The measurement and calculation of neutronic parameters in nuclear research reactors has an importantinfluence on control and safety of the nuclear reactor. The power peaking factors, reactivity coefficientsand kinetic parameters are the most important neutronic parameter for determining the state of thereactor. The position of the control shim safety rods in the core configuration affects these parameters. The main purpose of this work is to use the MTR_PC package to evaluate the effect of the partiallyinsertion of the control rod on the neutronic parameters at the operating core of the Tehran ResearchReactor. The simulation results show that by increasing the insertion of control rods (bank) in the core,the absolute values of power peaking factor, reactivity coefficients and effective delayed neutron fractionincreased and only prompt neutron life time decreased. . In addition, the results show that the changes ofmoderator temperature coefficients value versus the control rods positions are very significant. Theaverage value of moderator temperature coefficients increase about 98% in the range of 0e70% insertionof control rod
