UPDATE 3-TVA ups Watts Bar reactor cost to $4.5 bln, online '15

* Reactor cost up from $2.5 billion estimate
    * Project was expected to start in 2012
    * Bellefonte's new reactor likely also to be delayed

    April 5 (Reuters) - U.S. government-owned Tennessee Valley
Authority (TVA) said on Thursday it now sees the new reactor at
the Watts Bar 2 nuclear power plant in Tennessee online between
September and December 2015 at a higher estimated cost of $4
billion to $4.5 billion.	
    In February, TVA said the 1,180-megawatt Watts Bar 2 project
was running over budget and behind schedule.	
    Watts Bar is one of five new reactors the industry expects
to complete by 2020 as part of a slow-moving nuclear renaissance
in the United States.	
    The others are the two reactors Southern Co is
building at Vogtle in Georgia and the two that Scana Corp
 is constructing at Summer in South Carolina.	
    "Watts Bar Unit 2 remains a cost-effective solution for
meeting the region's base load power needs with clean energy at
a competitive rate," Tom Kilgore, TVA president and CEO, said in
a release.	
    "Even with the estimated added cost, Unit 2 at Watts Bar
will still be a competitive, reliable generation source for the
people of the Tennessee Valley," Kilgore said.	
    TVA decided in 2007 to complete the second reactor at Watts
Bar to help meet the region's growing demand for power. The unit
was expected to enter service in 2012 at a cost of about $2.5
billion. 	
    "Our estimates on time and cost were wrong," Kilgore said.
"While our intentions were well founded, our execution and
progress reviews were not."	
    After TVA loads the fuel into Watts Bar 2, the company has
said in the past that it plans to start work to complete another
reactor at the Bellefonte nuclear site in Alabama.	
    TVA decided in August that it would complete the 1,260-MW
Bellefonte 1 reactor. In the past, TVA said the project would
cost about $4.9 billion and could enter service by 2020.	
    The company has said it would take about six years of
construction time to finish Bellefonte 1, which was already
about 55 percent complete. 	
    But the ultimate cost and timing for Bellefonte depends on
work at Watts Bar 2. 	
    TVA started work on the Watts Bar and Bellefonte reactors in
the 1970s but put both projects on hold in the next decade due
in part to a projected decrease in power demand. 	
    TVA has blamed the Watts Bar 2 delays in part on expected
changes to safety and other rules by the U.S. Nuclear Regulatory
Commission following last year's Fukushima nuclear accident in
Japan. 	
    Last month, TVA said that of the 900 contractors supporting
the Bellefonte project, it would cut 430 positions. 	
    TVA said the contractors worked primarily for engineering
firms, including French nuclear conglomerate Areva SA
, one of the main companies involved in the project. 	
    TVA did not disclose financial details about the job
reductions.
