Definitions

  • This invention relates in general to alloys suitable for use in the fabrication of control rods for neutronic reactors, and more specifically to silver base alloys suitable for such applications.
  • the alloys of this invention are essentially improvements of an already existing alloy, which is the subject of copending application Ser. No. 688,995, filed October 8, 1957.
  • This alloy is known to have nuclear properties which make it quite suitable for use as a neutronic reactor control rod material.
  • the already know alloy consists essentially of from 0 to percent of cadmium, from 2 to weight percent of indium and from 65 to 85 weight percent silver, and while this alloy has a proven nuclear worth, it lacks structural strength characteristics to an extent sufficient to restrict its use in some applications.
  • An alloy adapted for use as a neutronic reactor control rod material consisting of from 0.5 weight percent to about 1.5 weight percent of a noble metal selected from the group consisting of platinum, ruthenium, rhodium, osmium, and palladium, up to 10 weight percent of cadmium, from 2 weight percent to 20 weight percent indium, the balance being silver.
  • a control rod member for use in neutronic reactors consisting of an alloy falling within the compositions of claim 1.
  • An alloy adapted for use as a neutronic reactor control rod material consisting of about 1 weight percent platinum, about 5 weight percent cadmium, about 15 weight percent indium, the balance being silver.
  • a control rod member for use in neutronic reactors consisting of the alloy of claim 3.
  • An alloy adapted for use as a neutronic reactor controd rod material consisting of about 1 weight percent ruthenium, about 5 weight percent cadmium, about 15 weight percent indium, the balance being silver.
  • a control rod member for use in neutronic reactors consisting of the alloy of claim 5.
  • An alloy adapted for use as a neutronic reactor control rod material consisting of about 1 Weight percent rhodium, about 5 weight percent cadmium, and 15 weight percent indium, the balance being silver.
  • a control rod member for use in neutronic reac tors consisting of the alloy of claim 7.
  • An alloy adapted for use as a neutronic reactor control rod material consisting of about 1 weight percent osmium, about 5 weight percent cadmium, about 15 percent indium, the balance being silver.
  • V 3 10
  • An alloy adapted for use as a neutronie reactor control rod material consisting of about 1 weight percent palladium, about 5 weight percent cadmium, about 15 weight percent indium, the balance being silver.
  • a control rod member for use in neutronic reactors consisting of the alloy of claim 11.
