Next-Gen Nuclear Reactors with Molten Lithium as Coolant and Secondary Fuel
20230245791 · 2023-08-03 ·

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.

Provided are apparatuses and methods for providing power to a fission-type nuclear power plant by a reactor with a confining wall at least partially enclosing a confinement region within which charged particles and neutrals can rotate. A plurality of electrodes is adjacent or proximate to the confinement region. A control system having a voltage source applies an electric potential between the plurality of electrodes to generate an electric field within the confinement region to induce rotational movement of the charged particles and the neutrals therein. A reactant is disposed in the confinement region. Repeated collisions between the neutrals and the reactant produce energy and a product having a nuclear mass that is different from a nuclear mass of the nuclei of the neutrals and the reactant. The energy dissipates from the reactor to provide power to the fission-type nuclear power plant.

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.
