US-APWR Pre-Application Review

The U.S. Nuclear Regulatory Commission (NRC) has a policy of encouraging early discussions (prior to submission of a license application) with potential applicants (such as utilities and reactor designers) to offer licensing guidance and to identify and resolve potential licensing issues early in the licensing process. Consistent with that policy, from July 2006 through September 2007, the NRC staff and representatives of Mitsubishi Heavy Industries, Ltd. (MHI) engaged in a variety of pre-application review activities associated with possible certification of a standard design for the U.S. Advanced Pressurized-Water Reactor (US-APWR).

Pre-Application Public Meetings

During the pre-application period for a design certification, the NRC holds public meetings with potential applicants to discuss advanced reactor designs to identify (1) major safety issues that could require Commission policy guidance to the staff, (2) major technical issues that the staff could resolve under existing regulations or NRC policy, and (3) the research needed to resolve identified issues. For more specific information about public meetings related to the US-APWR pre-application review activities, see the following pages:
