Chiral forces offer a alternative venue for accurate calculations bridg- ing the gap with the underlying theory of QCD. Their predictive power has to be tested in ab initio calculations. The ab initio No- Core Shell Model with Continuum (NCSMC)  is capable of address- ing both structural and reaction properties [2,3] of light-nuclei. This method can accurately describe reaction systems of more than five nu- cleons extending the range of ab initio reaction applications. We have developed the NCSMC formalism for the description of nucleon- and deuteron-nucleus scattering including three-nucleon forces. We will present results for the N-4He and d-4He scattering processes when ac- counting for the chiral two- plus three-nucleon interaction versus the chiral two-nucleon interaction, our progress to describe the α + n + n three-cluster dynamics and initial calculations of the d(t,α)n fusion including the three-nucleon forces within NCSMC. This work paves the way for modeling of light-ion fusion reactions with realistic nuclear forces, that are important for understanding nuclear astrophysics processes.a
