Progress in the Savannah River /sup 238/Pu Fuel Form Program is summarized. Analytical studies of weld quench cracking in DOP-26 iridium alloy-clad vent sets are reported. Cracks that occur in the arc quench region of the girth welds on DOP-26 iridium alloy-clad vent sets (CVS) have been a problem in production of general-purpose heat sources (GPHS) in the Savannah River Plant (SRP) Plutonium Fuel Form (PuFF) Facility. Previous analytical work has shown that alloy grain boundaries in cracks have a characteristic ridge network porosity. Such porosity is thought to weaken the grain boundaries and promote cracking. Efforts are being made to identify the mechanism responsible for producing the ridge network porosity.
