Explosive Rekenium

Rekenium is a heavy transuranium isotope of a type theorised by 20th century Earth scientists but never encountered in nature, at least until Kai’s pan-galactic trip.

Existing within the second island of stability, far beyond the reaches of Mendeleev’s revised periodic table, Rekenium is a profoundly radioactive substance that can be used to power a variety of high yield technologies.

When systems require more compact/dense energy sources than are possible with standard fission or fusion ignition, Rekenium is the element to turn to. Superheavy spherical nuclei mean that Rekenium is comparatively stable.

Various terminal research projects have demonstrated that bombarding the element with Hassium-270 will form a short lived but hugely explosive isotope.
