摘要： The primary coolant pump of a nuclear reactor, which is usually driven electrically, can be accelerated in the event of a line break by the escaping coolant to such an extent that its mechanical strength is in jeopardy due to overspeed. According to the invention, a brake and/or shut-off means, which can be controlled by the pump pressure differential or the pump speed, are associated with the pump. The invention is of interest particularly for pressurized-water reactors.
