certain properties and ratios in the coolant of VVER-1200 power plant on thermal hydraulic
performance. Criticality and thermal hydraulic analysis have been performed by using
MCNP and COBRA-IV/PC code, respectively. The fuel ratio has been selected as 90% ThO
2+ 10% reactor grade (RG)-PuO 2· Al, Cu, Si, and Ag nanoparticles in proportions of 0.01%
and 0.1% by volume have been mixed with reactor coolant water. The effects of adding …
