Indeed I used that approach with the min cost ones I posted (did a 95t real quick for science). But I think the small size one zorbeltuss made would be a bit better for firing out of a coilgun due to the smaller radius. Thank you for the welcome. ^^ The intention was to use it in a missile made for a coilgun, the problem I have though is that I can't make a coilgun work. But here's a reactor I made in the same formfactor. ^^ Reactors are pretty tricky heh. You might want to go for a bit higher efficiency on your thermocoupler (the % efficiency value on the top left is the total heat generated / how much the thermocoupler extract in the form of energy). Be sure to take note that it doesn't include the power lost to your turbo-pumps so if those start draining too much power you will end up losing over all power efficiency in the turbo-pumps (I kind of wish the game showed the total reactor efficiency as well as the thermocoupler efficiency). I think the hardest part of reactors is finding a nice stable reactor dimensions that can handle the most neutron flux for a specific fuel rod mass and coolant (usually sodium except in the smaller reactors). You could improve your current design by reducing the thermocoupler size to 1cm x 1cm (min size since it isn't near yeild stress limits yet). If you wanted a reasonable starting place for a kw range reactor this one should work pretty nicely:  |

@zorbel
For small reactors, using ethane lets you shave off moderator (if any) and fuel mass (and crank up intensity to compensate, which saves you money on fissiles), which is cool but a complex balancing act.
Also, small reactors can have a lower outlet temp than 2000k since their total heat has a hard time saturating even miniradiators.

Question: why are you people desiginig reactors in the 200-300 watt range that are bigger and not neccessarly cheaper then their 1 kW range counterparts?

Question: why are you people desiginig reactors in the 200-300 watt range that are bigger and not neccessarly cheaper then their 1 kW range counterparts? I assume they are practicing reactor design. Other reasons could be mass-optimization (over cost optimization) or form-factor balancing. Or they could be space hipsters. |

Actually their reactors are about 6 times heavier than the 1kW range so I guess they are space hipsters. |

tiny tiny gun drones, that why  you only need a couple of W to run the loader of a 1g/1.8km/s cannon, any more and its weight baloons |

now here is a request for all those reactor engineers:
make the most powerful mass efficient reactor possible that can function with just a
.1x.1 lithium radiator
or
.1x.1 (whatever) radiator
whichever is more mass efficient, the goal is to get a tiny power system putting out much power for minimum(100-150g) mass
the system is to be mounter on a drone with a
~1.5-2.5kg gun
~1kg fuel
~100g thruster
~100g armour
for a total of: 4kg or less
all will bow before the machine swarm!

Unless you want a low power laser, any firearm might not be able to carry any considerable amount of ammunition.I think I may have gotten something that works.  You could trade barrel length for more ammunition. |

1 kg of ammo = 1000 "standard" rounds. I think we're good.

You can't use less than 2 grams for a firearm, and a rail gun or coil guns minimum power is 1kW. Plus it's not just going to be 2kg for 1000 rounds, because you have to take in consideration the container the ammunition is in. I'm thinking you could do a separate ammunition storage made out of lithium to save on weight since an attached ammo bay seems to use what ever material the barrel is made out of, if not probably the standard aluminum. I figured out I was wrong pretty quick and edited the post.
