A theory is developed to study shot noise in superconducting (SAS) and hybrid (SAN) junctions with singly occupied Anderson impurity (A) as a weak link. The zero-frequency dc component of the shot noise spectral density is calculated at zero temperature as a function of the bias at different Coulomb repulsion strengths (U), and shows a remarkable structure resulting from combination of electron-electron interaction and Andreev reflections.
