Other publications such as the history brochure: "SCK-CEN1952-2002 " highlight this event. rrihe annex to the Law Gazette of April 19, 1952 reads: "Het doel van het Studiecentrum voor de A Toepassing van de Kernenergie is alle navorsingen met betrekking tot de toepassing van de kernenergie uit te voeren en dergelijke onderzoekingen, met alle middelen te bevorderen en aan te moedigen - Le Centre d'Etudes pour ['application de 1'Energie nucleaire a pour objet de faire toutes recherches relatives aux appli- cations de 1'energie nucleaire, de promouvoir et d'encourager par tous moyens pareilles recherches" or in a free translation: " It is the task of the Research Centre on the Applications of Nuclear Energy to perform all research related to the application of nuclear energy and to promote and foster the like research by all means". Fifty years later, in the annex to the Law Gazette of November 1997, the basic mission is still the same. The bulk of our research concentrates on radiation protection, reactor safety and the back-end of the fuel cycle. The nuclear community from the very beginning addressed human health and societal problems with a pio- neer attention for the precautionary principle. On the one hand generalised public concern on science and technology and on the other hand, the nuclear expert, struggling with society, made perceive the need for a broader more holistic approach to address the social interaction. On initiative of the president of the Board, social sciences are associated to the basic technical nuclear research. This extended the well-established multidisciplinary approach of SCK-CEN. A structured collabo- ration became fully operational in 2001. Projects started on thematic demand from internal departments with interested supply of Belgian universi- ties: a technological aspects of nuclear science and technology in view of sustainability; si ethics and decision making in nuclear waste management a.o. transgenerational ethics and retrievability; socio-psychological aspects and local involvement; S3 law and liability more particular, the need for an optimal preventive approach and an appropriate com- pensation regime for nuclear activities; ss the role of the organisation in safety culture. In parallel a reflection group focussed on ALARA and the precautionary principle within the context of new trends in low dose effects, such as genetic susceptibility while another analyses expert attitudes and behav- iour and dilemmas in nuclear problem solving and communication. The reflections and research projects contribute to bridge in the polarised debate on nuclear in particular and on science and technology in general.
