CABLE MODULE OF ELECTRICAL WIRING PENETRATION PART OF NUCLEAR REACTOR CONTAINMENT VESSEL

摘要

PPROBLEM TO BE SOLVED: To provide a cable module of the electrical wiring penetration part of a nuclear reactor containment vessel capable of eliminating a pressure-leak test in the electrical wire replacement of the nuclear reactor containment vessel and replacing the electrical wire while maintaining the air-tightness. PSOLUTION: The cable module of the electrical wiring penetration part of a nuclear reactor containment vessel includes: a tube shaped body 11 arranged penetrating through the nuclear reactor containment vessel wall 1a as a header plate; a plurality of wire-shaped conductors 40 disposed along the shaft center in the body; a plurality of potting boards 37 for supporting these conductors to the radial direction with intervals; an adhesive seal member 43 disposed surrounding the conductors in the body; and a pair of caps 44 disposed between these seal members with a space part for monitoring the leak and capable of closing the both ends of the body and leading out a plurality of electric wires connected to the conductors, wherein the body 11, the plurality of potting boards 37, the plurality of conductors 40 and the seal member 43 are constituted as an integral body.
