Studies were made on ripple losses of fusion produced alpha particles in a tokamak reactor with a non-circular plasma cross-section by using an orbit-following Monte-Carlo code. A preliminary estimation of ripple loss of alpha particles in VECTOR, a compact tokamak type fusion reactor, with a negative magnetic shear was also made
