TVA has had an on-again, off-again relationship with nuclear power.
The Tennessee Valley Authority has spent billions to start construction on power plants, only to shutter them before completion. The utility spends tens of millions each year maintaining the sites.
In Alabama, TVA started work on the Bellefonte nuclear plant and has spent $6 billion on it since 1974. It remains unfinished. To complete the plant, TVA estimates it would need between $7.4 billion and $8.7 billion.
Closer to Nashville, TVA started work on a proposed nuclear power plant in Hartsville. A single cooling tower — 200 feet tall by 200 feet wide — was built before work stopped. TVA now uses the site for storage.
