Abstract: ABSTRACT OF THE DISCLOSURE The mechanical spectral shift reactor provides a method and apparatus  for controlling a nuclear reactor comprising inserting a plurality of reactor coolant dis-placer members into the reactor at the beginning of the core life.  The displacer members reduce the volume  of reactor coolant moderator in the core at the start-up.  As the reactivity of the core declines with fuel depletion, a selected number of displacer members are withdrawn from the core at selected time intervals.  The withdrawal of the displacer member allows reactor coolant water to enter the core which increases core moderation at a time when fuel reactivity is declining.  Thus for a given amount of nuclear fuel the life of the core can be extended or for a given life of a core the uranium fuel requirements can be reduced.

Abstract: ABSTRACT     Disclosed is a flux-feed-forward induction motor controller in which the parameters controlled are motor current and slip frequency.  In known controllers of this type, the controller structure is essentially a network which is an accurate inverse of the transfer function of the induction motor being controlled.  The present invention, however, provides a motor controller circuit which differs from the inverse of the motor circuit.  Briefly, the present invention generates a motor slip frequency value and two current magnitude values representing guadrature components of the motor stator current to be generated.  Closed-loop control of the motor operation is provided by feeding back a signal representative of the motor shaft speed or position to a circuit which compares this signal with an input command to calculate the torque required from the motor.  The feedback signal is separated into high and low frequency components and additional circuitry changes the value of motor torque input parameter in response to detected variations in the high frequency components of the feedback signal.  This causes the motor control circuit to no longer represent the inverse of the motor transfer function network.  The motor controller of the pre-sent invention achieves a significantly increased bandwidth compared to the bandwidth which would be achieved without the additional circuitry.  Where the motor is controlled by a digital control system, the invention allows a major improvement in bandwidth of the motor controller without requiring a high throughput of data processed by the digital portion of the controller.
