TVA says unit at Watts Bar nuke plant to cost more
The Tennessee Valley Authority said Thursday it will cost up to $2 billion more to complete Unit 2 at Watts Bar Nuclear Plant in Spring City.
The federal utility said the total cost is now up to $4 billion to $4.5 billion. The earlier estimate in 2007 had been $2.49 billion.
The agency blamed the increase on poor previous estimates and acknowledged that reviews to support the initial estimate were not completed.
