commercial processes are in drum or batch type mixing. Larger operations are: the ORNL
hydrofracture facility for liquid waste (which is no longer operational), the K-25 Sludge Fixation
Facility, the SRS Saltcrete plant, the Hanford Grout Treatment Facility, PREPP at INEL, and
West Valley's grout facility.
Information is also provided on the use of grouts in the UK, France, Germany, Korea,
Japan, Finland, and Taiwan.
2. NATIONAL
2.1 OAK RIDGE NATIONAL LABORATORY HYDROFRACTURE FACILITY
The concept of fluid waste disposal by hydraulic fracturing was borrowed from the
=. - petroleum industry and developed at ORNL for the disposal of liquid low-level waste (LLLW).
The original pilot plant was modified into an operational facility and was used from 1966 to 1979
to routinely dispose of liquid waste.
In the mid-1970s, a new facility was built that was capable of processing both liquids and
sludges. This facility was completed in 1981 and operated until 1984. The facility is described in
"Conceptual Design Report New Hydrofracture Facility." by H. 0. Weeren et al.
(ORNLT(-4826, July 1975) and in "Design Criteria for New Hydrofracture Facility." Project
No. 78-18-d X-OE-57. For mix design and other details please refer to reports listed in literature
search.
The facility is no longer used to dispose of waste at ORYL.
2.2 SLUDGE FDCATION FACILITY AT THE K-25 SITE
In the mid-1980s, a concrete batch plant surplused from the Clinch River Breeder Reactor
(CRBR) Project was modified for solidifying a variety of pond sludges at the Oak Ridge K-25
Site, previously known as the Oak Ridge Gaseous Diffusion Plant (ORGDP).
