Calculate and compare the energy released by (a) Fusion of 1.0 kg of hydrogen deep within Sun (b) The fission of 1.0 kg of

^{235} U

in a fission reactor

Suppose India had a target of producing by 2020 AD, 200,000 MW of electric power, ten percent of which was to be obtained from nuclear power plants. Suppose we are given that, on an average, the efficiency of utilization (i.e. conversion to electric energy) of thermal energy produced in a reactor was 25%. How much amount of fissionable uranium would our country need per year by 2020? Take the heat energy per fission of

^{235} U

to be about 200 MeV.

Amount of hydrogen,

m = 1 k g = 1000 g

1 mole, i.e.e , 1 g of hydrogen

(_{1}^{1} H)

contains

6.023 \times 1 0^{23}

atoms. Therefore 1000 g of hydrogen contains

6.023 \times 1 0^{23} \times 1000

atoms.

Within the Sun, four

_{1}^{1} H

nuclei combine and form one

_{2}^{4} He

nucleus. In this process

26 M e V

of energy is released. Hence the energy released from fusion of

1 k g

_{1}^{1} H

E_{1} = \frac{6.023 \times 1 0 ^{23} 26 \times 1 0 ^{3}}{4} = 39.149 \times 1 0^{26} M e V

Amount of

_{92}^{235} U

= 1 kg = 1000 g

One mole i.e. 235 g of

_{92}^{235} U

contains

6.023 \times 1 0^{23}

atoms. Therefore 1000 g of

_{92}^{235} U

contains

\frac{6.023 \times 1 0 ^{23} \times 1000}{235}

atoms.

It is known that the amount of energy released in the fission of one atom of

_{92}^{235}

200 M e V

Hence, energy released from the fission of 1 kg of

_{92}^{235}

E_{2} = \frac{6.023 \times 1 0 ^{23} \times 1000 \times 200}{235} = 5.106 \times 1 0^{26} M e V

\frac{E _{1}}{E _{2}} = 7.67 \approx 8

Therefore, the energy released in the fusion of 1 kg of hydrogen is nearly 8 times the energy released in the fission of one kg of uranium.
