What is artificial nuclear reactor?
An artificial nuclear reactor is a device that initiates and controls a sustained nuclear chain reaction. This reaction produces heat, which is used to produce electricity in nuclear power plants. The fission process in these reactors generates energy by splitting atomic nuclei.
What are some attributes of nuclear fission?
Nuclear fission (as opposed to nuclear fusion) is the process in which a atom is broken into smaller pieces (other smaller atoms). This is different from nuclear decay, in which an unstable particle emits particles in an attempt to become more stable. Nuclear fission can be done on any element, other then hydrogen, however it will not yield energy for anything smaller then Iron. When a large particle, like Uranium, is broken into fissile elements, they don't always break the same way. So you would not always get the same particles. These fissile particles fly off and strike another atom, and break it into pieces and the reaction continues.
Why do you use nuclear fission for electricity?
Fission is used for electricity because it can generate a vast amount of energy (electricity) for very little fuel. Fission also emits no greenhouse gases, or gas pollutants of any kind (all of its waste is solid or suspended in a liquid), thus making it possible to dispose of in safe locations (as opposed to just released into the air with coal plants).
What part particle collides with the nucleus to start the nuclear decay series?
Nuclear decay does not require an initiating event. The instability of of the nucleus causes random decay. This is a result of the fact that the nuclear force (residual binding energy) in larger nuclei starts to be overwhelmed by the electromagnetic force because the nuclear force decreases at a greater rate with subatomic distance than does the electromagnetic force. The nuclear force is an attractive force, while the electromagnetic force, for protons, is a repulsive force, but initially, the nuclear force is nearly 100 times more powerful than the electromagnetic force. At a certain point, specifically around atomic number 83, Bismuth, the nucleus starts to become unstable.On the other hand, if you are asking about nuclear fission, as opposed to nuclear decay, that process is often initiated by the absorption of a neutron, which further destabilizes the nucleus, causing it to split, usually in a 2:3 ratio. The exception is that some isotopes do decay by spontaneous fission.
How nuclear energy is changed into energy?
Nuclear power stations use nuclear fuel to heat water as opposed to oil, gas or coal. That is the basic difference. When fissionable material breaks down it gives off heat, as well as other stuff, that heat is used to heat the water which drives the turbines to produce the electricity.
Should you bomb Iraq with nuclear weapons?
I do not have the power to bomb anything or anyone. As for whether anyone should use nuclear weapons, I am fervently opposed to that idea.
Are there any groups or organizations opposed or in support of flag burning?
The Citizens Flag Alliance is an organization that is against flag burning. They are probably the most notable for that side. Veterans against the flag burning amendment, or something to that degree is an organization that supports flag burning.
What sector is the nhs?
The NHS is a public sector organistion, funded by the taxpayer and with the main goal of providing a service (as opposed to generating a profit as is the case with organisations in the private sector).
Why are so many people opposed to nuclear power?
I guess they think it is dangerous. It can be, as Chernobyl demonstrated, but then other forms of energy are also dangerous. Think of accidents to coal miners, oil refinery explosions, and natural gas explosions.
How would a fusion reactor differ from the nuclear reactor?
A fusion reactor is a type of nuclear reactor, one which fuses hydrogen atoms into helium atoms, as opposed to a fission reactor (by far the dominant source, and the only one used to commericaly generate power), which spilts uranium or plutonium atoms (mostly these two). Both use these reactions to generate heat, turning water to steam which then drives and turbine, which in turn drives a generator, creating electricity.
Why is America apposed to Iran having nuclear weapons?
America is opposed to Iran having nuclear weapons because we see their country as unstable and if they were allowed to have nuclear weapon capability they would either use it against us or sell them to radical terrorist group. At least that's what we believe.
What is fusion as opposed to fission and why does it need high temperatures and fast speeds?
Fusion is putting together (atoms ... usually hydrogen atoms), Fission is the breaking apart of atoms. And fusion requires high energy to occur because it requires the nucleus of atoms to touch (collide) - not an easy thing to do (basically impossible using only chemical energy).
