20140140461 | Magnitites Pycnonuclear Reactions within Electrochemical, Radioactive and Electromagnetic Medias - The electrochemically active elements of the transition series include both the third, fourth and fifth d block elements, the lanthanides and the actinides. These transition elements have distinct electrochemistry for driving many chemical reactions, in particular the absorption of large volumes of hydrogen and the formation of various hydrides. In particular, Pd, Th, Ti, Ag, Au and La hydrides exhibit anomalous effects. The chemical reactions for forming, decomposing and rearranging the bonds of metal hydrides involve large energies. Furthermore these metal hydrides and mixtures are here demonstrated to exhibit greater strange cold nuclear reactions both cold fission and cold fusion. This invention provides magnetic, x-ray, laser irradiation, pressure, neutron beam, beta ray, alpha ray, gamma ray and catalytic technology for accommodating the special conditions for more controlled and accelerated cold nuclear reactions within the dense plasma (pycno) provided by the lattice of these metal hydrides. Under these conditions, the cold nuclear reactions are controllably enhanced to rates for practical energy sources but the very nonsynergistic nature of these pycnonuclear phenomena diminishes the possibility of runaway or explosive systems. | 05-22-2014 |

20150085963 | RECOVERING AND RECYCLING URANIUM USED FOR PRODUCTION OF MOLYBDENUM-99 - A processes for recycling uranium that has been used for the production of molybdenum-99 involves irradiating a solution of uranium suitable for forming fission products including molybdenum-99, conditioning the irradiated solution to one suitable for inducing the formation of crystals of uranyl nitrate hydrates, then forming the crystals and a supernatant and then separating the crystals from the supernatant, thus using the crystals as a source of uranium for recycle. Molybdenum-99 is recovered from the supernatant using an adsorbent such as alumina. Another process involves irradiation of a solid target comprising uranium, forming an acidic solution from the irradiated target suitable for inducing the formation of crystals of uranyl nitrate hydrates, then forming the crystals and a supernatant and then separating the crystals from the supernatant, thus using the crystals as a source of uranium for recycle. Molybdenum-99 is recovered from the supernatant using an adsorbent such as alumina. | 03-26-2015 |
20150085964 | RECOVERY OF URANIUM FROM AN IRRADIATED SOLID TARGET AFTER REMOVAL OF MOLYBDENUM-99 PRODUCED FROM THE IRRADIATED TARGET - A process for minimizing waste and maximizing utilization of uranium involves recovering uranium from an irradiated solid target after separating the medical isotope product, molybdenum-99, produced from the irradiated target. The process includes irradiating a solid target comprising uranium to produce fission products comprising molybdenum-99, and thereafter dissolving the target and conditioning the solution to prepare an aqueous nitric acid solution containing irradiated uranium. The acidic solution is then contacted with a solid sorbent whereby molybdenum-99 remains adsorbed to the sorbent for subsequent recovery. The uranium passes through the sorbent. The concentrations of acid and uranium are then adjusted to concentrations suitable for crystallization of uranyl nitrate hydrates. After inducing the crystallization, the uranyl nitrate hydrates are separated from a supernatant. The process results in the purification of uranyl nitrate hydrates from fission products and other contaminants. The uranium is therefore available for reuse, storage, or disposal. | 03-26-2015 |
