2. Calculate the amount of uranium required per year for refueling a Pressurized Water Reactor (PWR) with an installed capacity of 1000 MWe (3000 MWth)

2. Calculate the amount of uranium required per year for refueling a Pressurized Water Reactor (PWR) with an installed capacity of 1000 MWe (3000 MWth) but operating with a capacity factor of 80%. Assume average fuel burnup as 47000 MWD/MTU. 3. If the average 235U enrichment for the fuel defined in the above problem is 4.4% (product) and if the tail/waste from the enrichment process has only 0.2% 235U, calculate the amount of natural uranium feed (235U 0.711%) required in a year to run the above reactor. 4. For the above case calculate the total number of Separative Work Units (SWUs) required. 5. Calculate the total number of Separative Work Units (SWUs) required for obtaining 25 kg of product at 90% 235U enrichment, starting with natural uranium feed (235U 0.711%) and assuming that the tail/waste from the enrichment process has only 0.2% 235U. 6. An enrichment plant has a throughput of 32000 kgU/day and produces 26000 kgU/day as tails. a. What is the enrichment of the product if the feed is natural uranium and the tails are 0.25%? b. Find the number of stages required in a gaseous diffusion process for this obtained enrichment operating with an ideal separation factor ().
