| 20090184298 | PROCESS FOR REPROCESSING A SPENT NUCLEAR FUEL AND OF PREPARING A MIXED URANIUM-PLUTONIUM OXIDE - A process for reprocessing a spent nuclear fuel and for preparing a mixed uranium-plutonium oxide. The process: a) separates the uranium and plutonium from fission products, americium, and curium that are present in an aqueous nitric solution resulting from dissolution of the fuel in nitric acid, the separating including at least one operation of coextracting the uranium and plutonium from the solution by a solvent phase; b) partitions the coextracted uranium and plutonium to a first aqueous phase containing plutonium and uranium, and a second aqueous phase containing uranium but no plutonium; c) purifies the plutonium and uranium that are present in the first aqueous phase; and d) coconverts the plutonium and uranium to a mixed uranium/plutonium oxide. | 07-23-2009 |

| 20110256377 | PHOTOVOLTAIC STRUCTURES PRODUCED WITH SILICON RIBBONS - Photovoltaic elements can be formed by in-motion processing of a silicon ribbon. In some embodiments, only a single surface of a silicon ribbon is processed in-motion. In other embodiments both surfaces of a silicon ribbon is processed in-motion. In-motion processing can include, but is not limited to, formation of patterned or uniform doped regions within or along the silicon ribbon as well as the formation of patterned or uniform dielectric layers and/or electrically conductive elements on the silicon ribbon. After performing in-motion processing, additional processing steps can be performed after the ribbon is cut into portions. Furthermore, post-cut processing can include, but is not limited to, the formation of solar cells, photovoltaic modules, and solar panels. | 10-20-2011 |
