Axial offset control banks are used to maintain desired axial shape in PWRs. They add asymmetric reactivity in axial mode and change the axial offset (tilt). Estimate the approximate change in induced axial tilts (in \%) in two PWR cores of \(3 \mathrm{~m}\) and \(4 \mathrm{~m}\) height when movement of axial banks introduced \(1.0 \mathrm{mk}\) of reactivity in both of them. For both cores, Fermi age, \(\tau=27 \mathrm{~cm}^{2}, \sum_{\mathrm{a}}=0.0701\left(\mathrm{~cm}^{-1}ight)\) and \(\sum_{\mathrm{t}}=0.103\left(\mathrm{~cm}^{-1}ight)\). \(\mathrm{EVS}=\varepsilon\), Flux tilt \(=ho / \varepsilon\).
