(A) The mass of ${ }_{1}^{2} H$ is $2.014102 \ u$. The mass of ${ }_{1}^{1} H$ is $1.007825 \ u$. The mass of ${ }_{2}^{3} He$ is $3.016029 \ u$. The mass defect $\Delta m = (m({ }_{1}^{2} H) + m({ }_{1}^{1} H)) - m({ }_{2}^{3} He)$. $\Delta m = (2.014102 + 1.007825) - 3.016029 = 3.021927 - 3.016029 = 0.005898 \ u$. The energy released $Q = \Delta m \times 931.5 \ MeV/u$. $Q = 0.005898 \times 931.5 \approx 5.49 \ MeV$.

If each fission in a $U^{235}$ nucleus releases $200 \, MeV$, how many fissions must occur per second to produce a power of $1 \, kW$?

Difficult

View Solution

An atomic power nuclear reactor can deliver $300\ MW$. The energy released due to fission of each nucleus of uranium atom $^{238}U$ is $170\ MeV$. The number of uranium atoms fissioned per hour will be:

What is nuclear energy?

Easy

View Solution

$A$ nucleus of mass $M + \Delta m$ at rest decays into two daughter nuclei of equal mass $M/2$. If the speed of light is $c$,the speed of each daughter nucleus is:

Difficult

View Solution

The energy released by the fission of one uranium atom is $200 \text{ MeV}$. The number of fissions per second required to produce $6.4 \text{ W}$ power is $\qquad$ .
