Nowdays the atomic parity on-conservation (PNC) in finite Fermi systems has a potential to probe a new physics beyond the Standard model. In our paper we systematically apply computational code based on the QED many-body perturbation theory (PT) [1,2] to precise numerical calculation of the PNC effect in heavy atoms with taking into account the relativistic, nuclear, radiative corrections. The key element is in an accurate taking into account the correlation corrections of the PT second and higher orders (dominating classes: Coulomb interaction screening; interaction «particle-hole» ; mass operator iterations), which is based on using the Feynman diagrammatic technique and Green function (GF) method. There are presented the results of the calculating PNC amplitudes for a number of heavy atomic systems (133Cs, 173Yb, 205Tl, etc) with account of the exchange- correlation, Breit, weak e-e interactions, radiative, nuclear (magnetic moment distribution, finite size, neutron "skin") corrections. The nuclear spin-dependent PNC interactions due to nuclear anapole moment (ka contribution), Z- exchange interaction from nucleon axial-vector (AnVe) currents (k2), the combined hf and spin-independent Z exchange interaction from nucleon vector (VnAe) currents (khf) are considered too.
