Martin Zimmermann (Chairman)

Martin Zimmermann has been a member of the ENSI Board since 1 April 2017.

Since joining PSI (then known as EIR) in 1980, he has gained over 30 years’ experience in the field of deterministic safety analysis of light water reactors. Over the course of his professional career at PSI, he went on to lead the research groups for «system analysis», «core behaviour» and «fuel behaviour». Having been involved in the STARS project from its conception at the end of the 1980s, he then led the project from 1994 to 2008. STARS aims to establish a comprehensive methodology for the deterministic safety analysis of Swiss nuclear power stations and, over the years, has developed into a key research project for ENSI. Important elements included the introduction and validation of modern computer codes.

Participation in international research programmes such as NURESIM (EU), NURISP (EU), NURESAFE (EU) and Halden (OECD) served to boost visibility, including on the international stage, and to expand scientific cooperation, for example in the form of work carried out for the Finnish supervisory authority STUK regarding the safety analysis of the EPR.

From 2008 to 2012, he was appointed to manage the Laboratory for Reactor Physics and Systems Behaviour on an interim basis. One focus of this work was the development of the safety case for carrying out reactor physics experiments in the retrofitted PROTEUS zero-power reactor.

After a brief period as Deputy Head of Division, he was appointed ad-interim Head of the Nuclear Energy and Safety (NES) Division in August 2013. He developed a new divisional strategy that addressed emerging challenges in relation to energy policy (Energy Strategy 2050). After retiring at the end of August 2016, he worked as a part-time scientific adviser at PSI until his appointment to the ENSI Board.

As well as being a member of expert groups at the national level, he acted as PSI’s representative on the NEA CSNI from 2003 to 2016. As chairman of the CSNI Task Force «Safety Margin Assessment and Application (SM2A)», he dealt extensively from 2007 to 2009 with the quantification of (eroding) safety margins, which is based on the integration of deterministic and probabilistic methods.

He has participated in several IAEA missions, primarily in the capacity of a lecturer as part of further education programmes. As part of the master’s programme in «Nuclear Engineering» organised jointly by ETHZ, EPFL and PSI, he was awarded a lectureship on the topic of fuel behaviour from 2008 to 2013.

He is a member of the «Comité de Visite» of IRSN and also a member of the International Advisory Council of Harbin Engineering University, College of Nuclear Science and Engineering, China.

Martin A. Zimmermann received his Diploma in Experimental Physics from ETH Zurich.
