B&W mPower™

Who:   Generation mPower LLC.

What:   Pre-application design certification interaction to discuss small modular reactor issues related to the Babcock & Wilcox (B&W) mPower™ design.

When:   Pre-application interactions began in July 2009. On April 14, 2014, B&W announced the restructuring of its small modular reactors program to focus on mPower technology development. B&W's press release may be found on their website at http://www.babcock.com/news-room/Pages/BW-Announces-Restructuring-of-Small-Modular-Reactor-Program.aspx. The date of tendering of a Design Certification application is to be determined.
