The Battelle Energy Alliance, LLC (BEA) is seeking an Expression of Interest (EOI) from prospective offerors to support construction of the National Reactor Innovation Center (NRIC) Reactor Supplemental Shielding (RSS) at the Idaho National Laboratory (INL). The RSS will be constructed for the Demonstration of Microreactor Experiments (DOME) testbed at the Materials and Fuels Complex (MFC) at the INL. The RSS is a modular high-density concrete structure that will provide radiation shielding from microreactor experiments inside of DOME. The scope of work comprises the fabrication of the all the RSS components, the final layout and field routing of the skid and piping, and the installation of the RSS system. Transportation of the RSS components to MFC and insertion into DOME are also included in this work. Key aspects of the project include: • Reactor Supplemental Shielding (RSS) fabrication of precast block, expansion tank, and heat exchanger & pump skid • RSS piping & I&C routing • RSS component preinstallation fit up • Transportation of all RSS components to MFC • Installation and commissioning inside of DOME
