This comparative neutronic study evaluates gadolinia and erbium as effective burnable absorbers in VVER-1200 reactors, suggesting viable alternatives for reactivity control.
Key Points
Gadolinia is widely used in nuclear reactors for its effective neutron capture properties, enhancing reactor performance.
The study compares varying fractions of erbium to standard gadolinia in VVER-1200 assemblies using Monte Carlo simulations.
Results indicate that different erbium variations provide reactivity control similar to 5% gadolinia, albeit with excess reactivity initially.
These findings could improve fuel efficiency and power distribution in VVER-1200 reactors, advancing reactor design.
