$A$ certain stable nuclide,after absorbing a neutron,emits a $\beta$-particle and the new nuclide splits spontaneously into two $\alpha$-particles. The nuclide is

What percentage of mass is converted into energy during nuclear fission?

If $200 \, MeV$ energy is released in the fission of a single nucleus of ${}_{92}^{235}U$,the number of fissions required per second to produce a power of $1 \, kW$ is:

$A$ $^{235}U$ nuclear reactor generates energy at a rate of $3.70 \times 10^7 \text{ J/s}$. Each fission liberates $185 \text{ MeV}$ of useful energy. If the reactor has to operate for $144 \times 10^4 \text{ s}$, the mass of the fuel needed is (Assume Avogadro's number $= 6 \times 10^{23} \text{ mol}^{-1}$, $1 \text{ eV} = 1.6 \times 10^{-19} \text{ J}$) (in $\text{ kg}$)
