SUBJECT:

ISSUANCE OF RENEWED FACILITY OPERATING LICENSE NO. DPR-49 FOR DUANE ARNOLD ENERGY CENTER

Dear Mr. Costanzo:

The U.S. Nuclear Regulatory Commission (NRC) has issued Renewed Facility Operating License No. DPR-49 for the Duane Arnold Energy Center (DAEC). The NRC issued the renewed facility operating license based on the staff's review of your application dated September 30, 2008, as supplemented by letters submitted to the NRC through August 18, 2010. The technical specifications for DAEC were not amended as a result of the NRC's review.

Renewed Facility Operating License No. DPR-49 expires at midnight on February 21, 2034.

The technical basis for issuing the renewed license appears in NUREG-1955, "Safety Evaluation Report Related to the License Renewal of the Duane Arnold Energy Center,"

published in November 2010. The results of the environmental reviews related to the issuance of the renewed license appear in NUREG-1437, Supplement 42, "Generic Environmental Impact Statement for License Renewal of Nuclear Plants: Regarding Duane Arnold Energy Center-Final Report," published in October 2010.

Enclosure I contains Renewed Facility Operating License No. DPR-49 with attachments, Appendix A, "Technical Specifications," and Appendix B, "Additional Conditions." is a copy of the related Federal Register notice of issuance of the renewed license.

The original has been sent to the Office of the Federal Register for publication.

C. Costanzo If you have any questions regarding this issue, please feel free to contact me at 301-415-2277 or by e-mail at brian.harris2Anrc.gov.

7590-01-P UNITED STATES NUCLEAR REGULATORY COMMISSION DOCKET NO. 50-331 NEXTERA ENERGY DUANE ARNOLD, LLC DUANE ARNOLD ENERGY CENTER NOTICE OF ISSUANCE OF RENEWED FACILITY OPERATING LICENSE NO. DPR-49 FOR AN ADDITIONAL 20-YEAR PERIOD Notice is hereby given that the U.S. Nuclear Regulatory Commission (the Commission) has issued renewed facility operating license No. DPR-49 to NextEra Energy Duane Arnold, LLC (licensee), the operator of the Duane Arnold Energy Center (DAEC). Renewed facility operating license No. DPR-49 authorizes operation of DAEC by the licensee at reactor core power levels not in excess of 1912 megawatts thermal in accordance with the provisions of the DAEC renewed license and its technical specifications.

The notice also serves as the record of decision for the renewal of facility operating license No. DPR-49, consistent with Title 10 of the Code of Federal Regulations Section 51.103 (10 CFR 51.103). As discussed in the final Supplemental Environmental Impact Statement (FSEIS) for DAEC, dated October 2010, the Commission has considered a range of reasonable alternatives that included generation from oil, wind, solar, hydropower, geothermal, wood waste, municipal solid waste, other biomass-derived fuels, fuel cells, delayed retirement, and conservation measures. The factors considered in the record of decision can be found in the supplemental environmental impact statement (SEIS) for DAEC.

DAEC is a boiling-water reactor located in Palo, Iowa. The application for the renewed license complied with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's regulations. As required by the Act and the Commission's regulations in 10 CFR Chapter 1, the Commission has made appropriate findings, which are set forth in the license. Prior public notice of the action involving the proposed issuance of the renewed license and of an opportunity for a hearing regarding the proposed issuance of the renewed license was published in the Federal Register on February 17, 2009 (73 FR 67895).

      • 4 lop E-mail: opa.resource(6nrc.gov Site: http://wwwnrc.ov No.10-219 December 16, 2010 NRC RENEWS OPERATING LICENSE FOR DUANE ARNOLD NUCLEAR POWER PLANT FOR AN ADDITIONAL 20 YEARS The Nuclear Regulatory Commission has renewed the operating license for the Duane Arnold Energy Center, located in Palo, Iowa, for an additional 20 years. The new license will expire on Feb. 21, 2034.

The decision to renew the license comes after thorough safety and environmental reviews of the application submitted Oct. 1, 2008, by the plant's operator, FPL Energy Duane Arnold. The Duane Arnold Energy Center is a boiling-water reactor, located about eight miles northwest of Cedar Rapids., Iowa.

The NRC held public meetings near the plant on March 24, 2009, April 22, 2009, and March 31, 2010, to discuss Duane Arnold's environmental review. In October, NRC staff concluded there were no environmental impacts that would preclude renewal of the license for environmental reasons.

After careful review of the plant's safety systems and specifications, the staff concluded that there were no safety concerns that would preclude license renewal and that the applicant had effectively demonstrated the capability to manage the effects of plant aging. In addition, NRC conducted inspections of the plant to verify information submitted by the applicant. On Oct. 7, the Advisory Committee on Reactor Safeguards - an independent body of technical experts that advises the Commission - issued its recommendation that license renewal for Duane Arnold should be approved.

The safety and environmental review reports, application and letters relating to the Duane Arnold license renewal are available on the NRC website at:

htt://www.nrc.gov/reactors/op~erating/licensin g/renewal/applications/duane-arnold-energy-center.html.

The Duane Arnold license represents the 6 1St reactor license renewed by the NRC. A complete listing of renewal applications can be found on the NRC website at:

20-year license extension approved for Duane Arnold Energy Center I TheGazette Page 2 of (

The extension was approved by the Nuclear Regulatory Commission after a 26-month review that concluded there were no environmental impacts that would preclude renewal of the license for environmental reasons.

The plant north of Palo generates enough power to supply 600,000 homes and employs 600. It would have been forced to close in 2014 had the license not been extended by the Nuclear Regulatory Commission.

"This is an important milestone for employees at Duane Arnold," plant spokeswoman Renee Nelson said. "Our employees were excited when we filed for license extension back in 2008 and this brings that effort to a a conclusion."

Sierra Club of Iowa Attorney Wallace Taylor of Cedar Rapids said he is strongly considering legal action to block the extension after reviewing comments submitted by the United States Environmental Protection Agency.

"I think the EPA comments give us some strong support," Taylor said.

The Sierra Club's concerns included plant safety, water resource issues with the Cedar River and Pleasant Creek, on-site storage of spent nuclear fuel rods. Taylor said he was glad that the EPA shared his concerns about the scope of the review, believing it should have looked at whether there were more efficient and environmentally sound options to continuing to operate the plant for 20 years.

Florida-based NextEra Energy acquired the 70 percent majority stake in the plant from Alliant Energy when Alliant decided it didn't want to go through the license extension process several years ago. The extension was a four-year process that cost $20 million.

Nelson said the license renewal process included extensive inspections of plant equipment and replacement of equipment when needed.

"This doesn't mean we will relax oour standards for safety and equipment reliability going forward," Nelson said.

The generating capacity of the boiling water reactor-powered generating station has been increased by 50 megawatts since it was placed in service in 1974.

Duane Arnold Energy Center is Iowa's only nuclear power plant.
