PURPOSE:To decrease transmission loss and to enable monitoring of the component apparatus in a nuclear reactor container through direct viewing by conducting an image fiber to the penetration part and connecting the image fiber via a lens system to multiple picture element image fibers. CONSTITUTION:A penetration part 7 is provided to a nuclear reactor container 1 so as to pass through a partition wall 5 and a concrete shielding body 6 and multiple picture element image fibers 9 extending in the radial direction of the container 1 are supported to supports 10, 10... and are thus disposed thereon. The inside ends of the fibers 9 are connected via a lens coupler 11 to a fiber 4 and the outside ends thereof is connected via the other lens coupler 12 to an image fiber 13. The coupler 11 expands the image and the coupler 12 reduces the image. A TV camera 14 is connected to the outside end of the fiber 13. |
