Explore the challenges in implementing and optimizing countermeasure strategies during emergencies and how simulation models can aid in decision-making. Discussion highlights various phases of an emergency, importance of plant status information, and the role of simulation models in preparedness and response phases. The need for tools aligned with ICRP recommendations and ongoing development efforts by ARGOS and RODOS consortiums are also emphasized.

Outcome of Topic 2: Challenges in the practical implementation of countermeasure strategies and their optimisation during an emergency and how simulation models can support this
Outcomes of the discussion • The discussion focused on the usage of tools in the various phases of an emergency, having a clear distinction between the preparedness and the response phase • There was little discussion about the technical content of the proposed new screening tool; the reason was that the content of the proposed tool was not known to several members of the audience and there was not enough time to discuss this in detail • The discussion focused on the experience from the Japanese case, where most decisions were based on the plant status – in the early phase and monitoring in the later phase
Outcomes of the discussion cont. • Concern was raised that simulation models might be only suitable to support decisions on the time frame of days but not months and years • In the emergency phase the group felt that information on the plant status and from monitoring is important to verify simulation models • On the other hand the group favoured the use of simulation models in the preparedness phase as an input for the implementation of strategies
Outcomes of the discussion cont. • There was nearly no discussion about the need to have a tool to develop strategies in accordance with the ICRP recommendations taking into account not individual measures, but all exposure pathways • Personal statement of the chair of WP2 • In this way the discussion reflected the current thinking with the experience of using the individual measures since more than 20 years – at least taking into account statements from the more active participants • The ARGOS and RODOS consortiums will continue in the development of the new tool, informing the NERIS partners about their ideas and using the feedback received
