A pile that large of enriched uranium would already be supercritical. It would have killed everyone involved in piling it up with radiation doses in the 10,000 REM range (almost instant neurological death) and have completely melted down and caught itself on fire, dispersing as uranium oxide smoke.
There would be no pile for the warhead to "hit".
No nuclear energy, no nuclear weapons
you can't
It would probably create a localized ozone hole.
Whenever north Korea decides to doo something stupid.example:shooting a nuclear warhead.
Crysis Warhead happened in 2008.
No, nuclear chain reactions can happen in several types of fissile materials, not just uranium. Other examples include plutonium and thorium. These materials can undergo fission reactions and sustain a self-sustaining chain reaction.
Mainly because only about 0.7% of uranium is the isotope uranium-235, which is easily fissionable. It is believed that in Earth's remote past, there were such chain reactions - natural reactors - at a time when the percentage of U-235 was higher.
plutonium can only form from uranium in a nuclear reactor. since the last natural reactors on earth shut down about 3 billion years ago (oklo) it can't happen naturally now.
If uranium ore didn't exist, we would not have access to uranium as a fuel source for nuclear power plants. This could potentially impact our ability to generate electricity from nuclear energy, leading to increased reliance on other forms of energy production. Additionally, uranium is used in some medical applications and in military settings, so its absence could also impact these areas.
Fission in Uranium would take billions of years when its left to its own devices. Because of radioactive decay, it would either release alpha or beta radiation, or fission. The earth would have to be really old for that to maybe happen. Besides, Only less than 1% of Uranium is U-235, which is the only isotope of uranium that would fission, is found on earth.
If uranium is overheated, it can lead to a range of dangerous outcomes, including the potential for a nuclear meltdown in a reactor. Excessive heat can cause the uranium fuel to degrade and release radioactive materials, posing serious health and environmental risks. Additionally, overheating may result in structural failure of containment systems, increasing the likelihood of a catastrophic release of radiation. Such scenarios underscore the critical need for effective cooling and monitoring systems in nuclear facilities.
Usually uranium enriched with the U-235 isotope, in the form of uranium dioxide. This is better than metallic uranium as it can stand higher temperature. Plutonium-239 can also be used if available, this has to be separated from spent uranium fuel by chemical means.
