Dr. Suikkanen has over 10 years of experience in nuclear engineering research, especially in the numerical modelling of gas-cooled reactor systems, such as pebble bed high temperature gas cooled reactors, for which he has developed coupled multi-physics calculation methods covering reactor physics, thermal-hydraulics and pebble bed mechanics. In addition, he has experience in reactor physics and fuel behavior analyses of light water reactors. Dr. Suikkanen has been involved in several academic as well as more industry-oriented research projects and several expert groups. Most recently he has led a work package on nuclear criticality safety in an EU funded research project in which a new fuel design was developed for older reactor types of Russian design.
