2. Explain the difference between 235U and 238U. Which is more abundant in nature?
3. Explain what happens during the enrichment of uranium.
4. You studied the law of conservation of matter in chapter 3 of the text and the first module of this course. You have now studied the law of mass-energy equivalence in chapter 15 of the text and this fourth module of this course. How do these two laws differ?

12. What is the difference between a nuclear power plant and a nuclear reactor?
Explanation / Answer
SOLUTION:-
It is a reaction between two nucleus.there is fission reaction and fussion reaction.in fission the atom get divded and energy is produced.in fussion reaction nucleus get combined and energy is produced. the energy in nuclear reactions comes from "nuclear binding energy." It is the glue which binds the neutrons and protons in the nucleus together- remember that protons are positively charged and normally repel each other, so it takes the "strong nuclear force" to hold them together. If you very precisely weigh the products of an exothermic nuclear reaction, they are slightly lighter than the reactants. This mass loss is converted to energy according to Einstein's famous E=mc^2. The energy released is equal to the mass lost times the speed of light squared!
