The U-235 and U-238 masses in natural uranium are split between enriched and depleted streams as a result of an enrichment process. If the input masses and output enrichments are specified, mass conservation determines the maximum (i.e. zero-loss) quantity of each isotope in the output streams. Considering a 1 kg input of natural uranium, a 3 wt % U-235 enriched stream, and a 0.3 wt% U-235 depleted stream"
a. Calculate the masses of U-235, U-238, and total U in each of the two output streams.
b. Calculate the fraction of the initial U-235 that ends up in each output stream.
