【 摘 要 】

This report details the chemical analysis results for the characterization of the May 19, 2010 inadvertent transfer from the Saltstone Production Facility (SPF) to the Saltstone Disposal Facility (SDF). On May 19, 2010, the Saltstone Processing Facility (SPF) inadvertently transferred approximately 1800 gallons of untreated low-level salt solution from the salt feed tank (SFT) to Cell F of Vault 4. The transfer was identified and during safe configuration shutdown, approximately 70 gallons of SFT material was left in the Saltstone hopper. After the shutdown, the material in the hopper was undisturbed, while the SFT has received approximately 1400 gallons of drain water from the Vault 4 bleed system. The drain water path from Vault 4 to the SFT does not include the hopper (Figure 1); therefore it was determined that the material remaining in the hopper was the most representative sample of the salt solution transferred to the vault. To complete item No.5 of Reference 1, Savannah River National Laboratory (SRNL) was asked to analyze the liquid sample retrieved from the hopper for pH, and metals identified by the Resource Conservation and Recovery Act (RCRA). SRNL prepared a report to complete item No.5 and determine the hazardous nature of the transfer. Waste Solidification Engineering then instructed SRNL to provide a more detailed analysis of the slurried sample to assist in the determination of the portion of Tank 50 waste in the hopper sample.
