What is it like?

Energy is the measure of how much work things can produce. My type of energy that I'm researching is nuclear energy. Nuclear energy is a powerful energy released by changes in the nucleus of an atom. Nuclear energy comes in the forms of uranium, which is a mineral found in ground rocks. It also includes plutonium, which is a radioactive element that is poisonous. The things that relate to nuclear energy are chain reactions, control rods, radioactive decay, decommissioning, half-life, isotopes, moderator, plutonium, radioactivity, reprocessing, repository, and safestore (definitions in VOCABULARY RELATED TO NUCLEAR ENERGY). There are many countries that produce and use nuclear energy include India, Argentina, South Africa, Russia, Canada, U.S., U.K., Czech Republic, Spain, Japan, Germany, South Korea, Hungary, Ukraine, Slovenia, Sweden, Belgium, Slovakia, France, and Lithuania.
