Information and organizational issues were also considered. Establishment of a web-site for EERRI to ensure general information dissemination and a discussion board was decided (public platform for the information templates mentioned above). Regarding activity coordination and monitoring the task implementation between EERRI meetings, a monthly and/or bi-monthly conference call among the members was agreed. The IAEA representative was asked to manage these issues and to host a web-site for the EERRI coalition. 3. Summary of the first year activity of EERRI Summarising the first year activities of the EERRI coalition, a formalized and regular dialogue among the RR operators can be mentioned as the most important achievement. Beyond the sharing of information, a kind of joint thinking and planning has been started since the first meeting. It is expected that this process will strengthen and mature. The coalition defined the strategic goals and the fields of cooperation as follows: − − Strategic goals: based on the synergy effect of the existing facilities to offer improved services for the user communities which will prepare themselves for the time of using leading-edge <strong>European</strong> facilities. Fields of cooperation: = Education and training = Neutron beam application = Isotope production = Irradiation of fuel and materials/PIE Reviewing the activities and the implementation status of the action items, the first year summary of the EERRI and results can be summarised in the following tables (see Tables 1 to 6): Table 1. Meetings and communications Meeting Place and date Meeting subject Participants countries/persons Budapest, 28-29 January 2008 Vienna, 4-5 September 2008 Main achievements Exploratory meeting 6/13 Establishment of EERRI Define strategic goals and cooperation fields Formulate Memorandum of understanding Designate contact person Outline work plan with 7 action items Plenary meeting supported by IAEA TC RER/4/029 7/14 Official announcement of the existence of EERRI coalition Monitor implementation of action items Designate coordinators for each cooperation field Outline work plan with 9 action items 5 40 of 455
