Assessment of uncertainty in volume of prior molten zone based upon borehole video data: TMI (Three Mile Island)-2 reactor core

Smith, R P

Examinations of video tapes generated by a remote camera inserted into each of the 10 boreholes through the previously melted zone of the Three Mile Island-2 (TMI) reactor core have contributed greatly to our present knowledge of the end state configuration of damaged material in the core. In order to use the volumes of the damaged zones for fission product mass balance calculations, the uncertainty associated with calculations of those volumes must be known. This report documents the method used for evaluating the uncertainty.
