Per Reference 1, Union Electric Company (Ameren Missouti) submitted a 1icense amendment request for an emergency action level (EAL) scheme change for Callaway Plant (Callaway).

ULNRC-06488 February 20, 2019 Page 2 of 5
                      - Hazardous event affecting a SAFETY SYSTEM needed for the cmTent operating MODE: Alert,"
and SA9.1, "System Malfunction - Hazardous event affecting a SAFETY SYSTEM needed for the cunent operating MODE: Alert" (including addition of a new definition for the tenn "Loss of Safety Function (LOSF)" and re-definition of the tenn "Visible Damage"), along with deletion of Initiating Condition (IC) HG 1 and associated EAL HG 1.1, "Hazard - HOSTILE ACTION resulting in loss of physical control of the facility: General Emergency," in connection with the Callaway Plant Radiological Emergency Response Plan (RERP).
Per Reference 2, the NRC staff transmitted a request for additional information (RAI) needed to facilitate the technical review being conducted by the Office of Nuclear Security and Incident Response/ Division of Preparedness and Response/Reactor Licensing Branch (NSIR/DPR/RLB).
Through discussion with the NRC staff during a telephone conference on December 18, 2018, Ameren Missouri proposed to revise its original LAR such that the verbiage that had been provided for the requested EAL changes regarding "Loss of Safety Function" would be replaced with verbiage that is consistent with Reference 3, as modified in accordance with the NRC staff guidance provided in Reference 4.
When the originally proposed verbiage was replaced in order to effect alignment with the noted NRC-recognized guidance, Ameren Missouri also considered additional NRC-recognized guidance, as provided in Reference 5, which is applicable to the proposed changes. Changes per the latter would add clarification text to the Bases for EALs CA6.1 an SA9.1 that is consistent with Reference 5, including examples of systems and components to which the clarification applies.
All of these changes require revision of the originally proposed changes, and consequently, this letter is hereby submitted as a supplement to the original LAR. This letter also serves to provide a response to the Reference 2 RAI, notwithstanding the applicability of the RAI questions/requests to the originally proposed changes.
All required infonnation pertaining to the new changes and RAI response is provided in the attachments to this letter. Specifically, the response to the RAI is provided in Attaclunent 1 to this letter, and Attaclunents 2, 3, and 4, respectively, provide a revised evaluation of proposed EALs, revised mark-ups of proposed Callaway EAL Technical Bases Document affected pages, and revised clean copies of proposed Callaway EAL Technical Bases Document affected pages. A revised clean copy of the proposed Emergency Action Level Classification Matrix is also provided for infonnation as Attaclunent 5. The supplemental material that is provided in Attaclunents 2, 3, 4, and 5 supersedes material that had been submitted per Reference 1.
This submittal does not contain new commitments. For any questions concerning this letter, please contact Mr. Tom Elwood at 314-225-1905 .
