Let's Know Things

This week we talk about radioactive waste, neutrons, and burn while breeding cycles.We also discuss dry casks, radioactive decay, and uranium.Recommended Book: Breakneck by Dan WangTranscriptRadioactive waste, often called nuclear waste, typically falls into one of three categories: low-level waste that contains a small amount of radioactivity that will last a very short time—this is stuff like clothes or tools or rags that have been contaminated—intermediate-level waste, which has been contaminated enough that it requires shielding, and high-level waste, which is very radioactive material that creates a bunch of heat because of all the radioactive decay, so it requires both shield and cooling.Some types of radioactive waste, particularly spent fuel of the kind used in nuclear power plants, can be reprocessed, which means separating it into other types of useful products, including another type of mixed nuclear fuel that can be used in lieu of uranium, though generally not economically unless uranium supplies
