Overview
The Sequoyah Nuclear Plant was a proposed commercial nuclear power facility intended to be sited in the state of Tennessee, United States. The project was associated with the Tennessee Valley Authority (TVA), the federally owned corporation that operates most of the region’s electricity generation and distribution infrastructure. The plant was named after Sequoyah (c. 1770 – 1843), the Cherokee scholar who created the Cherokee syllabary.
History
- Planning Phase (1970s‑1980s) – During the 1970s, TVA conducted feasibility studies for additional nuclear capacity to meet anticipated regional electricity demand. The Sequoyah site, located near the Tennessee River in western Tennessee, was identified as a potential location.
- Design Considerations – Preliminary designs called for a press‑licensed water reactor (PWR) employing conventional light‑water technology, consistent with other TVA nuclear projects of the era. Specific reactor supplier and unit capacity were not finalized in publicly released documents.
- Cancellation – By the early 1980s, changing economic conditions, heightened public and environmental scrutiny, and evolving regulatory requirements led TVA to defer and ultimately abandon the Sequoyah project. The plant never progressed beyond the permitting and site‑selection studies, and no construction began.
Site Selection
The proposed location was adjacent to the Tennessee River, a common siting criterion for nuclear facilities due to the availability of abundant cooling water. Detailed environmental impact assessments were not completed before the project was terminated.
Design and Capacity
Publicly available information does not specify the exact power output or the number of reactor units planned for the Sequoyah Nuclear Plant. The design was intended to align with TVA’s standard nuclear plant architecture of the period, which typically involved 1,000–1,200 MW electric (MWe) units.
Current Status
The Sequoyah Nuclear Plant remains a cancelled proposal. The site has not been developed for nuclear use, and no infrastructure associated with the original plans exists. TVA’s current nuclear fleet comprises other facilities such as Browns Ferry, Watts Bar, and Hatch.

Note: While the existence of the Sequoyah Nuclear Plant proposal is documented in TVA planning archives and federal energy records, detailed technical specifications were never publicly released, resulting in limited encyclopedic coverage.
