Description/Abstract:
This document is concerning Building 9418 Uranium Oxide Burial Vault. Until 1960, nonenriched U3- 08 dross produced by the foundry furnaces was stored in drums and transferred to accountability Code 85, warehouse. In 1959, with storage space about to run out, a decision was made to dispose of the over 1000 MT of dross that had accumulated. Most of it apparently went to Bear Creek Burial Ground and ORNL, and the remaining 228 MT, with 192 MT of contained uranium, were buried in a vault southeast of 9201-1. The pit vault is the remaining below-ground portion of Building 9418-3. As the vault was empty and available, it was decided to fill it with U3 08 dross. The drums were emptied into the vault through the manholes during 1960, and when full, the manholes were filled with concrete. Since that time, the vault has been covered with asphalt as part of a driveway. At the time of burial, the material was still considered to be in storage and remained in Code 85. However, in June 1964, it was decided to transfer the material on paper to Code 98, disposal by burial. On September 28, 1983, a radiation survey was made by Environmental Monitoring with a microroentgen meter. Measurements from above the vault varied from 50 to 110 microroentgens, and the background reading in the immediate area was 10-15 microroentgens. Figures of the location of and asphalt cover on the Uranium Oxide Burial Vault are included.
