A current development-status of an automatic calculation system for a Feynman amplitude, GRACE, is reported especially for NLO-QCD processes.
For the tree-level calculation, the event generators for the QCD processes up to 7 final-state particles have been developed. For electro-weak processes, electron-positron scattering at an one-loop correction up to 4-body final state are already obtained using a GRACE system.
New developments of the GRACE system for the NLO-QCD processes are under construction. With the dimensional regularization, simple formulas of a loop integral for zero-, one- and two-off-shell external particle is obtained so far.
