MAGNETIC PULSE SWAGING OF APM-UO$sub 2$ FUEL RODS
Technical Report
·
OSTI ID:4636282
Magnetic pulse swaging, a new high energy rate metalworking process, was investigated as a method for eliminating the fuel-cladding annulus in fuel rods made of UO/sub 2/ pellets clad with APM tubing. Three simulated fuel rods were fabricated in which the cladding was swaged through the application of electromagnetic forces. Radiographic inspection of the rods revealed intimate contact between the cladding and the simulated fuel pellets. In one of the fuel rods, containing UO/sub 2/ pellets, the contact was maintained after thermal cycling and heat treatment to 900 deg F. It is believed that tensile hoop stresses are present in the swaged cladding, but the effect of these stresses was not fully investigated. (P.C.H.)
