In light of the renewed interest in uranium mining and production, to meet the world’s energy needs, it is of paramount importance to take advantage of past experiences (including successes, failures and mistakes) gained within the field over the thirty years. This publication includes selected papers presented at the meetings of the UMREG over the past 12 years. The intention is to preserve corporate knowledge within the industry and to assist new entrants to the uranium production business, be they operators or regulators.
