Mass Fusion containment shed

The Mass Fusion containment shed is a location in the Commonwealth in 2287. Before the Great War, it was the site of Mass Fusion's illegal nuclear waste disposal operation.

Background
This warehouse for Mass Fusion stored nuclear waste that was waiting to be disposed of at a site near Lake Cochituate. After the war, the waste remains, leaving the area irradiated and containing feral ghouls.

After an employee named Lester died after tripping behind the forklift ending the site's accident free streak of 34 days, corporate required the employees to hang up "remember your hardhat" posters. The supervisor of the location noted that they doubted a hardhat would have prevented the accident. On August 22, a hazardous material inspector stopped in unannounced to check their operation. The supervisor informed Mr. Feld, who told them that if they caught on to the details of their operation, they would need to get rid of him, and "didn't mean ask him to go away" to which the supervisor complied.

Layout
The interior is a warehouse storing many barrels of radioactive material. It contains glowing radroaches and feral ghouls. In the top floor room is the supervisor's terminal, containing personal entries and the lock control for the security gate at the rear of the first floor.

Past the security gate, and next to the conveyor belt, is a floor hatch leading to the subterranean reactor room. The hatch is located behind some barrels next to the conveyor belt, and directly opposite the generator with the fusion core. In the center of the reactor room is the reactor with a circuit breaker switch affixed to the farthest side. The exterior roof can be reached by walking up the tubes along the wall, jumping on the air conditioners and from there to the roof itself.

Notable loot

 * A fusion core on the generator behind the security gate.
 * A Vault-Tec lunchbox is located in the subterranean area on the desk next to a broken terminal.

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

Behind the scenes
On the roof, a dead raider and a synth can be seen in a position similar to the final scene of the movie Blade Runner.

Bugs

 * Flipping the circuit breaker in the sub-level will sometimes fail to disable the automated radio alarm. A workaround is to return to radio tower 3SM-U81 and re-extend the satellites, then return to the containment shed to flip the breaker again. The warning klaxons in the sub-level can de-sync with the radio signal if the klaxons are turned off before resetting the radio tower.
 * Both of the ghouls that are hidden in the radioactive waste in the middle of the warehouse can not be looted directly. A workaround is to order one's companion to search the corpses. On PC, one can open the developer's console, click on the ghoul, and enter the command as another workaround.
