Identification to a breached fuel pin in the IEM cell

Novel methods were successfully employed to identify one breached fuel pin in a 217-pin fuel assembly. The assembly was an experiment that had been irradiated at the Fast Flux Test Facility (FFTF), an experimental liquid-metal reactor operated by Westinghouse Hanford Company for the US Dept. of Energy. A fuel assembly known to contain breached fuel pins was removed from the sodium-cooled FFTF reactor in November 1984. Later, this assembly was brought into the FFTF's Interim Examination and Maintenance (IEM) cell to be disassembled and, for the first time ever at FFTF, to identify a breached fuel pin. The synergistic evaluation of the four different verification techniques - visual examination, cladding swipe activity, wash water radiochemistry, and pin weight - provided rapid and positive identification. The capability to perform future detective work of this kind has been conclusively demonstrated.
