The U.S. Department of Energy (DOE) has tasked MSE Technology Applications, Inc. (MSE) with
evaluating the long-term stability of various commercially available sorbent materials to solidify two
organic surrogate wastestreams (both volatile and nonvolatile), a volatile organic surrogate with a residual
aqueous phase, an aqueous surrogate, and an aqueous surrogate with a residual organic phase. The
Savannah River Site (SRS) Legacy and F-Canyon plutonium/uranium extraction (PUREX) process waste
surrogates constituted the volatile organic surrogates, and various oils constituted the nonvolatile organic
surrogates. The aqueous surrogates included a rainwater surrogate and an aqueous organic surrogate.
MSE also evaluated the PUREX surrogate with a residual aqueous component with and without aqueous-
type sorbent materials. Solidification of the various surrogate wastestreams listed above was performed
from 2004 to 2006 at the MSE Test Facility located in Butte, Montana. This paper summarizes the
comparison of the initial liquid release test (LRT) values with LRT results obtained during subsequent
sampling events in an attempt to understand and define the long-term stability characteristics for the
solidified wastestreams.
INTRODUCTION
The U.S. Department of Energy (DOE) tasked MSE Technology Applications, Inc. (MSE) with
evaluating various commercially available sorbent materials to solidify surrogate wastestreams
representative of the Legacy plutonium/uranium extraction (PUREX) process waste, F-Canyon PUREX
waste, a Rainwater wastestream, an Oils wastestream, and an Aqueous Organic wastestream. MSE also
evaluated a surrogate PUREX wastestream with an aqueous component with and without aqueous-type
sorbent materials. The actual radioactive wastestreams were generated at the Savannah River Site (SRS)
during several different processes.
Solidification of the various surrogate wastestreams listed above was performed from 2004 to 2006 at the
MSE Test Facility located in Butte, Montana. This paper summarizes the comparison of the initial liquid
release test (LRT) values with LRT results obtained during subsequent sampling events in an attempt to
understand and define the long-term stability characteristics for the solidified wastestreams. The paper
also includes surrogate Legacy PUREX LRT testing for four granular clay sorbents that were compared.
The paper covers work completed with fiscal year (FY) 2004 funding through the present and details
information about the surrogate wastestream testing listed below.
" Surrogate Legacy PUREX wasteform LRT testing for 22-liter (L) [5-gallon (gal)] bucket samples
generated in 2004 both with and without ultraviolet (UV) protected overpack drums to determine
the effects of sunlight on the solidified Legacy PUREX surrogate samples.
" Surrogate Rainwater wasteform LRT sample testing at the 22-L (5-gal) bucket scale for samples
generated in 2005.
" Surrogate Oils wasteform LRT sample testing at the 22-L (5-gal) scale for samples generated in
2005.1
