Compatibility of niobium, titanium, and vanadium metals with LMFBR cladding

PDF Version Also Available for Download.

Description

A series of laboratory capsule annealing experiments were conducted to assess the compatibility of niobium, vanadium, and titanium with 316 stainless steel cladding in the temperature range of 700 to 800/sup 0/C. Niobium, vanadium, and titanium are cantidate oxygen absorber materials for control of oxygen chemistry in LMFBR fuel pins. Capsule examination indicated good compatibility between niobium and 316 stainless steel at 800/sup 0/C. Potential compatibility problems between cladding and vanadium or titanium were indicated at 800/sup 0/C under reducing conditions. In the presence of Pu/sub 0.25/U/sub 0.75/O/sub 1.98/ fuel (..delta..anti G/sub 02/ congruent to -160 kcal/mole) no reaction was ... continued below
