Pre-Application Documents for the SMR-160 Design

The U.S. Nuclear Regulatory Commission (NRC) considers public involvement in, and information about, our activities to be a cornerstone of strong, fair regulation of the nuclear industry. As such, the NRC believes that nuclear regulation should be transacted as openly and candidly as possible to maintain and enhance the public's confidence. Ensuring appropriate openness explicitly recognizes that the public must be informed about, and have a reasonable opportunity to participate meaningfully in, the NRC's regulatory processes. Toward that end, this page provides access to documents and correspondences related to the pre-application activities with SMR, LLC, a Holtec International Company, regarding their SMR-160 design.
