  • Nuclear fuel reprocessing using hydrophilic substituted hydroxylamines
    Patent number: 6444182
    Abstract: The spent nuclear fuel reprocessing method includes contacting an organic phase containing Np(VI) with a hydrophilic substituted hydroxylamine in which at least one N—H hydrogen of the hydroxylamine is replaced by an organic substituent, there being at least one such organic substituent having one or more hydroxyl groups. Np(VI) is reduced to Np(V), which is then backwashed into an aqueous phase.
    Type: Grant
    Filed: July 11, 2000
    Date of Patent: September 3, 2002
    Assignee: British Nuclear Fuels plc
    Inventors: Sergey Mikhailovich Baranov, Valentin Sergeevich Koltunov, Robin John Taylor, Iain May
  • Method for reprocessing nuclear fuel by employing oximes
    Patent number: 6413482
    Abstract: A spent nuclear fuel reprocessing method includes contacting an organic phase containing NP(VI) with an oxime of the formula R2C═NOH, where each R is independently H or an organic substituent. Np(VI) is reduced to Np(V) which is then backwashed into an aqueous phase.
    Type: Grant

    Date of Patent: July 2, 2002
    Assignee: British Nuclear Fuels plc
    Inventors: Sergey Mikhailovich Baranov, Valentin Sergeevich Koltunov, Eduard Andreevich Mezhov, Robin John Taylor, Iain May, Victor Georgievich Pastuschak
  • Nuclear fuel reprocessing
    Patent number: 6093375
    Abstract: A spent fuel reprocessing method includes at least the formation of an aqueous solution and at least one solvent extraction step. Formohydroxarmic acid is used to reduce any Np(VI) to Np(V) and/or to form a complex with Np(IV). As a result, substantially all the neptunium present is retained in the aqueous phase during solvent extraction.
