Investigation of a pulsed pneumatic transportation system for spent fuel is briefly described. Testing parameters for air transport included nozzle optimization and transportation range. The range of particles (30 to 40 mm metal chunks) was determined as a function of the nozzle diameter. A 35 mm diameter was determined to be optimal for the receiver volume and initial gas pressure. Experimental results showed that as receiver volume increases, the transportation range increases linearly until a critical volume is reached; at that point, range becomes constant. As initial gas pressure increases, the transportation range curve is displaced upwards. The system gave stable movement of the metal chunks, eliminating plugs in the standard operating regime. 5 refs., 3 figs.
