In this study, the effect of Al2O3 with various volume percentages in annular fuels for a typical VVER-1000 core is investigated. CFD is used to simulate the fuel rod. The results of the present study are compared with those of other published studies. Furthermore, the mentioned analytical methods are validated by comparing the final safety analysis report (FSAR). By comparing the results, it was found that the results are in good agreement with other studies. The results show that using annular fuel instead of solid fuel in the core of the reactor will increase the security and efficiency of the nuclear power plant. By increasing the volumetric concentration of nanofluid from 0.1 to 0.2, the rate in decrease of the peak temperature in the central fuel increases from 9% to 13%. Moreover, the clad temperature decreases from 626 K to 620 K (the clad temperature with pure water is 635 K).

“…The trade-off between fuel utilisation and power density was compared across the 5% and 20% enriched BBMSR options considered in this study, in addition to a typical pressurised LWR with a power density of 104 W/cm 3 (Kazimi and Hejzlar, 2006). Figure 11 shows that the 5% enriched BBMSR fuel enables dramatically better fuel utilisation than the LWR cycle, albeit with a nearly 30% reduction of power density.…”

“…Only the main studies on PWRs are highlighted since the focus of this work is on a PWR SMR. (Kazimi et al, 2006) represents a series of studies that focused on uprating the power of existing PWR technology based on a reference 4-loop Westinghouse plant. It was shown that the current 17x17 fuel assemblies have a margin for up to 115 kW/L in power output (currently several 4-loop PWRs in the U.S. operate at 110 kW/L).…”

“…For iPWRs, which is the focus of this work, there are two main studies that utilized a similar methodology as Kazimi et al (2006) to investigate power uprate potential using conventional and advanced fuel configurations. In 2010, the study by Shirvan presented the use of a compact steam generator (CSG) and annular fuel to improve the power density of the IRIS SMR by 50%.…”
