  • ASSYSTEM E.O.S. - ITER - Chemical & Nuclear Plant Engineer

    2010 - 2014 Responsible to execute and provide technical studies to support design orientations and integration of the TCWS (Tokamak Cooling Water System) in the field of radioactive effluent treatment after LOCA (loss-of-coolant accident), nuclear shielding, penetrations, handling and interfaces with the building.
    Development of the concept design of sampling station of the cooling loops (main primaries and secondary). Support to the development of the CWS (Cooling Water System) Laboratories with the definition of apparatus to achieves all required measurements with their integrations in the facility.
    Perform value engineering study on TCWS Heat Exchangers for the usage of shell and plate heat exchangers, including the benchmarking, advantages and drawbacks during lifecycles. The impact and risk analysis in case of integration in the primary loop was proposed and oriented on pressure and nuclear requirements versus standards, quality assurance and in service inspection and maintenance.
    Provide review of CWS P&ID as well as the revision of the SRD (System Requirement Document) to support PCR-273 closure. Impact studies using CATIA and 2D/3D consistency verification of CVCS (Chemistry and Volume Control System).
    Ensure the coordination and study of Project Change Requests. Perform the review of 3D model and propose options for clashes resolution, Implementation of Project Change Requests related to shielding, nuclear handling, sampling and chemistry. Technical solutions from the industry with direct contact with manufacturers for shielding walls and doors.
    Coordination and support for the US-DA delivery follow-up with the definition of priorities for piping analysis and the clarification on IO expectations to fulfil the schedule.
    Definition and implementation of CWS hot laboratory in the Hot Cell Complex.
    Organization of the venue of manufacturers linked to cooling water systems such as pipe supports and heat exchangers.

  • CEA Cadarache - Ingénieur chercheur - Procédés Tritium

    2007 - 2010 It was in the frame of the 6th framework programme EURATOM that a training focused on fusion technology and more especially on the ITER fuel cycle was set up. 5 early stage researchers were selected from EURATOM country members (Germany, Italy, Romania, Hungry and France) and I was the French one. Our group has been called: Fuel Cycle Network for ITER.

    This 3 years contract was divided in 4 sequences:
    • 11 months at CEA Cadarache, France
    • 1 month at JET Culhan research center, Great Britain
    • 10 months at the Tritium Laboratory Karlsruhe, Germany
    • 14 months at CEA Cadarache, France

    My main activities and responsibilities were:

    • Bibliography studies,
    • Feasibility study for B-type waste detritiation unit for ITER Hot Cells,
    • Assessment of tritium outgassing from waste in ITER Hot Cells,
    • Dynamic modelling of B-type waste in ITER Hot Cells,
    • Answer to the calls of tender from EFDA and F4E,
    • Lab scale experiments in waste detritiation including Beryllium, analyses , , 3H.
    • Lab scale experiments for Tritiated water trapping on Molecular Sieve Bed,
    • Tritium transfer modelling for Breeding Blanket modules and the associated loops (Helium, PbLi and water) for ITER and DEMO,
    • Setup of detritiation methods and experimental facility,
    • Writing of technical documents for patents filling,
    • R&D program definition in gas purification linked to Tritium,
    • Preliminary design for an experimental setup using membrane reactor and permeator for Tritium recovery,
    • Contribution for TriPla-CA (Tritium Plant consortium) creation,
    • Management of trainees (end of study interns).

    Contribution of EFDA tasks JW6-FT-1.11, also on JW6-FT-2.29, JW8-FT-2.32, JW9-FT-2.34 and JW10-FT-2.35.
    In parallel I continue to participate to the predictive tools working group in the frame of the TBM-CA and also internally in CEA for the definition of a R&D program on tritium behaviour in breeding blankets.
