Nuclear Energy

No, normally it occurs at temperatures of millions of degrees. It does occur at room temperature, but not in significant amount; any possible practical use of "cold fusion" is, so far, speculation.

Nuclear fission occurs in the reactor core of a nuclear reactor. This is where nuclear fuel, typically uranium, is arranged in such a way that it sustains a chain reaction of splitting atoms, releasing energy in the process.

Tritium decontamination techniques for machine components and their application at tritium handling facilities are reviewed. These include commonly used methods such as vacuuming, purging, thermal desorption and isotopic exchange as well as less common methods such as chemical/electrochemical etching, plasma discharge cleaning, and destructive methods. Problems associated with tritium contamination of walls and use of protective coatings are reviewed. Tritium decontamination considerations at fusion facilities are discussed.

In nuclear fission it is the nucleus of the atom that splits, not a molecule, and this releases neutrons and energy. Reactions at the molecule level are termed chemical reactions, not nuclear, and these chemical reactions involve whole atoms and molecules.

Nuclear energy is the energy released when atoms are either split apart in nuclear fission or fused together in nuclear fusion reactions. This energy is harnessed in power plants to generate electricity.

Uranium is actually enriched as a gas, uranium hexafluoride. This is then chemically treated to turn it into a solid material, in most reactors it is uranium dioxide that is used as fuel. In PWR and BWR designs (and AGR in the UK) it is made into small cylinders 10mm diameter which are then stacked end to end inside a sheath, to make a fuel rod. So to describe this as "pelletts" is not quite accurate.

a neutron, causing it to split into two lighter atoms, release additional neutrons, and a large amount of energy. This process can trigger a self-sustaining nuclear fission reaction in a controlled environment, such as in a nuclear reactor.

Any Saskatchewan potter who wishes to have a yellow glaze on his/her pots will employ a glaze that contains Uranium.

Other than that, the uranium is shipped out of Saskatchewan to power nuclear reactors in other provinces and countries. Mines in some areas were closed in the 1980's but exploitation of large ore bodies later began at the Athabasca Basin in northern Saskatchewan.

Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.

Yes, they are quite different. The deuterium-tritium reaction produces a helium nucleus, which is harmless. There will be an intense neutron bombardment of the enclosure holding the fusion plasma, and this will result in the structure becoming radioactive, but that will be a problem for decommissioning rather than operation.

Scientists originally promised fusion as a clean source of energy, and whilst it is not entirely so, it is far cleaner than fission. The only problem is finding how to make it work in a practical power producing plant.

Yes, during a nuclear fission reaction, a nucleus splits into two or more smaller nuclei, releasing a large amount of energy in the process. This energy is released due to the conversion of mass into energy as per Einstein's famous equation, E=mc^2.

During a nuclear reaction, the total number of protons and neutrons (mass number) remains constant, as well as the total charge (atomic number) of the atoms involved. The total energy before and after the reaction also remains the same, as dictated by the law of conservation of energy.

A lamp or an X-ray tube cannot be used to "add neutrons" to other nuclei because lamps and X-ray tubes are not neutron sources.

Neutron activation is generally something we do in an operating nuclear reactor. In the core of the reactor, there is a high neutron flux. Many, many neutrons are being released in the fissions that are going on in the nuclear core. Materials that are to be activated are lowered through ports and brought down into the neutron flux. Activation occurs. Lamps or X-rays do not produce neutrons, and cannot be used in neutron activation activities. No neutrons means no neutron activation.

Radiotracers generally have short half lives. Detection requires a number of decay events. Using material with a short half life means a smaller amount is required and that after the detection the amount of residual radiation is reduced.

Helium-4 can be a product of fusion. Hydrogen-1 cannot be produced by fusion. The uranium isotopes were probably produced by fusion in some star, long ago, and possibly not as uranium, but as something that decayed into uranium. I suppose it would be possible to produce the uranium isotopes in a lab by fusion, but I cannot imagine anyone do so, unless it was to prove a point.

Yes, the chain reaction of nuclear fission can be controlled by using control rods made of materials like boron or cadmium that absorb neutrons, thus regulating the rate of fission. Additionally, cooling systems can also be used to control the temperature and prevent the reactor from overheating.

Neutrons from fission have a natural energy of about 2 Mev. In a thermal reactor these are slowed to thermal equilibrium by a moderator, at about 0.025 ev.

At these lower energies (= slower speeds) we have more time to have them react with a measuring device, commonly a particle detector. Or a scintillation detector with associated light detector..

Two elements are combined together in water: hydrogen and oxygen. Water has a chemical formula of H2O, which means each water molecule contains two hydrogen atoms and one oxygen atom.

Nuclear fission is primarily used in nuclear power plants to generate electricity. It is also used in nuclear weapons and in some medical treatments, such as cancer therapy. Additionally, nuclear fission is used in research reactors for scientific experiments and to produce radioisotopes for various applications.

To initiate nuclear fission, a nucleus must absorb a neutron, leading to its instability and subsequent splitting into two or more lighter nuclei, along with the release of additional neutrons and a large amount of energy. Additionally, a critical mass of fissile material, such as uranium-235 or plutonium-239, must be present for a sustained chain reaction to occur. The process is typically moderated by materials like water or graphite to control the rate of fission.

This is due to the fact that the forces between nucleons are very strong - much stronger than the forces between atoms in a chemical reaction for example.

A major drawback of nuclear power is the risk of accidents, such as meltdowns or leaks, which can have serious environmental and health consequences. Disposal of radioactive waste is another significant challenge associated with nuclear power generation. Additionally, nuclear plants require high upfront capital costs and take a long time to build, making them less flexible compared to other forms of energy generation.
