Provided are a method and apparatus for low energy nuclear reactions in hydrogen-loaded metals. A nickel cathode is disposed inside a pressure vessel loaded with heavy water. The vessel is heated to a temperature at which nickel oxide is reduced in the presence of hydrogen. The cathode is electrified, thereby producing hydrogen at the cathode, which removes any oxide layer on the nickel. The nickel can therefore more easily be loaded with hydrogen. The nickel cathode preferably has embedded particles of neutron-absorbing and/or hydrogen absorbing materials, such as boron-10, lithium-containing compounds, palladium, niobium, vanadium, or other hydrogen storage intermetallic compounds, alloys, or amorphous alloys.

The invention designs a comprehensive inertial confinement post-controlled nuclear fusion power station, aiming at overcoming the defects of the conventional controlled nuclear fusion technology and utilizing nuclear fusion energy, and providing new concepts such as comprehensive inertial confinement, post-controlled nuclear fusion and the like, new technical routes and new structures thereof. Various heat-absorbing buffer blocking layers made of low-melting-point metal are loaded around various nuclear fusion devices to form a fuel nuclear fusion device (2) or a fuel explosive. The power station is connected in a nuclear long cylinder (1) serving as a novel pressure vessel, so that the entire fuel explosive is kept under inertial confinement in a static state to realize two nuclear fusion reactions, namely one-time combustion and explosion. The low-melting-point metal has the effects of absorbing heat, reducing pressure and vibration and forcing axial bursting and is finally melted into metal liquid to serve as a heat-conducting medium to be led out of the cylinder for power generation and heat utilization. The specific structure of the novel nuclear fusion power station is designed; and engineering, experimental and calculating data fully prove that the power station can be completely realized by adopting the current engineering technology.

FIELD: nuclear physics and nuclear engineering; developing basic concepts for harnessing nuclear fusion energy.SUBSTANCE: proposed method intended for harnessing nuclear fusion energy to develop economically efficient and environmentally friendly energy sources includes continuous supply of electrolyte to and its discharge from electrochemical cell with transition metal electrodes, their polarization in the course of electrolysis of heavy water and/or heavy water doped with deuterated hydroxide of alkali metals while passing pulsating current through electrolyte. This current is produced as soon as low dc ripple voltage noticeably exceeding decomposition potential is applied across electrodes. In the process active centers are periodically formed for conducting nuclear fusion reactions at electrode-liquid boundary. They are formed by periodically reversing polarity of low dc ripple voltage and/or films from dendrites of transition metals having fractal structure on electrode surface. These films are formed by continuously dissolving salts or oxides of transition metals in heavy water followed by their electric deposition on electrodes. For running nuclear fusion reactions collapsing microbubbles with light-element atom pairs are generated near and/or on developed electrode surface with active centers. To this end high ripple voltage of 500 to 20 000 V in amplitude , 0.1 to 100 μs in length, and adjustable on-off time ratio of 5 to 50 is periodically applied across anodic and cathodic electrodes.EFFECT: enhanced speed and number of sporadic and uncontrolled nuclear fusion reactionsconducted by proposed method.8 cl, 2 dwg, 1 ex

Hydrogen and its isotopes (deuterium and tritium) are easily absorbed intometals like palladium or titanium, forming an interstitial solid solution.In the lowest-lying states, even at high densities, the collisionprobability between two of the absorbed hydrogen isotopes is a vanishing orabsolutely negligible quantity. Nevertheless there are relatively low-lyingexcited states ( quantum collision states) for which the overlap probability is non-negligible. Typically, the quantum collision levels are separated from the ground state by energies in the ultraviolet - low X-ray range. Therefore they cannot be accessed by thermal excitations but may beresonantly excited by electromagnetic radiation. This leads to the proposal of a new process for energy production by nuclear fusion reactions: (1) The metal lattice is charged with the hydrogen isotope up to a level inwhich a large of number of the interstitial cages have at least two isotopeunits. (2) The quantum collision states are excited by resonant electromagneticradiation.

FIELD: controlled fusion; extracting fusion energy, generating three-dimensional neutron sources (for instance to recover nuclear wastes). SUBSTANCE: method involves irradiation of heavy particles of fuel pellets injected in reactor chamber wherein high pressure of working gas not lower than atmospheric pressure is maintained using laser pulses or beams for the purpose. In the process problems of production of hot plasma, maintenance of inertialess current, and monitoring of plasma-magnetic configuration are solved. Circuit arrangement of magnetic fusion reactor of proposed type enables directly placing the installation in steady state running dispensing with rather sophisticated standard scheme of organizing hot plasma (gas breakdown at low working gas pressure, preheating of plasma with ohmic current, and the like). Proposed reactor enables combining advantages of magnetic heat insulation and near-wall plasma confinement implemented by building up so-called high- pressure gas cushion at plasma boundary. Proposed method may be found useful for installations with magnetic field configuration of tokamak, stellarator, or adiabatic trap type. Near-wall plasma confinement used in tokamaks makes it possible to avoid dangerous instability of discharge failure. As rather high pressure (and density) of plasma can be maintained in proposed reactor (compared with traditional magnetic confinement of plasma), this reactor can be used for conducting fusion reactions at low section of reactions (for instance in case of D+He3 nuclei fusion reaction). EFFECT: enlarged functional capabilities. 1 cl, 1 dwg

A particle accelerator (12) generates an input particle beam having an initial energy level above a threshold for generating secondary nuclear particles. A thin target (14) is rotated in the path of the input beam for undergoing nuclear reactions to generate the secondary particles and correspondingly decrease energy of the input beam to about the threshold. The target (14) produces low energy secondary particles and is effectively cooled by radiation and conduction. A neutron scatterer (44) and a neutron filter (42) are also used for preferentially degrading the secondary particles into a lower energy range if desired. -GOVT PAR This invention was made with Government support under contract number DE-AC02-76CH00016, awarded by the U.S. Department of Energy.

| 08147681 | Sandia Corporation | Horn Kevin M. |
Ion-induced Nuclear Radiotherapy (INRT) is a technique for conducting radiosurgery and radiotherapy with a very high degree of control over the spatial extent of the irradiated volume and the delivered dose. Based upon the concept that low energy, ion induced atomic and nuclear reactions can be used to produce highly energetic reaction products at the site of a tumor, the INRT technique is implemented through the use of a conduit-needle or tube which conducts a low energy ion beam to a position above or within the intended treatment area. At the end of the conduit-needle or tube is a specially fabricated target which, only when struck by the ion beam, acts as a source of energetic radiation products. The inherent limitations in the energy, and therefore range, of the resulting reaction products limits the spatial extent of irradiation to a pre-defined volume about the point of reaction. Furthermore, since no damage is done to tissue outside this irradiated volume, the delivered dose may be made arbitrarily large. INRT may be used both as a point-source of radiation at the site of a small tumor, or as a topical bath of radiation to broad areas of diseased tissue. -GOVT PAC GOVERNMENT RIGHTS PAR The Government has rights to this invention pursuant to Contract No. DE-AC04-76DP00789 awarded by the U.S. Department of Energy.

Method for recovery of actinides from nuclear waste material containing sintered and other oxides thereof using O.sub.2 F.sub.2 to generate the hexafluorides of the actinides present therein. The fluorinating agent, O.sub.2 F.sub.2, has been observed to perform the above-described tasks at sufficiently low temperatures that there is virtually no damage to the containment vessels. Moreover, the resulting actinide hexafluorides are not destroyed by high temperature reactions with the walls of the reaction vessel. Dioxygen difluoride is readily prepared, stored and transferred to the place of reaction.

Charged-particles in the 45-15 MeV energy range incident upon isotopically enriched xenon-124 gas in a gas-target assembly cause nuclear reactions which yield radioactive xenon-123. The xenon-123, decaying either in the target assembly or in a decay vessel removed from the target assembly, yields iodine-123 with very low levels of radioactive contaminants.

37. | US | 4193855 - Isotope separation by multiphoton dissociation of methylamine with an infrared laser | 18.03.1980 |
| 05892228 | Allied Chemical Corporation | Tuccio Sam A. |
Methylamine (CH.sub.3 NH.sub.2) is dissociated into CH.sub.3 .multidot. and NH.sub.2 .multidot. radicals when irradiated with the output from an infrared laser. Ammonia (NH.sub.3) is then formed inherently through radical and molecular collisions. By tuning the laser to the appropriate frequency, the dissociation process is isotopically selective. As a consequence, ammonia, or other nitrogen containing compounds, are obtained which are selectively enriched in .sup.14 N or .sup.15 N. Carbon isotopes may be separated with essentially the same technique. .sup. PAC BACKGROUND OF THE INVENTION PAR 1. Field of the Invention PAR The present invention relates to enrichment and separation of isotopes, in particular .sup.14 N and .sup.15 N, and .sup.12 C and .sup.13 C by multiphoton dissociation of methylamine. PAR 2. Description of the Prior Art PAR The projected use of .sup.15 N in the nuclear industry is expected to reach 500,000 kg/year. Major use is in fuel pellets and cladding in uranium and plutonium nuclear reactors. Also, .sup.15 N and .sup.13 C are presently used as tracers in the fields of medicine and research. Low cost schemes for separating these isotopes are accordingly required. PAR Ambartsumyan et al. in Vol. 17, Journal of Experimental and Theoretical Physics Letters, pp. 63-65 (1973) disclose isotope separation of .sup.14 N and .sup.15 N by a two-step photodissociation of .sup.14 NH.sub.3 and .sup.15 NH.sub.3, in which monochromatic radiation of a frequency .nu..sub.1 selectively excites a vibrational transition of molecules of only one isotopic composition. The molecules are simultaneously illuminated with light of frequency .nu..sub.2, the quantum energy of which is sufficient for photodissociation of only the vibrationally excited molecules. However, this is a costly process and provides a possibility of isotopic scrambling due to four different intermediate chemical reactions. PAR Robinson et al. in U.S. Pat. No. 4,049,515, issued Sept. 20, 1977, disclose laser isotope separation schemes by multiple photon absorption. Briefly, the schemes involve irradiating a molecular species having at least two isotopes of an element with infrared laser light of a frequency which selectively excites to a vibrational level only those molecules of the molecular species containing a particular isotope. Use of multiple photon absorption produces a sufficiently energetic vibrational state such that the molecules containing the particular isotope undergo a chemical reaction, such as dissociation or reaction with a second molecular species. The patent discloses two examples for which laser induced enrichment was obtained; namely the enrichment of .sup.34 S in natural SF.sub.6 and .sup.11 B in natural BCl.sub.3. However, there is no teaching therein of a method for selecting a candidate molecular species from the essentially infinite number of species which exist for any given element for which the process of Robinson et al. is applicable. When a molecule is subjected to infrared radiation in the manner taught by Robinson et al., the isotopic shift is generally masked by other vibrational modes or, if unmasked, has a magnitude lower than that required for isotope separation. In addition, it has not been possible to precisely predict the manner in which a molecule will dissociate or react with other species when subjected to high intensity infrared radiation. Hence, no general method can be given for devising a laser-chemical reaction system which will effect removal of the desired isotopic species. As a result, it has heretofore not been possible to predict which molecules lend themselves to laser isotope separation by multiple photon absorption. PAR Although present usage of .sup.15 N is small, projected use in core elements of liquid-metal fast breeder reactors is considerable, as mentioned above. Current separation of .sup.15 N is accomplished by NO distillation, or by chemical exchange between NO and HNO.sub.3. The latter process has an enrichment factor of about 1.055. The only proposed separation of nitrogen isotopes with a laser discussed above (Ambartsumyan et al.) suggests an isotopic enrichment factor of about 4. However, the considerable potential for isotopic scrambling renders the proposed process unsuitable on a commercial scale. PAR Carbon isotopes are presently separated by lowtemperature distillation of carbon monoxide and by gas phase thermal diffusion of methane. The carbon monoxide process for separating .sup.13 C is based on a vapor pressure differential that yields an enrichment factor of about 1.011. PAC SUMMARY OF THE INVENTION PAR The present invention provides a process for obtaining nitrogen containing compounds which are enriched in a particular isotope of nitrogen. The process comprises exposing gaseous methylamine containing two or more isotopes of nitrogen to substantially monochromatic infrared laser radiation. The frequency of the infrared radiation is coincident with a vibration absorption band of the methylamine, producing dissociation of the methylamine into CH.sub.3 .multidot. and NH.sub.2 .multidot. radicals. Through molecular and radical collisions, the NH.sub.2 .multidot. radicals abstract a hydrogen atom, forming ammonia. The addition of other gaseous materials, such as oxygen, can be added to the methylamine to scavenge the NH.sub.2 .multidot. radicals to form other nitrogen containing compounds. The process is accomplished isotopically selectively by employing a vibrational band which exhibits an isotope shift. Specifically, .sup.15 NH.sub.3 was obtained with an enrichment factor of 1.65. PAR The process provided herein may be directly applied to the enrichment of carbon isotopes by slightly modifying the wavelength of the laser radiation employed.

38. | US | 4140601 - Multi-step chemical and radiation process | 20.02.1979 |
| 05667610 | Texas Gas Transmission Corporation | Gomberg Henry J. |
A process which utilizes radiation energy, preferably that obtained from a fusion reaction and which includes selecting starting chemical materials having at least two molecules such as calcium bromide and water which contain as a part thereof a desired product H.sub.2, a by-product O.sub.2 and which chemically form an active material HBr that may be dissociated by radiation. A two step process permits the radiolytically dissociated Br to react with residual molecules to form and recycle the starting material CaBr.sub.2. A combination of thermochemical and radiolytic reactions such as available in nuclear reactions therefore produces a greater yield of a desired end product such as hydrogen, also producing a by-product such as oxygen from a low cost expendable source material such as water, and reforms the starting material. Also the process provides for convenient separation of the desired end products.
