PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel ( spent nuclear fuel , or irradiated nuclear fuel).
PUREX, the current standard method, is an acronym standing for Plutonium and Uranium Recovery by EXtraction. The PUREX process is a liquid-liquid extraction method used to reprocess spent nuclear fuel, to extract uranium and plutonium, independent of each other, from the fission products. This is the most developed and widely used process in ...
The advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
The tanks are oozing about 960 gallons a year into soil above groundwater that flows toward Columbia River. 2 Hanford tanks are leaking nuclear waste into the ground. Plan to deal with them settled
Two tanks were reportedly leaking 300 US gallons (1,100 L) per year each, while the remaining four tanks were each leaking 15 US gallons (57 L) per year. [ 223 ] [ 224 ] In February 2013, Washington Governor Jay Inslee announced that a tank storing radioactive waste at the site had been leaking liquids on average of 150 to 300 US gallons (570 ...
Compared to the PUREX aqueous process, it is economical in capital cost, and is unsuitable for the production of weapons material, again unlike PUREX which was developed for weapons programs. [citation needed] Pyroprocessing makes metallic fuel the fuel of choice. The two decisions are complementary. [12]
The cooled oxide fuel is chopped up in the Shear Cell and the fuel dissolved in nitric acid. It is chemically conditioned before passing to the chemical separation plant. Pulsed columns (designated HA/HS) are used to initially separate the majority of the uranium and plutonium from the fission products by transferring them into the solvent ...
An investigation found that the gas leak was in the yard line, which is not maintained by Atmos. The gas supplier was therefore not held responsible for the explosion, according to Railroad ...
