“…There are various methods used to control the nuclear reactions during reactor operation, such as control rods, burnable absorbers and chemical shim. These methods aim to regulate the neutron spectrum inside the nuclear reactor and adjust the reactor reactivity 1 . Various approaches used to control excess reactivity depend on either the hardening of the neutron spectrum or absorbing the thermal neutrons.…”

Summary The control of the reactor energy increases the reactor fuel cycle time. In this work, a new method has been investigated to control the reactor energy instead of traditional methods. SERPENT2 version 2.1.30 was used to investigate the possibility of using Zirconium rods as an energy regulator in the VVER‐1000. Zirconium rods were used as water displacers. The effect of different Zr rod diameter on the infinite multiplication factor (k∞) of the reactor and the fuel concentration at different fuel burnup steps has been analyzed. Larger fuel pitches have been investigated to increase the Zr rod diameter. The main safety parameters such as the void volume reactivity coefficients, the Doppler reactivity coefficients and the Moderator temperature coefficient have been studied at different fuel pitch and different Zr rod diameter. A comparison between the effect of Zr rods and boric acid on the reactor reactivity proved the efficiency of using Zr rods as reactivity regulation.

“…The fresh fuel causes an excess of reactivity at the beginning of life (BOL). It is necessary to manage this reactivity to maintain the reactor criticality for a longer fuel cycle 2 . At present, to regulate the excess reactivity in the PWR, boric acid is diluted in a coolant and burnable absorbers such as gadolinia are used 3 .…”

Summary The traditional methods for controlling reactor excess reactivity are expensive and have defects during reactor operation. By altering the fuel structure and fissile material distribution, this work presents a new technique for managing excess reactivity at the start of the fuel life. MCNPX code edition 2.7 was used to investigate the neutronic characteristics of the suggested blanket‐seed assembly models and compare them with the reference PWR fuel assembly. Instead of U‐238, Th‐232 was suggested as a fertile nuclide. The impact of the proposed models on the infinite multiplication factor, fuel component concentrations, reactor‐grade plutonium, minor actinides, radial flux of thermal neutrons, and the radial distribution of power has been analyzed. The safety parameters, including the control rods worth, Doppler effect, moderator temperature reactivity coefficients, and the effective delayed neutron fraction, have been studied to reach the most optimum fuel structure.
