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. ML14265A084). 

Dated at Rockville, Maryland, 20th day of 

November 2014. 

For the Nuclear Regulatory Commission.

Chief, Licensing Branch 3, Division of New 

Reactor Licensing, Office of New Reactor.
