This document presents a numerical study of the effects high density nuclear reactions, pycnonuclear on evolution white dwarfs that accrete matter from companion star. Primarily we seek observable properties might be different when include these reactions with varying microphysical assumptions. These assumptions effective nucleon-nucleon interactions, lattice structures and crystal polarization characteristics. Our results indicate that, although find some significant differences in reaction rates, do not result dwarf evolution. Secondarily examine are assumed to happen they happen. In this case, our calculations there can radius, $R$, temperature, $T_{eff}$, at stopping condition use for simulations, $L_{nuc} > 10^{8}\thinspace \rm{L}_{\odot}$, is total rate energy released by fusion greater than $10^{8}$ solar luminosities. Thirdly explore often neglected effect temperature enhancement rates.
