This work investigates the impact of nuclear data on the uncertainty of the Doppler reactivity feedback effect for the MYRRHA fast reactor. Covariance matrices from the JEFF-3.3 and ENDF/B-VIII.0 nuclear data libraries were propagated using a stochastic sampling approach implemented with the SANDY code and the Monte Carlo particle transport code Serpent 2. This technique allowed us to derive an uncertainty bound for the Doppler coefficient that is only marginally affected by the statistical error of the Monte Carlo calculation.
