==Dear Mr. Hanson:==
I am writing to acknowledge receipt of Exelon Generation Company, LLCs (Exelons) letter dated October 16, 2019, in response to U.S. Nuclear Regulatory Commission (NRC) Inspection Report 05000244/2019010 issued on September 18, 2019 (ML19261A083)1.
 
In the letter (ML19291A173), Exelon contested a finding of very low safety significance (Green)
and associated Notice of Violation (NOV 05000244/2019010-02) issued to R. E. Ginna Nuclear Power Plant (Ginna). The finding and violation involved a failure by Ginna to design or ensure that in the event of a design-basis earthquake, the safety-related Emergency Diesel Generator (EDG) Motor Control Centers (MCCs) H and J would not be lost due to an electrical circuit fault in the non-safety-related sump pump motors. Exelon stated that Ginna met the NRC's standards in effect at the time of its construction as well as those in effect at the time of Application for Full-Term Operating License (1972) and as such, Exelon views that the NOV is unwarranted and should be rescinded. Additionally, Exelon believes that the position reflected in the inspection report constitutes a backfit and asks that the NRC assess these concerns consistent with agency backfitting processes. The NRC intends to review Exelons response and provide a letter documenting the basis for any decision relative to the disputed NOV and backfitting.
 
In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available

Dear Mr. Hanson:

I am writing to acknowledge receipt of Exelon Generation Company, LLCs (Exelons) letter dated October 16, 2019, in response to U.S. Nuclear Regulatory Commission (NRC) Inspection Report 05000244/2019010 issued on September 18, 2019 (ML19261A083)1.

In the letter (ML19291A173), Exelon contested a finding of very low safety significance (Green)

and associated Notice of Violation (NOV 05000244/2019010-02) issued to R. E. Ginna Nuclear Power Plant (Ginna). The finding and violation involved a failure by Ginna to design or ensure that in the event of a design-basis earthquake, the safety-related Emergency Diesel Generator (EDG) Motor Control Centers (MCCs) H and J would not be lost due to an electrical circuit fault in the non-safety-related sump pump motors. Exelon stated that Ginna met the NRC's standards in effect at the time of its construction as well as those in effect at the time of Application for Full-Term Operating License (1972) and as such, Exelon views that the NOV is unwarranted and should be rescinded. Additionally, Exelon believes that the position reflected in the inspection report constitutes a backfit and asks that the NRC assess these concerns consistent with agency backfitting processes. The NRC intends to review Exelons response and provide a letter documenting the basis for any decision relative to the disputed NOV and backfitting.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available

Designation refers to an Agencywide Documents Access and Management System (ADAMS) accession number. Documents referenced in this letter are publicly available using the accession number in ADAMS at https://adams.nrc.gov/wba/. For problems with ADAMS, please contact the NRCs Public Document Room (PDR) reference staff at 1-800-397-4209; 301-415-4737, or by e-mail to pdr.resource@nrc.gov Records component of the NRCs Agencywide Documents Access and Management System (ADAMS).
