SUBJECT:

ADVANCED POWER REACTOR 1400 FINAL SAFETY EVALUATION FOR TOPICAL REPORT APR1400-F-A-TR-12004, REVISION 1, REALISTIC EVALUATION METHODOLOGY FOR LARGE-BREAK LOSS OF COOLANT ACCIDENT OF THE APR1400

Dear Mr. Kim:

The U.S. Nuclear Regulatory Commission (NRC) staff has prepared a final topical report (TR) safety evaluation (TRSE) for Topical Report APR1400-F-A-TR-12004, Revision 1, Realistic Evaluation Methodology for Large-Break Loss of Coolant Accident of the APR1400. This TRSE is also valid for the non-proprietary version of the TR. This action is supported by the letter dated June 15, 2018 (Agencywide Documents Access and Management System Accession No. ML18166A269), whereby the Advisory Committee on Reactor Safeguards agrees with the NRC staffs conclusions, within the limits and conditions that are specified in the TRSE. This evaluation is in support of the review of the APR1400 design certification application submitted by Korea Hydro and Nuclear Power Co., Ltd. (KHNP) and Korea Electric Power Corporation on December 23, 2014.

The staff requests that KHNP publish the accepted enclosed proprietary and non-proprietary versions of this TR within one month of receipt of this letter. The accepted versions shall incorporate this letter and the enclosed final TRSE after the title page. Also, they must contain historical review information, including NRC requests for additional information and your responses. The accepted versions of the TR shall include an -A (designated accepted) following the report identification number.

If the NRCs criteria or regulations change such that its conclusion that the accepted TR is invalidated, KHNP and/or the applicant referencing the TR will be expected either to revise and resubmit its respective documentation or to submit justification for continued applicability of the TR without revision of the respective documentation.

Document transmitted herewith contains sensitive unclassified information. When separated from the enclosure, this document is DECONTROLLED.
