| 20100294995 | REFLECTOR GRAPHITE CONSISTING OF ISOTROPIC HIGHLY CRYSTALLINE NATURAL GRAPHITE AS THE MAIN COMPONENT AND SILICON OR ZIRCONIUM CARBIDE, AND PRODUCTION THEREOF - Disclosed is reflector graphic which is characterized in that the main component of the graphite is nuclear-purity natural graphite in addition to silicon carbide and/or zirconium carbide, the pressed pieces are shaped by a combined cold-hot pressing process, and the thermal treatment of the pressed pieces is limited to temperatures of less than 2000° C. | 11-25-2010 |
| 20100167905 | MATRIX MATERIAL COMPRISING GRAPHITE AND AN INORGANIC BINDER SUITED FOR FINAL DISPOSAL OF RADIOACTIVE WASTE, A PROCESS FOR PRODUCING THE SAME AND ITS PROCESSING AND USE - A matrix material for safe temporary and/or ultimate disposal of radioactive wastes suitable for the embedment of radioactive wastes, contains graphite and at least inorganic binder which can be glass, aluminosilicate, silicate, borate and lead sulfide. | 07-01-2010 |
| 20100014625 | SPHERICAL FUEL ELEMENT AND PRODUCTION THEREOF FOR GAS-COOLED HIGH TEMPERATURE PEBBLE BED NUCLEAR REACTORS (HTR) - The invention relates to a novel design and production of fuel element pebbles which satisfy the requirements of high temperature pebble bed nuclear reactors of the next generation. The invention uses a shell of the fuel element pebbles that is devoid of fuel and consists of silicon carbide (SiC) and/or zircon carbide (ZrC), in addition to natural graphite and graphitized petroleum coke, said shell having a maximum average nominal thickness of 5 mm and preferably only 3 mm. | 01-21-2010 |
