DEFINITION

Classification: 376/100

NUCLEAR FUSION:

(under the class definition) Subject matter comprising structures and processes in which two reacting nuclei are combined to yield at least one nucleus having a greater mass than either of the reacting nuclei.

(1) Note. Subject matter of this subclass and of the subclasses indented hereunder may include, for example, reactions and methods including neutron generators wherein the neutron is a product of a fusion reaction, e.g., A D-T reaction.

(2) Note. Patents are included in this and indented subclasses even if there is failure of the system to actually obtain fusion if it is clear that the intent or aim of the patent is to obtain it.

(3) Note. Neutrons from an ionized or plasma system or reaction may be appropriately utilized or moderated to bring about or cause a fission-type nuclear reaction.

(4) Note. Energy or heat of a nuclear fission reaction system may be appropriately utilized to bring about ionization to plasma or fusion reaction levels.
