Reporting period April 2001 - September 2001
Work package 1 Activities :
The objective of the first Work Package (WP1) has been to consolidate approaches and develop an understanding of the requirements for representing climate change in performance assessments (PA) as perceived by the BIOCLIM participants. This was achieved through the collaboration between the organisations with responsibility for disposing of national radioactive waste and the regulatory agency within the BIOCLIM consortium. Information has been collated and summarised in two separate documents on:
The first document (Deliverable 1) summarises the mechanisms causing climate change, provides a synopsis of how environmental change is currently treated in such assessments, and summarises the lessons learned to date from such applications. The second document (Deliverable 2) provides present day narrative pictures together with palaeological climate and vegetation data for four European regions where deep radioactive disposal sites might be developed. This work will contribute to future Work Packages as a basis for understanding how past climate changes have influenced the current regional biosphere systems in order to lay the basis for modelling how radionuclides might migrate and accumulate in future biosphere systems following release from a repository.
Work package 2 Activities :
The purpose is to simulate the future environment, more precisely climate and vegetation, of European areas within which disposal sites may be established. A hierarchical strategy has been set up.
Work package 3 Activities :
The objective is to obtain a set of very long term climatic simulations in the future, and thus provide a continuous description of possible future climate changes. The activities are still currently concerning the development and the validation of the tools to be used in these long term experiments.
Work package 4 Activities :
Although WP4 is not due to commence until Month 25, discussion and proposals are already being made. WP4 will use the knowledge and understanding derived from the preceding work packages to identify and describe the potential effects of environmental evolution on biosphere systems. Methods to evaluate the effects of environmental change will be agreed that follow closely the methodology adopted for the IAEA BIOMASS programme.
