Energy Waste From Split Arom: How Much Is Too Much?

The energy released from splitting a single atom depends on the atom in question. Atomic nuclei have a nuclear binding energy, which means an atomic nucleus has a lower potential energy than the sum of its constituent parts, and this is what holds the nucleus together. Iron (Fe) has the highest binding energy and acts as a turning point in nuclear reactions. Elements with an atomic number less than iron release energy upon fusion, while elements with atomic numbers greater than iron require energy input for fusion but release energy upon fission.

The energy released from splitting a single atom of uranium-235 is about 200 MeV or 3*10^-11J. This is a huge amount of energy, about a million times more than the energy of a photon of visible light. However, while this is enough energy to break chemical bonds in the human body, it is not enough to create a large explosion on a macroscopic scale.

To put this into perspective, it would take ~1*10^17 atoms of U-235 to get as much energy as you could get from blowing up 1kg of TNT. Nevertheless, nuclear energy packs a punch, as the fission of just ~5*10^-8kg of U-235 releases as much energy as the explosion of 1kg of TNT. This mass is smaller than the mass of a human eyelash!

The energy released from splitting a single atom is enough to kill an amoeba

The energy released from splitting a single atom is miniscule and, in the case of hydrogen, requires more energy to split the atom than is produced. However, the energy released from splitting a large number of atoms at once in a nuclear explosion is immense and can be deadly.

Amoebas are single-celled organisms. One species, Naegleria fowleri, is known as the "brain-eating amoeba" because it causes a rare but deadly infection and inflammation in the brain, destroying brain tissue. This disease is known as primary amoebic meningoencephalitis (PAM) and is caused when contaminated water with the brain-eating amoeba travels up a person's nose. It is considered a fatal infection, with 97% of infected people dying.

Therefore, while the energy released from splitting a single atom may be minuscule, the energy released from splitting a large number of atoms in a nuclear explosion could certainly be enough to kill an amoeba.

The energy from one atom is far from enough to create a bang on a macroscopic scale

The energy released from splitting a single atom is minuscule. While it is a huge amount of energy on the atomic scale, it is far from enough to create a bang on a macroscopic scale.

The energy from splitting one atom of uranium-235, for example, is about a million times more than the energy of a photon of visible light. While this is more than enough energy to rip apart chemical bonds in your body, it would take around 10^17 atoms of U-235 to get as much energy as you could from blowing up 1kg of TNT.

To put it another way, the energy from splitting one atom is equivalent to the energy from 1 trillionth of a joule or 1/100,000th of an erg. This is a tiny amount of energy—if four hydrogen atoms were to merge into one helium atom on your finger, you wouldn't feel a thing. It would take thousands of hydrogen atoms fusing on your finger before you began to feel any warmth.

The force holding an atomic nucleus together stores a huge amount of energy. To obtain energy from the nucleus, scientists split a heavy atom into lighter atoms. Because the lighter atoms don't need as much energy to hold the nucleus together, energy is released in the form of heat or light. This process is called nuclear fission.

Nuclear power plants harvest the energy released by splitting atoms in a controlled manner. However, the amount of power generated is much smaller than uncontrolled nuclear reactions, such as atomic bombs.

To create a bang on a macroscopic scale, a chain reaction is required, where the split atom triggers another atom to split, and so on. This is what happens in an atomic bomb, where a large chunk of radioactive material will naturally decay and cause other atoms to decay faster.

Nuclear binding energy holds the nucleus together

Nuclear binding energy is the energy that holds a nucleus together. It is the minimum energy required to disassemble the nucleus of an atom into its constituent protons and neutrons, known as nucleons. The binding energy for stable nuclei is always a positive number, as the nucleus must gain energy for the nucleons to move apart from each other.

Nucleons are attracted to each other by the strong nuclear force, which is a residuum of the strong interaction that binds quarks into nucleons at a smaller distance. The strong nuclear force has a limited range, rapidly decreasing with distance. The electric force, on the other hand, dominates at greater distances, with protons repelling each other due to their positive charge.

The mass of an atomic nucleus is less than the sum of the individual masses of the free constituent protons and neutrons. This difference in mass can be calculated using Einstein's equation, E = mc^2, where E is the nuclear binding energy, c is the speed of light, and m is the difference in mass. This "missing mass" is known as the mass defect, representing the energy released when the nucleus was formed.

Nuclear binding energy can be thought of as the amount of work done in overcoming the strong force and separating nucleons. It is the energy required to break the bond between nucleons. The amount of energy required to break up the nucleus into its constituent particles is its binding energy.

The nuclear binding energy holds a significant difference between the nucleus's actual mass and its expected mass, based on the sum of the masses of isolated components. This difference in mass is due to the energy that is ejected when the nucleus is created, resulting in a mass defect.

The nuclear binding energy curve shows that for elements lighter than iron-56, fusion releases energy, as the nuclear binding energy rises with the increase in mass. For elements heavier than iron-56, fission releases energy, as the lighter elements have higher binding energy. Thus, there is a peak at iron-56 on the nuclear binding energy curve.

Nuclear waste is a downside of fission

Nuclear fission is the splitting of a large atomic nucleus, such as uranium, into smaller nuclei, with the release of energy. While nuclear fission does not release greenhouse gases, it does produce radioactive nuclear waste. This is a significant downside of nuclear power generated through fission.

Nuclear waste is extremely dangerous and can last for a very long time. Radioactive waste requires expensive storage measures, such as deep underground storage, and must be carefully managed and monitored to prevent leaks and environmental contamination. The long-term storage of nuclear waste can be challenging, as it needs to be isolated from the environment for tens of thousands of years. This is particularly concerning in regions prone to earthquakes or other natural disasters that could lead to the release of radioactive material.

The management and disposal of nuclear waste are complex and costly processes. The decommissioning of nuclear power plants is also extremely expensive and requires specialized skills. Nuclear waste storage facilities are often located far from populated areas, but this can increase the cost and complexity of transporting the waste.

Furthermore, the mining, transportation, and purification of uranium ore, which is used as fuel in nuclear fission reactors, release significant amounts of greenhouse gases into the atmosphere. This contributes to climate change and global warming.

In summary, while nuclear fission may offer some advantages in terms of energy production and economic impact, the downside of nuclear waste generation cannot be overlooked. The dangers associated with radioactive waste, the environmental impact, and the long-term costs of waste management and storage present significant challenges that need to be carefully addressed to mitigate potential risks.

Nuclear fusion is another type of nuclear reaction that produces energy without nuclear waste

The amount of energy required to split an atom depends on the atom in question. Atomic nuclei have a "nuclear binding energy", which means an atomic nucleus has a lower potential energy than the sum of its parts, and this holds the nucleus together. Iron (Fe) has the highest binding energy and acts as a turning point in nuclear reactions. Elements with an atomic number less than iron release energy upon fusion, while elements with atomic numbers greater than iron require energy input for fusion but release energy upon fission.

Fusion is considered an environmentally friendly source of energy as it does not produce CO2 or other harmful atmospheric emissions. Its fuel sources, hydrogen and lithium, are also widely available. Additionally, fusion reactors are considered inherently safe as they are not based on a chain reaction like fission. Any shift or change in the working configuration of the reactor causes the cooling of plasma or the loss of its containment, leading to the automatic halt of the reactor within a few seconds.
