Beginning of November 2015, HARMONE started as integral part of the European OPERRA project. It will last for 18 months and consist of six research partners (HMGU, IRSN, KIT, PHE, SCK•CEN, UCEWP) and three advisory organisations (BfS, IAEA, RIVM). HARMONE aims to reduce scientific, methodological and operational gaps identified in the strategic research agendas of the four European Platforms in the area of radiation protection and issued as TOPIC 2 of the OPERRA-2014 Call: “Spatial and temporal environmental modelling and human dose assessment after a nuclear accident”.
HARMONE aims to harmonize and expand the modelling approach of the European decision support systems (DSS) RODOS and C3X/SYMBIOSE. To achieve this goal, the project will deal with many possible release scenarios, environmental characteristics and shortcomings on information in the early phase of an emergency. To adapt the models better to the environmental conditions all over Europe, geographical and climatic influences on regional fishing and farming practice will be assessed. It is then planned to divide Europe into regions with common radioecological characteristics, collect the relevant data and implement them as generic information in the DSS. Aquatic, groundwater, snow melt, forest and terrestrial models in these DSS will be updated with the new data sets and their implementation improved.
Uncertainty analysis of the SYMBIOSE models can be done to identify relevant exposure pathways, parameters and FEP for the different scenarios and regions. Results from this process may suggest improvements in monitoring strategies which are also part of HARMONE. With this information, recommendations for the monitoring of radiological parameters necessary for the DSS after radiological incidents can be developed. Finally, the project will develop a knowledge data base and guidance that allows, according to the first event description, to propose a first management strategy to reduce doses and highlights potential issues for the dose assessment.
