Sabatino, R A

In combination with a moisture separator reheater for a nuclear steam generating power plant, a reheater is described comprising: a sealed elongated substantially horizontal tubular shell member, a cycle fluid inlet passing through the shell member in predetermined position, mositure separator means positioned within the shell member proximate the bottom portion thereof, heat exchanger means comprising a plurality of elongated metallic U-shaped members disposed substantially within the shell member, a tube sheet member supporing the U-shaped tube members at one end thereof. The improvement consists of: the tube support member means proximate the U-bend portion of the U-shaped tube members each comprising an upper movable tube support member and a lower immovable tube support member, the remainder of the tube support means being immovable, the upper movable tube support member spacing and supporting the top leg portions of the U-shaped tube members, the lower immovable tube support member spacing and supporting the bottom leg portions of the U-shaped tube members, whereby the top leg portions of the U-shaped tube members proximate the U-bend are permitted to move to compensate for any increase in radius in the U-bend portion of the U-shaped tube member due to thermal expansion.
