K Basin Sludge Removal
September, Orano FS received a contract extension from CH2M Hill Plateau
Remediation Company (CHPRC) to provide engineering and technical support
to sludge removal, operations, and closure at the K Basins in the 100-K Area of
the Hanford site. For the 100-K Closure Project, we provided support in sand
and garnet filter media removal includes developing tooling to finalize system
removal of sand and garnet filter media, including support services during
development and testing at Maintenance and Storage Facility (MASF). Orano
supported Basin characterization at KW Basin, including concept development
for sampling tools, tool testing, and development of final product for use at the
100-K Basin. We assisted in the development, procurement and testing of
systems and engineering for special cases such as KW Basin debris that cannot
be disposed of without additional actions to treat, size reduce, shield. We
deactivated and demolition of OF 100 K ANCILLARY FACILITIES, providing
documentation required to continue D&D of 100-K sites / ancillary facilities.
Orano supports design and construction of system(s) to place the KE and KW
reactor buildings in interim safe storage as well as facilities and activities
directly managed by or assigned to the 100-K organization, such as MASF.
Hose-in- Hose Transfer Line (HIHTLs) Deployment and Removal
Orano Federal Services provided engineering management of the design, fabrication, qualification, testing, and installation of temporary transfer lines using hose-in-hose technology. The transfer lines are mobile and reusable, more cost-effective than
welded and buried pipe-in-pipe, shielded at-grade design allows for easy installation and allows vehicle and crane access, and has an integral heat tracing and insulation to minimize the rise of plugging. This technology has been deployed on the Hanford
site since 2000 in S, SX, SY, U, BX, BY, AN, and C tank farms.
In the summer of 2020 Orano completed the removal of six of the eight legacy AY-102 HIHTLs that spanned the distance between AY-102 and AP-102. The HIHTLs were commonly used to transfer
highly hazardous and radioactive waste from single-shell tanks to double-shell tanks. The HIHTLs were rinsed and air blown to reduce residual waste that may have been left in after operations, then carefully coiled and then placed into roll-on/roll-off
waste containers for transport and burial.
