I had a few people unfamiliar with how supermatter in new Bay works, so here's a quick guide on how to get it running without exploding everything.
First off, the supermatter requires two things: coolant, and power. Coolant is injected using chilled nitrogen, the supermatter crystal constantly expels waste gasses that get hotter and hotter. If those gasses aren't vented, it will quickly go critical and explode, giving everyone on the z-level high doses of radiation and hallucination. So the waste must also be filtered out. Second, the supermatter won't start generating power unless it gets power to begin with, which is why there's an emitter in there.
NEVER enter the reactor chamber without a full radiation suit and meson goggles. There's a bunch of suits in there, and goggles, so use them. Just looking at the crystal without mesons on will give you hallucinations.
If the supermatter starts going critical, there will be obvious warning messages. It will also start to glow bright red. If this is the case, you'll need to eject the core from the ship, you can do so via a button near the consoles. It will launch the core into space.
Setup
When the round starts, the supermatter will be inert. It will just sit there, not gaining power. So it's safe to do a few things before actually firing it up.
First off, fill the orange plasma tanks with the plasma canisters located at the south end of the reactor room (don't spray gas everywhere!). Put 8 of those tanks in the collectors, labeled '2', and turn them on by clicking on them. They draw power from radiation, which the crystal emits once it's powered, into the yellow power cables.
Second, turn on the coolers (labeled 1). They should be set to 0 degrees, the coldest you can get. They will immediately begin cooling off the nitrogen gas that's already in the blue pipes. If you need more nitrogen you can turn on the purple intake pipe, but you'll also need to go up to atmospherics and turn on the other end of it. This will siphon nitrogen directly out of the main tank. You shouldn't need to do this at all, there's plenty of nitrogen canisters you can just replace, but it's there if you need it.
Third, the main coolant pump is labeled '3'. Turn that on and make sure it's at max pressure. This will begin feeding icey-cold nitrogen coolant into the core.
Next, turn on the gas filters. These are labeled '4'. They should already be set to filter out nitrogen, make sure they stay that way and are filtering at maximum pressure. This will suck out the waste gasses, and pump the now-hot nitrogen back into the coolant system if you turn on the pump labeled '6'. The other waste gas (oxygen and plasma) will go into the grey pipes down into the filter area. You shouldn't need to do anything down there unless you want to collect some of it.
If there's a LOT of nitrogen it might not get filtered out properly. Turn on the pump labeled '7' and it will route the waste nitrogen back up to atmospherics and dump it in the waste tanks.
Finally, when everything's all set up, open the central blast door and turn on the emitter, labeled '5'. Firing it around 10-12 times should be more than enough. Any more than that and the coolant will not be able to stop the heat from overloading the crystal, and thus blowing everything to kingdom come. So once it's shot that many times, shut it off, close the door, and never touch it again. You could unweld and drag it away if you're afraid someone might touch it.
In the top left of engineering are the SMES, the station's battery supply. Use the yellow power console in front of the windows to check how much power the supermatter is generating, and then set the SMES input so it about matches that amount total. Ie. if it's generating 450,000 watts, set each one to intake 150,000 and they'll charge at the same speed. This is MORE than enough to power the whole ship for a long time. You can also turn on the core SMES as a spare battery, it'll directly charge from the radiation collectors (it's also used to power the emitter if the main battery runs out).
There are two spare SMES's located in the middle of the ship, near the ladder area.
When the supermatter is stable and the SMES cells are charging, go over and turn these on. If the supermatter explodes at some point you'll be quite glad you had some spare batteries with power in them.
