nucleus into two equal fragments of

_{13}^{28} A l

. Is the fission energetically possible? Argue by working out Q of the process. Given m

= 55.93494 u and m

(_{13}^{28} A l)

= 27.98191 u.

The fission properties of

_{94}^{239} P u

are very similar to those of

_{92}^{235} U

. 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

_{94}^{239} P u

undergo fission?

80%

of the time, that all the energy generated arises from the fission of

Text solutionVerified

Number of atoms in 1 kg of pure Pu=

\frac{6.023 \times 1 0 ^{23}}{239} \times 1000 = 2.52 \times 1 0^{24}

As average energy released in fission is

180 M e V

, the total energy released is

\Rightarrow 2.52 \times 1 0^{24} \times 180 M e V

\Rightarrow 4.53 \times 1 0^{26} M e V
