Are you talking about several years? Decades?

Lets first consider all Uranium in Earth's crust, about 65 trillion tons. So given,

  - 65e15 kg = Uranium in Earth's crust
  - 709000 = 709,000 MJ/kg energy density of natural U²
  - 500e12 MJ = 500 million TJ annual global energy usage
  - 92e6 = 65e15 × 709e3 / 500e12

So 92 million years.

Australia has about 1.7e9 kg of reserves at current prices¹. That comes to 2.4 years.
