SUPPLEMENTARY INFORMATION: Notice is hereby given that the Director, Office of Nuclear Reactor Regulation, has issued a director's decision (ADAMS Accession No. ML15132A625) on a petition filed by the petitioner on July 29, 2011 (ADAMS Accession No. ML11213A030).

The petitioner requested that the NRC issue a demand for information (DFI) of the operating licenses of all GE BWRs that utilize the Mark I and Mark II primary containment designs.

The NRC sent a copy of the proposed director's decision to the petitioner and the licensees for comment on April 17, 2015 (ADAMS Accession No. ML12215A283). The petitioner and the licensees were asked to provide comments within 30 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 NRC staff received comments on the proposed director's decision from the petitioner by letter dated May 8, 2015 (ADAMS Accession No. ML15128A388). The NRC staff responses to the comments are attached to the director's decision.

The Director of the Office of Nuclear Reactor Regulation denies the petition because the NRC staff has reasonable assurance that the design and operation of SFP cooling systems for BWRs with Mark I and II containment designs provide adequate assurance of public

health and safety and satisfy current regulations. The concern associated with development of harsh environmental conditions following a beyond-design-basis event that induces a sustained loss of spent fuel pool forced cooling was resolved through the issuance of orders and implementing guidance associated with the lesson-learned as a result of the Fukushima Dai-ichi accident. The reasons for this decision are explained in the director's decision (DD-15-11) pursuant to section 2.206 of title 10 of the Code of Federal Regulations (10 CFR), 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.

Dated at Rockville, Maryland, this 2nd day of November 2015.

For the Nuclear Regulatory Commission

William M. Dean,

Director, Office of Nuclear Reactor Regulation.
