The second phase of the co-ordinated project MIRAGE (Migration of
Radionuclides in the Geosphere) was launched by the CEC in 1986 /!/. It
puts together cost-sharing research contracts with organisations in the
Member-States, as components of the third Community R&D programme on
radioactive waste management and storage (1985-1989), as well as
relevant activities of the own programme of the Joint Research Centre
(JRC) at Ispra. About 40 firms and laboratories are therefore
participating in this project; the increasing involvement of Third
Countries linked to the Community by co-operation agreements in the
field of radioactive waste management is a noteworthy feature of
MIRAGE.
At a first plenary meeting (Brussels, March 24-25, 1988) the work
programme and preliminary results were presented, and subsequently
published /2/. The second plenary was held in Brussels on March 16-17,
1989; as for the first meeting, summary reviews of the work done in the
four research areas of the project for 1988 were prepared and presented
by the following experts :
J.I. KIM, for research area "Geochemistry of Actinides and Fission
Products in Natural Aquifer Systems"
A. AV0GADR0, for research area "In-situ Migration Experiments and
Development of Measuring Techniques"
N.A. CHAPMAN, for research area "Natural Analogues"
G. de MARSILY, for research area "Calculation Tools".
The various comments received, and discussions held at the meeting,
were subsequently taken into account by the experts for the preparation
of the final versions of their reviews, as presented in this report. The
Commission gratefully acknowledges the valuable contributions of the
experts and participants in the meeting.

— VI SUMMARY TABLES OF CONTRACTS REVIEWED
The following tables bring together the various cost-sharing
contracts of the second phase of the MIRAGE project, classified under
the four research areas, as well as the companion work carried out at
the Joint Research Centre, Ispra. For the sake of simplification, full
contract numbers (i.e. FI1W/00XX) have been abbreviated as "XX".
Contributions of laboratories of Third Countries to benchmarks such
as COCO and CHEMVAL are listed in the summary reviews pertaining to the
respective research areas.
