Tehran Research Reactor

64Cu is a favorable radionuclide in nuclear medicine applications because of its unique characteristics such as three types of decay (electron capture, b
and bþ) and 12.7 h half-life. Production of 64Cu by irradiation natCu and natCuNPs in Tehran Research Reactor was investigated. The characteristics of copper nanoparticles were investigated with SEM, TEM and XRD analysis. The cross section of 63Cu(n,g) 64Cu reaction was done with TALYS-1.8 code.

The main purpose of this work is to use the MTR_PC package to evaluate the effect of the partially insertion of the control rod on the neutronic parameters at the operating core of the Tehran Research Reactor. 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 fraction increased and only prompt neutron life time decreased.

In this paper, three-dimensional neutronic calculations were performed in order to calculate the dependency of CRW on the temperature of fuel and moderator and the moderator void. Calculations were performed using the known MTR_PC computer codes in the core configuration 61 of TRR. The dependency of CRW on the fuel temperature in the range of 20e340
C and the moderator temperature of each control rods were studied.
