We describe the development and application of the ab initio No-Core shell Model, in which the effective Hamiltonians are derived microscopically from realistic, high-quality nucleon-nucleon (NN) potentials plus various realistic three-nucleon (NNN) potentials, as a function of the finite harmonic-oscillator (HO) basis space. For presently feasible no-core model spaces, we evaluate the effective Hamiltonians in a cluster approach, which is guaranteed to provide exact results for sufficiently large model spaces and/or sufficiently large clusters. A number of recent applications of the NCSM are given.
