Is fission process possible on earth?
About 3 billion years ago, when U235 was much more common, it did. Look up the Oklo natural reactors in Africa for an example. There were probably other sites too.Manmade nuclear power reactors.Manmade nuclear weapons.
How long does a kilogram of uranium last inside a nuclear reactor?
The lifespan of a kilogram of uranium inside a nuclear reactor depends on the type of reactor and its operating conditions. Typically, a kilogram of uranium in a reactor can generate energy for several years before needing to be replaced or refueled. The amount of energy generated also depends on the efficiency and design of the reactor.
Fission reactions can be run continously to generate electric power commercially because?
A steady state chain fission reaction is set up in the reactor, when just enough of the neutrons released in each fission is captured by other fissionable nuclei to keep the number of fissions occurring every second at a constant level. Thus the reactor power is held at a steady level. The reactor in terms of nuclear properties is then said to be "critical". As operation proceeds the U-235 gets used up, but this is counteracted to some extent by the production of plutonium from U-238, the plutonium also being fissionable. Eventually the reactor runs out of fissionable material and has to be refuelled, but this can be only at intervals of two years or so, between these refuelling outages the power output can be maintained continously.
What are the consequences of nuclear fission for the earth?
The consequences of nuclear fission for the Earth include the potential for environmental contamination if radioactive materials are not properly contained, long-term storage challenges for radioactive waste, and the risk of accidents or meltdowns at nuclear power plants. Additionally, nuclear fission contributes to the proliferation of nuclear weapons, which poses a global security risk.
What are the risks of nuclear fusion?
The main disadvantage of fusion is that no scientists have been able to contain a fusion reaction long enough for there to be a net energy gain, but nuclear fission is already producing 11% of the worlds energy needs.The atomic bomb.
Why are nuclear waster products a problem?
Nuclear fuel remains dangerously radioactive for thousands of years after it is no longer useful in a commercial reactor.
How long does nuclaer energy last?
Nuclear energy can last for millions of years, as it is generated by the process of nuclear fission, where atoms are split to release energy. The duration of nuclear energy depends on the amount of available nuclear fuel and the efficiency of the reactor.
What three things did nuclear plants intend to do with long-lived fission waste products?
all reactor waste products with lifetimes over a few hundred years make excellent reactor fuel, they should all be recycled and reused in reactors. these are all transuranics, not fission products.
What is nature's nuclear fission reactor?
Oklo in Africa when the natural concentration of Uranium-235 was near 5% instead of the current 0.7%. This was about 3 billion years ago.
How many years of experience do you need to become a nuclear reactor system engineer?
my cousin became a nuclear reactor engineer and he said it was about 12 years
Can fission happen on earth?
Yes, all natural radiation (in the rocks) is a result of fission (but this fission is not part of a chain reaction like in a fission bomb). However, it is theoretically possible for natural processes to concentrate radioactive elements (uranium) to the extent where a natural nuclear fission reactor (a chain reaction like in a nuclear power plant) will form. Oklo in in Gabon is the only known location for this to have happened and consists of 16 sites at which self-sustaining nuclear fission reactions took place approximately 1.7 billion years ago.
Would it be a good idea to build a nuclear power reactor the utilized spontaneous fission why or why not?
No. For 2 main reasons: 1) In a fission reaction the atoms split. Consequently, radioactive waste will be produced ( which is very expensive to store and keep them). 2) It will take billions of years for it to decay.

How many years has nuclear fission been used?
About seventy years.

What power source needs to be replaced every fifty years?
nuclear reactor on ship
What are some uses of nuclear energy?
Nuclear fission produces nuclear waste which has to be desposed off and because of the nuclear waste's long half-life it takes thousands of years before the waste becomes safe. Mining for U-238 is expensive and an enrichment process is required to turn U-238 to U-235 before it can be used in a nuclear reactor, this takes time and money and is another disadvantage.
