MOX Actinide Redistribution Enhancement

MOX kernel used to simulate actinide redistribution enhanced by porosity.

Description

Actinide migration, or redistribution, is modeled by thermal diffusion and vapor transport. The description written here is similar to MOXActinideRedistribution , but this class, MOXActinideRedistributionEnhancement, constructs the last term of Equation 6 in Di Marcello et al. (2014), where actinide migration is enhanced by porosity. (1) where is the actinide concentration, is the porosity, is the pore velocity, is the temperature, is the diffusion coefficient, is the universal gas constant, is the effective molar heat of transport, is the pore thickness, is the pore diameter, and is a scaling parameter (default is 1.0). The pore speed, , comes from a calculation performed in MOXPoreVelocity or MOXPoreVelocityVaporPressure. The diffusion coefficient, , is defined by the following equation for Pu and Am: (2)

This class is still under development!

See bison/test/tests/mox_pore_velocity/ for examples of how this class should be used.
