| 摘要 |
<p>The invention relates to a primary pump (100) of a nuclear reactor, comprising: a through shaft (101); a first electric motor (120), referred to as primary motor, powered by a primary power supply network (10), said primary motor allowing the through shaft (101) to be set in motion; a second electric motor (130), referred to as auxiliary motor, powered by a secondary network (20), the auxiliary motor (130) making it possible to set the through shaft (101) in motion in the event of a failure of the primary power supply network (10) or the primary motor (120); said primary pump (100) being characterised in that the primary motor (10) and the auxiliary motor (20) are two electric motors formed by a rotor (122, 132) and a stator (121, 131), the rotors (122, 132) of the two motors (120, 130) being secured to the through shaft (101).</p> |
