CONSTRUCTION START OF
SALT WASTE PROCESSING FACILITY AT SRS
Department now has a validated cost and schedule from which we can effectively
plan, build and operate this first-of-a-kind facility,” Jeff Allison, Manager
of DOE’s Savannah River Operations Office, said.
“Today’s milestone continues the momentum for waste clean-up at the
Savannah River Site and supports the Department’s highest priority of closing
nuclear waste tanks and reducing risk to the environment.”
validated cost and schedule estimates a total project cost of $900 million and
projected radioactive startup in November 2013. This estimate includes a risk
assessment and management plan that defines project risks and contingencies to
the project cost and schedule.
ensure the utmost security and safety, DOE upgraded the design requirements for
SWPF to include: increasing the
safety classification for the facility and resulting technical requirements;
cost of materials and labor; enhancements to address seismic/structural design
issues and associated construction modifications.
This estimate is the first to be validated by DOE and independent
technical review teams.
November 2005, the Department directed upgraded design requirements for SWPF to
enhance radiological confinement systems and structures to provide additional
assurance of worker safety in the event of an earthquake or other natural
hazards. The SWPF contractor
completed an Enhanced Preliminary Design and DOE commissioned an independent
technical review team to evaluate that estimate. Industry and cost management
experts performed a detailed review of the initial cost estimate and validated
DOE’s approach finding no outstanding technical issues, with all major
findings and/or observations closed or a path forward established.
the approximate 36 million gallons of radioactive wastes stored in SRS tanks, 33
million gallons is liquid and salt cake. The
SWPF will separate key high-activity radionuclides from the low-activity salt
waste, using extraction technology for the separation of cesium and a monosodium
titanate sorption/filtration technology for separation of strontium and
actinides. After separation, the
high-activity salt waste will be vitrified in the Defense Waste Processing
Facility (DWPF) and temporarily stored onsite until disposal in a geologic
repository. The remaining
high-volume/low-activity salt waste will be treated and disposed of at the
Saltstone Disposal Facility. This
dual-track approach reduces the number of DWPF canisters to be filled and the
facility’s associated lifecycle costs.
