The heavy water zero power reactor (HWZPR), which is a critical assembly with amaximum power of 100 W, can be used in different lattice pitches. The last change of coreconfiguration was from a lattice pitch of 18e20 cm. Based on regulations, prior to the firstoperation of the reactor, a new core was simulated with MCNP (Monte Carlo N-Particle)-4Cand WIMS (Winfrith Improved Multigroup Scheme)eCITATON codes. To investigate thecriticality of this core, the effective multiplication factor (Keff) versus heavy water level,and the critical water level were calculated. Then, for safety considerations, the reactivityworth of D2O, the reactivity worth of safety and control rods, and temperature reactivitycoefficients for the fuel and the moderator, were calculated. The results show that therelevant criteria in the safety analysis report were satisfied in the new core. Therefore,with the permission of the reactor safety committee, the first criticality operation wasconducted, and important physical parameters were measured experimentally. The resultswere compared with the corresponding values in the original core.
