摘要

The invention relates to a centrifugal motor pump for circulating a heat transfer fluid in a nuclear reactor primary circuit. The motor pump comprises a sealed motor unit (12), a hydraulic part (13), and a shaft (17) immersed in the heat transfer fluid, rotated by the sealed motor unit (12), and pumping the heat transfer fluid by means of an impeller (22) of the hydraulic part (13), integral with the shaft (17). The motor unit (12) comprises a dry stator (18) and a submerged rotor (19) mounted integral with the shaft (17). The motor pump also comprises a submerged flywheel (23), mounted integral with the shaft (17), between the rotor (19) of the power unit (12) and the impeller (22) of the hydraulic part (13). , allowing a minimum slowdown time after power failure; and a submerged anti-rollover device configured to mechanically lock the rotation of the shaft (17) in a predetermined direction.
