[en] Among the domains dealt with in this programme, the 'Behaviour and Monitoring of Radionuclides in the Environment' sector particularly concerns the activities of this Symposium. The normal procedure followed consists in concluding research contracts with National Organizations and Universities (indirect action) studying priority problems and thereby bringing about efficient cooperation between the researchers working on them. These research projects are coordinated so as to avoid useless duplication of work and thereby use the available facilities to the best advantage. Consequently, these work projects stimulate national activities and supplement them in domains of common interest. A brief look at the subjects dealt with within the framework of the present programme, as well as the new orientations given to the 1980-84 suggested programme, will be presented in this paper

[en] The catalogue of European earthquakes with intensities higher than 4 contains some 20 000 seismic events that happened in member countries of the European Communities, Switzerland and Austria. It was prepared on the basis of already existing national catalogues and includes historical data as well as present-day data. All historical data are harmonized as far as possible to the same intensity scale (MSK-scale) to make them suitable for computerization. Present-day data include instrumental and macroseismic data. Instrumental data are expressed in terms of magnitude (Richter scale) while macroseismic data are given in intensities. Compilation of seismic data can provide a basis for statistically supported studies of site selection procedures and the qualitative assessment of seismic risks. Three groups of seismic maps illustrate the content of the catalogue for different time periods and different intensities

[en] This paper makes a brief comparison of the licensing processes for nuclear installations in European Community States, in particular concerning consultation of the public, the competent authorities and the period for the procedure in the countries considered. (NEA)

[en] An account is given of the inception, functioning and intentions of ESARDA (the European Sageguards Reasearch and Development Association) by a member of the Nuclear Materials Accounting Control Team at A.E.R.E., Harwell. This organisation will hold its first annual symposium in Brussels in April 1979. (U.K.)

[en] The safeguards system of the Member States of the European Community based on the Euratom Treaty is discussed here. It describes the special features of this system, its merits and difficulties, and it gives some indications as to further developments in the field

[en] A series of benchmark calculations has been performed to check inelastic analysis systems used within the European Community for Fast Reactor Problems. The context and history of these benchmarks are discussed and details are given of the latest, concerning a two-bar system under cyclic thermal load and increasing mechanical load. Six analyses showed varying agreement with experiment, generally satisfactory for deformation but less good for stresses
