ABSTRACT:
Segmented stayrod for restricting transverse displacement of a nuclear heat exchanger tube support plate. The stayrod includes a first rod segment interposed between the tubesheet and the first support plate, the first rod segment having an externally threaded riser extending through the hole formed in the first support plate. The stayrod also has a second rod segment interposed between the first support plate and the second support plate, the second rod segment having an internally threaded end portion for threadably engaging the threaded riser of the first rod segment. The second rod segment also has an externally threaded riser extending through the hole formed in the second support plate. An internally threaded fastener threadably engages the riser of the second rod segment for fastening the second rod segment to the second support plate. In this manner, the first support plate is captured between the first rod segment and the second rod segment. Moreover, the second support plate is captured between said second rod segment and the fastener, so that transverse displacement of the first support plate is restricted as the first support plate is captured between the first rod segment and the second rod segment and so that transverse displacement of the second support plate is restricted as the second support plate is captured between the second rod segment and the fastener.
