Device for recovering a cable at the lower part of a pressure vessel in a reactor

Object: To enable reducing operating time required to prepare use of platform used when repairing machineries at the lower part of a pressure vessel and within a pedestal in the reactor, and to decrease unnecessary exposure of radioactivity to operators. Structure: A pulley having a cable holder mechanism is mounted within the pedestal so as to recover the cable between the platform and the wall of pedestal without requiring removal of a cable connector when the platform is used. When in normal operation, the cable remains hung in a space or the like between reinforcements of the platform, and when in working, the cable is stored between the pedestal and the platform rail and is locked by a locking device of the pulley.
