Open Question
What is the function of the control rods in a nuclear reactor? What substances are used to construct the control rods? Why are these substances chosen?
(c) What other substances are used as a moderator in nuclear reactor designs?
Complete and balance the nuclear equations for the following fission or fusion reactions:
(a) 21H + 21H → 32He + _
(b) 23992U + 10n¡ → 13351Sb + 9841Nb + _ 10n
The spent fuel elements from a fission reactor are much more intensely radioactive than the original fuel elements. (b) Given that only two or three neutrons are released per fission event and knowing that the nucleus undergoing fission has a neutron-to-proton ratio characteristic of a heavy nucleus, what sorts of decay would you expect to be dominant among the fission products?
