How long does it take to make uranium?
The isotope U-238 has a halflife of 4.5 billion years, roughly the current age of the earth. As the sun is expected to consume the earth in about 6 billion years from now, less than 1.5 halflives will have passed by then. Therefore uranium will remain in the environment as long as earth exists, although at slowly decreasing levels.
