The neutron-induced reaction cross sections of Zirconium (Zr) are critical for various applications in nuclear reactor design particularly in fuel cladding. The cross sections for 90Zr(n,p)90mY and 90Zr(n,alpha)87mSr reactions have been measured at neutron energy of 14.96 +/- 0.15 MeV using an activation technique. Monoenergetic neutrons were produced via DT fusion reaction and induced gamma activities were measured using a high-resolution High Purity Germanium (HPGe) detector. Furthermore, covariance analysis has been used to estimate the uncertainty and correlation between the current experimental data, accounting for the combined uncertainties from all the parameters involved in the measurement. The measured cross sections of the above-mentioned reactions were also theoretically estimated using EMPIRE 3.2.2 and TALYS 2.0 code from threshold energy to 20 MeV. The measured cross section data was analyzed and compared with the experimental data of previous studies and evaluated libraries (ENDF/B-VIII.0, JEFF-3.3, JENDL-5, TENDL-2023).
