Fission and Fusion Processes

How many number of neutrons are released in a fission of U 235?

How do you calculate fission rate?

What percentage of fission is high?

What is the mass of the product of nuclear fission reaction compared to the mass of the original product?

What is fission yield curve?

Two nuclei have mass numbers in the ratio$27:125$. What is the ratio of their nuclear radii? 

State the reason, why heavy water is generally used as a moderator in a nuclear reactor.

During a nuclear fusion reaction

The binding energies per nucleon for a deuteron and an $\alpha$-particle are $1.1 \mathrm{MeV}$ and $7.1 \mathrm{MeV}$ respectively. The energy released in the fusion reaction ${}_1\mathrm{H}^2+{}_1\mathrm{H}^2\to {}_2\mathrm{He}^4$ is $Q$. Then find the value of $\frac{Q}{3}$ in $\mathrm{MeV}$

The average energy released in each fusion reaction is about _____ $\times {10}^{-12} \mathrm{J}$.

(Two decimals should be there in the answer.)

Proton - Proton chain reaction is an example of nuclear _____.

Identify nuclear fusion reaction

Identify nuclear fusion reaction.

If $200 \mathrm{MeV}$ of energy is released in the fission of one nucleus of ${}_{92}{}^{235}\mathrm{U}$, the number of nuclei that must undergo fission to release an energy of $1000 \mathrm{J}$ is

If $200 \mathrm{MeV}$ energy is released in the fission of a single $U^{235}$ nucleus, the number of fissions required per second to produce $1$ kilowatt power shall be (Given $\left.1 \mathrm{eV}=1.6\times {10}^{-19} \mathrm{J}\right):$

What is the power output of ${}_{92}{\mathrm{U}}^{235}$ reactor if it takes$30 \mathrm{days}$to use up $2\mathrm{kg}$ of fuel, and if each fission gives $185 \mathrm{MeV}$ of usable energy?

A slow moving neutron can cause fission in $\mathrm{uranium}-238$.

What is meant by nuclear fission? Why a nuclear fission chain is not self sustained? Explain what is to be done to make a chain reaction sustained?

For the fusion reaction ${}^2\mathrm{H}{+}^2\mathrm{H}{\to }_2^3\mathrm{He}{+}_0^1\mathrm{n}$ masses of deuteron, helium and neutrons are respectively $2.015 \mathrm{u} , 0.017 \mathrm{u}$ and $1.009 \mathrm{u}.$ If $1 \mathrm{kg}$ of deuterium undergoes complete fusion then calculate amount of energy released.
