Any one know anything about nuclear fission?

Question

i need help with physics homework. Its about nuclear fission and fusion-


What would a fission power plant look like?

How do nuclear engineers control the amount of fission taking place in a nuclear fission reactor?

What are the conditions for fusion?

Answer 1

Fission is the splitting of atoms of a heavy element, like uranium, into a lighter element, like lead (OK, lead isn't very light, but it is lighter than uranium)

There are many fission plants operating around the world. Homer Simpson works at a fictional fission plant.

Engineers control the amount of fission by sticking control rods into the mass of fuel. The control rods are made of a metal, usually cadmium, that absorbs neutron radiation, which quenches the chain reaction.

Fusion is the combining of atoms of a light element, like hydrogen, to make a heavier atom, like helium (OK helium isn't very heavy, but it is heavier than hydrogen). Very high temperatures are needed and no working reactor has been able to maintain the reaction for more than a fraction of a second.

Answer 2

Nuclear power stations are a reasonably sparkling source of electric powered power, yet this power source is in line with Uranium, that's additionally a constrained source. as nicely, using Nuclear power has right here adverse factors: - Sloppy Nuclear power stations could desire to reason important environmental injury in case of malfunction, see the case of Chernobyl. - some extremist regimes use the pretext of nuclear power so as to get Nuclear bombs, and grow to be a close-by or international adverse factors - Iran working example, or N. Korea. -

Answer 3

larger nuclei when splits into smaller part is known as nuclear fission

Answer 4

Well, all that we're capeable of is (sustained) Fission Currently.....
