The European Union should maintain a diversity of its sources of energy supply, to avoid depending on a limited number of sources (green paper). Nuclear fission is likely to continue to contribute substantially to the European energy mix.

Important issues remain, among them a broadly agreed approach to nuclear waste management:- behaviour of radwaste in disposal (and in particular long lived actinides)- treatment of radwaste: partitionning, waste matrices, transmutation targets…- better use of fissile resources (optimisation of current concepts, innovative concepts…)

Actinide Sciences play an important role in that context. But:- Actinide sciences became less attractive for students,- Safety requirements heavy, Research expensive,- Fragmented scientific community…

Pool parts of major facilities, primarily from the core group institutes, for the benefit of joint research projects involving members of the Network.

Operate these pooled facilities as a multi-site user facility, and make it accessible to all members through a selection procedure by a Scientific Advisory Committee.

- improve regulations and procedures to allow or ease access to and use of some facilities, including mutual acceptance of safety certificates already obtained by researchers at their home institutions or at other ACTINET institutions,

- preserving compatibility between users, in particular between academic ACTINET users and industrial partners, including potential issues as confidentiality, planning…

- facilitating accommodation for ACTINET users, - implementing or adapting the necessary trainings for ACTINET

researchers, and last but not least, - finding and implementing a viable economic model for the operation

of the multi-site user facility in the long term.

Scientific projects will be

proposed by collaborations within the Network

evaluated by the Scientific Advisory Committee: scientific excellence, impact on integration, and impact on applied issues of importance

accepted by the Executive Committee

financially supported with the European grant for integration

ACTINET : Joint Research Projects



Applied Issues: Assessment of waste management strategies:

geological disposal of long-lived radioactive wastes, partitioning and transmutation of long-lived radionuclides on an industrial scale,

>> behaviour of materials containing actinides (fuels, waste matrices, transmutation targets), and

>> chemistry of actinides in geochemical environments and in partitioning processes. Support to operation and improvement of existing nuclear plants:

increased fuel burn-up, longer fuel cycles, extension of plant life, power up-rating,

>> fuel behaviour under reactor conditions and after irradiation. Assessment of innovative concepts for better use of fissile resources:

new fuels and associated waste management.

>> requires considerable amount of experimental and modelling work.

Actinide materials under and after irradiation.

develop contacts with the An sciences community, and to further postgraduate studies at other laboratories.

Specialisation at post-doctoral level closer interaction between scientists at post-doctoral level and the whole community.

ACTINET Summer School, held every year alternately in Karlsruhe and Marcoule.

>> ACTINET Summer School 2004 planned in Marcoule and Avignon 17-19 June, on “Thermodynamics and Kinetics of Liquid-Liquid Extraction”.
