RESRAD-RECYCLE: A computer model for analyzing the radiological doses and risks resulting from the recycling of radioactive scrap metal and the reuse of surface-contaminated material and equipment.

A process for reducing the licensing burden for new products containing depleted uranium.

“…Appendix C of Ranek et al (1997) provides a list and descriptions of computer codes and models that can assist in converting DU concentrations to radiation dose estimates. For example, the MICROSHIELD (Negin and Worku 1992), RESRAD-BUILD (Yu et al 2003a), RESRAD-OFFSITE (Yu 2003b), and RESRAD-RECYCLE (Cheng et al 2000) computer codes can be used to estimate the external pathway doses from DU-containing products; the RADTRAN (Neuhauser and Kanipe 1992) and RISKIND (Yuan et al 1995) computer codes can be used to estimate the risk from transportation.…”

“…In addition, the annual radiation dose to the receptors (i.e., S 1 to S 4 , and M 1 to M 7 ) from the ingestion of radioactive materials D ing can be estimated as [19]…”

“…Here, we report a few models which have been developed to estimate the radiological impacts from the recycling of scrap metals in which numerical models similar to Equations (1) to (4) are used as basic formulas for calculation [18][19][20]. Among these models, RESRAD-RECYCLE, developed by the Argonne National Laboratory as a computation tool to calculate radiation doses and risks resulting from the recycling of radioactive scrap metal, was adopted in this study in order to facilitate numerical calculation [19]. The RESRAD-RECYCLE code has been validated and widely applied to the prediction of radiation doses from the recycling of scrap metals containing radionuclides through a series of processes including cutting, smelting, and fabrication [21,22].…”

“…where the value of TP is the reciprocal of time for processing 1 ton of steel scrap which can be derived from the default exposure time for processing 100 ton of steel scrap as proposed in the RESRAD-RECYCLE model [19]. In addition, the values of f M,P for SG as steel scrap in Equation ( 5) are assumed to be 90% for ingot, 10% for slag, and 1% for dust using the default values in RESRAD-RECYCLE [19]. The elements with low boiling points, such as cesium, typically concentrate in the dust, and the elements that easily oxidize tend to concentrate in the slag [19].…”

The elements with low boiling points, such as cesium, typically concentrate in the dust, and the elements that easily oxidize tend to concentrate in the slag [19]. It is noted that default dose coefficients for inhalation and ingestion (see Equations ( 3) and ( 4)) in RESRAD-RECYCLE, which are based upon Federal Guidance Report No.…”
