2. SRS DATA SUBMITTAL SUMMARY
The SRS data submittal reported 145 manifested waste shipments, covering 825,319.8 kg, over the
1987-1991 period. In the data submittal, SRS broke the manifests reported into subgroups of containers,
sample composites, waste generator, and waste descriptions. This report calls these subgroupings waste
items. The 145 manifests included 1,399 waste items. SRS categorized all of the waste items as either
clean or likely clean. SRS categorized all waste shipments from within an RCA as likely clean and all
waste shipments from outside an RCA as clean. One hundred and nine of the shipments included clean
waste, and 45 included likely clean wastes. SRS categorized none of the shipments as known radioactive
or likely radioactive.
SRS reported 10 final treatment, storage, and disposal (TSD) facilities that provided treatment or
disposal of the waste. Table 1 contains the final/prime TSD facilities.
2.1 Decision Criteria and Activity Estimates
As part of the original data submittal, SRS reported that bulk decision criteria in effect during the
reporting period were 2 nCi/g. Surface decision criteria were more stringent than limits in DOE Order
5400.5, "Radiation Protection of the Public and the Environment." SRS used these as validation criteria
before shipping waste offsite. Personnel at the generating facility made an earlier determination that their
operation added no radioactivity to the waste before the waste was sent to SRS Waste Management (WM).
For most of the waste shipments, the SRS data submittal included total activity concentrations in
nanocuries per gram from radiological sampling and analyses. TSP used these data to estimate activities
for the waste.
The waste quantities on most manifests were broken down by container, composite number,
generator, and waste description (or waste items). Because of this breakdown, many manifests repeated
more than one waste description. The information submitted by SRS included total activity concentrations
from radiological sampling and analyses for most subgroupings.
To reduce the total entries in the database, TSP combined like waste items and calculated a single
weighted average for each unique waste description on each manifest. However, on some manifests, TSP
found wide variations among the reported total activity concentrations. For these manifests, TSP
calculated more than one weighted average for repeated waste descriptions. Each unique combination of
that waste description and weighted average was reported separately in the HWSDS.
