Abstract: An exchange system comprising a plurality of redundant clock supply modules for receiving respective clock signals to maintain synchronization. Each redundant clock supply module includes a phase locked loop coupled to receive a network synchronizing reference signal, for generating a most significant clock of the exchange system synchronized to the network synchronizing reference signal; a clock generator for counting the most significant clock to generate a plurality of system clocks including a least significant clock and a first frame pulse; and a redundancy synchronizer for synchronizing the first frame pulse and a second frame pulse from a counterpart redundancy module to generate a redundancy synchronization signal for establishing synchronization between redundancy modules from the most significant clock to the least significant clock.

Abstract: Disclosed is a method for removing a thermal sleeve from a cold leg of a reactor coolant system, which enables removal of an unintentionally separated thermal sleeve without implementation of a pipe cutting operation, preventing invasion of impurities into pipes and securing reliability in repetitious welding of the pipes. In particular, the method enables a remote operation and an underwater operation using wire ropes, thus being capable of minimizing a negative effect on workers due to radiation exposure.

Abstract: Disclosed is an apparatus for removing a thermal sleeve from a cold leg of a reactor coolant system, which removes an unintentionally separated thermal sleeve without pipe cutting, preventing invasion of impurities into pipes and achieving reliable pipe re-welding. The apparatus includes a sleeve removal tool including a corn head formed at a shaft, a pressure plate below the corn head to maximize hydraulic pressure inside a safety injection pipe, a spring connected to the pressure plate to keep the pressure plate unfolded, and a guide wheel to guide the sleeve removal tool into the safety injection pipe, a horizontal movement carrier including bodies connected to each other by a link, a seating rod for seating of the sleeve removal tool, and moving wheels for movement of the horizontal movement carrier, and a vertical movement carrier including first and second anti-separation bars to prevent separation of the horizontal movement carrier.
