Fire at South Texas Project Nuclear Reactor Site – Just Before Re-licensing Hearing
Austin, TX A fire that shot 50 foot flames into the air erupted January 8th in the main transformer at the South Texas Project site near Bay City, Texas, about 90 miles southwest of Houston. Reactor 2, which was out of commission for five winter months in 2011-2012, has not been operating since the fire.
The fire occurred just one week prior to a hearing on re-licensing the two South Texas Project reactors, which will be held January 15th from 2-5 pm and 7-10 pm at the Bay City Civic Center, 201 Seventh St.
October 1, 2011
Judges have now allowed a full hearing on foreign ownership of the proposed reactors.

Nuclear Reactor Cost Estimates for South Texas Plants
In the figures released to date, NRG estimates the total costs for Units 3 and 4 at the South Texas Nuclear Project to be between $6.0 and 7.0 billion.*
Dr, Arjun Makhijani used methodology from Florida Power and Light estimates for similar reactors, plugging in data from CPS Energy in San Antonio. Makhijani estimates that the two proposed reactors would cost between $12.0 and $17.5 billion. (Shown in red)
Moody’s Investors’ Service estimates similar reactors between $13.5 and 16.2 billion.

* An article that appeared after this chart was prepared cited a figure of $8 billion.
