Supplementary Response to Request for Additional Information Regarding EPRI Report 1022909, "Benchmarks for Quantifying Fuel Reactivity Depletion Uncertainty"Project Number: 689

DearMr. Benney:

On behalf of the nuclear energy industry, the Nuclear Energy Institute(NEI) 1is providing asupplementaryresponse to the Request for Additional Information Questions related to EPRI Report 1022909 that were provided by the NRC to NEI via letter dated February 4, 2016 [Ref. 1].This EPRI Report supportsthe guidance providedin NEI 12-16, Guidance for Performing Criticality Analyses of Fuel Storage at Light-Water Reactor Power Plants,Revision 2,which was submitted to the NRC on January 9, 2017[Ref. 2]

1The Nuclear Energy Institute (NEI) is the organization responsible for establishing unified industry policy on matters affectin g the nuclear energy industry, including the regulatory aspects of generic operational and technical issues.NEI's members include all entities licensed to operate commercial nuclear power plants in the United States, nuclear plant designers, major architect/engineering firms, fuel cycle facilities, nuclear materials licensees, and other organizations and entities involved in the nuclear energy industry.

Mr.Brian J. BenneyJanuary 9, 2017 Page 2We look forward to receiving the draft SER for these reports to support inclusion in the final version of NEI 12-16.EPRI plans to make available updated versions of EPRI Reports 1022909 and 1025203 no later than February 2017.I look forward to continuing to work with the NRC staff to finalize this important guidance documentin the first quarter of 2017.Please do not hesitate to contact me at any time with questions.Sincerely, Kristopher W. Cummings
