Hello everyone, I am Sugardust. Today I will be using my very vague and generic knowledge of the R-UST to hopefully provide a detailed step-by-step guide on how to set it up and generate some electricity for the Torch. Enjoy! Disclaimer - I will be only going over a deuterium-hydrogen setup in this guide. I am not knowledgeable enough to provide extensive knowledge on other combinations, but deuterium-hydrogen is by far the easiest to set up and get a quick reaction going. You will only need to bring along a toolbelt with some basic tools, and it's nice to bring along a welding mask/goggles if you don't want to go blind. Grab your tools and head over to the R-UST inner chamber. Once you're through the airlock it's important to take note of some of the machinery in this room. Directly in front of you is the SMES that powers the machine in the middle of the room called a gyrotron. The gyrotron is basically a laser that keeps the core of the reactor stable. This should ALWAYS be receiving power. On the north end of the room is a rack of deuterium ingots, as well as a radioactive crate containing tritium ingots. Both of these ingot types can be processed in the machine next to them into fuel rods. The MRSPACMAN generator, also nearby, is retrofitted to use tritium as a fuel source as well. To the north and south of the reactor chamber are 6 machines called fuel injectors. These are where you insert your fuel rods. Now that we know what's in the room and what most of it does, we can move on to how to repair the room. Step 1: Repairing the Reactor When you first arrive in the chamber, you will notice a couple wires are missing, pretty much everything isn't even secured to the floor, and overall the room is just in a bad state. Before we can turn on our reactor, we first have to get the room in a functioning state. So, grab your tools, and do the following: Wrench each fuel injectors to the floor. Wrench the MRSPACMAN generator to the floor. Wrench the gyrotron to the floor, and then repair it with the blowtorch. Reconnect the missing wires leading to the reactor wall and to the MRSPACMAN generator. Step 2: Reactor Preparation We've now repaired the missing and unsecured parts in the room. It's now time to prep the reactor for use. Grab some deuterium sheets and process 6 deuterium fuel rods in the processor. Insert them into the fuel injectors, one each. Insert some tritium sheets into the MRSPACMAN generator. Drag a hydrogen canister onto the connector port of the reactor casing. Make sure to turn the gas pump on, but do not toy with any of the settings. Secure the canister onto the port with a wrench. Bump up the MRSPACMAN generator to 3/10 or 4/10 and turn it on. Be sure to check it every so often as it will overheat and may explode. Step 3: Turning On The Reactor We've now successfully both repaired and fueled the reactor, and it is now ready to start producing electricity for the ship. Now, step back inside the control room and have a seat in front of the main 3 consoles. The console to your left is the gyrotron control, the center console is the main reactor control, and the console to your right is the fuel injection control. Everything should be prepared and ready for a safe startup so let's begin. Open the gyrotron console. Lower the delay to '2' and up the power to '50'. This is the min/max gyrotron setting, and provides the most stability with the minimum fire delay and the maximum fire power. Turn on the gyrotron. Note: You can lower delay to 1, but I have never had a reason to, and 2 works good enough/the same. Turn on all 6 fuel injectors. They will begin injecting deuterium into the reactor. On the center console, turn on the field generator. Immediately bump up the 'Field Strength' value to 20.1 tesla. Anything over 20 will work, but do not go past 50. Great job. The reactor should now be on and rising in temperature and power. Instability should always read 0%. If instability ever reads anything other than 0%, immediately turn off all fuel rods and min/max the gyrotron. Following these 3 steps will ensure you have safely initiated the reactor. It is now producing a small amount of electricity. In the room below the control room, there is the distribution SMES. It is recommended that you upgrade this SMES by opening it with a screwdriver and inserting 1 superconductive capacitor cable and 2 superconductive transmission cables. Be sure to turn on charging and output on this SMES, as it is off by default. Great, we have a working reactor now. However, keeping the reactor in this state will quickly waste fuel and potential electricity. After you complete these 3 steps for reactor activation and are sure everything is stable, continue. Step 4: Power Optimization A minute or so should have passed by now by the time you have activated the reactor. Assuming there hasn't been a catastrophic EMP or meltdown yet, let's move on. Lower the gyrotron delay to 3 and it's power to 2. This will now let the reactor start heating up and producing vastly more power than it was before. Be sure to keep checking the instability and making sure it's 0%. Once the reactor temperature passes 10,000K, you can now begin to inject the hydrogen. The console behind you controls this. Set the flow to 2L/s and turn it on. Hydrogen should now be pumping into the reactor. You can check this on the center console in the 'reactants' section. If it's not appearing at all, make sure the gas pump in the chamber is on and that it's pressure is 101.1 kPs. If you haven't turned off the MRSPACMAN generator by now, be sure to do so or it may overheat and explode. The reactor should be self sufficient to run the gyrotron at this point. At this point, the reactor should be safe to leave alone. Assuming no one comes by and plays with any buttons, it will stay stable and it's fuel will deplete. If the shift goes on long enough to reach depletion, all you have to do is turn off the injectors, take out the old fuel rods, and put in new ones. Note that the power output of the reactor increases with how high the fuel depletion is. So for example you can achieve 3.5MW with near 100% fuel, while it will fall to around 2MW around 0-10%. Just like with the SM, every engineer has their own preference on fuel and what is good, and I know some people are going to complain about not inserting a tritium rod in one of the injectors during the reactor activation, as it helps to kickstart the reaction faster. I simply do not use tritium, as it is more unstable and you may have to play with they gyrotron settings if you use tritium rods. It is up to you. Step 5: Shutting Down The Reactor The shift is coming to an end and it's time to start powering down the reactor. This is a substantially longer process than the SM and the main complaint many people have with the R-UST, as it is often seen as the factor that makes it unsafe. However, powering down the reactor is largely a waiting game, and has only a few steps. Turn off all fuel injectors. Min/max the gyrotron, 2 delay - 50 power. Wait. To successfully power down the R-UST with no repercussions, you must wait for the gyrotron to cool the reactor temperature to below 1000K. ATTEMPTING TO TURN OFF THE FIELD GENERATOR AT ANYTHING MORE WILL RESULT IN A MASSIVE SHIP-WIDE EMP. DO NOT DO IT. Once the temperature falls below 1000K, it is simply a matter of turning off the field generator. The reactor is now completely turned off. Turn off the gyrotron and gas injection. It is wise to remove any fuel rods out of the injectors after powering down, especially if it's in the middle of a shift, to ensure someone cannot potentially sabotage the reactor even when it's off. Also remove the hydrogen canister and turn off the fuel pump. Well, that's basically the whole thing. The R-UST is a largely misunderstood and feared machine that isn't used very often out of pure fear of sabotage. When managed correctly and secured, the reactor is a very valuable backup power system, and can even have experiments done on it by the research department. I want to add an obligatory 'Thank you' to Senior Engineer Emily who taught me how to use the R-UST in the first place. Bye everyone!
