  • Unsaturated polyester-based material for neutron-shielding and for maintaining sub-criticality
    Patent number: 7524438
    Abstract: The invention concerns a neutron shielding material for maintaining sub-criticality based on unsaturated polymer: Said material comprises an unsaturated polyester resin, at least an inorganic boron compound, and at least a hydrogenated inorganic compound, in amounts such that the boron concentration is 4.1021 to 25.1021 atoms per cm3 and the hydrogen concentration is 3.1022 to 5.5.1022 atoms per cm3.
    Type: Grant
    Filed: September 27, 2002
    Date of Patent: April 28, 2009
    Assignee: Cogema Logistics
    Inventors: Pierre Malalel, Martine Valiere
  • Material for neutron shielding and for maintaining sub-critically, process for its preparation and its applications
    Patent number: 7399431
    Abstract: The invention relates to a material for neutron shielding and for maintaining sub-criticality, and a process for preparation of this material and applications of the said material. The material comprises a matrix based on a vinylester resin, at least one polyamide and an inorganic filler capable of slowing and absorbing neutrons. Applications: manufacturing of neutron shields in packagings for transport, interim storage and/or ultimate storage of radioactive materials, particularly packagings for new nuclear fuels.
