Will we find Uranium In Space?

Will we find Uranium In Space?

Hello Gang,
Forgive me for the idiosyncratic habit of asking too many
questions. Its one of the quirks in character I have retained since
childhood.

Some people within the space community have called for the development
of nuclear rocketry (NERVA and PROMETHEUS) for the next wave of
exploration of solar system. The question I have is this: Given the
concerns of a possible Challenger style disaster and the possible
consequences if such a disaster involved a nuclear reactor upper stage,
wouldn't it be wise to develop this type of nuclear propulsion on the
Moon instead?

So here is my related question: What are the chances of finding reserves
of Uranium ore on the Moon or asteroids?
