Is it even possible to go past 2.20e+020 neutron flux and still have the reactor run for long enough?

What happens when you try and use it in a nuclear reactor?

I've been encountering a weird issue where some of my custom coilgun designs refuse to fire at all, even when an enemy target should be in their range or the ignore range command is selected. Additionally, no range indicator pops up for these weapons on the right hand side of the screen, even though there should be an indicator present.

apophys ty for the 25GW reactor design, you inspired me to do this (SNIP)(SNIP 2)Its weight and cost are low enough you can bring it on Vesta Overkill, and the MPDs can push it at 20 mg (only time they are marginally useful) Uh... Jesus fucking Christ seems appropriate? I mean, just.... you have 120 GIGAWATTS worth of lasers on that thing. WHY DO YOU NEED THAT MANY LASERS?! ... Can you also share any of the unique modules you're using for that ship? I want to see if my computer can handle it. Or the user design thingy for it?

What kind of engines is everyone using for moving big ships? A lot of the early favorites in this thread no longer work. I've tried my hand at it and while I can get high velocities and thrust they're horrific gas guzzlers. I've been using a Methane NTR. I think I posted it in the "Bigger NTR" thread, but I'll see if I can dig up the documentation I have for it. EDIT: It was in the Really Powerful NTR design thread, but here it is. Mass and Cost Breakdowns, Thermal Rocket, and other componentsHere it is if you want to try using it for yourself.

Lowering reactor output temperature will always increase output power. This is not a straight upgrade, however, because it also increases the radiator area required. If you have 4x redundant radiators, for example, the above change is overall a downgrade. Radiator inter-reflection acts much like redundancy, too. Maybe include a column for the minimum amorphous carbon radiator mass & cost associated with a reactor, so that people can decide how much redundancy they like and choose based on that? From what I've heard, 2400 Kelvin is the most radiator efficient output temperature, at least for reactors and the like, period.

Thanks for the upgraded reactor ash19256 ! I'll update it now Thanks for the tip targetx ! I'll add it too! You should probably hang onto the reactor I used as a base for that one, and just add a note saying to change the output temperature. That's the only change I made, and it's a pretty simple tweak to do when recreating the listed reactor.

Not really. I was sort of planning to figure that out once staging was added, because even the proposal two variant, with 500+ km/s of delta-v couldn't get you on a trajectory for the nearest star system with planets that the folks from Children of A Dead Earth could make habitable. Was planning on using a NTR first stage to kick them out towards their destination, and then they'd use the main engines to decelerate on arrival.

Yeah, this glitch has bitten me a few times, I mostly solved it by changing barrel materials or tinkering with the bore radius.

That's because I was using the 10 MW Long Rod Reactor designed by tessfield as a base. Here's the version created when I took the currently listed reactor and changed the output temperature.

Could we get a look at the rest of the reactor? I have some ideas for making that reactor more efficient. It might not actually do anything, but at the very least it might create a version that doesn't make my inner engineer scream with rage. I never actually saved the original, because it was a joke due to the silly mass, but it's pretty easy to rebuild a similar one. Dropping the temperature to 2300K immediately gives it a nice round output of 40.1 GW (Further drops give further rise in output. Lower temperature than this is a problem for radiator area, but if you're actually considering this reactor, you may not care about that). Code: ThermoelectricFissionReactorModule 40.1 GW Thermoelectric Fission Reactor ReactorCoreDimensions_m 0.5 0.48 NuclearReactor Coolant Sodium Moderator Boron Nitride ModeratorMass_kg 0 Fuel U-233 Dioxide FuelMass_kg 367 FuelEnrichment_Percent 0.97 ControlRodComposition Boron Nitride ControlRodMass_kg 440 NeutronReflector Diamond ReflectorThickness_m 1 AverageNeutronFlux__m2_s 2.2e+020 InnerTurbopump Composition Amorphous Carbon PumpRadius_m 20 RotationalSpeed_RPM 10 ThermocoupleInnerDimensions_m 30 30 Thermocouple PTypeComposition Tungsten NTypeComposition Tantalum Length_m 0.001 ThermocoupleExitTemperature_K 2300 OuterCoolant Sodium OuterTurbopump Composition Calcium PumpRadius_m 20 RotationalSpeed_RPM 9.7
Honestly, I was never really serious about using it for much. I did use it for a thing I just posted to the Post your designs here thread, but other than that I only wanted to try and optimize the turbopumps. Unfortunately, for whatever reason, to spin a smaller pump faster takes more power than spinning those 20 meter radius pumps at ~10 RPM. Which is bullshit, but whatever. Good job on making these things as powerful as they are.

Here's a revamp of the 10 MW LRR that produces slightly more power. Only had to drop the output temperature by 100 K, from 2500 K to 2400 K.

Good thing that when I recreate it I don't intend to fire it at those ludicrously high rates of fire.

Did you guys not notice the efficient 25.1 GW reactor I posted ON THIS VERY PAGE (and reposted in the standards thread)? xD Also, a very old post in the thread that pushed the limits on power with no regard to mass (could possibly be better with lower temperature): How about 37.6 GW? The limiter is turbopump energy consumption. If you spin them faster to cool more, they eat more power than the cooling helps with. Could we get a look at the rest of the reactor? I have some ideas for making that reactor more efficient. It might not actually do anything, but at the very least it might create a version that doesn't make my inner engineer scream with rage.
