Question

why are cadmium rods provided in nuclear reactors?

Answer 1

hey buddy !! here's your answer...

✔️cadmium rods can absorb neutrons without undergoing change in themselves...

✔️this is done because, due to excess neutrons the nuclear reaction becomes uncontrolled and may cause explosion

hope it helps !! ❤️✌️

Answer 2

cadmium rods are provided in nuclear reactors because when

we start nuclear reacter then more energy is requird for

start the reacter ,we can not start nuclear reacter with

less energy , the rod is used specially for stopping

contact of neutron particles with the system.Cadmium has a high thermal neutron absorption cross section (probability). Therefore Cadmium rods will absorb neutrons, making them unavailable to cause fission. There are also other properties that make cadmium a good control rod material. Things like, it's solid and doesn't dissolve in hot water but mostly it's the cross section thing.
