FIGURE 4.3.9. Treatment <strong>of</strong> Combustible <strong>Waste</strong>s and Filters at FRP Remotely Handled<br />

<strong>Waste</strong> Incinerator Facility<br />

The only packaged waste outputs from the example incineration facilties are the drums<br />

containing the pelletized filter media and minor amounts <strong>of</strong> noncombustible waste and crushed<br />

metallic frames from HEPA filters. The estimated quantities- would fill 7.6 55-gallon drums/<br />

GWe-yr from FRP operation and 0.95 55-gallon drums/GWe-yr from MOX-FFP operation. The drums<br />

from the FRP would require remote handling, but those from the MOX-FFP (because the prin-<br />

ciple activity results from alpha radiation) could be contact-handled.<br />

Packaging Without Treatment<br />

The waste packages employed for packaging combustible and compactable wastes without<br />

treatment are steel drums; the larger HEPA filters are packaged in 80-gallon drums, and the<br />

remaining wastes are packaged in 55-gallon drums. The wastes are assumed to be sealed in<br />

plastic bags before they are shipped to the packaging facility. In the packaging facility<br />

they are examined and placed in new drums (if necessary), assayed for fissile material content,<br />

and the lids are tightened to the drums.<br />

The quantities <strong>of</strong> packaged waste are quite large under this option. We estimate<br />

55 80-gallon drums/GWe-yr and 137 55-gallon drums/GWe-yr <strong>of</strong> remotely handled waste and<br />

228 55-gallon drums/GWe-yr <strong>of</strong> contact-handled waste from the FRP. For the MOX-FFP the esti-<br />

mates are 6.6 80-gallon drums/GWe-yr, and 21.5 55-gallon drums/GWe-yr, all <strong>of</strong> which could<br />

be contact-handled.<br />

If the packaging without treatment option is implemented, alternative treatments are<br />

employed for two types <strong>of</strong> combustible waste: ion exchange resins and degraded extractant.<br />

The ion exchange resins are sent to the wet waste and particulate solids immobilizaton<br />

facility, and the degraded extractant is burned in an incineration unit designed specifi-<br />

cally for that purpose.
