Barbour, J W

The fuel rod support grids developed for use in the LWBR core required a braze alloy that was compatible with AM-350 (the grid material) and that was resistant to aqueous corrosion. Since commercially available alloys normally used to braze stainless steels and nickel-base alloys were found to have poor corrosion resistance, an alternate alloy was developed to meet the LWBR requirements. This alloy, which contains 60 percent nickel, 30 percent chromium, and 10 percent silicon, showed good brazeability properties and excellent corrosion resistance in high temperature water.
