The enhancement of the fusion reaction rate in high-density two-component plasmas that consist of deuterium (D) and high-{ital Z} material such as carbon (C) or titanium (Ti) has been investigated theoretically. Ion-ion correlation in high-density two-component plasmas is described by a hypernetted-chain (HNC) equation including Coulomb potential of bound electrons. To take into account the effects of bound electrons, we calculate the degree of ionization of atoms consistently with HNC equations by using the Thomas-Fermi model. The results show that the fusion reaction rate of the D-D interaction is enhanced by a factor from 2 to 4 because the strong screening by the surrounding high-{ital Z} ions reduces an effective potential between two colliding deuteriums, and then the degree of ionization of high-{ital Z} materials is found to be important to determine the enhancement factors.
