The operating crews on site at Fukushima are certainly at risk, in order to approach the faulty reactors and fuel storage ponds they are getting more radiation dosage than would normally be allowed. As far as the general public are concerned, provided they follow advice and keep out of the local area around the plant, they are probably not at any significant risk compared to normal life.
nuclear reactors are not very safe at all. the nuclear energy buisness basically went to crap after the three mile island accident, because people decided the risks outweigh the benefits
In everyday life (as most people define it) plutonium has no use. Its primary use is in making nuclear weapons. It can also be used as fuel in nuclear reactors instead of or in addition to uranium, but except for small mostly experimental reactors and the French standardized nuclear reactors for power plants these are almost nonexistent.
Before the Fukushima Daiichi Disaster, there were 54 operational nuclear reactors in Japan. Three of those melted down, and one had problems that rendered it inoperable. The government has decided the other two reactors at Fukushima Daiichi cannot be restarted. Also, as other reactors have been shut down for maintenance or refueling, they have not been restarted, with the result that now, in early December 2011, only eight Japanese reactors remain in operation.
People are managing nuclear energy by utilizing advanced reactor designs that enhance safety and efficiency, such as Generation IV reactors and small modular reactors (SMRs). Additionally, there is ongoing research into nuclear fuel recycling and breeder reactors, which can extend the life of nuclear fuel by reusing spent fuel. Regulatory frameworks and international cooperation also play a crucial role in ensuring the safe and sustainable operation of nuclear facilities, while public awareness and acceptance are increasingly emphasized to support future developments in nuclear energy.
Nuclear reactors can vary in size depending on their purpose. A typical commercial nuclear reactor used for generating electricity can be around 1,000 megawatts in size, which is enough to power a city of about one million people. Small modular reactors (SMRs) are also being developed that can be much smaller in size, around 50-300 megawatts.
They are supposed to design reactors such that when a water pipe breaks or the power fails, the generating station does not explode.
For the first time californium is obtained with the nuclear reaction:Cm-242 + He--------------Cf-245 + nThe important isotope Cf-252 is obtained in nuclear reactors after a long time irradiation of plutonium with neutrons.
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.
No, nothing happened like melting of people in Chernobyl nuclear reactor accident.
Neptunium has only limited uses:- precursor in the preparation of plutonium-238- sensor in the detectors of high energy neutronsIn USA are studied applications of neptunium in nuclear weapons or as nuclear fuels for fast reactors.
its an opinion but id prefer Tokyo because the people know a good amount of english and the food and housing is very nice.
Plutonium is primarily used by nations for nuclear weapons and nuclear reactors. It is a highly regulated material due to its potential for use in weapons. Scientists also use plutonium for research and testing purposes.
