It appears B&W is moving up the small modular reactor (SMR) ranks to be on of the first SMRs to realize a customer and construction. 

TVA continues to express interest in the mPower design and may want up to six of them by 2020. Good summary of the details at Cool Hand Luke.  TVA is committed by 2020 to generating at least half of all the electricity it sends to customers with noncarbon sources.  Nuclear is a logical choice especially with easier to build and finance SMRs.  We all love to love wind and solar but TVA will not meets its 50% goal with such inefficient power generation sources.  Discussion on the logic of wind and solar here.

-Proven ALWR design which will reduce regulatory review time
-Design Certification submittal in 2011 with approval expected in Q4 2012
-Letter of intent recieved from Tennessee Valley Authority (TVA) to begin the process of evaluating a potential lead plant site
