Is neptunium a synthetic element?
Neptunium, element 93 on the periodic table of elements, was the first transuranium element to be produced synthetically and the first actinide series transuranium element to be discovered. Its discovery came after several false findings of the element, including Enrico Fermi’s attempt to bombard uranium with neutrons.
Is neptunium a fissile?
Neptunium has only been considered, not actually used, as a fissile nuclear fuel. However, neptunium-237 is used to create plutonium-238, which is then used in special energy generators that can power satellites, spacecraft and lighthouses for a long period of time.

Is neptunium a natural element?
Neptunium has been used in neutron detectors. Neptunium occurs naturally in Earth, being present in minute quantities in uranium ores. Today neptunium-237 is extracted in kg quantities from the spent uranium fuel rods of nuclear reactors.
What are uses of neptunium?
While neptunium itself has no commercial uses at present, it is used as a precursor for the formation of plutonium-238, and in radioisotope thermal generators to provide electricity for spacecraft. Neptunium has also been used in detectors of high-energy neutrons.
