Japan Atomic Energy Agency
The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities with the Japan Atomic Energy Agency (JAEA) and its corporate partners the IHI Corporation, and the JGC Corporation (hereafter the “JAEA Consortium”) regarding a standard design approval (SDA) application for a Floating Seismic Isolation System (FSIS) paired with a yet named Small Modular Reactor (SMR). The SDA is an NRC staff nuclear plant design approval, issued under 10 CFR Part 52, subpart E. The approval may be for either the final design for the entire reactor facility or the final design of major portions thereof.
