Lappeenranta University of Technology
(LUT, Lappeenranta, Finland)


Lappeenranta University of Technology (LUT) was established in 1969 as a national university of technology. LUT is state-run and financed by the Ministry of Education. Lappeenranta University of Technology is specialized in technology and economics. About 5000 students study in the various degree programmes offered by the university, and about 900 new students are admitted each year. There are about 500 postgraduate students, and 900 members of staff.

The most outstanding feature of the university is the way in which it has successfully integrated expertise in technology and economics. LUT's location in town Lappeenranta very near the border between the EU and Russia has also had a major impact on the university's activities and orientation.

In Finland a new nuclear power plant unit, Olkiluoto 3, is under construction, the nuclear repository test site ONKALO is being excavated, environmental impact assessments for a further NPP are going on. LUT has responded to the challenge of training majority of the nuclear engineering professionals needed in Finland. The students graduating from our laboratory have good basic knowledge in all disciplines related to nuclear energy applications and energy and power plant technology, and special knowledge in the following branches of nuclear technology: radiation protection, safety issues, function and system knowledge in nuclear power plants, computer code modeling of nuclear power plants, nuclear reactor and radiation physics, nuclear waste and environmental effects. Students have possibility to acquire the ENEN certificate (EMSNE) by studying 20 ETCS in co-operative universities of LUT.
