Nuclear Regulatory Commission.


10 CFR 2.206 request; receipt.


The U.S. Nuclear Regulatory Commission (NRC) is giving notice that by petition dated March 25, 2014 [sic], Mike Mulligan (the petitioner) has requested that the NRC take action with regard to the Vermont Yankee Nuclear Power Station (VY) and the Kewaunee Power Station (KPS), which have been permanently shut down and are currently undergoing decommissioning. The petitioner's requests are included in the SUPPLEMENTARY INFORMATION section of this document.

On March 25, 2014 [sic], the petitioner requested that the NRC take action with regard to VY and KPS (ADAMS Accession No. ML15090A487). On July 7, 2015, the petitioner provided supplemental information via email (ADAMS Accession No. ML15198A091). The petitioner requested a number of actions including:

  • Conduct exigent and immediate full-scale ultrasonic inspections on the VY and the KPS reactor pressure vessels (RPVs), with similar or better technology, as conducted on the RPVs at Doel 3 and Tihange 2, which revealed thousands of cracks;
  • Take large borehole samples out of both the Vermont Yankee and Kewaunee RPVs and transport them to a respected metallurgic laboratory for comprehensive offsite testing;
  • Issue an immediate NRC report and hold a public meeting on any identified vulnerabilities; and
  • Ultrasonically test all RPVs in U.S. plants within 6 months, if distressed and unsafe results are discovered at VY or KPS.

As the basis for this request, the petitioner states that the requested actions should be taken to determine whether foreign operating experience—specifically several thousand cracks that have been discovered during testing on the Doel 3 and Tihange 2 RPVs—could have implications on U.S. operating reactors.

The request is being treated pursuant to section 2.206, “Requests for action under this subpart,” of Title 10 of the Code of Federal Regulations (10 CFR) of the Commission's regulations. The request has been referred to the Director of the Office of Nuclear Reactor Regulation.

The petitioner met with the Petition Review Board on May 19, 2015, to discuss the petition; the transcript of that meeting is an additional supplement to the petition (ADAMS Accession No. ML15181A127). The results of that discussion and the July 7, 2015, supplemental email were considered in the board's determination regarding the petitioner's request for immediate action and in establishing the schedule for the review of the petition.

The NRC has denied the petitioner's request to conduct immediate ultrasonic inspections at VY and KPS because of the following reasons. Both the identified facilities have ceased operations and would not be subject to an enforcement-related action (i.e., to modify, suspend, or revoke the license). In addition, the NRC issued Information Notice (IN) 2013-19, “Quasi-Laminar Indications in Reactor Pressure Vessel Forgings,” on September 22, 2013 (ADAMS Accession No. ML13242A263). The purpose of this IN was to inform industry of the quasi-laminar indications that were identified in 2012, at two European commercial nuclear power plants. These indications were identified during the ultrasonic inspections that were performed on the RPV forgings.

As provided by 10 CFR 2.206, appropriate action will be taken on the remaining requests within a reasonable time.
