Pursuant to Confirmatory Order EA-14-193 (Reference 1), Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, provided in Reference 2 a project plan for restoring 10 CFR 72 compliance to dry shielded canisters (DSCs) designated 11 through 16 at the Monticello Nuclear Generating Plant.

Action 3 of the Confirmatory Order requires the following:

Within 180 days after submittal of the DSCs 11 through 16 project plan, Xcel Energy shall submit a letter to the Director, DNMS, Region III, regarding progress under the plan and any non-editorial changes to the plan. A letter providing a progress update and any non-editorial changes shall be provided every 360 calendar days thereafter to the Director, DNMS, Region III, until the plan is completed.

Reference 3 provided the initial 180 day progress letter on the project plan. At the time the progress letter was submitted, NSPM anticipated submitting an exemption request for DSCs 11-15 as early as September 2017. Following input from multiple experts regarding structural, risk, and dose considerations for development of the exemption request, NSPM submitted the request on October 18, 2017 (Reference 4).

The exemption request is currently under review by NRC staff. NSPM received a Request for Additional Information (RAI) on March 6, 2018 (Reference 5), and provided a response to the RAI on April 5, 2018 (Reference 6). Subsequently, the NRC provided clarifying questions in regard to NSPMs RAI response on May 1, 2018 (Reference 7). Those questions were discussed during a teleconference between NSPM and members of the NRC staff on May 10, 2018 (Reference 8). During the teleconference, NSPM agreed to supplement its RAI response in Reference 6. That supplement was provided on May 31, 2018 (Reference 9).

The project plan detailed in Reference 2 and updated by Reference 3 continues on track for restoring 10 CFR 72 compliance for DSCs 11-15 by March 2020, as identified in the project plan.

If additional information is required, please contact Mr. Shane Jurek at (612) 330-5788.
