In a uranium reactor whose thermal power...

In a uranium reactor whose thermal power is `P=100 MW`, if the average number of neutrons liberated in each nuclear spitting is `2.5`. Each splitting is assumed to release an energy `E=200 MeV`. The number of neutrons generated per unit time is-

A

`4 xx 10^(18) s^(-1)`

B

`8 xx 10^(23) s^(-1)`

C

`8 xx 10^(19) s^(-1)`

D

`(125)/(16) xx 10^(18) s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Number of nuclear splitting per second is
`N = (100 MW)/(200 MeV) = (100)/(200 xx 1.6 xx 10^(-19))s^(-1)`
`therefore` Number of neutrons liberated
`= (100)/(200) xx (1)/(1.6 xx 10^(-19)) xx 2.5 s^(-1) = (125)/(16) xx 10^(18) s^(-1)`

On an average , the number of neutrons and the energy of a neutron released per fission of a uranium atom are respectively

Answer the following questions: Are the equations of nuclear reactions (such as those given in Section 13.7) ‘balanced’ in the sense a chemical equation (e.g., 2H2 + O2→ 2 H2O) is? If not, in what sense are they balanced on both sides? If both the number of protons and the number of neutrons are conserved in each nuclear reaction, in what way is mass converted into energy (or vice-versa) in a nuclear reaction? A general impression exists that mass-energy interconversion takes place only in nuclear reaction and never in chemical reaction. This is strictly speaking, incorrect. Explain.
