also heavier wheels draw a lot more power, I use Boron because it is somewhat light and fairly strong, in fact boron has replaced my use of Diamond in a lot of roles

Hey could someone who has experience with reactors help me with something? I'm trying to design something that produces ~10 kilowatt+ range energy, but with the restrictions of being no larger than 50x50x50 cm, weigh no more than 25-55 Kg, and most challengingly have minimal heat output temperatures, without creating too much excess heat. And as if that wasn't enough, I would prefer as low radiation leakage as possible, but it might be easier to just make a ship and surround it with some Lithium-6 This is going to help with part of my next big thread, so you'll see why I need these parameters then (If you don't figure it out on your own by then) Thanks  |

Could I see the 1 MW reactor too please? If it fits the size requirements, I might be able to stretch my other limitations for that much power. Thanks a ton! |

It is listed on the main thread but here it is again you can add as much boron nitride neutron reflector as you want to lower the radiation hazard:  |

Here's my improvement on the 13.9 watt hydrogen (Which I'm pretty sure was based off of my design in the first place), can be neutron fluxed all the way up to about 30 watts I believe but I don't do that because I use it on the smallest possible radiator. It's the same price but 2 grams lighter.  |

It's the same price but 2 grams lighter. Pretty sure you based it off my design (as you stated in the Unlimited Power thread) and then I improved it further by going Hydrogen... This is the reactor for my microdrone, been playing around with it a lot since it's most of the cost of the drone. Jasonvances small ethane reactor gave me the idea to use a criticality changing coolant to make the chamber smaller, which shaved 8 grams off of it. Anybody want to give a shot at making it lighter/cheaper? Needs to be at least 12.5 watts or so.  |

I remember now, that reactor was my own design, but I changed the coolant when I saw what you had done with yours.

Enderminion - Why would you use 2000 K output temperature? It increases radiator surface area and thus mass beyond optimal. (Optimal is around 2400 K.)

I didn't tessfield did, I just made them output slightly more power IIRC, all of the 1 MW reactors are standardized around either 2400 K or 2500 K output temperature. Also, tessfield never created a 1 MW reactor that had a 2000 K output temperature. And while the Small Rod Reactor does have a 2000 K output temperature, there's no reason to use it when you can save credits and kilograms on radiators by using the 70 kW design I submitted, which produces just under 42 more kilowatts of power than your design, whilst being (assuming mass is identical to that of tessfield 's reactor) a full 1.09 kilograms lighter. Admittedly, the 70 kW GPR is more expensive than the Long Rod Reactor, but this expense is offset by the massively increased power output and more optimal radiator output temperature, meaning that you need fewer/smaller radiators than you would with your Long Rod Reactor variant. |

the 1MW SAF reactor, may have misread the output temp, but I can handle the heat with 23kg of radiators and lose half of it with no problems. Smaller reactors can use lower output temps because, for me at least, less then 50kg of radiators is not noticeable, I don't care about a 5-20kg difference in mass when my drones mass 40 tons anyway.
Edit: I swear the link said 2000k, but I can't check because the site is blocked by school internet for "prohibited adult orientated content"
Edit 2: yes the Imagur link said 2000K

For low output temp reactors Platium Tungsten thermocouples are better then Osmimum Tungsten Thermocouples, while low output requires large radiators they are more effiecnt pound for pound (discounting radiator mass)
My spelling is bad, Platnium the computer metal that is spendy IRL, the spanish called it little sliver or something
