uranium 235

Because uranium-235 is quite rare, making up less than 1% of natural uranium, it has to be enriched until the fuel contains 2-3%.

To make an atomic bomb we have to use uranium 235, in which all the atoms are available for fission.

To make an atom bomb we have to use uranium 235, in which all the atoms are available FOR fission.

To make fuel for electricity-generating reactors, uranium is enriched to less than 5 percent of the isotope U-235.

And the energy density of uranium 235 in terms of thousand times the energy density of coal.

a uranium isotope with mass number 235; capable of sustaining chain reactions.

Nuclear power stations use nuclear fission to generate energy by the reaction of uranium-235 inside a nuclear reactor.

So you put in more fuel, more uranium 235, a higher enrichment and you need to balance that excess reactivity in a number of ways.

Current light water reactors make relatively inefficient use of nuclear fuel, fissioning only the very rare uranium-235 isotope.

An atomic bomb uses conventional explosives to slam together two lumps of fissionable material, usually uranium-235 or plutonium-239.

Uranium 235 -- the fuel inside a nuclear reactor -- undergoes nuclear fission.

The neutrons which are produced will bombard more uranium -235nuclei. This will produce more neutrons and more nuclear energy is released.

The fission of uranium -235 is more likely to occur with slow neutrons than with fast neutrons.

This is called a Fission Neutron Energy Spectrum based on the thermal fissioning of uranium 235.

In atomic bombs, uranium is enriched much more than fuel, to about 85% uranium-235.

Enriched uranium fuel that has a higher proportion of uranium -235 is used in the production of nuclear energy.

Nuclear fission can only occur in some types of heavy and unstable nuclei such as in the uranium -235 and plutonium -239.

Uranium-235 is the fuel for nuclear power stations. It contains 92 protons and 143 neutrons.

When you split a uranium 235 atom you will create what we call fission fragments.
