The invention relates to an arrangement comprising a high-pressure
steam turbine module (1), an intermediate-pressure
steam turbine module (2) and at least one low-pressure
steam turbine module (3), a sealing device (100, 101, 200, 300) positioned on a rotating
turbine Between the shaft (5) and the corresponding housing (10, 20, 30) of each
turbine module, each module comprising a main chamber (1', 2', 3') in which the
turbine is housed, the arrangement comprises: A collection chamber (C1) is positioned in the housing (10) of the
high pressure module (1) in order to collect the vapor leakage leaving said
high pressure module (1) through its sealing means (100, 101) at a pressure greater than
atmospheric pressure. flow (F11); and injection chambers (Ca, Cb) positioned in the housing (30) of the low pressure module (3) and connected to said first collection chamber (C1) by a first circuit (61) such that Steam is conveyed from said first collection chamber (C1) to said injection chambers (Ca, Cb) and then through (F31a, F31b) its sealing devices (300a, 300b) to the main chamber of the low pressure module (3) (3')
