Question

Assume U.S usage of Uranium is 25% of world usage. If the United States were to rely only on its domestic Uranium resources, how long would they last ,assuming a 100 % recovery rate. Show All Work.

Answer 1

Uranium extraction from seawater: Uranium is most often mined from the Earth's crust, but it can also be extracted from seawater, which contains large quantities of uranium (3.3 ppb, or 4.6 trillion kg). Theoretically, that amount would last for 5,700 years using conventional reactors to supply 15 TW of power.
