Uranium-238 is fissionable but not fissile meaning it can't sustain a chain reaction but can be induced to fission. Uranium-235 is fissile and is the fuel required for a nuclear power station to work.

Uranium 238 requires exposure to high energy neutrons to fission
@simper4951 5 жыл бұрын
yeah, I was confused about that, I think what happens when a neutron hits a U-238 atom is that it turns into P-239 (plutonium)

So...is a fart considered fusion or fission? (Assuming all particles behave as ideal gas in your answer) (Marks will be awarded for writing answer clearly and concisely)

Ohhh get a life. Energy isn't a physical thing, only a concept. To say that "kinetic energy is made" is no less correct than saying "an object's kinetic energy increases". The only thing that matters is how it related to the values.

How can fuel rods be used up if there are still uranium left? Isn't it the uranium itself causing the reaction in the rod?
@ScienceShorts 6 жыл бұрын
+Kaishary Islam Because there is not enough uranium left to cause enough fission for a chain reaction.
@wrath8704 5 жыл бұрын
If mass of fissionable material falls below critical mass chain reaction cannot be sustained (critical mass is minimum mass of fissionable material required to start and sustain a chain reaction)
@peterwilde4494 2 жыл бұрын
I guess you don't care anymore but for anyone else reading this... The other reason for fuel rods still containing uranium being 'used up' is that the fission products produced can be good neutron absorbers themselves and this reduces the number of neutrons available for fission. Chemically removing them can make the fuel viable again. It is processes like this that are referred to as fuel reprocessing. An analogy for this might be the 'poisoning' of a catalyst in chemistry.

Here's a new concept, if everything is permitted by fusion of Fire and Darkness, then by reflection of symmetrical magnetic fields there is a quantum leap by De Broglie's wave transformation and Fourier dimension series.
