One trap is in the radioactive zone. Theres a button on the wall by the door that raises the radioactive waste up to a point. Another is in the round office area (trap zone) before you head into the office you will find a door with a scanner looking button, follow the hallway and you'll find the button that closes off the office and drop the person in there into the fusion reactor. Thats all I know of besides the traitor tester. For the traitor tester, you have to find a container with an orb in it. and place that into the side machine.

Thanks!

there are more i know that

There is a piece of floor of the core control level that can be removed to drop people into the waste as well, no idea how to activate it but you can use context menu to remove that chunk of floor, you can noclip into the ground to see it.
