The U.S. Nuclear Regulatory Commission (NRC or the Commission) is giving notice that by petition dated April 16, 2012; the Natural Resources Defense Council, Inc. (the petitioner) has requested that the NRC take action with regard to Indian Point Nuclear Generating Unit No. 2. The petitioner's requests are included in the SUPPLEMENTARY INFORMATION section of this document.

On April 16, 2012, the petitioner requested that the NRC take action with regard to Indian Point Nuclear Generating Unit No. 2. The petitioner requests that the NRC order the licensee of Indian Point Nuclear Generating Unit No. 2 to remove the passive autocatalytic recombiners (PARs) because the PAR system could have unintended ignitions in the event of a severe accident, which, in turn, could cause a hydrogen detonation. As the basis for this request, the petitioner references experimental data where PARs malfunction in environments containing high concentrations of combustible gases by having ignitions. The petitioner asserts that the PARs could be overwhelmed by the production of hydrogen following a severe reactor accident and a resulting ignition could lead to a detonation that challenges the structural integrity of the containment structure.

The request is being treated pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 2.206, “Requests for Action Under this Subpart,” of the Commission's regulations. The request has been referred to the Director of the Office of Nuclear Reactor Regulation (NRR). As provided by 10 CFR 2.206, appropriate action will be taken on this petition within a reasonable time. The petitioner met with the NRR petition review board on June 14 (transcript at ADAMS Accession No. ML12300A412) and September 12, 2012 (transcript at ADAMS Accession No. ML12300A428), to discuss the petition. The results of that discussion were considered in the board's determination regarding the petitioner's request for action and in establishing the schedule for the review of the petition. A copy of the petition is available for inspection under ADAMS Accession No. ML12108A052.

Dated at Rockville, Maryland, this 16th day of November 2012.

For the Nuclear Regulatory Commission.

Eric J. Leeds,

Director, Office of Nuclear Reactor Regulation.
