  Projective quantum nondemolition (QND) measurement is important for quantum
technologies. Here we propose a method for constructing projective QND
measurement on a nuclear spin via the measurement of an axillary electron spin
in generic electron-nuclear spin systems coupled through weak hyperfine
interaction. The key idea is to apply suitable quantum control on the electron
to construct a weak QND measurement on the nuclear spin and then cascade a
sequence of such measurements into a projective one. We identify a set of
tunable parameters to select the QND observables and control the strength of
the weak QND measurement. We also find that the QND measurement can be
stabilized against realistic experimental control errors. As a demonstration of
our method, we design projective QND measurement on a $^{13}$C nuclear spin
weakly coupled to a nitrogen-vacancy center electron spin in diamond.
