Everything has a tiny nuclear reactor in it. How much of a concern are illegal nuclear bombs?
In this world, basically every structure (building, factory, car, etc...) has a tiny nuclear reactor in it, and operates like a nuclear submarine. There isn't even an electrical grid; every structure ...

Is there any version of an ion drive, fictional or not, that would be able to create torchship-like acceleration for interplanetary travel? [closed]
Im trying to find a way to get a torch-ship up to some 0.x % of lightspeed with a ion-thrust like engine.
Let assume power is a non-issue, unless its becoming absurd (it makes no sense to propel a ...

How big should this starship's power system be?
I have a near future starship that weighs about 10,000 tons. I've determined that the ship needs a 500 megawatt fission reactor, but the problem is that even though nuclear fuel rods are obscenely ...

The late-victorian nuclear-thruster
Nuclear fission! How hard can that be? Nuclear reactors have been quietly humming under the earth's surface only a few billion years ago after all.
It's very convenient then, that my planet's quite a ...

Could a steam-age civilization trial-and-error their way to a nuclear reactor if they had access to enough fissile material?
I think this boils down to a question of how much fundamental understanding is needed to build a very basic nuclear reactor to boil water.
If fissile material was readily available to an otherwise ...

Can You Make A Tiny Nuclear Reactor By Employing Supercritical Conditions For Brief Periods Of Time?
The idea is that you would have pieces of plutonium or U233 close enough that if left to their own devices they should go supercritical in a fraction of a second. However, in between the pieces you ...
