History
in Japan 
Connected to the Dismantling of Fukushima Daiichi

  • 1

    2012/2013

    First Opportunities Contributions to "Integrated Dose Reduction Planning" Projects

  • 2

    2014

    Feasibility Study of Fuel Debris Cutting and Dust Collection Technology for Innovative Approach

    (Applicability of laser cutting to Fuel Debris Retrieval collaboration with CEA)

  • 3

    2016

    Project of Development of Fundamental Technologies for Retrieval of Fuel Debris and Internal Structures (Development of laser cutting until 2019 and integration of IRSN on aerosols R&D)

  • 4

    2017-2018

    Advancement of Fundamental Technologies for Retrieval of Fuel Debris and Internal Structures (collect of aerosol)

    Development of small neutron detectors (Feasability for in-situ Fuel Debris Investigations)

  • 5

    2019

    Development for Dust Collection System of Fuel Debris (Collect and Filtration of dust and aerosols)

    Particle Generation Test using Simulated Uranium Containing Debris (characterization of aerosols)

    Conceptual Study on characterization and Storage during 1F large scale FDR (radioactive waste management strategy)

Continued support in R&D for Important Topics (FY 19-21)
