Reliability improvement of the evacuation route of fuel elements of phenix

Abstract : PHENIX is a French fast breeder nuclear power plant stopped in 2009. The critical path of the plant dismantling is the evacuation of the fuel elements and after the evacuation of the Lateral Neutron Shielding Assemblies (LNSA). This evacuation way, called handling route, needs a reliability of 80% (nowadays estimated at 50%). In 2013 a working group was created to analyze the handling route and specify a roadmap. The working group analyzes the different solutions according to cost, interruption of operations (due to a blocking failure or to the reliability work) for the 47 equipments linked to the handling route. The work has started to specify and manufacture the 16 highest-priority equipements. The manufacturing is starting and the implementation for the 16 equipments will held during 2016 and 2017.
