  • Method for savings in nuclear reactors by using beryllium rods in fuel bundles
    Patent number: 4148687
    Abstract: Nuclear fuels in the form of rod bundle with one or several beryllium rods inserted therein are proposed for use in power reactors positioned to obtain reactivity increase in order to save the D.sub.2 O inventory in a heavy water reactor or to relax the requirement of uranium enrichment if used in light water reactors.

  • Utilization of heavy elements in thermal and epithermal reactors
    Patent number: 4123328
    Abstract: Increases in reactivity can be obtained in thermal and epithermal reactors by utilization of heavy elements in selected locations in the reactors. These increases can result in economic gains, for example, in reduction in the amounts of heavy water needed in heavy water moderated reactors and in reduction of the enrichment needed in light water reactors. A number of examples are provided of advantageous use of the heavy elements in specific reactor embodiments.
