A capacitor discharge system is used to heat a 17 mm long aluminum sample submerged in water in a test chamber. Two types of aluminum samples are used, wire and ribbon. The ribbon geometry provides a 40.1% increase in surface area over the cylindrical wire. Results show that the critical energy threshold for the ribbon, above which a sustained combustion is observed, is about 500 J/g less than that of the wire sample. The increased surface area serves to enhance the degree of chemical reaction between aluminum and water. Experiments are also performed using wire samples in hot water to investigate the effects of coolant subcooling. The critical threshold is not affected significantly when compared to results from experiments in cold water. However, there is an increase in the interaction strength when the energy delivered to the sample is above the threshold of 2250 J/g.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the possibility of rapid physical and chemical molten fuel-water interactions during a core melt accident in noncommercial or experimental reactors, it is important to understand the interactions that might occur if these materials were to contact water. An existing vertical 1-D shock tube facility was improved and a gas sampling device to measure the gaseous hydrogen in the upper chamber of the shock tube was designed and built to study the impact of a water column driven downward by a pressurized gas onto both molten aluminum (6061 alloy) and oxide and silicide depleted nuclear dispersion fuels in aluminum matrices. The experiments were carried out with melt temperatures initially at 750 to 1,000 C and water at room temperature and driving pressures of 0.5 and 1 MPa. Very high transient pressures, in many cases even larger than the thermodynamic critical pressure of the water ([approximately] 20 MPa), were generated due to the interactions between the water and the crucible and its contents. The molten aluminum always reacted chemically with the water but the reaction did not increase consistently with increasing melt temperature. An aluminum ignition occurred when water at room temperature impacted 28.48 grams of molten aluminum at 980.3 C causing transient pressures greater than 69 MPa. No signs of aluminum ignition were observed in any of the experiments with the depleted nuclear dispersion fuels, U[sub 3]O[sub 8]-Al and U[sub 3]Si[sub 2]-Al. The greater was the molten aluminum-water chemical reaction, the finer was the debris recovered for a given set of initial conditions. Larger coolant velocities (larger driving pressures) resulted in more melt fragmentation but did not result in more molten aluminum-water chemical reaction. Decreasing the water temperature also resulted in more melt fragmentation and did not suppress the molten aluminum-water chemical reaction.
