A supervisor's terminal on the upper floor of the shed contains logs hinting at illegal activity and murder. The terminal allows the security door on the lower level to be unlocked. In 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.
Further proof of their waste dumping can found in the water monitoring terminal near Lake Quannapowitt, just north of the Mass Fusion containment shed. The terminal contains pre-War reports of high radiation in the lake. Pre-War logs at Nahant Oceanological Society show that they were asked to confirm findings from Lake Quannapowitt; the scientist writing the log suspects illegal dumping is at fault for the lake's extreme radiation levels, even when compared to the rise at other sites they had been monitoring.
The interior is a warehouse storing many barrels of radioactive material. There are medium levels of radiation throughout the entire building. It contains glowing radroaches and feral ghouls. The computer to open the security gate is on the top floor, right above it.
There's a hatch that leads into a subterranean chamber near the assembly line; in front of the fusion core, between radioactive barrels. In this subterranean chamber, there's a generator that can be deactivated. Doing this will result in the deactivation of the automated radio alarm broadcast that can be picked up after extending the satellites of radio tower 3SM-U81.
- 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.
Although an automated radio alarm must be deactivated by the generator at the reactor level, there is a ham radio hidden beyond the wall to the west. It can be seen and used only through the console command tcl. The small shed on the east shore of the lake to the north had access to the ham radio.
The Mass Fusion containment shed only appears in Fallout 4.
Behind the scenesEdit
|The following is based on unverified behind the scenes information and has not been confirmed by canon sources.|
It is possible to jump onto the southeast corner of the lower roof, where one will find a synth and a human corpse. This seems to be a reference to the final scene of Blade Runner.

- pc Flipping the circuit breaker in the sublevel 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 sublevel can de-sync with the radio signal if the klaxons are turned off before resetting the radio tower.[verified]
- pc xboxone ps4 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 openactorcontainer 1 as another workaround.[verified]
