Assessment of risks and costs associated with transportation of US Department of Energy radioactively contaminated carbon steel

Environmental review of options for managing radioactively contaminated carbon steel

“…These steel boxes are used for both transport and disposal of LLW. A B-25-type box has a useable capacity of 90 ft3, weighs 800 lb empty, and has a maximum weight capacity of 8,800 lb' (Chen et al 1996). For all disposal sites, packaging is consistent with current DOE, NRC, and DOT guidelines and regulations for transportation and disposal.…”

“…The SeaLand containers are considerably larger than B-25-type boxes, with a useable capacity of 1,200 ft3, an empty weight of 8,000 Ib, and a maximum loaded weight of 44,000 Ib (Chen et al 1996). These larger containers would be used only to transport RCCS to a processing facility.…”

P2Pro(RSM) : a computerized management tool for implementing DOE's authorized release process for radioactive scrap metals.

“…The packaging wastes are assumed to be placed in standard 55-gallon drums. P2Pro(RSM) estimates the number of drums associated with the packaging wastes on the basis of a loading density of 20 lb/ft3 (Chen et al 1996). If the non-real property undergoes a volume reduction, it is assumed that the property and the wastes associated with volume reduction are placed in B-25 type boxes with a packing density of 45 lb/ft3 (Chen et al 1996).…”

If the property does not undergo volume reduction, the packaging density is decreased to 20 lb/ft3, and the material is assumed to be placed in SeaLand type containers.…”

“…The methodology for estimating the dose (mren-dyr) to the MEI from either processing or using the recycled non-real property is presented in Equations 3.12,3.13, and 3.14: The Transportation Module estimates the costs associated with transporting the nonreal property, secondary wastes from decontamination, as well as packaging wastes and volume reduction wastes. The costs are estimated with the methodology from Chen et al (1996). The number of shipments for each material type is estimated on the basis of the total amount of material, packing density (estimated in the Surveying& Volume Reduction Module), and transportation mode.…”
