Abstract: A nuclear power plant controlling system is provided in which the thermal limit can be brought close to the full limit of operation restrictions by automatic control. The system includes a thermal limit monitor, including a receiver configured to receive a first signal, a prospective time deriving unit configured to derive a prospective time for the first signal to arrive at the full limit, a judging unit configured to judge a remaining time to the prospective time, a compensating unit configured to compensate the first signal based on a second signal, a first transmitter configured to transmit a first instruction to vary a rate factor of the first and second signals by synchronizing the compensation, and a second transmitter configured to transmit a second instruction to hold the first or second signal after arriving at the full limit or at a threshold that is just before the full limit.

Abstract: According to an embodiment, core thermal limit monitoring device is provided with calculating units, and signal input processing units, synchronization processing units and signal output processing units, corresponding to the calculating units. The calculating unit determines if it is necessary to output a signal to the control unit by calculating the thermal state values of the monitoring regions based on a signal representing the state of the core. The synchronization processing unit, if it is necessary to output a signal to the control unit, transmits a signal-output stop signal to the other synchronization processing units, and otherwise, the synchronization processing unit transmits a signal-output stop cancellation signal to the other synchronization processing units. The signal output processing unit, when the synchronization processing unit does not receive a signal stop signal, outputs a signal representing the calculation results of the calculating unit to the control unit.

Abstract: Provide the technique for controlling nuclear power plant in which the thermal limit can be brought close to the full limit of operation restrictions by the automatic control, using the simple information outputted shorter cycle than that of the thermal limit.

Abstract: A snowmobile has a pair of steering skis. Each ski has an elongated primary section that has a bottom surface. The bottom surface extends generally horizontally and warps upward at a forwardly end. A keel section extends along the primary section. The keel section projects downwardly from the primary section. A pair of generally vertical sections extends along the primary section. Each generally vertical section has a generally vertical surface that extends upwardly from a side edge of the bottom surface of the primary section. In one embodiment, a pair of generally horizontal sections extends along the primary section. Each horizontal section has a generally horizontal surface that extends generally horizontally outward from a top end of the generally vertical surface of each generally vertical section.
