Patent ·
OSTI ID:6057682
A steam generator wrapper barrel/tube support plate connection assembly is described comprising: (a) a generally cylindrical outer shell having a first diameter; (b) a wrapper barrel having a second, relatively smaller diameter so as to fit within the outer shell with an annular space therebetween, and being made of a material having a first coefficient of thermal expansion; (c) a plurality of vertically spaced tube support plates located within the wrapper barrel, each being made of a material having a second, relatively higher coefficient of thermal expansion; and (d) adjustable jacking assembly means positioned between the wrapper barrel and the outer shell, for effecting a preload in the wrapper barrel such that a deformation is caused in the wrapper barrel at the adjustable jacking assembly means.
