Mr. Langley, Good afternoon. You submitted a petition, on behalf of Public Watchdogs, requesting action under 10 C.F.R. 2.206 that included, among other requests, that the NRC order the San Onofre Nuclear Generating Station (SONGS) licensee, Southern California Edison (SCE) to immediately suspend decommissioning operations at SONGS and that the NRC order the SCE to take immediate actions to preclude flooding of the Independent Spent Fuel Installation (ISFSI) at the site. The justification provided in your petition for these immediate action requests was an assertion that the SONGS ISFSI is operating in an unanalyzed condition, because some of the potential consequences of flooding of the ISFSI have not been considered.

The NRC staff reviewed these immediate action requests and has concluded, in accordance with Sections II.B.1 and III.B.1 of Management Directive (MD) 8.11, that the requests do not warrant immediate action. The NRC staff has determined that the scenario, described in the petition, of an earthquake and tsunami leading to the submersion under water or covering by debris of the ISFSI at SONGS, while possible, would not lead to the specific consequences presented in the petition.

The effects of inundation of the SONGS ISFSI with floodwater or burial by debris and, specifically, the reactions of the spent fuel canisters to such conditions, are evaluated in the Final Safety Analysis Report (FSAR) for the Holtec HI-STORM UMAX dry cask storage system (ML18192B094). The NRC staff has reviewed the FSAR for the UMAX system and found that the system meets all applicable NRC regulations.

As such, the NRC staff has determined that the decommissioning activities at SONGS do not constitute an immediate threat to public health and safety.

Consistent with the 2.206 process, the Staff is proceeding with its evaluation of whether the petition you submitted meets the MD 8.11 acceptance criteria for review. We will contact you once the Staff has made that initial determination.

If you have any questions regarding this e-mail, please feel free to contact me at Chris.Bajwa@nrc.gov.
