Abstract
Located all around Sweden there are firing exercise areas with areas containing UXO (Unexploded ordnance) from years of exercise drills. This study aimed to nvestigate the risk when UXO are exposed to wildland fire at one of their locations, namely Skillingaryd’s firing exercise area. The study was conducted with an initial literature study with the purpose to check what had been done before. The literature study found three (3) reports in total, two (2) conducted by branches of the Swedish armed forces and one (1) conducted by the Norwegian defense research
establishment. All three reports draw the conclusion that exposing ammunition to heat leads to detonation. Using two different models, calculations was done to investigate whether a... (More)
Located all around Sweden there are firing exercise areas with areas containing UXO (Unexploded ordnance) from years of exercise drills. This study aimed to nvestigate the risk when UXO are exposed to wildland fire at one of their locations, namely Skillingaryd’s firing exercise area. The study was conducted with an initial literature study with the purpose to check what had been done before. The literature study found three (3) reports in total, two (2) conducted by branches of the Swedish armed forces and one (1) conducted by the Norwegian defense research
establishment. All three reports draw the conclusion that exposing ammunition to heat leads to detonation. Using two different models, calculations was done to investigate whether a wildland fire at Skillingaryd could cause detonation. At ground surface a lumped heat capacity analysis was used. Below ground surface a numerical calculation was set up. A reasonable temperature-time curve was used to simulate the fire derived from further literature research. The calculated results showed without variation that the heat from the fires was not enough to cause detonation. The
primary reason for this was thought to be how to calculations methods handled the explosive inside the ammunition. Since the literature study and the calculated results was inconclusive, the risk of wildland fire exposed UXO cannot be diminished. (Less)
