[en] Recent trends in the noncommunist countries have included a decrease in projected nuclear power production and an increase in uranium resources. As a result, any serious shortfall in low-cost uranium supply has been averted until after 2025 at the earliest. The need for the breeder reactor has been deferred, and other options for improving uranium utilization efficiency may become important. These options include exploitation of low-grade uranium resources, stripping of uranium from enrichment plant tailings, improved design of light water reactors, and recycle of fuel in thermal reactors. Utimately, breeders will be needed as part of an inexhaustible energy option
