The basic lattice used in the experiment arranged in 22.5cm square pitch in DCA core. The core consisted of one hundred and twenty-one 28-element l.2% enriched UO $_{2}$ fuel assemblies. In this core, Boron (B $^{10}$ ) concentration in the moderator has been successively changed from 0 to 3.30, 4.89, 6.43 and and 7.51 ppm by liquefying Boric Acid (H $_{3}$ BO $_{3}$ ) into D $_{2}$ O moderator and made the following measurements; (1)Boron reactivity. (2)Control rod reactivity. (3)100% void reactivity and l/2 core 100% void reactivity. (4) Radial and axial neutron flux distribution. Obtained results are shown in Table 13.
