US utility TVA has submitted a notification of intent to the US Nuclear Regulatory Commission (NRC) that it plans to submit construction permit application (CPA) for a BWRX-300 small modular reactor (SMR) unit at its Clinch River nuclear site in Oak Ridge, Tennessee, by June 2025.

The CPA is essentially the blueprint for the plant’s design and safety systems, and the NRC must approve the plans before CPA begins construction.

The BWRX-300 technology is being developed by GE Hitachi Nuclear Energy (GEH).
