The expansion of the nuclear industry to meet anticipated electrical growth requirements is in part dependent on the ability of the domestic uranium industry to expand anticipated uranium demand. This expansion is potentially constrained by many factors, including resource availability, the mounting of an adequate drilling program, availability of competent people, industry financing capability, and the dynamics of expanding an industry from a relatively small base. In the absence of industry success in mounting adequate expansion efforts, customer involvement in risk taking will be required to develop uranium supplies in a timely manner.
