NRC Accepts Application to Renew ABWR Design from GE Hitachi Nuclear Energy

LCG, February 24, 2011--GE Hitachi Nuclear Energy (GEH) yesterday announced that the U.S. Nuclear Regulatory Commission (NRC) has formally accepted GEH's application to renew the design certification for its Advanced Boiling Water Reactor (ABWR) technology. The application was submitted to the NRC in December.

GEH's ABWR design was certified for U.S. construction in 1997, and the certification is scheduled to expire in June 2012. With the renewal application, GEH is requesting to incorporate revisions and extend the certification for an additional 15 years.

A spokesperson for GEH stated, "We are committed to ensure our ABWR design remains certified for immediate commercial deployment as utilities evaluate their energy priorities.... We look forward to working with the NRC to help support a timely review of our application utilizing the NRC draft guidance issued earlier this year."

The ABWR design is currently licensed in the United States, Japan and Taiwan. The Generation III design is available to meet power generation needs ranging from 1,350 to 1,460 MW net. The first two of four ABWRs operating in Japan entered service in 1996 and 1997, and five more ABWRs are currently under construction in Japan and Taiwan.
