to use decision analysis tools together with RODOS and ARGOS to test their usability and to identify further development needs of the decision support systems. The decision analysing tool used was WEB-HIPRE, which was chosen to be the tool used with RODOS.

The workshops demonstrated that difficult trade-offs in relation to the emphasis given to public perception and political acceptability (so called subjective attributes) against more objective criteria, such as radiation health effects and costs, have to be done. It was also demonstrated that this kind of facilitated workshop is useful in later phases of a radiological emergency situation when stakeholders have enough time to make necessary preparations and to seek adequate support from their own organisations. It was also noticed that RODOS together with WEB-HIPRE can be utilised in training and in exercises where what if scenarios can be exercised.

From a technical point of view, the workshops clearly showed that improvements are still needed in the RODOS and ARGOS systems and in their capability to produce the necessary data needed in decision analysis. It is recognised that some of the information required to aid the decision making process will not be available from such systems in the event of an accident, e.g. local issues, acceptability of different countermeasure options etc.
