OSTI ID:6745744
Fission-product release from light-water-reactor-type fuel rods to the coolant was measured during eight fuel damage tests in the Power Burst Facility. On-line gamma spectroscopic measurements of short-lived fission products, and important aspects of fission product behavior observed during the tests, are discussed. The fission-product source terms were found to be very time-dependent, requiring 1 to 3 hours for equilibrium levels to be established. Estimates of the release rate constants generated during certain tests are provided. A comparison is made between calculated and measured release signatures for selected isotopes. Iodine behavior is discussed, and fuel fracturing is identified as a strong release mechanism that may substantially contribute to fission product source terms during light-water-reactor accidents where the core is damaged but the fuel does not melt.
