Disclosed is a technical installation, especially a nuclear power plant, comprising a number of system components that are respectively supported by a number of beams (1), and a number of pressurized conduits. The aim of the invention is to design said technical installation in such a way that secondary damages occurring in the surroundings of pressurized conduits are kept particularly low even if the pressurized conduits rupture. Said aim is achieved by the fact that at least one of the beams (1) is embodied in a segmented manner in an area that is expected to be affected if a pressurized conduit ruptures, adjacent segments (2a, 2b, 2c) preferably being connected to each other via screw connections (4).
