The present invention relates to a longitudinally divided emergency core cooling (ECC) duct in order to efficiently inject safety water to core of a pressurized light-water nuclear reactor. The ECC duct includes side supports for preventing the flow-induced vibration in the annular downcomer, and has structural stability while thermally expanding and contracting. A longitudinally divided ECC duct for emergency core cooling water injection of a nuclear reactor is provided on the periphery of a core barrel of a nuclear reactor, includes an emergency core cooling water inlet facing a direct vessel injection nozzle, and extends in a longitudinal direction of the core barrel. The longitudinally divided ECC duct is divided into a plurality of longitudinally-divided ducts in the longitudinal direction of the longitudinally divided ECC duct.

A coupling/decoupling assembly of a pipe which can selectively open/close a flow channel of the pipe is provided. In the coupling/decoupling assembly of the pipe, a first valve and a second valve are respectively joined with each end of a first pipe and a second pipe. A first driving axis and a second driving axis are respectively joined with each end of the first valve and the second valve. An outer surface and an inner surface of the first and second valves are formed in a spherical body, and the inner surface of the first valve and the outer surface of the second valve are overlapped with each other to close the flow channel of the pipe, and the inner surface of the first valve and the outer surface of the second valve having an identical radius of a curvature.
