FUSION/FISSION QUESTIONS & ANSWERS 1. Why does a chain reaction not occur in uranium mines? There is not enough U-235 present in the ore. It is just 0.7% of the total uranium and it needs to be around 4% to allow chain reactions to occur. 2. What was the function of carbon rods in the atomic reactors? The carbon rods are the “control rods”. They can capture some of the neutrons that are released in the fission process, thus slowing down the reaction if so desired. Removing the rods allow the fission process to run more quickly. 3. What are two possible fates of neutrons in uranium metal? Neutrons may be captured by the control rods (or the circulating water or other non- fissile material) or they may cause a U-235 nucleus to undergo fission. 4. What celebrated equation shows the equivalence of mass and energy? E = mc 2 This tells about the amount of energy released in nuclear processes and how it relates tot the observed mass change of the nuclei. 5. In what form is energy initially released in nuclear fusion? We could call it thermal energy – it’s the kinetic energy of the fast moving nuclei.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
