Assuming that about `200 MeV` of energy is released per fission of `._(92)U^(235)` nuceli, the mass of `U^(235)` consumed per day in a fission ractor of power `1` megawatt will be approximately .

A

`10^(-2)g`

B

1 g

C

100 g

D

1000 g

Text Solution

Verified by Experts

The correct Answer is:
b
`1 MW = 10^(6) xx 24 xx 60 xx 60 J`
Number of fissions `= (24 xx 6 xx 6 xx 10^(8))/(200 xx 10^(6) xx 1.6 xx 10^(-19)) = 2.7 xx 10^(21)`
Mass of uranium `= 2.7 xx 10^(21) xx 235 xx 1.66 xx 10^(-24) = 1.05 g`
