Title: Closure report for CAU Number 430: Buried Depleted Uranium Artillery Round Number 1, Tonopah Test Range

Corrective Action Unit (CAU) 430 consists of the Buried Depleted Uranium (DU) Artillery Round No. 1. This Closure Report presents the information obtained from investigate actions performed to justify the decision for clean closure of CAU 430 through ``No Further Action``. The site was thought to consist of a potentially unexploded W-79 Joint Test Assembly (JTA) test artillery projectile with high explosives (HE) and DU. The DU was substituted for Special Nuclear Materials to prevent a nuclear explosion and yet retain the physical characteristics of uranium for ballistic and other mechanical tests. The projectile was reportedly buried in one pit, approximately 5 to 10 feet (ft) deep. The objectives of the activities were to prepare the site for closure through locating and identifying the projectile, destroying the projectile and any remaining components, collecting soil samples to detect residual contamination resulting from projectile destruction, and finally, remediating residual contamination. This report contains the following five sections. Section 1.0 introduces the CAU and scope of work. Section 2.0 of this report presents the closure activities performed as part of this investigation. Waste disposition is discussed in Section 3.0. Closure investigation results are presented in Section 4.0, and references are presented in Sectionmore » 5.0.« less
