How to make nuclear fuel

We offer you a small photo report as produced fuel for nuclear power plants that is with him then and how from it produce energy.




Natural uranium contains only 0, 7% of uranium-235, and 99, 3% of uranium 238. In the majority of reactors is used as fuel enriched uranium, uranium content 235. According to the IAEA's reserves of natural uranium are 4, 3 million tons. This is only explored . Possible - 13 million tons. The reserves of mined uranium - 240 thousand tons.



Further, after the extraction of uranium hexafluoride is converted to uranium. Terrible name for me, anything they do not understand :-) And goes on to say, this is achieved by fluorination of uranium tetrafluoride :-)



the Events ore containing only a few kilograms per tonne of concentrates and fractions. Then processed. Obtained as a result, yellow powder already contains 70% of uranium. Concentration is carried out near the site of production. In our case it is near the town on the border with China.



Getting enriched to 3-5% U-235 is used centrifugal technology: enriched uranium is taken in the center of the rotating at great speed gas centrifuge. At the exit, he has here is a coffee color.



As a result, we have here are tabletochki. That they pressed uranium dioxide for fabrication of fuel elements (TVEL). Each tablet weighing 7 grams gives the energy as much as 570 liters of oil will, or 730 kg of coal. On-for-re-not-be !!!



Tablets are slaughtered in large numbers here in these bars and are available at the plant.



And what happens then we have know about.
