Title
(EN) PIPE STAND SEAL STRUCTIRE
(FR) STRUCTURE DE JOINT DE SUPPORT DE TUYAU
(JA) 管台シール構造
Abstract
(EN)
A pipe stand seal structure 1 that seals in an air-tight manner an instrumentation pipe stand 137 that is disposed penetrating the inside and outside of a nuclear reactor and through which a support column 138 is inserted, wherein: the instrumentation pipe stand 137 has a flange part 137a that is provided at the end portion on the external side of the nuclear reactor and that projects to the outside in the radial direction perpendicular to the pipe axis direction; the pipe stand seal structure comprises a blocking member 11 that is provided opposed to the flange part 137a in the pipe axis direction with the support column 138 being inserted in the center thereof, a lower seal member 12 that is provided between the flange part 137a and the blocking member 11, an upper seal member 13 that is provided between the support column 138 and the blocking member 11, a first fastening part 14 that fastens the flange part 137a and the blocking member 11, and a second fastening part 15 that fastens the support column 138 and the blocking member 11; and the blocking member 11 is formed in a disk shape in which the pipe axis direction is the thickness direction.
