It is different for all reactor types, but I'll tell you about the CANDU, as it is widely used, and I know the most about it. Each CANDU reactor holds 4500-6500 fuel bundles at one time, each 50cm long and 10cm in diameter, each weighing about 20kg. Each produces roughly 1GWh (gigawatt hour) of power during its time in the reactor.
The input energy for a nuclear fission reactor is the initial energy required to start and sustain the fission process. This energy is needed to overcome the barriers that hold the nucleus of an atom together and initiate the chain reaction that releases energy through the splitting of atoms.

Why might the following nuclear reaction not be very good for energy production in a fission reactor?
The following nuclear reaction may not be good for energy production in a fission reactor if it produces unstable or short-lived isotopes that can lead to radioactive waste with long half-lives, which can be difficult to manage and store safely. Additionally, if the reaction generates a small amount of energy compared to the input energy required to sustain the reaction, it would not be an efficient or sustainable energy source for a fission reactor.
How are nuclear fission and nuclear fusion are the same?
They are similar only in that they are nuclear reactions. In nuclear fission involves the splitting of an atomic nucleus, whereas nuclear fusion involves the joining together of atomic nuclei.
What are the advantages and disadvantages of nuclear fission?
Advantages of nuclear fission: produces large amounts of energy, low greenhouse gas emissions during operation, and relatively low fuel costs. Disadvantages of nuclear fission: risk of accidents and radiation exposure, long-term radioactive waste disposal challenges, and potential for nuclear proliferation.
Is an input of energy required in order for nuclear decay to happen in an atom?
No, an input of energy is not required for nuclear decay to happen in an atom. Nuclear decay is a spontaneous process that occurs when an unstable nucleus emits particles or energy to become more stable.
What are the main reasons why nuclear fusion have not been used in nuclear reactors?
The main reasons why nuclear fusion has not been widely used in nuclear reactors are the significant technical challenges in achieving and sustaining the high temperatures and pressures needed for fusion reactions, the high cost of research and development for fusion technology, and the lack of a commercially viable fusion power plant design that can produce more energy than it consumes. Additionally, there are safety concerns related to handling and containing the high-energy reactions in a fusion reactor.

What is the principle of a nuclear reactor?
The principle of a nuclear reactor involves the controlled fission of uranium atoms to produce heat energy. This heat is used to generate steam, which drives turbines to produce electricity. The reactor's core is surrounded by a coolant, such as water, to regulate the fission process and prevent overheating.
What are nuclear power reactors and reprocessing plants?
Nuclear power reactors are facilities that use controlled nuclear reactions to generate electricity. Reprocessing plants are facilities where spent nuclear fuel is treated to separate useful materials for recycling and to manage waste products. Both are important components of the nuclear fuel cycle.
What is a source of energy that needs another source of energy to produce it?
Nuclear energy requires an external source of energy to initiate the nuclear fission or fusion reactions that produce energy. This initial energy input is typically in the form of electricity or another type of fuel to start the chain reaction.
Does nuclear energy stand alone or does it work with other sources?
Nuclear energy from fission is determined by the behaviour of the nucleus and is not affected by external conditions, except in so far as to affect the neutron spectrum and hence the efficiency of a nuclear reactor assembly. A nuclear chain reaction depends only on the enrichment of the nuclear fuel, the lattice arrangement of the fuel, and the moderator, and to a smaller extent the temperature of the moderator, it does not require any other energy input to make it start, because it relies on a small rate of spontaneous fissions in the fuel to provide a small starting neutron flux.
How do you calculate the energy output of a thorium subcritical reactor when you know the neutron flux input?
To calculate the energy output of a thorium subcritical reactor when you know the neutron flux input, you would multiply the neutron flux by the energy produced per neutron capture in the thorium fuel. This can be determined based on the specific design and characteristics of the reactor. By knowing the neutron flux input and the energy produced per neutron capture, you can estimate the energy output of the reactor.
Is the nuclear generator 100 efficient explain?
No, a nuclear generator is not 100% efficient. Like other power generation systems, nuclear generators have inefficiencies such as heat loss and mechanical losses that prevent them from converting all the input energy into usable electricity. The efficiency of a nuclear generator typically ranges from 30% to 40%.
Why do scientist use uranium to produce nuclear energy?
Scientists use uranium to produce nuclear energy because uranium is a naturally occurring element with a high concentration of energy in its nucleus. Through a process called nuclear fission, uranium atoms can be split to release a large amount of energy in the form of heat, which is then converted into electricity. Additionally, uranium is relatively abundant and has a long half-life, making it a reliable and efficient fuel source for nuclear power plants.
How are nuclear fission and nuclear fusion are the same?
They are similar only in that they are nuclear reactions. In nuclear fission involves the splitting of an atomic nucleus, whereas nuclear fusion involves the joining together of atomic nuclei.
What is the only element that can theoretically release energy in neither fusion nor fission?
The only element that can theoretically release energy without undergoing fusion or fission is iron. This phenomenon occurs due to the binding energy per nucleon being at its maximum for iron, meaning that both fusion and fission processes would require energy input rather than releasing energy.
What are the advantages and disadvantages of nuclear fission?
Advantages of nuclear fission: produces large amounts of energy, low greenhouse gas emissions during operation, and relatively low fuel costs. Disadvantages of nuclear fission: risk of accidents and radiation exposure, long-term radioactive waste disposal challenges, and potential for nuclear proliferation.
