WebA bismuth phosphate carrier precipitation process is patented for separating plutonium from fission products. Purification of plutonium is accomplished by precipitating bismuth phosphate in the presence of quadrivalent plutonium, thereby carrying plutonium from soluble fission products, and in another step precipitating bismuth phos phate in the … WebFeb 28, 2007 · Three simulations of the bismuth phosphate precipitation process show that less that 1% of the Tc-99, Cs-135/137, Sr-90, I-129 carry down with the Pu product and thus these isotopes should have remained within the metals waste streams that after neutralization were sent to single shell tanks. Conversely, these isotopes should not be …
