Patent number: 10538448Abstract: Process for confinement of waste containing at least one chemical species to be confined, by in-can vitrification in a hot metal can into which waste and a vitrification additive are added, the waste and the vitrification additive are melted to obtain a glass melt which is then cooled, characterised in that at least one oxidising agent is also added into the metal can and in that the concentration of oxidising agent(s) expressed as oxide(s) in the glass melt is between 0.1 and 20% by mass, preferably 4 and 20% by mass, even more preferably 5 and 15% by mass, and even more preferably 10 and 13% by mass of the glass melt mass.Type: GrantFiled: July 28, 2009Date of Patent: January 21, 2020Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Philippe Gruber, Olivier Pinet, Hélène Rabiller, Roger Boen, Nicolas Bousquet, Jean-Luc Dussossdy, Jacques Lacombe

Patent number: 10262765Abstract: The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste (30) introduced into a reactor (10), by means of a basket (18) in turn passing through an air lock (12). Plasma torches (14) burn all waste (30) contained in the basket (18). The waste is then lowered in a melting bath of a furnace (20) with an inductor (24) including a crucible-forming container (23). A combustion gas treatment train completes the facility. The furnace (20) can be dismantled, after a series of treatments of several baskets (18) of waste (30) for disassembling the crucible-forming container (23) from the furnace (20). Application in treating different radiologically contaminated and/or toxic mixed waste.Type: GrantFiled: August 7, 2014Date of Patent: April 16, 2019Assignee: ORANO CYCLEInventors: Roger Boen, Patrice Charvin, Florent Lemont, Aldo Russello

Patent number: 9719679Abstract: A basket for incinerating waste inside an incinerator for a duration longer than fifteen minutes with no need for waste to be molten earlier, particularly when waste is introduced inside the incinerator. The basket includes mainly of a glass fiber envelope: it is preferably stiffened by a lightweight metal structure located inside or outside the envelope or built into it. A gripping handle is installed on top of the assembly that is stiffened at the top by a metal tube to which a lightweight metal structure is fixed and by a base formed from a drip pan fixed to the base of the lightweight metal structure.Type: GrantFiled: February 13, 2014Date of Patent: August 1, 2017Assignee: AREVA NCInventors: Roger Boen, Patrice Charvin

Patent number: 9662693Abstract: The melting induction furnace comprises, together with a casing (7) to which a lower sole plate (11) is added to form the central part of the structure, a removable inner crucible (1) composed of an internal layer (4) resisting heat and aggressiveness of the molten bath (20), an external layer (6) delimiting the crucible and an insulating intermediate layer (5). The crucible (1) is a disposable crucible and can be stored with its charge in an appropriate container. Heat losses are low, even when the casing (7) is cooled. Stresses due to differential thermal expansions are also very much reduced.Type: GrantFiled: February 17, 2014Date of Patent: May 30, 2017Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, AREVA NCInventors: Roger Boen, Armand Bonnetier
