Kindergarten Number Sense Worksheets. Music Meets Math Worksheets 1-2 - Students will color one-five instruments in a set and practice printing the names of the instruments. This worksheet reinforces instrument recognition, counting to five, vocabulary, and handwriting.
Plutonium (IPA: /ËpluËËtÉÊniÉm/) is a radioactive, metallic chemical element. It has the symbol Pu and the atomic number 94. It is the element used in most modern nuclear weapons. The most significant isotope of plutonium is 239Pu, with a half-life of 24,100 years. It can be made from natural uranium and is fissile.
Thorium needs uranium or plutonium to fission, and when its bombarded with neutrons, it turns into uranium-233, a material that has been used to make bombs.PRO: The waste produced by thorium reactors is a small fraction of the waste produced by traditional nuclear power plants.odcast: Thorium Nuclear Power. On this week's podcast, we looked at the benefits of a particular kind of nuclear reactor, the thorium molten salt reactor. It's a kind of reactor that uses thorium and uranium suspended in liquified solution that generates heat to boil water and turn turbines.
