,- Shipment No. 0488-215 On the " Haste Classification Worksheet" the Co-60 activity of 13.60 uCi/cc l

'

divided by 700 uCi/cc (Class A limit) was reported as 1.94E-4 rather than 1.94E-2. The waste was still properly classified as Class B due to Ni-63, l

Sr-90 and Cs-137 specific activities exceeding the Class A limits. .The l total activity for Co-60 on the Raoicactive Shipment Record (RSR) was L prcperly reporte Shipment No. 0488-216 Nuclide activities were originally calculated by " Rad.un". The hand calculation to verify results calculated 2.89Ci more tlan "Radman" but there were no differences in waste classification or transportation requirements. This sort of discrepancy between hand calculations and

"Radman" is typical and expecte Shipment No. 0888-226 Rounding of volume and mass values resulted in slightly different values for the nuclides listed on the RSR. For example, the Co-60 activity

. propagated through the calculations as 1.38 uCi/cc versus a rounded value of 1.4 uC1/cc. The activity difference in drum 5 due to this rounding was less than 4% and the total shipment activity difference was less than 1%.

There were no differences ir, waste classification or transportation requirement Shipment No. 0888-192 Ag-110m activity was not added to shipment total. The activity of Ag-110m was less than 1% of the tota' activity. By regulation and procedure, this amount of activity does not have to be included in the RSR. There w:#d have been no change in the waste classification or transportatica requirements if it had been adde i Shipment Nr. 0888,276 The Cm-244 activity on the RSR was isted as 2.3 E-1 UCi when it was actually 2.3E-2 uC1. This reduced the total activity of the shipment from 16,779.662 mci to 16,779.452 mC1. This change was much less than 1% of the total activit It did not affect the waste classification or transportation requirements as they were based on the correct value of 2.3E-2 uCi .

Shipment No. 0588-159 The curie value of drum HH-57 was originally calculated by improperly applying contact dose rate conversion factors to a three-foot dose rate reading. Subsequently, the activity of the drum was recalculated using the proper conversion factors. After scaling the non-gamma nuclides, the total drum activity was determined to be 5 Ci versus the 1 Ci reporte The waste class changed from A to B due to higher values of scaled nuclides but this had no effect on burial site criteria as tha drum in question was packed in a HIC with a class C drum. There was no change in transportation requirements as the waste still met LSA requirements.
