GE Hitachi Nuclear Energy and Advanced Reactor Concepts LLC have agreed to collaborate in the development and licensing of an advanced small modular reactor based on Generation IV sodium-cooled reactor technology. The two companies hope to advance an aSMR design for global power generation with initial deployment in Canada, including the pursuit of a preliminary regulatory review by the Canadian Nuclear Safety Commission, based on earlier technology licensing success in the United States. This collaborative commercialization program will also work to confirm projected construction and operating costs and identify a lead-plant owner and operator for the joint aSMR. GEH and ARC Nuclear have each developed advanced reactor designs based on the EBR-II, an integral sodium-cooled fast reactor prototype which was developed by Argonne National Laboratory and operated successfully for more than 30 years at Idaho Falls, Idaho. These two reactor designs — GEH’s PRISM and ARC Nuclear’s ARC-100 — have been focused on different objectives. The ARC-100 is a 100 MWe aSMR designed for efficient and flexible electricity generation, while operating for up to 20 years without the need for refueling. In contrast, PRISM, which is designed to refuel every 12 to 24 months, has primarily been focused on closing the fuel cycle by, among other things, consuming transuranics.
