Eija Karita Puska

Current position at VTT

Chief Research Scientist, Research Coordinator (Nuclear Energy), Team Leader (Nuclear power plant modelling)

Research background and current research topics

My professional career at VTT started with Master’s Thesis on application of nuclear fuel thermomechanical behaviour models. During the first eight years of my career I worked with analysis of nuclear fuel behaviour and completed in 1984 also my Licentiate thesis in the area on stress corrosion cracking failure vulnerability in light water reactor fuel rods.

In 1986 I was enlisted into the just starting development project of APROS simulation environment. Since then APROS, developed and owned together by VTT and Fortum, has become a success story. My tasks with APROS have involved development of the nuclear reactor core models and applications of the code in nuclear area. I have been project manager in two full-scope simulator nuclear simulator software deliveries and in several safety analyses applications. I have also worked at six short IAEA expert missions dealing with APROS.  Currently my main tasks on APROS are on the managerial side and in tutoring student work.

Since 1999 I have been involved in the administration of the Finnish national research programmes on reactor safety. First in 1999-2002 as research co-ordinator of the Finnus programme, then as director of the SAFIR programme 2003-2006 and since 2007 as director of the SAFIR2010 programme.

Current major research projects at VTT
