REGULATORY AUDIT
SUMMARY
FOR LICENSE AMENDMENT REQUEST TO REVISE EMERGENCY ACTION LEVEL SCHEMES (CAC NOS. MF9836-MF9840; EPID L-2017-LLA-0237)
Dear Mr. Hanson:
By application dated May 31, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17164A149), as supplemented by letter dated January 31, 2018 (ADAMS Accession No. ML18037A653), Exelon Generation Company, LLC (Exelon, the licensee) submitted a license amendment request (LAR) for Calvert Cliffs Nuclear Power Plant, Units 1 and 2; Nine Mile Point Nuclear Station, Units 1 and 2; and R. E. Ginna Nuclear Power Plant. The amendments would revise the emergency plans by changing the emergency action level schemes for these facilities. The proposed changes are based on the Nuclear Energy lnstitute's (NEl's) guidance in NEI 99-01, Revision 6, "Development of Emergency Action Levels for Non-Passive Reactors," which was endorsed by the U.S. Nuclear Regulatory Commission (NRC) by letter dated March 28, 2013 (ADAMS Accession No. ML12346A463).
By letter dated July 18, 2017 (ADAMS Accession No. ML171948082), the NRC staff informed Exelon of its plan to conduct a regulatory audit of nondocketed information to support the staff's review of the LAR. The audit was performed using an online reference portal.
The purpose of this letter is to inform Exelon that the NRC staff has completed its regulatory audit and no longer needs access to the online reference portal which was established for this LAR. A summary of the staff's audit is enclosed but the staff's review of the LAR is ongoing.
If you have any questions, please contact me by e-mail at Blake.Purnell@nrc.gov or by phone at (301) 415-1380.

By letter dated July 18, 2017 (ADAMS Accession No. ML171948082), the NRC staff informed Exelon of its plan to conduct a regulatory audit of nondocketed information to support the staff's review of the LAR. The audit was performed using an online reference portal. The purpose of the audit was to verify assumptions and input used to calculate specific monitor thresholds in the proposed EALs.
The NRC staff reviewed calculations, analysis, and supporting documentations related to radiological effluent and containment radiation monitor thresholds in the proposed EALs. The specific documents reviewed were used to establish the thresholds for radiological effluent monitors in EALs RU 1, RA 1, RS 1, and RG 1 and the thresholds for containment radiation monitors in EALs FC3, RC3, CS6, and CG6. The complete list of documents reviewed is listed in the table below.
