The phenomenon known as tilt represents an asymmetry in the power distribution across the quadrants of the core, where certain regions exhibit a certain imbalance in power compared to others. Although the average power remains unchanged, this imbalance leads to one quarter of the core producing significantly more power than its opposite. Due to its considerable impact on both normal and accidental operations, tilt must be carefully considered in nuclear reactor safety studies. To account for this phenomenon, penalties are applied to specific neutronic parameters, ensuring safety throughout the reactor’s operational lifecycle. Moreover, tilt must be actively limited during reactor operation to prevent significant deviations that could affect core stability and reactor behavior.
