The most common isotope of uranium, 238U, has a poor cross-section (the ability to assimilate neutrons) for slow neutrons. In order to enhance the reaction, we enrich the uranium to 235U, from a natural level of about 0.7% to about 4%. This enhances the ability of the uranium to participate in a fissile reaction, i.e. one that sustains neutrons that fission atoms which creates neutrons, etc.

What is the name of the fuel used in the nuclear reactor?

The fuel used in a nuclear reactor is typically uranium. Specifically, the most common type of uranium used is uranium-235, which undergoes nuclear fission to produce energy in the reactor.


What element is a reactor fuel?

Uranium-235 or Plutonium-239, or Uranium-233. Also many transuranics, like Americium make good fuel.


Why must uranium be enriched before it can be used as a fuel source in a nuclear reactor?

Uranium must be enriched to increase the concentration of uranium-235 isotope, which is the isotope that undergoes fission in nuclear reactors. Natural uranium primarily consists of uranium-238, which is not as efficient at sustaining a nuclear chain reaction. Enrichment increases the proportion of uranium-235, making the fuel more suitable for use in reactors.


The fuel used in a nuclear reactor usually comes from?

Mines, usually it is uranium, with only 0.7% (aproximately) U-235 (the isotope that is used for fission), the rest is U-238, known as depleted uranium, or natural uranium. Then it enriched to about 3-5% U-235, unless it is used in a CANDU reactor, in which case it can almost literaly be used straight out of the ground.


How much uranium 235 is used in a nuclear reactor?

The amount of uranium-235 used in a nuclear reactor depends on the design and size of the reactor. Typically, a reactor core contains several tons of uranium fuel, with the concentration of uranium-235 ranging from 3-5%. The fuel is arranged in fuel assemblies to sustain a controlled nuclear fission chain reaction.

How many pounds of uranium are in a nuclear reactor?

The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.


How much uranium is need to power a nuclear power plant for eighteen months?

Depending on: - the type of the nuclear reactor - the electrical power of the nuclear reactor - the type of the nuclear fuel - the enrichment of uranium - the estimated burnup of the nuclear fuel etc.


How much uranium is used per day to power a 1000 MW reactor?

A 1000 MW nuclear reactor typically uses about 25 to 30 tons of uranium fuel per year. This equates to approximately 68 to 82 kilograms of uranium consumed per day, depending on the reactor's efficiency and operational conditions. The exact amount can vary based on the reactor design and the enrichment level of the uranium used.


Why does uranium ore have to be enriched before its used in a nuclear power plant?

1. Uranium must be refined to obtain "nuclear grade" uranium. 2. The enrichment in the isotope 235U depends on the type of the nuclear reactor; some reactors (as CANDU) work with natural uranium.

Does CANDU reactor use enriched uranium?

CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.


How many kilos of uranium in a nuclear reactor?

The amount of uranium in a nuclear reactor depends on its size and design. On average, a typical reactor may contain several tons of uranium fuel in the form of uranium dioxide pellets that are stacked in fuel rods. For example, a 1000-megawatt nuclear reactor may have around 100-150 tons of uranium fuel.
