Question

Assuming 200 MeV of thermal energy is liberated from each fission event on an average, find the number of events that
should take place every day
3.24 x 1024
3.24 x 1021
3.24 x 1022
3.24 x 1020​

Answer 1

Answer:

Energy released per disintegration =200 MeV= 200×(1.6×10

−13

)J=3.2×10

−11

J

Total Energy required =1 MW= 10

J/s

No. of integrations required =N=

N

=5.188×10−8 moles/s

Mass consumption =nM= 1.22×10

gms/s

Total consumption in a day =1.22×10
