SPRING CITY, Tenn. (AP) — The Tennessee Valley Authority cost estimate to complete Unit 2 at Watts Bar Nuclear Plant in Spring City, Tenn., has been revised upward to $4.5 billion.
The earlier estimate in 2007 had been $2.5 billion.
In a statement released Thursday, the federal utility blamed the increase on poor previous estimates and that reviews to support the initial estimate were not completed.
