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 numerous licensing topical reports (LTRs) 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 passive safety systems. As the tenth evolution of the Boiling Water Reactor (BWR), the BWRX-300 represents the simplest, yet most innovative BWR design since GE began developing nuclear reactors in 1955. The design of the BWRX-300 is based on the U.S. NRC-licensed, 1,520 MWe Economic Simplified BWR and is designed to provide clean, flexible baseload electricity generation.
Topical Reports for the GEH BWRX-300 SMR Design

||Scheduled AFSER for December 23,
During the course of its review of the LTRs, the NRC staff may issue requests for additional information (RAIs) that is needed to determine the acceptability of methods and approaches described in each LTR. The applicant's responses to RAIs may result in revisions to an LTR and the issuance of an LTR supplement that incorporates all changes.
Additional information can be obtained from ADAMS using a search by docket number 99900003.
