You'll most likely get this from simply playing. Just start up the reactor without it failing.

The opposite of Reactor Startup Success. Start up the reactor and have the (slightly rare chance) of it failing.

Heat the core until around 5,000 kelvin, the meltdown itself is from the core integrity getting below 10% or so.

Exact opposite of Reactor Meltdown. Simply freeze the core.

The reactor can be shutdown after 5 minutes of the core being turned on and integrity is at 100%. It costs 30 robux to be able to hit the button.

Heat the core to around 5,000 kelvin, and then start cooling it. I recommend standing nearby the shutdown button in the Cafeteria, walking over to the other farthest one, and then resetting to get closer to the last few. Once you hit all the shutdown buttons, go to the main reactor control and hit the reactor shutdown button and hope it succeeds.

Probably the hardest badge in this game, the exact same steps as Reactor Shutdown Success, however you need to get the (from what I can tell) rare chance of it failing.

Obtained when a breaker fails randomly. Pure chance.

Obtained for fixing a breaker within 5 seconds of it breaking.

Obtained by keeping the core in Critical or Subzero state (hot or cold respectively) for 6 minutes.

Keep the core alive for 15 minutes.

Obtained after making it to the bunker during a meltdown.

Obtained from getting on the boat after you get teleported from when the bunker closes with you in it.

To do this, you must reach a combo of x1000. From my experience, this is best done with a friend just spamming the power laser control or cooling fans control.
