Nuclear Physicist

Nuclear Physicist is a perk in Fallout 4.

Abilities

 * Rank 3 states that a fusion core can be used as grenades though in truth they act more like time-based mines. To use this feature, the player has to have no explosives selected in their inventory. To use the ability the player has to use the 'throw explosives/mine ability'. Once used the Fusion core will be ejected from behind the player. It will begin to beep and after approximately four seconds it will detonate. It will let off a nuclear explosion similar to a destroyed vehicle or a Mini nuke with the damage being similar.
 * This ability can be used accidentally easily as you only have to press the button and not hold it down. On a PC using a keyboard, the ability can also be used incidentally when using Alt-tab as Alt is the default key used to activate the ability. When returning to the game and resuming, often there will be a Fusion core mine. It is recommended you save prior to minimizing Fallout 4.
 * The ability can be useful when used while fleeing enemies, particularly since the core is ejected behind you.
 * This ability can also be used whilst use a jet pack upgrade. This can be both an entertaining and effective tactic for dispatching large groups of enemies.
 * The ability has no cool down. As long as you have fusion cores, you can eject a fusion core 2-4 times per second.
