In addition to the other replies: to get useful energy out of the reactor requires converting thermal energy to electrical or mechanical energy. Direct conversion to electrical energy (thermo-electric effect etc.) is orders of magnitude too ineficient for the power to weight and power to volume ratios you are looking at. So you would need something like a ...

Fusion is nuclear power too. https://www.lockheedmartin.com/en-us/products/compact-fusion.html The MIT ARC reactor is a torus 3 meters across and will in theory produce several hundred megawatts. So several orders of magnitude more power than you request but you will find something to do with it. Specifics on the Lockheed reactor are not as easy to find ...

The reactor itself, is doable... The amount of highly enriched uranium required to sustain criticality is not massive. Although it can be done with a few dozen kilograms (less if you use plutonium), you would never actually be able to build a reactor this small for practical reasons: More fuel is needed to extend the life of the core. Reactivity decreases ...

This ought to be doable, but the technology may not be published Proposals for "miniaturized nuclear plants" generally involve megawatts of power produced by reactors that are too large for your purposes. (And they still sound like a very bad idea) The one I linked is perhaps typical in power, and is 9 feet in diameter and 65 feet long, though ...

With the current parameters it's impossible Nuclear reactors are big. Miniaturisation of such technology isn't easy, making a maximum of 2 liter volume reactor impossible. You need more for cooling alone. The closest we can do are radioisotope thermoelectric generators. They are sometimes referred to as nuclear batteries and are commonly found on sattelites ...

How dystopian do you want your story to be? If it's an environment with harsh penalties for crime then you have a instant source of candidates to send into the radioactive wasteland. What would make these people go into these places knowing it's going to be a death sentence? Use their families as leverage. This way, the technology they have available doesn't ...

Several good answers address the gear considerations. Some considerations around who to send: Older is better than younger. Lifetime radiation dose is more of a problem earlier on in life than much later in life. Sterile is better than fertile. Getting a big radiation dose is more of a problem for the breeders and their offspring. Conveniently, this ...

Stay Up High In a post-nuclear-apocalypse city, there will be (remnants of) skyscrapers and other tall buildings. These become your highways. The big radiological concern is avoiding places where contamination (radioactive dust, basically) will collect. Contamination is more likely to collect in a depression, or a low space with limited outflow. So the ...

Keep the radioactive dust out of your food and water, and especially out of the air your breathe. Even a simple wetted-cloth facemask will filter out 99%+ of the bad stuff. Wear gloves, longsleeve clothing, head cover, goggles. Again, the purpose is to make radioactive dust settle on the clothing, which can be discarded, rather than on your skin. At every ...

Others have covered the necessity of keeping radioactive dust off of and out of the explorers. I will only add that KN95 masks and other specialized filter masks used for commercial, non-medical applications (construction, painting, etc.) seem likely to be the highest availability for creating jury rigged fallout protection gear in your hypothetical ...

Preliminaries The irradiation danger depends on the energy of the bombs, their make up and the altitude of explosion For a 15-20kt range, uranium/plutonium A-bomb (like the Hiroshima/Nagasaki), exploding at 500m: the area of total destruction is about 2km, you have no reason to get there, unlikely that something that one needs survived intact the "hot ...

Whenever they go out exploring they would need to wear some full body suit, breathing mask included, to prevent accumulating radioactive dust on themselves. Together with that they should enforce a strong separation between what's worn in the outside (potentially radioactive environment) and what is worn inside (safe environment). If they have a supply of ...

idk, would like to keep it as a comment, but let it be an extended comment then, as per mod request. (Frame challenge or answer should be posted as such. – L.Dutch♦ 1 hour ago) Yes. There are certain difficulties at moderating the power of nuclear plants according to changing demand, but it is not a problem that stops from building 9x more power plants, ...
