Atoms And Nuclei Question 224

Question: Energy released in the fission of a single $ _{92}U^{235} $ nucleus is 200 MeV. The fission rate of a $ _{92}U^{235} $ fuelled reactor operating at a power level of 5W is [CBSE PMT 1993]

Options:

A) $ 1.56\times {{10}^{+10}}{{s}^{-1}} $

B) $ 1.56\times {{10}^{+11}}{{s}^{-1}} $

C) $ 1.56\times {{10}^{+16}}{{s}^{-1}} $

D) $ 1.56\times {{10}^{+17}}{{s}^{-1}} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ \frac{Energy}{Fission}=200\ MeV=200\times 10^{6}\times 1.6\times {{10}^{-19}}J $

Fission rate $ =\frac{5}{200\ MeV}=1.56\times 10^{11} $ fission/sec.
