The fission properties of 94239Pu are very similar to those of 92235U. The average energy released per fission is 180 MeV. How much energy, in MeV, is released if all the atoms in 1 kg of pure 94239Pu undergo fission?
Solution: Number of atoms in 1 kg of pure Pu=2396.023×1023×1000=2.52×1024
As average energy released in fission is 180MeV, the total energy released is
