Fusion core (Fallout 76)

The fusion core is an ammunition type in Fallout 76.

Characteristics
Fusion cores are used to power and activate suits of power armor and as ammo in certain weapons, such as the Gatling laser, which utilizes fusion cores as its ammunition; each fully-charged core provides 500 shots.

Weapon/armor using this ammunition

 * Ultracite Gatling laser
 * Gatling laser
 * Power armor chassis

Locations
Fusion cores can be found, created or received as quest rewards. There are currently several ways to obtain them:
 * Scavenge for power armor: On every suit of power armor, one will find a fusion core at quarter charge.
 * Search for fusion generators: Fusion generators encountered while exploring may contain a fusion core; if not, the player character may wait for one to spawn.
 * Craft them: Player characters can craft fusion cores at chemistry stations if they have the right components.
 * Craft Gatling lasers: Each crafted Gatling laser contains a fully charged fusion core.
 * Create them: Providing 100 power to a fusion core processor found at one of the power plants generates 1 fully charged fusion core every 7.5 minutes. The processor holds a maximum of three fusion cores that will need to be collected regularly before it can produce more.
 * Destroy robots: certain models of robot, such as sentry bots, may drop a fusion core on death.
 * Successfully finishing Line in the Sand rewards two fusion cores.


 * Fixed spawns
 * Big Bend Tunnel - In a fusion generator in the storage room with the mole rats.
 * Fort Defiance - In the locked armory on the third floor, on the bottom row of a metal shelf in the southeast corner.
 * Palace of the Winding Path - on metal shelves next to the generator in the basement
 * Wade Airport - in the air traffic control tower, on the desk.

Bugs
Before patch 1.0.4.13, fusion cores would replenish to full charge upon joining another world.
