Void reactivities and their 1-st differential coefficients with respect to axial buckling have been measured as a function of void fraction and number of PuO $_{2}$ -UO $_{2}$ fuel clusters progressively substituted for UO $_{2}$ fuel ones, using the pulsed neutron source. Table 1 lists the obtained results. Followings are concluded from this study. (1)Loading of PuO $_{2}$ -UO $_{2}$ fuel clusters increases the negative reactivity contribution to the void effect. (2)Neutron leakage in a core partially loaded with PuO $_{2}$ -UO $_{2}$ fuel clusters does not always produce the negative reactivity contribution to the void effect.
