Title: Reactor module support structure

Patent ·
OSTI ID:1576414

A support structure for attenuating seismic forces in one or more reactor modules housed in a reactor building includes a mounting structure that may be configured to securely connect the support structure to a floor of the reactor building. A receiving area may be sized to receive a lower portion of a reactor module, and the support structure may be configured to at least partially surround the lower portion of the reactor module within the receiving area. The support structure may further include a retention system located near a top surface of the support structure. The retention system may be configured to contact the reactor module during a seismic event, and an upper portion of the reactor module may extend above the retention system without contacting the support structure.
