why are boron controls rods used over hafnium in a nuclear reactor?

Good lord, imagine being asked that in the middle of a flirt....blaaank..

@Earliy at least you'd know there was no connection, they were quite possibly a weirdo and you needed to extricate yourself fast, hopefully without hurting their dignity and having them stalk you

Well it's in my course so I'll give it a try.
Basically a control rod is needed to keep the nuclear chain reaction in check so that it doesn't release energy so much, that it becomes too hard to handle or store. Failing to do so results in a nuclear breakdown, a popular example being Chernobyl.

To understand this we must think of a nuclear reaction as a domino effect, of neutron from one atom hitting the nucleus of another atom, which in turn releases the neutron from that atom and so on and so forth.
So it's pretty evident that if we control the neutrons released, controlling a nuclear reaction becomes easy.

Hence we use control rods. These control rods are made of elements which are good at reducing the energy if neutrons and further stopping this domino effect.
