PROBLEM TO BE SOLVED: To allow for prevention of radiation leakage by ensuring the boundary function for the environmental temperature rise in a harsh event or over a long term, while enhancing the seismic capacity and the protection performance for fire.SOLUTION: A cable penetration has a sleeve installed to penetrate the boundary of regions of different environment and internally housing a plurality of cables, and a cable module 14 attached to a head plate 12 at one end of this sleeve, and passing the one end side portion of the cable while holding the sealability, and connects the external cables disposed, respectively, in the regions via the cables. The cable consists of a MI cable 13 having high heat resistance, and a shield 17 having a radiation reduction function, in which a through hole 33 for inserting the conductor 21 of the MI cable 13 is formed, is disposed in the cable module 14.SELECTED DRAWING: Figure 2 |
