Project Overview

The staff of the U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities for the GEH BWRX-300 small modular reactor (SMR), including the review of a selected number of licensing topical reports (TRs) and technical design White Papers (WPs) describing the design approaches and methodologies for the BWRX-300 SMR in advance of a 10 CFR Part 50 or Part 52 application. The BWRX-300 is a ~300 MWe water-cooled, natural circulation SMR with a passive safety system.

Draft LTR "Readiness Assessment"

During the course of its review of the License TRs, the NRC staff may issue requests for additional information (RAIs) that is needed to determine the acceptability of methods and approaches described in each License TR. The applicant's responses to RAIs may result in revisions to an License TR and the issuance of an License TR supplement that incorporates all changes.

Additional information can be obtained from ADAMS (99900003).
