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.

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?
The positive aspects of nuclear fission are: it is an energy source which uses fuels which will last for a long time. It can produce a large amount of energy from a small energy input. It produces very little carbon emissions. It is often considered to be better for the environment than coal power plants. It produces more energy than coal power plants and most other energy sources.
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.
How do you do an energy balance for a cs-tr?
To perform an energy balance for a CSTR (continuous stirred-tank reactor), you need to account for the energy input (heat, work) and output (cooling, agitation losses, heat exchange with surroundings) in the system. The energy balance equation typically involves the heat generated or consumed in the reaction, the heat capacity of the reactor contents, and the temperature changes within the reactor. By summing up these energy terms, you can determine the overall energy balance for the CSTR system.

What is the principle of a nuclear reactor?
how the nuclear reactor can work? A nuclear reactor is a system which generates a nuclear fission reaction. A nuclear reaction is a self-sustaining reaction where the output of one stage is the input of the next stage. Therefore, if there is enough fuel, the reaction will continue indefinitely. The most common type of fission reaction is a Uranium 236 reaction. Nuclear fission involves splitting an atom into smaller atom(s). In a U236 reaction, Uranium 235 is the fuel. A neutron is propelled, which strikes the nucleus of a Uranium 235 atom, creating a U236 atom. U236 is highly unstable, and undergoes radioactive decay. This means the U235 atom turns into a Krypton atom, and a Barium atom, plus 2 extra neutrons and some energy. This energy is generally heat, and is absorbed by nearby water, which boils and turns a turbine. The two neutrons continue the reaction by hitting another U235 atom (each). There are other types of nuclear reactions as well, but the principle is the same. The output is generally atoms of different atomic mass, energy, and some other byproduct which will continue the reaction (e.g. an alpha particle - a Helium nucleus, or a neutron). In nuclear fission, the atom byproducts have a lower atomic mass. In nuclear fusion, the atom byproducts have a higher atomic mass (since multiple atoms are fused together). Nuclear fusion is the basic power plant in the core of the sun (combining Hydrogen atoms into Helium, or Helium into Carbon, etc.). The byproduct here is the energy that we see as light. Slow neutron fission chain reaction.
What are nuclear power reactors and reprocessing plants?
In simple terms:Nuclear power reactor is an installation where nuclear fuel undergoes nuclear fission process resulting in thermal energy production. this thermal energy is transferred to reactor coolant system. Then the thermal energy converted into mechanical energy through turbines. The mechanical energy is converted to electrical energy through electric generators.Reprocessing plant is an installation where its feed (or input) is the irradiated nuclear fuel (called used fuel or spent fuel) that is discharged from the nuclear reactor. This fuel after successive mechanical and chemical processes is separated into uranium and plutonium (for reuse again) and radioactive waste to be disposed of using specific techniques according to their physical form and radioactivity level.
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?
These days, after 50 years of nuclear power, it is pretty routine, the scientific input is not much. Scientists are still involved in experimenting with different types of reactor and with nuclear fusion, to some extent with extending the life of plants and fuel used in them, and with waste from spent fuel.
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?
The positive aspects of nuclear fission are: it is an energy source which uses fuels which will last for a long time. It can produce a large amount of energy from a small energy input.
