Thermal stress analysis of metal basemat concept
Conference
·
OSTI ID:5655928
An analysis has been made of a proposed General Electric Company metal basemat concept employing the finite element program STRAW. The basemat is a cost low-carbon steel circular plate which is integral with a poured cavity wall. The integral basemat and cavity wall provides a barrier for core debris accommodation. A thermo-mechanical stress analysis of the unit was performed for several different thermal loadings. Integrity of the cavity wall is maintained if a cooling system is employed for the outer surface; if not, creep buckling failure is predicted. 6 refs., 3 figs., 2 tabs.
