| ENS 46425 | 16 November 2010 16:00:00 | 10 CFR 40.60(b)(1) | Contamination Outside Boundary Area Due to a Projectile Off Flight Path | The licensee was conducting live fire exercises at the Ford Farms section of the Aberdeen Test Center when a depleted uranium (DU) projectile went off its flight path and struck metal causing the projectile to shatter and become friable. Ford Farms is an indoor hard target facility that is targeted from weapons outside of the facility. The projectile shattered outside of Ford Farms thus the contamination is outside the facility. Initial surveys indicate contamination levels as high as 400 cpm > background. The licensee has roped off the contaminated area and is sampling the air continuously while they formulate a cleanup plan. They estimate cleanup will take approximately two weeks with an additional week required for post-cleanup surveys. The licensee has made notification to the USNRC Region I office. |
