Investigation of hydrogen-burn damage in the TMI-2 reactor building
Fifteen entries into the TMI-2 reactor building were made in the period between the accident on March 28, 1979 and October 1981. Photographs and video recordings from these entries were made in association with radiation and decontamination surveys. The Fire Science Group of the Hazards Control Department at Lawrence Livermore National Laboratory (LLNL) and EG and G Idaho, Inc. in cooperation with the Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE) conducted a preliminary analysis of existing photographs of thermally damaged materials in the TMI-2 reactor building. From this survey, an attempt was made to define spatial distribution and extent of thermal damage to susceptible reactor building items. Further work was recommended that could increase the accuracy of estimates of hydrogen deflagration intensity for the purpose of estimating hydrogen concentration range in the reactor building just prior to the deflagration. Photographic evidence from the first fifteen reactor building entries was examined and a preliminary pattern of burn and overpressure damage throughout the TMI-2 reactor building was suggested.
