TRUEX/SREX demonstration. Innovative technology summary report

PDF Version Also Available for Download.

Description

The tank waste at the Idaho National engineering and Environmental Laboratory (INEEL) must be removed from the tanks by 2012. Transuranic Extraction (TRUEX) and Strontium Extraction (SREX) are the preferred processes for treating INEEL tank waste. The demonstrations for both the TRUEX and SREX processes were carried out separately in the ICPP Remote Analytical Laboratory (RAL) shielded hot cell. A 24-stage bank of 2-cm diameter, centrifugal contactors was fabricated by Argonne National Laboratory. The contractors were modified at the ICPP for remote installation and operation in the RAL hot cell. An overall removal efficiency of 99.79% was obtained for the ... continued below

Description

The tank waste at the Idaho National engineering and Environmental Laboratory (INEEL) must be removed from the tanks by 2012. Transuranic Extraction (TRUEX) and Strontium Extraction (SREX) are the preferred processes for treating INEEL tank waste. The demonstrations for both the TRUEX and SREX processes were carried out separately in the ICPP Remote Analytical Laboratory (RAL) shielded hot cell. A 24-stage bank of 2-cm diameter, centrifugal contactors was fabricated by Argonne National Laboratory. The contractors were modified at the ICPP for remote installation and operation in the RAL hot cell. An overall removal efficiency of 99.79% was obtained for the actinides using TRUEX. An overall removal efficiency of 94% was obtained for the actinides using SREX. The TRUEX and SREX processes will undergo further testing before full-scale processes are built. The experimental results are based on short-term testing (2--3 h). Longer testing times are needed. This report describes the technology, their performance, the application of the technology, costs, regulatory and policy issues, and lessons learned.
