Notice is hereby given that the Director, Office of Nuclear Reactor Regulation, has issued a director's decision (ADAMS Accession No. ML15128A349) on the petition filed by the petitioner on June 21, 2012 (ADAMS Accession No. ML12180A124).

The petitioner requested that the NRC revoke the license of Omaha Public Power District (OPPD, the licensee) to operate FCS. As the basis of the request, the petitioner raised the following issues: (1) Licensee event report submitted September 10, 2012, showed a support beam was not within allowable limits for stress and loading (ADAMS Accession No. ML12255A038); (2) flood protection measures at FCS are inadequate and create an ongoing, high risk danger to public safety; (3) the flood risks of the six dams upstream of FCS are either unevaluated or unresolved, and (4) the 614 primary reactor containment electrical penetration seals containing Teflon identified at FCS, a material that could degrade during design-basis accident conditions.

On August 29, 2011, the petitioner participated in a teleconference with the NRC's Petition Review Board. The meeting provided the petitioner an opportunity to provide additional information and to clarify issues cited in the petition. The transcript for that meeting is available in ADAMS under Accession No. ML11256A036. The petitioner provided supplemental material in support of the petition on August 22 and 27, November 19, and December 16, 17, and 20, 2012 (ADAMS Accession Nos. ML12240A099, ML12240A162, ML12250A714, ML12352A279, ML12352A221, and ML13109A240, respectively).

The NRC sent a copy of the proposed director's decision to the petitioner and the licensee for comment on April 15, 2015 (ADAMS Accession Nos. ML15063A047 and ML15063A050, respectively). The petitioner and the licensee were asked to provide comments within 14 days on any part of the proposed director's decision that was considered to be erroneous or any issues in the petition that were not addressed. The staff did not receive any comments on the proposed director's decision.

The Director of the Office of Nuclear Reactor Regulation has determined that the request, to revoke the operating license for FCS, be denied. The reasons for this decision are explained in the director's decision DD-15-04 pursuant to 10 CFR 2.206 of the Commission's regulations.

The NRC will file a copy of the director's decision with the Secretary of the Commission for the Commission's review in accordance with 10 CFR 2.206. As provided by this regulation, the director's decision will constitute the final action of the Commission 25 days after the date of the decision unless the Commission, on its own motion, institutes a review of the director's decision in that time.
