REPORT NUMBER: DOT/FRA/ORD-90/01
KEYWORDS: thermal response; radiant heat; environment; small scale cask-like test article
ABSTRACT: The report describes the test series conducted to assess the thermal response of a small scale, cask-like test article to three different thermal environments: an 800 deg C, 30-min radiant heat environment; an 870 deg C, 100-min radiant heat environment; and an enclosed engulfing fire environment of approximately 100-min duration. Results indicated that the average total heat input to a cask-like test article was 140 MJ/sq m for an 870 deg C, 100-min radiant heat environment; 88 MJ/sq m for an 800 deg C, 30-min radiant heat environment; and 125 MJ/sq m for enclosed engulfing fire for an approximate 100-min duration. Results are specific to the test article geometry that was tested and are not applicable to real shipping cask geometries.
