Mass Fusion containment shed

The Mass Fusion containment shed is a location in the Commonwealth in Fallout 4.

History
A lot of the backstory is implied at this site, there is a supervisor's terminal on the upper floor of the shed which has logs hinting at illegal activity and murder. The terminal allows you to unlock the security door on the lower level and if you go into the caged area with the stacked barrels, there is a hole in the shed with an open water pipe, implying they were dumping waste into it.

Assuming they didn't murder the person hinted at in the supervisor's terminal logs, they just dumped him in the open water pipe and he mutated into a ghoul, as when you approach, a legendary ghoul crawls out of it.

Layout
A warehouse storing many barrels of radioactive material. There are medium levels of radiation throughout the entire inside of the building. It contains glowing radroaches and feral ghouls, including a legendary one (which can be looted). The computer to open the security gate is on the top floor, right above it.

Inside the gated area is a hidden hatch to the basement. The basement contains a switch to turn off the radio signal.

Notable loot

 * A fusion core on the generator behind the security gate.
 * A box of leveled weapons and ammo behind the barrels near the generator.

Appearances
The Mass Fusion containment shed only appears in Fallout 4.
