  We examine the potential of the future medium-baseline reactor neutrino
oscillation (MBRO) experiments in studying neutrino wave-packet impact. In our
study, we treat neutrinos as wave packets and use the corresponding neutrino
flavor transition probabilities. The delocalization, separation and spreading
of the wave packets lead to decoherence and dispersion effects, which modify
the plane-wave neutrino oscillation pattern, by amounts that depend on the
energy uncertainties in the initial neutrino wave packets. We find that MBRO
experiments could be sensitive to the wave-packet impact, since the baseline is
long enough and also the capability of observing small corrections to the
neutrino oscillations due to excellent detector energy resolution. Besides
studying the constraints on the decoherence parameter, we also examine the
potential wave-packet impacts on the precision of measuring $\theta_{12}$ and
other oscillation parameters in the future medium-baseline reactor neutrino
oscillation experiments. Moreover, we also probe the potential benefits of an
additional detector for studying such exotic neutrino physics.
