Conceptual Physics II, Day 10|HyperPhysics***** Physics 7120||Go Back|How can energy be obtained by nuclear fission? What isotopes are useful for such energy processes? How can energy be obtained by nuclear fusion? What fuels seem to be most practical there? Outline the difficulties which have been encountered with nuclear fission energy production. If fission has problems, why don't we use fusion instead? Given that fusion requires incredibly high temperatures, how do we contain such hot stuff? What is a fast breeder reactor? What is the role of the water which jackets the fuel in U.S. nuclear reactors? What do you mean by "moderation" in this context and why is it necessary? If you were told that you had been accidentally exposed to a radiation dose of 10 millirems, what would that mean to you? Are you doomed? Can you just ignore it? What kinds of radioactive isotopes are most dangerous if released into the environment and why?Why does nuclear fission produce so many radioactive byproducts compared to nuclear fusion? What is meant by "critical mass"? If a nuclear fission reactor has more than a critical mass of uranium-235, does that mean it can explode like a bomb? *Energy from mass|*Fast breeder reactor*Meet the milliremConceptual Physics I, Day 12|HyperPhysics*****Physics 7120||Go Back|
