What does nuclear fission mean?

Answer 1

nuclear fission is where, i am going into a lot of detail here i found out in full extent a few days ago, you have U (uranium) 235 (isotope number) and it is floating around in the water around the reactor, the U235 now sucks up a thermal (same speed and temperature) neutron and Uranium explodes. Which releases 3 elements, heat, and 3 neutrons which all cause friction to heat up water. That water is usually 600ºF and is under about 2100lbs psi (pounds square inch) and that water heats up other water which turns turbines. It heats up other water so turbines and those items are not radioactive. Then that water is around 400ºF 900psi and is cooled off by other water under no pressure and that non-radioactive vapor forms clouds and stuff in the sky, the cooling tower near my house gives off 10,000 gallons of water a minute 80,000lbs. In the case of a "meltdown" the control room drops the control rods to suck up neutrons in water. If the Uranium is still causing heat they increase the boric acid % in the water. The acid sucks up neutrons right from uranium and gives no reaction. The tower, usually 2nd tallest on land, contains the reactor and normally can be hit by a Boeing 737 and only have a burn mark. 2.5ft concrete 3 inch steel and some lead.

Hope this answers your question =) I have more info about the Uranium and other things not mentioned.

Answer 2

Not necessarily. It means that atoms break into smaller parts

Answer 3

it means something.
