Title: Estimated temperatures of organic materials in the TMI-2 reactor building during hydrogen burn

Abstract

Maximum surface temperatures attained by certain materials during the hydrogen burn associated with the March 1979 accident at TMI-2 are estimated, using photographs and material samples from the reactor building. Thermal degradation, melting, and charring noted in the photographs, and the chemical and thermal analyses of polymeric and organic materials indicated an increase in temperature with elevation in the reactor building. The maximum material surface temperatures estimated ranged from 360 to 500/sup 0/F (455 to 533/sup 0/K). Analyses were performed to estimate the damage to electrical cables and insulation. Based on temperatures reached and approximate duration, greater than 90% of cable insulation life remains.
