  We report an implementation of the constrained random phase approximation
(cRPA) method within the projector augmented-wave framework. It allows for the
calculation of the screened interaction in the same Wannier orbitals as our
recent DFT+U and DFT+DMFT implementations. We present calculations of the
dynamical Coulomb screened interaction in uranium dioxide and alpha and gamma
cerium on Wannier functions. We show that a self-consistent calculation of the
static screened interaction in DFT+U together with a consistent Wannier basis
is mandatory for gamma cerium and uranium dioxide. We emphasize that a static
approximation for the screened interaction in alpha cerium is too drastic.
