Response of a double tube sheet structure to hydraulic pressure transients

Creators

Description

A general procedure was developed to analyze complex tube-sheet structures under dynamic loading conditions. The top shield of a Savannah River Plant production reactor is a stainless steel box structure perforated by tubular conduits. It supports the hanging fuel assemblies and the weight of the reactor superstructure. During normal reactor operation the top shield and the fuel assemblies are submerged in water coolant. For a postualted transient induced by a loss-of-coolant, a loading profile was constructed that considered (1) reduction of bouyancy, (2) rapid pressure changes due to generation and condensation of steam, and (3) vacuum force on one side following condensation. Dynamic responses to such a loading are analytically represented by linear combinations of natural modes that satisfy a fourth-order equation of motion. Localized stress magnification in the tube-sheets of the structure is determined according to the theory of perforated plates
