What has happend to the nuclear reactors in japan after the recent tsunami?
Some have become seriously damaged, and others just damaged beyond repair. This will require assistance from international experts to solve these complex and dangerous problems. Others have been down this path before and this expertise should not be ignored. This large quantum of energy will have to be replaced in the electric system.
What are the risks of nuclear reactors?
It is like a spreading atoms. When atoms is hit with another, it will spreading into other atoms and become bigger. That is why it is so powerful...
Why has technetium become so cheap?
Technetium has become less expensive due to advancements in nuclear technology, specifically the development of more efficient methods for producing it in nuclear reactors. Additionally, increased supply from reactors and recycling programs have helped reduce the overall cost of technetium production.
Does nuclear fusion create radioactive waste?
Nuclear fusion does not create long-lasting radioactive waste like nuclear fission does. However, some materials used in fusion reactors may become radioactive and need to be handled carefully.
Is nuclear reactors using U-235 renewable energy?
No, all the uranium on earth was produced in supernova explosions that occurred more than 6 billion years ago, there is no more arriving on earth (except small amounts in meteors and they got their uranium from the same supernovas as did earth). Without building reactors that burn plutonium if we use up all the uranium-235 it will become impossible to build a nuclear fission reactor (nuclear fusion reactors might become possible someday, but not yet).
Why would nuclear power plants using fusion be potentially better?
Nuclear fusion combines hydrogen atoms into helium atoms. Hydrogen is available from water and helium is an inert gas. When fusion reactors become technologically feasible, we will greatly reduce consumption of limited fossil fuels and production of greenhouse gases. Fusion reactors will not produce high level nuclear waste.
Is helium produced only in the cores of stars?
No. Helium nuclei are a common product of nuclear fission, as takes place in nuclear explosions and reactors. These nuclei then pick up electrons from other atoms and become whole helium atoms.
How could eggs become contaminated?
They can be contaminated by the chicken if the chicken has pathogens.
Does the water used to cool a nuclear reactor get contaminated?
In a properly operating nuclear reactor, water used to cool the reactor is not contaminated. This water, called primary coolant, is quite pure. And after shutdown and cooldown, the water has little radiation in it. But if the reactor has some malfunction that overheats the fuel, fuel elements can rupture or melt (a meltdown) and fission products, which are hightly radioactive, can be released into the coolant (the water). The water is then contaminated.
Does the geiger muller tube become radioactive?
no. as with anything in a contaminated area its surfacemay become contaminated, but this can and should be washed off.
What happens to ground water after a nuclear test?
After a nuclear test, the ground water can potentially become contaminated with radioactive materials. This contamination can persist for a long time and pose risks to human health and the environment. Monitoring and cleanup efforts are typically required to address the contamination and protect groundwater quality.
What happens to populations when water supplies become contaminated?
Everyone will become sick.
