It should be noted that the NSWR ship has 2 orders of magnitude higher heat output than the NTR ship. Also, do you think a fission fragment rocket is possible using similar methods? That heat output is actually much higher than the the total energy output of the reaction in the chamber. It seems that the game makes some bad assumptions about how much heat the exhaust radiates, causing the heat signature to violate conservation of energy. Fission fragment might be possible. Trickier than nswr though- the game didn't like my attempt to implement liquid uranium dioxide. |

Can you add a 90% HEU version NSRW nerd1000?  BECAUSE I WANT A STARSHIP!!!~ |

Can you add a 90% HEU version NSRW nerd1000 ? BECAUSE I WANT A STARSHIP!!!~ You're not happy with your Terawatt range fission drive that has more exhaust velocity than an ion engine and provides enough thrust to lift off from Earth? Kids these days don't know how easy they've got it. Back in my day we only had chemical rockets, and we liked it! More seriously, I might give it a go (keeping in mind that your ship will be even more expensive and prone to exploding like an atomic firecracker). I'm also thinking of a 'cut price' bipropellant version of the existing rocket where the fuel is augmented by straight water, reducing Isp but increasing thrust and saving on the costly fissionables (Note: as far as fissionables are concerned the engine I implemented is very wasteful- only 0.1% of the U-235 in the fuel undergoes fission). If we're gonna seriously use this we also need to work out a way of accounting for the engine's radiation output. Maybe build a fast neutron reactor with the same thermal power as the engine and no neutron reflector to get a ballpark figure, then add enough radiation shielding to protect against that? |

Sorry and THX for helping us for so long... and I get really excited about the interstellar fission drive~ |

... and this engine is overall far more believable than the Fusion Torch drive. ... Yea and that why i prefer NSWR than the fusion drive. You know , REALISM!!! And it is a great thing for the forum to have a guy that know about coding and NUCLEAR physics~ |

If there is anywhere you're not sure about the values you've used, or that you figured it out of thin air, please put a '//?' behind it. Don't know how would it affect in CDE, but this is how coders insert irrelevant texts.

And it is a great thing for the forum to have a guy that know about coding and NUCLEAR physics~ Would it be possible to blend a NSWR with a fusion drive? Use a mix of water with uraniumsalt and fusiles to get a fission reaction, which catalyses a fusion reaction. |

It would probably just get blasted out the exhaust before significant fusion occurred. |

I was thinking the X-rays from the fission would ignite the fusion, and that fusion occurs swiftly enough that the fusiles can't disperse too much before undergoing fusion. Somewhat like a Teller-Ulam device. But continuous, and strapped to your spaceship. |
