Dynamic response of a lare loop-type LMFBR head closure to HCDA loads

PDF Version Also Available for Download.

Description

An investigation is presented here on the dynamic structural response of the primary vessel's head closure to slug impact loadings generated from a 1000 MJ source term. The reference reactor considered was designed in a loop configuration. The head structure consisted of a deck and a triple rotatable plug assembly. The deck was a large annular structure that was supported along its outer periphery by the vessel flange. The deck provided support to the triple rotatable plug (TRP) assembly along its inner periphery. Two designs were considered for the deck structure: a reference design and an alternate design. The reference ... continued below

Description

An investigation is presented here on the dynamic structural response of the primary vessel's head closure to slug impact loadings generated from a 1000 MJ source term. The reference reactor considered was designed in a loop configuration. The head structure consisted of a deck and a triple rotatable plug assembly. The deck was a large annular structure that was supported along its outer periphery by the vessel flange. The deck provided support to the triple rotatable plug (TRP) assembly along its inner periphery. Two designs were considered for the deck structure: a reference design and an alternate design. The reference deck was designed as a single flat annular plate. For the alternate design, the deck plate was reinforced by adding an extender cyclinder with a flange and flanged webs between the deck-plate and cylinder. A decoupled analysis of this fluid-structure interaction problem was performed. A two-dimensional axisymmetric hydrodynamic computation (reported in a companion paper) was performed to define the head loadings. Then a three-dimensional structural response computation was made to assess the containment capability of the head closure.
