What is meant by reactor grade materials?
This means that the nuclear material is of a high enough concentration to fissile (allow for a fission chain reaction). This is because Uranium comes naturally as 99.3% U238, which cannot sustain fission, and .7% U235, which is what they want for the fuel. So they have to find away to pull away the U238 and leave the U235. As they concentrate the U235, it becomes concentrated enough so that it can sustain fission (too much U238 bogs down the reaction and will eventually end the fission). When it reaches this point of concentration, it is concidered reactor grade. Different elements have different needed concentrations to reach this level.
When fuel rods in the reactor core of a nuclear power plant melt due to exposure to too much heat it is known as what?
nuclear meltdown .-. '
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 much plutonium is needed to run a reactor?
This depends on the type and power of the reactor; say tens of metric tons for a commercial reactor..
How much coal gives same energy as 1kg of uranium fuel pellets?
I have a figure but this is for 1 kg of Uranium 235, normally reactor fuel is about 4 percent of this isotope, so the amount of coal would be divided by 25 if we are talking about uranium as used in PWR or BWR reactors. Also this figure is for complete use of the U235, whereas for practical reasons of maintaining reactor performance, fuel is unloaded and replaced before it is all used up. So bearing in mind the above, 1 kg of U235 will produce as much energy as 1500 tons of coal. Let's try: 1kg of U235 (3,75%) has 83,14 TJ/kg. 1J=1Ws (3600Ws=1Wh). 1TJ=1000GJ=1 mio MJ 1kg of coal has 6000Wh/kg. I get 3850tons.
How much does a fusion reactor cost?
Nobody knows- they have not yet built a fully working fusion reactor.
How much uranium produces nuclear power?
The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.
How many pounds of coal do you have to burn to equal the potential energy of one pellet of uranium?
# I'm not clear what size pellet you mean. However for Uranium235 (the fissile isotope), if it is fully used up, 1 kg will give as much energy as 1500 tonnes of coal, ie 1,500,000 kg of coal, so that is the ratio, 1,500,000 to 1. Of course uranium as loaded into the reactor is actually about 4 percent U235, the rest U238 which is not fissile, so the U235 is 1/25 of the total weight of uranium, and if you mean the total uranium weight you therefore have to reduce this ratio by 25, and get 60,000 to 1.
How does one use a breeder reactor?
It would be used as a more efficient version of a Nuclear Reactor. While a regular nuclear reactor requires almost a factor of 100 greater in fuel amounts, a Breeder reactor uses much less and produces less waste.
How many years passed from the first controlled nuclear reactoin to the first nuclear meltdown in US history?
I do not know as I don't have full access to INEL (the nuclear reactor development site in Idaho) records, perhaps a good idea for a FOIA request, the first meltdown would almost certainly have occurred in one of their test reactors long before any commercial reactor. I do know that the core of EBR-I (the first US breeder/power reactor prototype) was damaged in a meltdown on November 29, 1955; it was repaired and finally deactivated in 1964. This reactor has been decontaminated and is open for public tours (docent guided and self guided). I have been there 3 times (the first before decontamination of the floors were complete). I very much suspect they had at least one test reactor deliberately designed to thermally damage or even melt its core to study the effects.
Can you make a real ark reactor?
An Ark reactor as currently describe in comic is very much like a Nuclear Fuel Cell. Possibly convert energy from Nuclear reaction to power. Possibly a plasma nuclear fusion reactor. I believe in the future it could be made. See the link and compare the similarity of fusion reactor and Ark reactor.
How does a meltdown occur?
A meltdown occurs in a nuclear reactor when the core overheats and the fuel rods are damaged, releasing radioactive material. This can happen due to a loss of coolant, causing the fuel rods to become exposed and overheat. If not controlled, this can lead to a breach of the reactor containment and a release of radiation into the environment.
