Abstract: A control rod position indication system is for a nuclear reactor with a reactor core and at least one control rod which is movable along a linear path of movement for controlling reactivity of the core. The system includes a permanent magnet mounted on the control rod or a corresponding drive rod, and a number of reed switches arranged around the path of movement in order to be switched by a magnetic field generated by the permanent magnet when passing by. The permanent magnet has a north-south axis whose orientation is constant during movement, and the respective reed switch has a number of reed contacts which are aligned along a longitudinal axis. The longitudinal axis of at least one reed switch is inclined relative to the north-south axis of the permanent magnet, and the angle of inclination has an absolute value within a range from 15 to 65 degrees.

Abstract: A control rod position indication system (2) is for a nuclear reactor (4) with a reactor core (8) and at least one control rod (6) which is movable along a linear path of movement for controlling the reactivity of the reactor core (8). The control rod position indication system (2) includes a permanent magnet (16) mounted on the control rod (6) or a corresponding drive rod (12), and a number of reed switches (20) arranged around the path of movement in order to be switched by a magnetic field generated by the permanent magnet (16) when passing by. The permanent magnet (16) has a north-south axis (18) whose orientation is constant during movement, and the respective reed switch (20) has a number of reed contacts (22) which are aligned along a longitudinal axis (24). The longitudinal axis (24) of at least one of the reed switches (20) is inclined relative to the north-south axis (18) of the permanent magnet (16), and the angle of inclination (W) has an absolute value within a range from 15 to 65 degrees.

Abstract: In one embodiment, the present invention is an anchoring rod that is elongated and tapered, the rod extends from a distal end toward a proximal end, the shape including a palmate side, a dorsal side and lateral sides, is the shape being flared on its palmate side without flaring on its dorsal side and flares on its lateral sides so as to form a flared proximal portion, said flared proximal portion having a substantially trapezoidal cross-section, with a dorsal face larger than the palmate face.

Abstract: After a first start-up, a first appliance performs a self-learning step for generating usage parameters. These parameters are elaborated on subsequent start-ups. When these parameters are optimized, the first appliance transmits them to another appliance which requests them. This second appliance uses the parameters of the first as optimized parameters. In this way, the second appliance limits the duration of the self-learning step and the use of non-optimal parameters. According to a refinement, the optimal parameters are centralized on a server which transmits them to a plurality of second appliances using a transmission network. The present invention also relates to an appliance and a server implementing the method.

Abstract: The present invention discloses a method of servo controlling an electric motor during its start-up, comprising at least one step of measuring the speed after a determined duration counting from the commencement of start-up. During a first start-up, the servo control system determines the deviation between the value of the measured speed and a preset value. During a second start-up, the servo control system modifies at least one duration parameter of the commands applied to the motor as a function of the deviation determined during the first start-up, so as to reduce this deviation in the course of this second step. Advantageously, the start-up comprises three phases making it possible to start the motor while avoiding making it too noisy. The invention also relates to an apparatus implementing the method.
