A neutronic reactor is a type of nuclear reactor that uses a high-energy neutron chain reaction to generate power through the fission of atomic nuclei. This type of reactor is designed to maximize neutron interactions for efficient energy production.
The person who invented the Breeder Reactor in the 1950s was by a team led by Walter Zinn
There have been many European inventions throughout history. Some of these inventions were adhesive postage stamps, golf, fax machines, economics, whisky, the mechanical anemometer, electroplating, the neutronic reactor, and liposuction.

As asked this question has no answer, as there are no propellants in nuclear reactors.
The nuclear reactor was invented in 1933 by Leo Szilard, in London, but he did not try to build one. The first functioning nuclear reactor, CP-1, was designed and built in 1942 by Enrico Fermi, in Chicago, IL.

A neutron don't contain electrons; the mass of an electron is approx. 1/1850 of the neutronic mass.
