1 27-Aug-26 Please confirm the approximate actual volume of radioactive waste currently requiring disposal, including the estimated volume/fill level of the five (5) 55-gallon drums;

the anticipated number of shipments; and the maximum contact radiation dose rate (mR/hr) for each waste container. The SOW identifies five 55-gallon metal drums (275 gallons total container capacity), but does not state that the drums are full, nor does it specify the number of shipments or maximum contact dose rate.

31-Aug-25 Bidders shall assume the four primary waste drums (1A, 2A, 5A, 6A) are at least ¾ full. External contact radiation dose rates for all containers are at ambient background levels (< 0.1 mR/hr) due to the total decay of short-lived I-125 and the shielding of low-energy beta emitters (H-3, C-14) by the steel drum walls. One consolidated shipment is anticipated, and disposal costs are firm-fixed-price on a per-drum unit basis.
