Abstract

A heat exchanger that transfers heat generated within a nuclear reactor to a secondary coolant has a support system that accommodates thermal expansion and contraction as well as seismic forces through an arrangement of trunnions and trunnion bearings. The trunnions that are secured to the outer edge of the top tube sheet are limited to movement in a longitudinal direction. The bottom tube sheet trunnions confine the heat exchanger to movement in only one transverse direction. Turning movements produced at the trunnions because of these motions are relieved through lubricated rotation blocks in the trunnion bearings.
