Reaction vs Impulse

This article suggests that lower pressures tend to use reaction type turbine impellers.

reaction type turbines are more efficient when it comes to low pressures. As far as the operation and maintenance goes, such turbines usually require less maintenance due to even heating and cooling. The designer usually ensures enough temperatures and gaps between reaction blades to avoid water droplets hitting the blades at high velocities. More importantly in low pressure turbines the steam velocities are not as high as in high pressure turbines, therefore less maintenance is required. Operationally I personally dont think there is a significant difference but an operation engineer will guide u better
