Revised Mitigating Strategies Assessment Report for Flooding Cooper Nuclear Station, Docket No. 50-298, DPR-46 NPPD letter, "Mitigating Strategies Assessment Report for Flooding,"
dated April 27,2017
Dear Sir or Madam:
In the Reference, Nebraska Public Power District (NPPD) submitted the Mitigating Strategies Assessment (MSA) for the reevaluated flood hazard for Cooper Nuclear Station (CNS). As a result of an audit discussion with the Nuclear Regulatory Commission (NRC) on June 7, 2017, and further engineering
- analysis, NPPD determined that CNS' primary strategy for coping with a beyond-design-basis external flooding event would be modified.
NPPD informed the NRC of this decision during a teleconference on September 18, 2017. The purpose of this letter is to provide Revision 1 to CNS' MSA for Flooding (Attachment 1). The revisions made to the MSA are shown by revision bar in the right hand margin. NPPD requests Attachment 1, which contains security-related information, be withheld from public disclosure in accordance with 10 CFR 2.390. A redacted version of CNS' revised MSA is provided as Attachment 2 and is suitable for public disclosure.
There are no new regulatory commitments contained in this correspondence.
Should you have any questions or require additional information, please contact Jim Shaw, Licensing
- Manager, at (402) 825-2788.
ATTACHMENT 1 TO THIS LETTER CONTAINS SECURITY-RELATED INFORMATION.
UPON SEPARATION FROM ATTACHMENT 1, THIS COVER LETTER AND ATTACHMENT 2 ARE DECONTROLLED.
