The Cleanup Challenge
Total Gallons in Waste Tanks at DOE Sites
Idaho 3 Million
Savannah River 34 Million
Hanford 53 Million
Hanfords 53 million gallons
Hanfords 177 Waste Tanks
11 Million Sludge

• 149 single-shell tanks
• Built from 1943-1964
• Tanks range from 37 to 50 feet tall and are 20
  to 75 feet wide
• 28 double-shell tanks
• Built from 1968-1986
• Tanks are 55 feet tall and 75 feet wide

1.3 Million TRU
42 Million Supernate/Saltcake

Mission Protect the Columbia River

• Hanfords waste tanks are our nations biggest
  environmental problem, threatening the Columbia
  River and the health of the people living
  downstream.
• 67 of Hanfords 177 tanks have leaked
  approximately 1 million gallons of liquid
  radioactive waste
• Some of this waste has reached groundwater
• Oldest waste tanks are WWII vintage newest are
  20 years old
• Eventually radioactive waste will reach the
  Columbia River

The Solution Immobilize the Waste in Glass

• Vitrification offers the best solution
• for immobilizing Hanfords high-level
• radioactive waste and preventing an
• environmental catastrophe.
• Advantages
• Proven technology -- used overseas and at other
  DOE sites
• Sturdy waste form -- impervious to the
  environment
• Disadvantage
• Expensive -- requires large facilities
  constructed to nuclear standards

Build and Operate the Waste Treatment Plant
Storage/Disposal
Tank Waste Management
Vitrification

• Operate tank farms
• Retrieve waste
• Deliver waste to treatment plant

• Pretreat waste
• Process high-level waste to glass
• Process low-activity waste to glass

• Dispose of immobilized low-activity waste
• Store immobilized high-level waste

Project Scope
The WTP is composed of 5 facilities required to
treat and immobilize the Hanford high level tank
waste

• Waste Treatment Plant Facilities
• Pretreatment (PT) Facility
• Low Activity Waste (LAW) Facility
• High Level Waste (HLW) Facility
• Analytical Laboratory
• Balance of Facilities

Special Topics Strategic Fit

• Multi-Facility Acquisition Teams
• Cooperation of facilities to order parts/vessels
  from same fabricators
• By incorporating MFATs in our supply chain, we
  have reduced costs and increased efficiency which
  are highly valued by the customer

12
Special Topics Vendor Managed Inventory

• For Electrical Bulks (Cable, Wire, etc.) Vendor
  is responsible for stocking Inventory

13
Special Topics Use of Information Systems

• Bechtel Procurement System-BPS (company software)
  used in coordinating and scheduling supply chain
  as well as tracking cost throughout the delivery
  and issuance of materials used in construction

Ordering Process

• Online Bidding to Vendors
