  • SHROUD SUPPORT APPARATUS AND A METHOD OF REFORMING A SHROUD SUPPORT APPARATUS
    Publication number: 20150155061
    Abstract: According to an embodiment, a shroud support apparatus is arranged along the outer periphery of a shroud in a reactor pressure vessel. The shroud support apparatus has: support rods arranged to stand in vertical direction in an annular section formed between an inner surface of the reactor pressure vessel and an outer surface of the shroud, bound to a baffle plate at lower binding sections, and extending upward; upper restraints arranged so as to be bound to upper binding sections of the support rods in order to restrain top end of the shroud; and a load reducing member attached to each support rod so as to reduce the load applied to each support rod when an earthquake takes place.
