How does the uranium used in a CANDU reactor exist in nature?
CANDU burns natural unenriched 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.
Does uranium need to be enriched in order to be used in a nuclear reactor?
Some nuclear power reactors work with low enriched uranium; CANDU reactors work with natural uranium.
How much uranium 235 is used in a nuclear reactor?
Depending on the type and the power of the nuclear reactor. An example; a CANDU type reactor of 700 MW need 700 kg uranium-235 and only ca. 500 kg are "burned".
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.
What type of nuclear reactor is used in Ontario to produce electricity?
This is the Candu type, which was uniquely developed in Canada to use heavy water moderator and natural uranium fuel
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.
Two important functions of heavy water in a candu reactor?
moderator, coolant
What is the half-life of the isotope of uranium used in a CANDU reactor?
CANDU reactors works now with natural uranium.Uranium 235- neutrons: 143- atomic mass: 235,043 929 918 ± 0,000 001 957- half life: 7,038.108 years- concentration in natural uranium: 0,7204 %- 235U is a fissile isotopeUranium 238- neutrons: 146- atomic mass: 238,050 788 247 ± 0,000 002 044- half life: 4,468.109 years- concentration in natural uranium: 99,2742 %- 238U is a fertile isotopeUranium 234not important
Name one type of nuclear reactor?
CANDU, a reactor type designed in Canada which uses heavy water as the primary coolant.
What is the input energy of nuclear fission reactor?
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.
Does a critical mass of uranium require enriched uranium?
No. Heavy Water moderated reactors like the CANDU type can go critical and run on natural (0.72%) Uranium just fine.
