SUPPLEMENTARY INFORMATION: On August 24, 2005, in accordance with 
subpart B of 10 CFR part 52, GEH tendered its application for 
certification of the Economic Simplified Boiling-Water Reactor (ESBWR) 
standard plant design (ADAMS Accession No. ML052450245) with the NRC. 
The NRC staff issued a final safety evaluation report (FSER) for the 
ESBWR design in March 2011 (ADAMS Accession No. ML103470210). The NRC 
also published a proposed rule to certify the ESBWR design in the 
Federal Register on March 24, 2011 (76 FR 16549). The FSER and the 
proposed rule were based on the NRC's review of Revision 9 of the ESBWR 
design control document (DCD).
    In late 2011, while the NRC staff was preparing the final rule, 
issues were identified with the ESBWR steam dryer, a nonsafety-related 
component. These issues called into question certain conclusions in the 
staff's safety review. Publication of the FSER as a NUREG was delayed 
while the steam dryer design methodology was under review. The NRC 
issued requests for additional information (RAIs). Resolution of these 
issues required additional analyses by the applicant and review by the 
NRC staff in order for the NRC staff to conclude the design is 
acceptable for certification. Responses to all RAIs were received in 
December 2013. The Final Safety Evaluation Report was issued by the NRC 
as NUREG-1966 (ADAMS Accession No. ML14100A304) in April 2014 to 
document the NRC staff's technical review of the ESBWR design. 
Subsequently, the NRC issued an advanced supplemental safety evaluation 
report (SER) to address several matters identified by the NRC and 
revisions to the ESBWR DCD in Revision 10. The advanced supplemental 
SER was issued on April 27, 2014 (ADAMS Accession No. ML14043A134) and 
was referenced in a supplemental proposed rule published on May 6 2014 
(79 FR 25715; May 6, 2014). This supplement includes the NRC staff's 
safety review of the steam dryer issues (reactor pressure vessel 
internals), as well as: Protection of the offgas system within the 
turbine building; Bulletin 2012-01 and GDC 17; seismic analysis of fuel 
in spent fuel and buffer pools; ESBWR DCD Tier 1, ASME code definition; 
ESBWR DCD Tier 1, ASME code component design verification ITTAAC; and 
ESBWR DCD Tier 2, editorial corrections in Chapters 16 and 16B. On the 
basis of the evaluation described in the ESBWR FSER (NUREG-1966) and 
the supplemental FSER issued on September 24, 2014 (ADAMS Accession No. 
ML14328A238), the NRC staff concluded that the changes to the DCD (up 
to and including Revision 10 to the ESBWR DCD) were acceptable and that 
GEH's application for design certification met the requirements of 
Subpart B to 10 CFR part 52 that are applicable and technically 
relevant to the ESBWR standard plant design. The NRC then published a 
final rule to certify the ESBWR design in the Federal Register on 
October 15, 2014 (79 FR 61944). This document announces the 
supplemental final safety evaluation report was published as NUREG-
1966, Supplement 1 in September, 2014 (ADAMS Accession No. 

    Dated at Rockville, Maryland, 20th day of November 2014.
