Short description of activity:
Learning from operational experience is essential for further safety enhancement in Nuclear Power Plants (NPP). The JRC has initiated a project on NPP operational experience feedback aimed at improving the analysis of events and the use of lessons learned at the EU level. The Institute for Energy and Transport is looking for a dynamic, experienced and motivated senior expert in the field of Operational and Design Safety of Nuclear Power Plants. The job covers safety analyses of NPP and the analysis of events in NPP, including assessment of the safety significance, potential lessons learned and recommendations and will involve collaboration with European Union national nuclear safety regulatory authorities and their technical support organizations. The successful candidate is also expected to contribute to the promotion of the implementation of important lessons learned from operational experience in NPPs.
Qualifications:
The ideal candidate should have a minimum of 10 years of research experience at post-doctoral level or a minimum of 15 years of research experience after the first degree giving access to doctoral studies. Candidates should have preferably: a Master, a PhD, or equivalent experience in mechanical / industrial / electrical / civil / nuclear engineering or nuclear physics. Proven experience in a nuclear Operator, nuclear Regulator or technical Support Organisation, nuclear Designer of power plants, other recognised International Organisation dealing with nuclear operational safety or similar along with knowledge in some of the following fields (for NPP) are desired: safety analysis, operational safety, assessment of nuclear events, inspections, design, maintenance or operation. Knowledge of diverse European designs of nuclear power plants would be an advantage. Capacity to achieve results under tight deadlines, good communication, sense of initiative and team working capabilities in multicultural environment are essential, as is a good computer competence. Fluent level of English is essential.
Indicative duration: 24 months
Preferred starting date: As soon as possible.
