METALLURGICAL EXAMINATION OF BORE SAMPLES FROM THE TMI-2 REACTOR CORE
Samples of the borings obtained from the melted core of Three Mile Island unit 2 (TMI-2) reactor have been investigated as part of the collaborative work with the US Dept. of Energy's TMI-2 Accident Evaluation Programme. The samples included fuel rod segments, control rod cladding, melted core rocks and powder debris from various bores into the reactor core. In this study emphasis has been placed on the micro-structure of the phases present in the fuel debris and other samples. Specimen surfaces, or their mounted and polished cross- sections, were examined and analysed by means of optical and electron-optical (SEM/EDAX) techniques. Microprobe analysis (EPMA) was also carried out on selected specimens. Density measurements were performed on the specimens as well as fission product analysis by means of semi-quantitative gamma-spectroscopy and mass spectroscopy of volatile fission products.
