EVALUATION OF ELECTROLESS NICKEL BRAZED TUBE BUNDLES--METALLOGRAPHY REPORT NO. 387
Technical Report
·
OSTI ID:4843502
The metallographic evaluation was made of a bundle of six tubes fabricated using the procedures outlined for fuel bundle fabrication for the Yankee Power Reactor. Bond strengths were determined for three bonds in the two assemblies tested. Both assemblies showed completely cracked joints with continuous networks of Ni-P phase such as is known to cause a weak joint. Accurate fixturing and careful control of phosphorus content of the electroless nickel plating are indicated as means for obtaining substantial improvements in the brazed joints. (B.O.G.)
