    Abstract: A plurality of permanent magnets are disposed on a movable object with predetermined spacings between them, and a fixed permanent magnet or magnets are disposed at positions spaced apart by a predetermined distance from the detection portion of a waveguide disposed along the movable object. Magnetostrictive ultrasonic waves generated on the waveguide are detected at the positions of these permanent magnets, and the position of the movable object is detected from the number of ultrasonic wave signals and the propagation time.

    Abstract: A nuclear reactor is supplied with feed water through a feed water pump system. A primary steam flow produced from the reactor is controlled by regulating a recirculated flow of feed water. The feed water pump system comprises two main pumps each of 55%-capacity and two auxiliary pumps each of 27.5%-capacity. Normally, the two main pumps are operated. Upon occurrence of abnormal condition of at least one main pump, the auxiliary pumps are started to supply feed water. At that time, the recirculated flow is controlled for a predetermined time to a reduced rate which is smaller as compared with that of the primary steam flow decreased rapidly due to the shutdown of the main pump. Subsequently, the recirculated flow is so controlled that the primary steam flow rate is slightly smaller as compared with the feed water flow which is determined by the available capacity of the pumps.

    Abstract: A multicontroller apparatus has a plurality of control units each including a controller and a diagnostic device for making a diagnosis of the controller. Each diagnostic device includes an apparatus for judging states of other control units by using output signals of diagnostic devices included in the other control units and an apparatus for executing a diagnosis of the associated controller which is a diagnosis object of the diagnostic device when the judging apparatus has judged that one or more other control units are not in the diagnosis state. Owing to the present invention, a necessary number of controllers which are in the controllable state can always be ensured in a multicontroller apparatus. Therefore, control by the multicontroller apparatus is always possible, and it becomes possible to make a diagnosis upon the multicontroller apparatus.
