One word to describe Otrera: enthusiasm<\/p>\n

What drives you in the project<\/strong>
\nBeing part of a great story, the most promising one in terms of its chances of success, by making my contribution which is recognized, particularly among
\nthose, the vast majority, who have not experienced the sodium-cooled fast reactor sector.<\/p>\n

Your background before Otrera<\/strong>
\nAs a hydraulics and fluid mechanics engineer \u2013 thermal (ENSEEIHT Toulouse), I spent 40 years at Novatome, which became Framatome, in the service of sodium-cooled fast reactors. I performed thermohydraulic calculations before becoming responsible for primary circuit equipment. The major accelerator in my career was taking charge of the leak tests for the 3rd containment barrier (the dome) of SUPERPHENIX. Subsequently at the PHENIX plant for Renovation work, operational support throughout the 6 cycles until production shutdown. Finally, I was Architect of the ASTRID Project, on the Secondary Loops, then on the Primary Circuit. <\/p>\n","protected":false},"excerpt":{"rendered":"
