摘要： A hybrid nuclear reactor that is operable to produce a medical isotope includes an ion source operable to produce an ion beam from a gas, a target chamber including a target that interacts with the ion beam to produce neutrons, and an activation cell positioned proximate the target chamber and including a parent material that interacts with the neutrons to produce the medical isotope via a fission reaction. An attenuator is positioned proximate the activation cell and selected to maintain the fission reaction at a subcritical level, a reflector is positioned proximate the target chamber and selected to reflect neutrons toward the activation cell, and a moderator substantially surrounds the activation cell, the attenuator, and the reflector.

摘要： A single-pass heavy-ion fusion system for power production from fusion reactions alone, power production that uses additional energy of fission reactions obtained by driving a sub-critical fission pile with the neutrons from fusion reactions, destroying high-level and/or long-lived radioactive waste by intense bombardment with fusion neutrons, or for the production of neutron beams for various applications includes a new arrangement of current multiplying processes that employs a multiplicity of isotopes to achieve the desired effect of distributing the task of amplifying the current among all the various processes, to relieve stress on any one process, and to increase the design margin for assured ICF (inertial confinement fusion) ignition for applications including but not restricted to the above list. The energy content and power of the ignition-driver pulses are greatly increased, thus increasing intensity of target heating and rendering reliable ignition readily attainable.

摘要： An introduction of nuclear fusion into conventionally fission-based nuclear reactors. Particularly, coolant in the reactor serves as the secondary fuel that absorbs neutrons from the fission core, and releases energy through fusion reactions. Molten Lithium is the preferred coolant in the invention, as it produces Helium gas through the neutron-Lithium fusion without leaving any radioactive or chemical impact to the environment. A Helium pressure controller is also introduced in the system to manage the Helium gas produced by nuclear reactions of the secondary fuel. Lithium Chloride (LiCl) is proposed as the secondary coolant in lieu of the commonly used molten salt in order to achieve higher power production efficiency. A reactor based on the proposed system requires less space than a conventional reactor of the same power. It is a better choice than conventional nuclear reactors when space is a key constraint, for example, on a container ship.

摘要： In the invention, first a relatively large mass is accelerated to a few 10 km/sec and then used to implode and compress a dense magnetized plasma confined inside a small cavity. In the proposed invention the dense plasma shall consist of thermonuclear material, as for example DT, and shall reach upon compression the temperature for thermonuclear ignition. The magnetized plasma is thereby permitted to be preheated by a laser or particle beam or a gas discharge to reduce the required compression to reach thermonuclear ignition. After having reached the ignition temperature the plasma undergoes a thermonuclear burn excursion, greatly increasing its energy content. During this excursion a small window in the wall of the chamber confining the burning plasma breaks open releasing a large amount of the energy within the cavity in the form of black body radiation and shock waves. The energy flux from both the black body radiation and the shock wave is then used to ablatively implode a second stage high density high yield thermonuclear target. The importance of this two stage arrangement is that it permits much higher yields than would be possible with a one stage magnetized target.
摘要翻译： 在本发明中，首先将相对较大的质量加速到几十公里/秒，然后用于压制和压缩限制在小腔内的致密磁化等离子体。 在所提出的发明中，致密等离子体应由热核材料组成，例如DT，并且在压缩时应达到热核燃烧的温度。 从而允许磁化等离子体通过激光或粒子束或气体放电来预热，以减少达到热核燃烧所需的压缩。 达到点火温度后，等离子体发生热核燃烧偏移，大大增加其能量含量。 在这个偏移期间，限制燃烧等离子体的室内壁上的小窗口打开，以黑体辐射和冲击波的形式释放空腔内的大量能量。 然后使用来自黑体辐射和冲击波的能量通量来消融第二级高密度高产率热核靶。 这个两阶段安排的重要性在于，它允许比一级磁化目标更高的产量。

摘要： Enhanced Coulomb repulsion (electron) screening around light element nuclei is achieved by way of utilizing target structures (e.g., nanoparticles) that undergo plasmon oscillation when subjected to electromagnetic (EM) radiation, whereby transient high density electron clouds are produced in localized regions of the target structures during each plasmon oscillation cycle. Each target structure includes an integral body composed of an electrically conductive material that contains light element atoms (e.g., metal hydrides, metal deuterides or metal tritides). The integral body is also configured (i.e., shaped/sized) to undergo plasmon oscillations in response to the applied EM radiation such that the transient high density electron clouds are formed during each plasmon oscillation cycle, whereby brief but significantly elevated charge density variations are generated around light element (e.g., deuterium) atoms located in the localized regions, thereby enhancing Coulomb repulsion screening to enhance nuclear fusion reaction rates. Various target structure compositions and configurations are disclosed.

摘要： A laser inertial-confinement fusion-fission energy power plant is described. The fusion-fission hybrid system uses inertial confinement fusion to produce neutrons from a fusion reaction of deuterium and tritium. The fusion neutrons drive a sub-critical blanket of fissile or fertile fuel. A coolant circulated through the fuel extracts heat from the fuel that is used to generate electricity. The inertial confinement fusion reaction can be implemented using central hot spot or fast ignition fusion, and direct or indirect drive. The fusion neutrons result in ultra-deep burn-up of the fuel in the fission blanket, thus enabling the burning of nuclear waste. Fuels include depleted uranium, natural uranium, enriched uranium, spent nuclear fuel, thorium, and weapons grade plutonium. LIFE engines can meet worldwide electricity needs in a safe and sustainable manner, while drastically shrinking the highly undesirable stockpiles of depleted uranium, spent nuclear fuel and excess weapons materials.
