In this study, the effects of selecting water/silver nanofluid as both a coolant and a reactivity controllerduring the first operating cycle of a light water nuclear reactor are investigated. To achieve this, coupledneutronicethermo-hydraulic analysis is employed to simulate the reactor core. A detailed VVER1000/446reactor core is modeled in monte carlo code (MCNP), and the model is verified using the porous mediaapproach. Results show that the maximum required level of silver nanoparticles is 1.3 Vol.% at thebeginning of the cycle; this value drops to zero at the end of cycle. Due to substitution of water/boric acidwith water/Ag nanofluid, reactor operation time at maximum power extends to 357.3 days, and theenergy generation increases by about 27.3%. The higher negative coolant temperature coefficient ofreactivity in the presence of nanofluid in comparison with the water/boric acid indicates that the reactoris inherently safer. Considering the safety margins in the presence of the nanofluid, minimum departurefrom nucleate boiling ratio is calculated to be 2.16 (recommendation is 1.75).
