Abstract
A nuclear reactor plant has a containment shell, a secondary shield enclosing the containment shell and defining therewith an annular space therebetween and a double pipe of a live steam or feedwater line passing through the annular space and formed of a pair of inner and outer pipe portions defining an annular space therebetween. A support member supports an end of the double pipe in vicinity of the secondary shield, the support member having a substantially conical outer surface and being formed with an annular recess communicating with and terminating the annular space formed in the double pipe. Also provided are means for supporting the other end of the double pipe in the containment shell while affording longitudinal movement of the other end of the double pipe.
