Title: Assessing post-fire combustion of polyurethane

Abstract

In defining hypothetical accident condition thermal test requirements, 10 CFR 71.73(c)(3) states that ``any combustion of materials of construction must be allowed to proceed until it terminates naturally.`` Two examples of extended burning of packages following the regulatory fire are documented. This paper addresses extended burning after cessation of the 30-min, 1475{degrees}F regulatory fire from an analytical perspective with specific application to a package containing polyurethane insulation. Issues include identifying conditions under which materials of construction bum, estimating burn rate, and establishing criteria for cessation of burning. These data and criteria are then applied to determine package temperature profiles using a finite element model. Development of the illustrative problem demonstrates a number of difficulties that are faced when using analytical models to simulate hypothetical thermal accident conditions.
