Modelling sequential biosphere systems under climate change for radioactive waste disposal

Objective

The project will provide a scientific basis to assess the safety of radioactive waste repositories in deep formations, with regard to the possible long-term impacts. Two complementary strategies will provide representation of future climate changes using respectively analysis of extreme situations and a continuous simulation over the next 1,000,000 years. Climate and vegetation models of different spatio-temporal scales will therefore be used to simulate the time series of climate and vegetation in various European areas. These results will be used to derive the nature of the human environments (i.e. the biosphere systems) through which radionuclides, coming from the repository, may transfer to Man. Finally these exposure and migration pathways will be described for three selected biosphere systems using two different approaches: a discrete one commonly used and a more innovative transitional one.
Work Package 1: Consolidation of the needs of the participating European waste management agencies in order to harmonise requirements for performance assessment requirements;
Work Package 2: Development of methodology to provide climate models for regional discrete climate states and associated vegetation for periods of 100,000 years or more;
Work Package 3: Development of a methodology to provide climate models for continuous representation of regional climate states and associated vegetation for periods of up to 100,000 years;
Work Package 4: To adapt the output from the climate models developed in Work Packages 2 and 3 to the representation of biosphere systems under different climates to the requirements of performance assessment models;
Work Package 5: To disseminate the results of Work Packages 1 to 4 through a final seminar and project documentation.

In the first seven months of the project, work is nearly completed on Work Package 1 (together with Deliverables 1 and 2), and work has been initiated on Work Packages 2, 3 and 4.
