Petri Kinnunen

Current position at VTT
Principal Scientist, Research Manager in Nuclear Safety

Research background and current research topics

  • Electrochemistry of materials exposed to various aqueous environments
    - electrochemical behaviour of passive films on Ni- and Fe-based alloys at ambient and elevated temperatures
    - physicochemical modelling of protective oxide films

  • Development of measurement techniques especially for high temperatures
  • High temperature chemistry
  • Activity incorporation in primary circuits of nuclear power plants (NPP)
  • Oxidation of fuel cladding materials in simulated light water reactor (LWR) conditions
  • Corrosion in nuclear waste final repository conditions

Current major research projects at VTT

Currently, my main work topic is the project management of the Jules Horowitz Materials Testing Reactor Finnish in kind project that lasts up to year 2017. (see http://www.cad.cea.fr/rjh/index.html). The other main topic is to manage VTT’s co-funded and self-funded project portfolio in the business area called Nuclear Safety.

FURTHER EDUCATION:

Management training of the Ministry of Employment and the Economy, 2009 - 2010. This course aims at training managers for the ministry and for the organisations working under the governance of the ministry.

Course on Nuclear Safety (YK4) 2006 - 2007.

Industrial Innovation Management (IIM) course at VTT (2004 - 2006). IIM was a training period executed with five industrial companies (Wärtsilä, Vaisala, VTI Technologies, Consolis and M-real) and TEKES to develop novel techniques and strategies for creating new innovations and innovation cultures. IIM included also general management education.

Team leader training at VTT 2008 - 2009

Project management course at VTT in 2001.

International courses:
Instrumental Methods in Electrochemistry, summer course, University of Southampton, UK, 1999.
