Fusion core

Fusion core is an ammunition type in Fallout 4 and Fallout 76.

Background
Standardized fusion cores are a high-grade, long-term nuclear battery used for military and commercial applications before the Great War. Used by civilians to power a multitude of devices, from automobiles, to generators, the military instead used them for killing, supplying power armor and some Gatling laser models with energy. Standard core interfaces were developed across the board to allow for power armor frames to use cores salvaged from weapons or generators. The Fusion Core also can be hooked up to certain melee weapons via jumper cables. A specialized variant of the fusion core was developed as well, for use in plasma weapons.

Another benefit is that cores can be set to overload, for use as improvised explosives or to deny a power armor suit to the enemy by destroying it.
