Estimated ^{234}U content in DUThe depletion of ^{234}U can be estimated from the depletion of ^{235}U in the following way (credit to Jiri Kolafa): D(^{234}U) = (1 - 4e)^{n} ® exp(-4ne) for large n D(^{235}U) = (1 - 3e)^{n} ® exp(-3ne) for large n where e is the single stage enrichment efficiency per 1 kg/kmol mass number difference and n is the number of stages. Eliminating the product ne from these two equations (by taking their logarithm and dividing the results) yields D(^{234}U) = D(^{235}U)^{(4/3)} = 0.18 for D(^{235}U) = 0.28 |
