Slide 1: Prairie Island Nuclear Generating Plant Public Meeting
Prairie Island Nuclear Generating Plant Red Wing, MN Extended Power Uprate & Additional Dry Cask Storage Certificates of Need and Site Permit Applications Public Meeting - September 10, 2008
Slide 2: Overview of Prairie Island
Overview of Prairie Island Pressurized Water Nuclear Reactor. 2 units (550 MW each). Operational in 1973 and 1974. Provides base load energy and capacity 24 hours per day, 7 days per week. Shuts down every 18 to 20 months for refueling at which time a little over 1/3rd of the fuel assembli

Slide 4: Our Proposals
Our Proposals Xcel Energy is asking the Minnesota Public Utilities Commission to approve two separate Certificates of Need: 1. Additional dry cask storage to support the continued operation of Unit 1 until 2033 and Unit 2 until 2034; 2. Increase the electrical generation capabilities of the plant
Slide 5: Summary of Dry Cask Needs
Summary of Dry Cask Needs Prairie Island’s Independent Spent fuel Storage Installation (ISFSI) is currently designed, constructed and licensed by NRC to store 48 dry casks. Currently there are 24 dry casks stored at the ISFSI. State authorization is for enough dry storage to operate to 2014, e

Slide 7: Additional Dry Cask Storage (Docket No. E002/CN-08-510)
Additional Dry Cask Storage (Docket No. E002/CN-08-510) Storage beyond 48 dry casks will be accomplished by utilizing the remaining capacity of the current installation and by adding concrete pads within the existing ISFSI. Up to thirty-five (35) additional casks may be needed to continue to ope

Slide 10: Additional Dry Cask Storage Project Impacts
Additional Dry Cask Storage Project Impacts Impacts of additional dry cask storage are minimal: — Up to 35 additional dry casks may be added to existing ISFSI over the next 20 years. — Construction will be within the existing footprint of the existing ISFSI. — No change in noise levels or air qual
Slide 11: Project Benefits
Project Benefits Continued operation of Prairie Island an additional 20 years provides significant benefits to Xcel Energy customers and local economy. Utilizes an existing site – does not require new power plant construction. People and environment benefit from carbon reductions due to less r
Slide 12: What if Additional Dry Cask Storage CON is denied?
What if Additional Dry Cask Storage CON is denied? Unit 1 will shut down in 2013 and Unit 2 in 2014 and decommissioning process would begin. To decommission the plant, Xcel Energy would be required to file a CON for 39 additional dry casks to store the used fuel in the reactor and the storage po
Slide 13: Extended Power Uprate (Docket No. E002/CN-08-509)
Extended Power Uprate (Docket No. E002/CN-08-509) The additional 164 MW will be accomplished by a process called an “extended power uprate” (EPU). The additional power is achieved by: — Increasing the amount of heat produced in the reactor, which results in more steam being produced by the steam
Slide 14: Changes to Plant Operation
Changes to Plant Operation Generally, operation at the plant will not change. The reactor will be operated at a higher thermal power level. Balance-of–plant changes to more efficiently convert steam into electricity including: — New high pressure turbines — New turbine control valves — Main ge
Slide 15: Extended Power Uprate Project Impacts
Extended Power Uprate Project Impacts Impact of extended power uprate is minimal: — The plant’s existing environmental footprint will not increase. — The plant will continue to operate within limits of all existing air and water permits. — Will use slightly more water. — Will slightly increase wat
Slide 16: Project Benefits
Project Benefits Financial - Significant benefits to customers and local economy. Environmental – Reduction in carbon and other emissions due to less operation of existing fossil fuel plants. — Utilizes an existing site – does not require new power plant construction. — Carbon reductions from av
Slide 17: Conclusion
Conclusion The Prairie Island facility plays an integral role in the reliability and strength of our overall system. Increasing its power generation capabilities will assist Xcel Energy in meeting our goals for cost-effective, environmentally-friendly energy for our customers. Neither project
