BACKGROUND
  • Fernald is located 18 miles northwest of
  • downtown Cincinnati, Ohio
  • Fernald operated as a Uranium
  • Processing Facility from 1952 - 1989
  • Materials in Silos are by-product residues
  • from extraction of uranium from ores

REGULATORY BACKGROUND
  • CERCLA Records of Decision (RODs)
  • for all Silos material allow disposal at
  • NTS or appropriately permitted
  • commercial facility
  • Silos waste classified as 11e.(2) byproduct
  • material, statutorily exempt from RCRA
  • Silos waste will be disposed at NTS

SILOS 1 AND 2 RESIDUES
  • The Silos 1 and 2 residues were generated
  • by the extraction of uranium from
  • high-grade uranium ores
  • 8,890 cubic yards of residues are stored
  • in two 80-foot diameter by 30-foot high
  • concrete silos

SILOS 1 AND 2 RESIDUES
  • Waste Characterization
  • Material in Silos is moist, soil-like
  • consistency
  • Radionuclides include Actinium, Lead,
  • Polonium, Radium Thorium

SILOS 1 AND 2 RESIDUES
  • Waste Processing
  • Processing of the Silo 1 and 2 wastes is
  • scheduled to begin October 2004
  • Waste will be stabilized with a mixture of
  • flyash and Portland cement
  • Stabilized waste will be 17-20 residue
  • 80-83 flyash and Portland cement

SILOS 1 AND 2 RESIDUES
  • Waste Packaging
  • 7,000 containers required
  • Loaded into ½-inch thick carbon steel containers
  • Dimensions
  • 6-1/2-foot high
  • 6-foot diameter
  • 4,000-pounds
  • External container volume of 196 cubic feet
  • Container design meets DOT Industrial Package
  • Type 2 (IP-2) requirements
  • Filled containers will have an average weight of
  • 21,000 pounds

SILOS 1 AND 2 RESIDUES
  • Waste Packaging (contd)
  • Anticipated direct radiation dose rates on the
  • outside of the shipping container
  • 75 millirem/hour on contact
  • 9 millirem/hour at two meters from
  • the package

SILOS 1 AND 2 RESIDUES
  • Waste Shipments and Disposal
  • Shipping schedule October 2004 November 2005
  • Two containers per flat bed truck
  • Commercial freight carriers exclusive use trucks
    only
  • Approximately 3,500 shipments
  • 105 trucks per week
  • Disposal at the Department of Energy Nevada Test
    Site
  • Truck access only
  • 2,000 miles one-way from Fernald to NTS
  • 15.2 million miles (round trip) required to
    complete
  • NTS to set up 24 /7 trailer drop and pickup area

SILO 3 RESIDUES
  • Background
  • The Silo 3 residues consist of metallic and
  • non-metallic impurities that remained
    following
  • the extraction of uranium from ore and ore
  • concentrates at Fernald during the mid-1950s
  • 5,088 cubic yards of cold metal oxides are
  • stored in one 80-foot diameter by 30-foot high
  • concrete silo

Graphics 8229.11 4/04

SILO 3 RESIDUES
  • Waste Characterization
  • Relatively dry (3-10 percent moisture by
    weight),
  • powder-like material
  • Silo 3 material has a lower radium content,
  • direct radiation field, and radon-222 emanation
  • rates than the Silos 1 and 2 residues
  • Radionuclide include Actinium, Lead,
  • Protactinium, Radium and Thorium

SILO 3 RESIDUES
  • Waste Processing
  • Processing of the Silo 3 waste is scheduled to
  • begin late May 2004
  • Silo 3 waste will be conditioned to reduce
  • dispersability and mobility
  • Conditioned target waste will be 90 residue
  • and 10 conditioning agent
  • 6 cubic yards per hour
  • 30 packages/day

SILO 3 RESIDUES
  • Waste Packaging
  • 1,910 packages required
  • Waste loaded into triple layer, soft-sided
    packages
  • ( 2 polypropylene with 30 mil neoprene liner)
  • Package design meets DOT Industrial Package
  • Type 2 (IP-2) requirements
  • Filled packages will have an average weight of
  • 4,600 pounds at 84 product fill (96 cubic feet
    )

SILO 3 RESIDUES
  • Waste Packaging (contd)
  • Anticipated direct radiation dose rates on the
  • outside of the shipping container (based on
  • unconditioned material)
  • 7 millirem/hour on contact
  • 3.1 millirem/hour at two meters from
  • the package

SILO 3 RESIDUES
  • Waste Shipments and Disposal
  • Shipping schedule May/June September 2004
  • Seven or eight packages per enclosed trailer or
    ISO

  • Approximately 275 shipments
  • Up to 21 trucks per week
  • Disposal at the Department of Energy Nevada
    Test
  • Site (NTS)
  • Truck access only
  • 2,000 miles one-way from Fernald to NTS
