An enrichment plant has a throughput of 32,000 kg U/day and produces 26,000 kg U as tails. What is the enrichment of the product if the feed is natural uranium and the tails are 0.25%

1.10 %

Explanation:

The enrichment of the product can be calculated using the following equation:

  (1)

where W: is waste or tails = 26000, P: is the product = 32000, xp: is the wt. fraction of ²³⁵U in product, xf: is the wt. fraction of ²³⁵U in feed = 0.72% and xw: is the wt. fraction of ²³⁵U in waste or tails = 0.25%.      

By solving equation (1) for xp, we can find the enrichment of the product:

Therefore, the enrichment of the product is 1.10 %.

I hope it helps you!
