Project Overview

The SMR-300 is an advanced, passively safe, pressurized light water nuclear power plant with 300 MW(e) rated net electric output. The SMR-300 is designed with forced circulation utilizing two cold legs each with a vertically mounted reactor coolant pump, two hot legs, and a single once-through steam generator (OTSG) with an integral pressurizer stacked on top of the OTSG. The use of reactor coolant pumps during normal operation is necessary to produce the rated power; however, the design utilizes passive, gravity driven safety systems that do not rely on pumps, external water, external power, or operator action. The annular reservoir, the large body of water situated between the containment structure and containment enclosure structure, serves as the SMR‑300 ultimate heat sink.

Pre-Application Documents for the SMR-300 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 its initial design, SMR-160, and its uprated design, SMR-300.
