Radionuclide migration using a travel time transport approach and its application in risk analysis

Corrective Action Investigation Plan for the CNTA Subsurface Sites (CAU Number 443), Revision 1

“…The contaminant migration process is described in Dagan et al (1992), Andricevic and Cvetkovic (1996), and Andricevic et al (1994) through the Lagrangian concept of motion following a particle on the Darcy scale. Aquifer heterogeneity is included and represented by the variance of log-hydraulic conductivity, 2 lnK , and the hydraulic conductivity correlation length, .…”

Assessment of hydrologic transport of radionuclides from the Gnome underground nuclear test site, New Mexico

“…A screening tool approach outlined in Daniels et al (1993), Andricevic et al (1994), and Andricevic and Cvetkovic (1996) was used to model radionuclide transport from the Gnome site. The employed modeling approach incorporates real physical phenomena, such as instantaneous and/or slow release from the source, advection, dispersion, sorption, mass transfer, and possible uncertainty in the model parameters.…”

“…The solute flux method is described in detail by Andricevic and Cvetkovic (1996), while important elements of the approach can also be found in Daniels et al (1993) and Andricevic et al (1994). The following summary is derived from these sources, but the reader is directed to these references for a detailed treatment of the method.…”

Exposure assessment of groundwater transport of tritium from the Central Nevada Test Area

“…Instead, a screening tool approach outlined in Daniels et al (1993), Andricevic et al (1994), and Andricevic and Cvetkovic (1995) was used. The employed modeling approach follows the EPA guidelines and incorporates real physical phenomena, such as instantaneous and/or slow release from the source, advection, dispersion, sorption, mass transfer, and possible uncertainty in the model parameters.…”
