Question:

How are rods in a nuclear reactor changed?

This is just out of curiosity.but I wonderAnyone know how it's done? The b/f and I were discussing random things and one of us brought up the catastrophe in Japan (Whatever you believe in, keep them in your thoughts and/or prayers, please.) Anyway.he came up with this quot;Before nuclear fission, maybe th rods themselves aren't that radioactive.quot; It's an interesting theoryI, personally.don't care much for nuclear energySo I also wanted to ask.what are some alternatives that appeal to you? Wind is one of my favorites

Answer:

They are made of extremely thin real gold and silverThere is no nutritional value as the serving size is in miligramsIt is strictly for decoration and conversation valueBert

The fuel rods begin as uranium oxide, a ceramic materialLeft on its own, uranium decays very slowly, emitting a low level of radiationHowever, when the fuel rods are assembled in a reactor, they are bombarded with slow (thermal) neutrons, which cause the uranium nuclei to split in halfWhat is left are two smaller nuclei (krypton and barium, for example) which decay much more rapidly than uranium, and are therefore more radioactiveEven when the fission reaction is halted, the fission products (the smaller nuclei) continue to emit large amounts of radiation, and generate large amounts of heat, for many weeksThat's what Japan's dealing with now.
