Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.
Red: uranium-238, light green: plutonium-239, black: fission products. Intensity of blue color between the tiles indicates neutron density A traveling-wave reactor ( TWR ) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation , in tandem with the burnup of fissile material.
Pulsed columns then purify the plutonium, removing the troublesome fission products that remain. A mixer/settler (1C) is used to transfer (washes) the uranium across to the aqueous phase ready for the next stage. Uranium purification is achieved using three mixer settlers (UP1 - UP3) similar to those in use on the existing Magnox reprocessing ...
At the natural nuclear fission site discovered at the Oklo mine in Gabon, where nuclear fission reactions occurred 1.7 billion years ago, fission products have moved less than three meters. [25] This minimal movement is attributed possibly more to retention within the uraninite crystal structure than to actual insolubility or sorption by moving ...
Nuclear reprocessing is the chemical separation of fission products and actinides from spent nuclear fuel. [1] Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors. [2]
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
PUREX is applied to spent nuclear fuel, which consists primarily of very high atomic-weight (actinoid or "actinide") elements (e.g. uranium, plutonium, americium) along with smaller amounts of material composed of lighter atoms, notably the fission products produced by reactor operation. A simplified plutonium extraction flow chart.
