The HELAC-NLO system has recently allowed for the calculation of several processes in proton-proton collisions at next-to-leading order in the strong coupling constant: tTbB, tT+2 jets (and tT+1 jet), tTH* -> tTbB. In principle NLO QCD corrections to any process in the Standard Model can be evaluated. Soon the functionality will be extended to the electroweak corrections as well. We will discuss the algorithms used and the future of HELAC-NLO. Literature (only main algorithms and tools, more will be discussed during the seminar): hep-ph/0002082, hep-ph/0609007, arXiv:0802.1876 [hep-ph], arXiv:0903.4665 [hep-ph], arXiv:0905.0883 [hep-ph]
