    摘要： Disclosed is a solid lithium-lead blanket for a fusion reactor, where a solid lithium-lead alloy is adopted as a neutron multiplier and a tritium breeder, and is placed in a form of a unitary or binary pebble bed inside a structural skeleton composed of structural materials; and nuclear thermal deposition in the solid lithium-lead alloy generated due to an interaction between the solid lithium-lead alloy and a fusion neutron is moved out by a coolant. A proportion of lead atoms in the solid lithium-lead alloy is low, so that, under normal operations and accident conditions of the blanket, the solid lithium-lead alloy always remains in a solid state without melting, and tritium can be brought out of the reactor by purge gas flowing through the pebble bed to allow tritium self-sufficiency. The blanket of the present disclosure does not require beryllium to meet the requirements of tritium breeding.

    摘要： All magnetic nuclear fusion devices face common technical challenges related to power and particle control arising from the close proximity of a thermonuclear plasma to the plasma-facing component. The plasma-facing component is subjected to high incident power density and erosion processes, and must facilitate the efficient remove of the fusion-ash. In the past, limiters and divertors have been used in magnetic fusion devices for this purpose. These are discussed and extended to a new concept, the “stochastic mantle”, which utilizes a stochastic magnetic field layer to disperse power on the plasma-facing component to the maximum extent possible. Further, if operated at sufficient plasma collisionality, it reduces the energy of particles incident on the plasma-facing component, globally reducing erosion by physical sputtering, while producing high gas pressures for fusion-ash removal through pumping ducts. The approach is particular suited for stellarators, but others devices may be considered.

    摘要： Methods and systems are provided for increasing energy output from Z-pinch and other plasma confinement systems. In one example, a system may include memory storing instructions that, if executed by one or more processors, cause the system to adjust one or more parameters to generate a magnetic field which is sufficiently strong to axially compress a fuel gas to induce thermonuclear fusion and increase a fusion energy gain factor greater than a fusion energy gain factor limit attainable by the thermonuclear fusion. In certain examples, adjusting the one or more parameters may include adjusting a duty cycle of a discharge current applied to the fuel gas based, at least in part, on an amount of thermal collisions between fusion byproducts and the fuel gas. In certain examples, by adjusting the duty cycle, the magnetic field may be adjusted to induce or increase the thermal collisions.

    摘要： A method for generating heat reactions between hydrogen isotopes and a metal catalyst includes placing at least one fuel source within a reactor. The reactor includes an anode and a cathode, wherein the cathode is a metallic vessel, wherein the at least one fuel source comprises a metal substrate thermally sprayed with a metal catalyst, and wherein the at least one fuel source is in thermal and electrical contact with the reactor. The method includes sealing the reactor to produce a vacuum within the reactor. The method includes adding hydrogen to the reactor and adding deuterium to the reactor. The method includes supplying a current to the reactor from a DC power supply.
