Background – Nuclear energy R&D

In Finland nuclear energy R&D consist of In Finland nuclear energy R&D consist of research in three major areas:research in three major areas:

nuclear power plant safety (reactor safety), 39 %

waste management, 50 %

fusion, 10 %

In nuclear power plant safety nearly 40 % of In nuclear power plant safety nearly 40 % of research is done in public research programmesresearch is done in public research programmes

SAFIR – The Education

SAFIR is an important forum for education of SAFIR is an important forum for education of nuclear experts in Finlandnuclear experts in Finland

Education takes place via research work in the Education takes place via research work in the SAFIR projectsSAFIR projects

Education is a continuous processEducation is a continuous processNew experts into the nuclear field - largely via tutoring by the old experts

New challenging tasks for the old experts – old experts have to acquire new skills
