through FY 2009. The mean total effective dose for every scenario is less than the performance
objective (Table 2).
Table 2 Performance assessment results for the Savannah River Depleted Uranium Trioxide
waste stream averaged over the shallow land burial waste disposed through FY 2009. Chronic
intruder results are weighted with the probability of intrusion. All results are weighted by
probabilistic length of institutional control.

The Savannah River Depleted Uranium Trioxide waste stream is suitable for shallow land burial
at the Area 5 RWMS without conditions. The conclusion is preliminary pending submission of a
final waste profile.
